Description

Technical Field

[0001] This invention relates to the field of water environment treatment technology, and more specifically, to a water environment treatment pond and its usage method. Background Technology

[0002] With the acceleration of urbanization, a large amount of pollutants are discharged into water bodies, leading to seasonal or year-round black and odorous phenomena in urban rivers. The formation of black and odorous water bodies is mainly due to the severe lack of dissolved oxygen in the black silt deposited at the bottom of the riverbed. Organic matter decomposes under anaerobic conditions, producing black and odorous substances such as hydrogen sulfide, mercaptans, and ammonia, which are continuously released into the water body, causing water quality deterioration.

[0003] There are two main methods for treating polluted rivers. One is ex-situ treatment, which involves dredging to remove the black mud from the riverbed. This method is large-scale, easily damages the original habitat of the riverbed and benthic organisms, and the large amount of contaminated mud removed is difficult to transport and dispose of, posing a risk of secondary pollution. The second method is in-situ treatment, which involves setting up floating islands on the river surface and using aeration devices to blow gas into the bottom of the river to agitate the soft mud layer. Under the influence of river flow, a large amount of floating material generated by aeration will accumulate and settle downstream.

[0004] However, during the in-situ treatment process, the large amount of floating matter that accumulates downstream will not only further expand the scope of sewage, but will also seriously affect the treatment effect and efficiency of black and odorous rivers. Summary of the Invention

[0005] The problem addressed by this invention is how to effectively reduce the extent of sewage in riverbeds and improve the treatment effect and efficiency of black and odorous rivers.

[0006] To address the above problems, this invention provides a water environment treatment pond and its usage method.

[0007] In a first aspect, the present invention provides a water environment treatment pond, comprising: A water-floating body includes a water-blocking extension plate and an annular component, wherein the annular component has an annular groove, and the outer edge of the annular groove is fixedly connected to the bottom end of the water-blocking extension plate. A buoyancy mechanism is fixedly surrounded on the circumferential outer wall of the floating body on the water surface. The buoyancy mechanism contains a first gas to provide buoyancy to the floating body on the water surface. A dynamic enclosure, the top of which is fixedly connected to the outer wall of the annular component, and the bottom of which is used to sink into the soft soil of the riverbed to form a closed treatment space; An aeration pipe, one end of which is used to communicate with an aeration device, and the other end of which passes through the interior of the dynamic sealing cover and extends to the bottom of the dynamic sealing cover, is used to transport the second gas generated by the aeration device to the soft soil, so that the soft soil produces floating insoluble substances and is collected in the annular groove of the annular component. A drain pipe, which communicates with the annular member and is used to discharge insoluble substances located in the annular groove.

[0008] Optionally, the annular component includes a first annular plate portion and a second annular plate portion connected at an included angle, the inner edge of the first annular plate portion is fixedly connected to the outer edge of the second annular plate portion, and the annular groove is formed between the first annular plate portion and the second annular plate portion; the water-blocking extension plate is fixed to the outer edge of the first annular plate portion, and the outer wall of the second annular plate portion is fixedly connected to the dynamic sealing cover. The bottom of the annular groove is configured to be lower than the river surface of the riverbed when the water environment treatment pool is in operation.

[0009] Optionally, the buoyancy mechanism includes a plurality of corner buoyancy boxes arranged in a ring on the circumferential outer wall of the floating body on the water surface; The corner buoyancy tank includes a vertical liquid section and an inclined liquid section arranged at an angle. The inclined liquid section is fixed to the bottom of the vertical liquid section and is fixedly connected to the water-blocking extension plate. The interior of the vertical liquid section contains the first gas and forms a reserve buoyancy above the river surface of the riverbed. The inclined liquid section is fixedly connected to the outer wall of the first annular plate and contains the first gas and forms the main buoyancy below the river surface of the riverbed.

[0010] Optionally, the water environment treatment pond also includes biological placement boxes, and the floating body on the water surface also includes a submerged sleeve. The inner edge of the second annular plate is fixedly connected to the submerged sleeve, and a plurality of biological placement boxes are arranged in a ring at intervals on the inner wall of the submerged sleeve. The aeration pipe passes through the interior of the submerged sleeve and extends to the bottom of the dynamic closure.

[0011] Optionally, the dynamic enclosure includes a flexible soft layer and a plurality of rings connected vertically in sequence, the flexible soft layer covering the outside of the rings; the flexible soft layer is made of a water-resistant material or a water-permeable material.

[0012] Optionally, the water environment treatment pond also includes a counterweight structure, which is fixedly connected to the bottom of the dynamic enclosure. The counterweight structure is used to drive the bottom of the dynamic enclosure into the soft soil of the riverbed under the action of gravity.

[0013] Optionally, the floating body further includes multiple fixed piles and multiple guide rings. The inner edge of the second annular plate is provided with multiple positioning holes arranged in a ring. The multiple guide rings are installed at an annular interval on the outer wall of the submerged sleeve. The fixed piles pass through the positioning holes and the guide rings and are inserted into the soft soil of the riverbed. After the fixed piles are removed, the floating body floats up under the action of the buoyancy mechanism and drives the dynamic sealing cover to detach from the soft soil of the riverbed.

[0014] Optionally, the water environment treatment pool also includes a traction rope, the bottom end of which is fixedly connected to the bottom of the dynamic enclosure, and the top end of which extends above the floating body on the water surface. This traction rope is used to fold and store the dynamic enclosure by winding up the traction rope when the floating body moves.

[0015] Optionally, the water environment treatment pool also includes an operating platform, which is detachably installed on top of the floating body on the water surface.

[0016] Secondly, the present invention provides a method for using a water environment treatment pond, based on the water environment treatment pond described above, comprising the following steps: The floating body is placed in the target area of ​​the riverbed, and buoyancy is provided to the floating body through a buoyancy mechanism; The dynamic enclosure extends downwards and settles onto the soft soil of the riverbed, forming a closed treatment space; A second gas is blown into the bottom of the enclosed treatment space through the aeration pipe, causing the insoluble substances generated in the soft soil to float up, pass through the inside of the dynamic enclosure, and be collected into the annular groove of the annular component of the water surface floating body. The insoluble substances in the annular groove are drained through the drain pipe.

[0017] The beneficial effects of the water environment treatment pond and its usage method of the present invention are: The top of the dynamic enclosure is connected to the outer wall of the annular component of the floating body, while the bottom of the dynamic enclosure sinks into the soft soil of the riverbed. The floating body floats on the water surface thanks to the buoyancy provided by the first gas within the buoyancy mechanism. This creates a closed treatment space that extends from the water surface to the riverbed and is physically isolated from the external river. This fundamentally solves the problem of pollutants spreading with the water flow during in-situ treatment. Regardless of the amount of insoluble substances (such as flocculents and colloids) produced by subsequent aeration and agitation, they are confined within this closed treatment space, eliminating the risk of secondary pollution from downstream migration and expansion of the pollution range. Simultaneously, external water flow cannot enter, ensuring precise treatment within this space.

[0018] Within the enclosed treatment space created by the dynamic sealing hood, aeration pipes pass through the hood and extend to its bottom, directly injecting a second gas into the soft mud layer at the bottom of the riverbed. This action produces a dual effect: firstly, it significantly increases the dissolved oxygen in the soft mud layer, altering its anaerobic environment and fundamentally inhibiting the continuous formation of black and odorous substances such as hydrogen sulfide; secondly, the gas agitates the bottom sediment, causing previously deposited, organic-rich, insoluble substances to detach from the riverbed and float upwards under the influence of air bubbles. The "sealing" effect of the dynamic sealing hood ensures that these rising pollutants can only move vertically upwards, creating the preconditions for the subsequent targeted collection.

[0019] After the floating insoluble substances reach the vicinity of the water surface, they are collected at the bottom of the annular groove of the ring-shaped component. The outer edge of the ring-shaped component and the water-blocking extension plate fixed thereon are both above the water surface, forming a solid barrier that prevents the insoluble substances in the annular groove from re-entering the external water area. This achieves efficient and directional collection of pollutants, preparing high-concentration wastewater for subsequent pumping and drainage.

[0020] After a large amount of insoluble substances accumulate in the annular groove, they are actively extracted through a drainage pipe connected to the annular component. This removes the core substances causing black and odorous conditions in the form of concentrated liquid from the closed treatment space in an immediate and continuous manner, thereby rapidly and substantially reducing the toxicity inside the dynamic enclosure and effectively improving the treatment effect and efficiency of black and odorous rivers.

[0027] like Figures 1 to 3 As shown in the figure, an embodiment of the present invention provides a water environment treatment pond, comprising: A water surface float 100 includes a water-blocking extension plate 110 and an annular member 120. The annular member 120 has an annular groove 123, and the outer edge of the annular groove 123 is fixedly connected to the bottom end of the water-blocking extension plate 110. A buoyancy mechanism 200 is fixedly surrounding the circumferential outer wall of the water surface floating body 100. The buoyancy mechanism 200 contains a first gas to provide buoyancy to the water surface floating body 100. The top of the dynamic enclosure 500 is fixedly connected to the outer wall of the annular component 120, and the bottom of the dynamic enclosure 500 is used to sink into the soft soil of the riverbed to form a closed treatment space. An aeration pipe 600 has one end connected to an aeration device and the other end passing through the interior of the dynamic enclosure 500 and extending to the bottom of the dynamic enclosure 500. The aeration pipe 600 is used to transport the second gas generated by the aeration device to the soft soil so that the soft soil produces floating insoluble substances which are collected in the annular groove 123 of the annular member 120. A drain pipe 700 is connected to the annular member 120 and is used to discharge insoluble substances located in the annular groove 123.

[0028] Specifically, the water-blocking extension enclosure 110 can be a ring-shaped plate, belonging to the outermost structure of the water surface floating body 100. When working in the water environment treatment pond, the height of the water-blocking extension enclosure 110 is higher than the river liquid surface. Its core function is to act as an outer high-side retaining wall to prevent insoluble substances that have accumulated in the annular groove 123 from overflowing into the external open water area, ensuring the sealing and isolation effect of pollutants.

[0029] The water-blocking extension enclosure 110 can be a circular ring-shaped plate, a non-closed ring (e.g., C-shaped) ring-shaped plate, or a polygonal ring-shaped plate.

[0030] The dynamic enclosure 500 is the core component for constructing a closed governance space. The top of the dynamic enclosure 500 is fixedly connected to the outer wall of the ring component 120, the dynamic enclosure 500 extends downward as a whole, and the bottom of the dynamic enclosure 500 is used to sink into the soft soil of the riverbed.

[0031] The first gas in the buoyancy mechanism 200 can be a light gas such as air or carbon dioxide.

[0032] The aeration pipe 600 directly blows the secondary gas (usually air or oxygen) generated by the aeration device into the soil or mud layer of the riverbed. This operation specifically serves to: increase dissolved oxygen in the mud layer, disrupt the anaerobic environment, and inhibit the formation of blackening and odorous substances such as hydrogen sulfide at their source; and agitate the mud layer, causing deposited insoluble colloidal matter and flocculent matter (such as ferrous sulfide, organic residues, etc., with particle sizes mostly between 5-11 micrometers) to detach from the riverbed and float upwards under the attachment of air bubbles. The aeration device can employ a blower structure, and the secondary gas can be air or oxygen.

[0033] One end of the drain pipe 700 passes through the bottom end of the annular part 120 and communicates with the annular groove 123. The other end of the drain pipe 700 extends to the outside of the water environment treatment pool and can be connected to a water pump or sludge treatment equipment. The water pump can generate suction force to extract the insoluble substances in the annular groove 123 through the drain pipe 700; or, the drain pipe 700 can use a self-priming method to extract the insoluble substances in the annular groove 123 to the sludge treatment equipment for treatment.

[0034] In this embodiment, the top of the dynamic enclosure 500 is connected to the outer wall of the annular component 120 of the floating body 100, while the bottom of the dynamic enclosure 500 sinks into the soft soil of the riverbed. The floating body 100 floats on the water surface due to the buoyancy provided by the first gas in the buoyancy mechanism 200. This creates a closed treatment space that extends from the water surface to the riverbed and is physically isolated from the external river. This fundamentally solves the problem of pollutants spreading with the water flow during in-situ treatment. Regardless of how much insoluble matter (such as flocculents and colloids) is generated by subsequent aeration and agitation, it is confined within this closed treatment space, eliminating the risk of secondary pollution from downstream migration and expansion of the pollution range. Simultaneously, external water flow cannot enter, ensuring precise treatment of this space.

[0035] Within the enclosed treatment space created by the dynamic sealing hood 500, the aeration pipe 600 passes through the hood and extends to its bottom, directly injecting a second gas into the soft mud layer at the bottom of the riverbed. This action produces a dual effect: firstly, it significantly increases the dissolved oxygen in the soft mud layer, altering its anaerobic environment and inhibiting the continuous formation of black and odorous substances such as hydrogen sulfide at their source; secondly, the gas agitates the bottom sediment, causing the originally deposited, organic-rich, insoluble substances to detach from the riverbed and float upwards under the carry of the air bubbles. The "sealing" effect of the dynamic sealing hood 500 ensures that these floating pollutants can only move vertically upwards at this stage, creating the preconditions for the subsequent targeted collection.

[0036] After the floating insoluble substances reach the vicinity of the water surface, they are collected at the bottom of the annular groove 123 of the annular component 120. The outer edge of the annular component 120 and the water-blocking extension plate 110 fixed thereon are both above the water surface, forming a solid barrier to prevent the insoluble substances in the annular groove 123 from re-entering the external water area. This achieves efficient and directional collection of pollutants and prepares high-concentration wastewater for subsequent pumping and drainage.

[0037] After a large amount of insoluble matter accumulates in the annular groove 123, it is actively extracted through the drainage pipe 700 connected to the annular component 120. This removes the core substances causing black and odorous conditions in the form of a concentrated liquid from the closed treatment space in a timely and continuous manner. This results in a rapid and substantial reduction in toxicity within the closed treatment space inside the dynamic enclosure 500, effectively improving the treatment effect and efficiency of black and odorous rivers. After the drainage pipe 700 discharges the insoluble matter from the annular groove 123, the toxicity in the closed environment inside the dynamic enclosure 500 is reduced and can quickly recover under the influence of aquatic organisms or other auxiliary agents. Furthermore, after in-situ treatment, a small amount of mud settles but does not detach from its original location, making it applicable to in-situ experimental treatment of rivers and multiple remediation scenarios in specific river sections.

[0038] Optionally, combined Figure 2 and Figure 3 As shown, the annular component 120 includes a first annular plate portion 121 and a second annular plate portion 122 connected at an included angle. The inner edge of the first annular plate portion 121 is fixedly connected to the outer edge of the second annular plate portion 122, and the annular groove 123 is formed between the first annular plate portion 121 and the second annular plate portion 122. The water-blocking extension plate 110 is fixed to the outer edge of the first annular plate portion 121, and the outer wall of the second annular plate portion 122 is fixedly connected to the dynamic sealing cover 500. The bottom of the annular groove 123 is configured to be lower than the river surface of the riverbed when the water environment treatment pool is in operation.

[0039] Specifically, the annular component 120 can be a triangular cross-section ring with unequal heights. This unequal-height triangular cross-section ring has a triangular cross-section, with a first annular plate portion 121 (outer higher side) and a second annular plate portion 122 (inner lower side), forming an annular groove 123 between them. The outer edge of the annular groove 123 (i.e., the top of the first annular plate portion 121) is fixedly connected to the bottom end of the water-blocking extension enclosure 110. When the water environment treatment pond is fixed to the riverbed, the height of the second annular plate portion 122 of the annular component 120 is lower than the river surface, while the first annular plate portion 121 (outer higher side) and the water-blocking extension enclosure 110 are higher than the river surface. The purpose of this annular component 120 is to allow floating pollutants within the enclosed treatment space to cross the second annular plate portion 122 (inner lower side) from underwater and enter the annular groove 123, while simultaneously forming a barrier higher than the water surface on the outside of the annular groove 123, thus completing the directional collection of pollutants.

[0040] The first annular plate portion 121 is located on the outer side of the annular member 120 and is in the shape of an annular plate. The second annular plate portion 122 is located on the inner side of the annular member 120 and is also in the shape of an annular plate. Both the first annular plate portion 121 and the second annular plate portion 122 are inclined and are set at an angle. The degree of the angle can be adjusted according to actual needs to ensure that the annular groove 123 has sufficient volume to collect the floating pollutants.

[0041] The first annular plate portion 121 and the second annular plate portion 122 can be fixedly connected by processes such as welding, bolting, or integral molding, without specific limitations.

[0042] The water-blocking extension baffle 110 is fixed to the outer edge of the first annular plate portion 121. In this structure, the water-blocking extension baffle 110 acts as an outer barrier above the water surface to prevent floating pollutants that have accumulated in the annular groove 123 from overflowing from the outside.

[0043] The top of the dynamic enclosure 500 is fixedly connected to the outer wall of the second annular plate 122.

[0044] Since the bottom of the annular groove 123 is lower than the river surface, and the inner edge of the second annular plate 122 (i.e. the inner edge of the annular groove 123) is in a lower position (the inner edge of the second annular plate 122 is higher than the bottom of the annular groove 123), the insoluble substances that float to the surface of the water in the enclosed treatment space can automatically and continuously overflow from the inner edge of the second annular plate 122 into the interior of the annular groove 123, thereby achieving directional flow of pollutants.

[0045] Meanwhile, the first annular plate 121 is basically above the liquid surface or slightly above the liquid surface, together with the water-blocking extension plate 110, forming a double barrier above the water surface, ensuring that pollutants flowing into the annular groove 123 will not overflow with fluctuations.

[0046] In this optional embodiment, the top of the dynamic sealing cover 500 is fixed to the outer wall of the second annular plate portion 122, which is located at a lower inner position of the annular member 120. Therefore, the starting fixing point of the dynamic sealing cover 500 is closer to the central area of ​​the water surface float 100 and below the liquid surface. This structure allows the dynamic sealing cover 500 to extend naturally from the inner lower part of the annular member 120 to the outer lower part, making the transition path of the cover wall of the dynamic sealing cover 500 smoother, reducing structural stress concentration points, and improving the reliability of the opening and closing of the cover of the dynamic sealing cover 500. The closed treatment space formed between the dynamic sealing cover 500 and the annular member 120 has a more regular shape, which is conducive to the controllability and consistency of the pollutant floating path, and ensures the effect of "isolation and sealing" from the structural basis.

[0047] The first annular plate 121 and the second annular plate 122 are connected at an angle, and the two naturally form an annular groove 123 with sufficient volume, which can simultaneously accommodate more floating insoluble substances (flocculents and colloids) and reduce the frequency of pumping. When the aeration volume is large and the rate of floating pollutant generation is high, the annular groove 123 is not easy to overflow, and the water environment treatment pool is more robust in operation.

[0048] Because the bottom height of the annular groove 123 is specifically configured to be lower than the river surface, the floating insoluble substances encounter an "inlet" below the water surface at the inner edge of the second annular plate 122. Under the physical law that the inner and outer liquid surfaces tend to be level, the surface water carrying pollutants automatically overflows along the inner edge of the second annular plate 122 into the annular groove 123, realizing automatic, continuous, and directional collection without additional power or mechanical moving parts.

[0049] The outer boundary of the annular groove 123 is composed of two barriers: the first is the first annular plate portion 121 itself, whose inner edge can be configured to be slightly higher than the river surface, forming a preliminary barrier; the second is a water-blocking extension plate 110 fixed to the outer edge of the first annular plate portion 121, whose top is significantly higher than the river surface, forming a second, higher, and more reliable barrier. The superposition of the two barriers ensures that even under complex operating conditions such as water surface fluctuations and slight shaking of the device, pollutants collected in the annular groove 123 are unlikely to cross the outer high edge and enter the external water area, further ensuring the key technical effect of "no spillage of collected materials".

[0050] Optionally, combined Figure 1 and Figure 3 As shown, the buoyancy mechanism 200 includes a plurality of corner buoyancy boxes 210 arranged in a ring on the circumferential outer wall of the water surface floating body 100; The corner buoyancy tank 210 includes a vertical liquid section 211 and an inclined liquid section 212 arranged at an angle. The inclined liquid section 212 is fixed to the bottom of the vertical liquid section 211. The vertical liquid section 211 is fixedly connected to the water-blocking extension plate 110. The interior of the vertical liquid section 211 contains the first gas and forms a reserve buoyancy above the river surface of the riverbed. The inclined liquid section 212 is fixedly connected to the outer wall of the first annular plate 121. The interior of the inclined liquid section 212 contains the first gas and forms the main buoyancy below the river surface of the riverbed.

[0051] Specifically, the vertical liquid section 211 is the upper part of the corner buoyancy box 210, and has the shape of a box extending in a vertical or near-vertical direction. One side of the vertical liquid section 211 is fixed to the outer wall of the water-blocking extension plate 110 and fits tightly with the water-blocking extension plate 110.

[0052] The inclined liquid section 212 is the lower part of the corner buoyancy box 210, and is a box-shaped structure extending in an inclined direction. It can extend downwards towards the center of the floating body 100 on the water surface. The inclined liquid section 212 is fixed to the bottom of the vertical liquid section 211, and the internal cavities of the two can be connected or not. The other side of the inclined liquid section 212 is fixed to the corresponding outer wall of the annular member 120 (such as the outer wall of the first annular plate section 121) and fits tightly.

[0053] In this optional embodiment, the buoyancy mechanism 200 adopts a layout of multiple independent corner buoyancy boxes 210 arranged in a ring, so that the buoyancy is symmetrically distributed circumferentially on the floating body 100. When a disturbance occurs in a certain direction, the corner buoyancy box 210 in that direction generates a larger restoring torque, driving the water environment treatment pool back to a horizontal state. This ring-shaped uniform distribution design structurally ensures that the edge height of the annular groove 123 is consistent at all points, and pollutants are evenly distributed within the annular groove 123, preventing them from concentrating and overflowing due to the tilt of the water environment treatment pool, thus ensuring the technical effect of "collection without overflow".

[0054] The inclined liquid section 212 is always submerged in water, providing stable and continuous basic support; the vertical liquid section 211 is located above the water surface. When the water environment treatment tank increases in weight, it automatically draws water to generate additional buoyancy, and when the water environment treatment tank decreases in weight, it automatically floats up to restore reserves. This ensures that the water environment treatment tank maintains the correct liquid level relationship under complex working conditions such as load changes and wind and wave disturbances, thereby ensuring the continuous and reliable operation of the automatic collection function of insoluble substances.

[0055] The vertical liquid section 211 is attached to the water-blocking extension plate 110, providing buoyancy while also strengthening the rigidity of the water-blocking extension plate 110. The inclined liquid section 212 is attached to the outer wall of the annular component 120, providing primary buoyancy while enhancing the deformation resistance of the annular component 120. The inclined liquid section 212, with its inclined posture, has a much larger horizontal projected area than its vertical cross-sectional area at the same draft, significantly increasing the drainage volume and generating more sufficient primary buoyancy. This design allows the water environment treatment pond to obtain sufficient buoyancy support even in shallow water channels, expanding the applicability of the water environment treatment pond.

[0056] Optionally, combined Figures 2 to 4 As shown, the water environment treatment pond also includes a biological placement box 300, and the floating body 100 on the water surface also includes a submerged sleeve 130. The inner edge of the second annular plate portion 122 is fixedly connected to the submerged sleeve 130, and a plurality of biological placement boxes 300 are arranged in a ring at intervals on the inner wall of the submerged sleeve 130. The aeration pipe 600 passes through the interior of the submerged sleeve 130 and extends to the bottom of the dynamic closure 500.

[0057] Specifically, the submerged sleeve 130 is a component of the surface float 100, and is a tubular or cylindrical structure that runs vertically through the surface. The inner edge of the second annular plate portion 122 is fixedly connected to the submerged sleeve 130, or the inner wall of the second annular plate portion 122 of the annular member 120 extends downward to form the submerged sleeve 130. Several biological placement boxes 300 are fixedly connected to the inner wall of the submerged sleeve 130. The interior of the biological placement boxes 300 is used to place aquatic plants or agents, which participate in biological treatment after their toxicity is reduced within the closed treatment space. At the same time, the submerged sleeve 130 also provides a passage for the aeration pipe 600.

[0058] Multiple biological placement boxes 300 are evenly distributed along the inner wall of the submersible sleeve 130, with gaps between adjacent biological placement boxes 300. This layout takes several considerations into account: first, it makes full use of the circumferential space of the inner wall of the submersible sleeve 130, increasing the total capacity of the biological placement boxes 300; second, the spaced arrangement ensures that water flow can circulate between each biological placement box 300, allowing the aquatic plants or agents inside the biological placement boxes 300 to have full contact with the surrounding water; and third, each biological placement box 300 is set up independently, allowing different types of aquatic plants or agents to be placed as needed, achieving functional zoning.

[0059] The biological placement box 300 is installed on the inner wall of the submersible sleeve 130, which is located in the upper part of the river below the liquid surface. This location has better dissolved oxygen conditions and lower concentrations of toxic substances compared to the bottom sediment of the riverbed, which is more conducive to the survival of benthic organisms such as snails and aquatic plants.

[0060] The interior of the biological enclosure 300 can be filled with aquatic plants or chemicals, specifically including: Aquatic plants: such as calamus, water hyacinth, and duckweed, are aquatic plants with water purification functions. These plants absorb nutrients such as nitrogen and phosphorus, as well as some organic matter, from the water through their roots, and can further degrade pollutants through the microbial film attached to their roots.

[0061] Chemicals: These include biological and chemical agents. Biological agents, such as microbial agents (photosynthetic bacteria, nitrifying bacteria, etc.), can accelerate the decomposition and transformation of organic matter; chemical agents, such as flocculants, heavy metal chelators, and pH adjusters, are used to assist in the removal of specific pollutants. Chemicals can be directly added to the biological treatment tank 300, allowing for slow, localized release and continuous action on the water within the enclosed treatment space.

[0062] The aeration pipe 600 enters the upper port of the submerged sleeve 130 from inside the water-blocking extension plate 110, runs vertically downward along the inner cavity of the submerged sleeve 130, passes through the lower port of the submerged sleeve 130, and continues to extend to the riverbed soft mud layer at the bottom of the dynamic sealing cover 500.

[0063] In this optional embodiment, the submerged sleeve 130 is located in the upper-middle part of the river, with its bottom opening communicating with the enclosed treatment space, but its position is relatively far from the black and odorous sediment layer of the riverbed. The biological placement box 300 is installed on the inner wall of the submerged sleeve 130. The aquatic plants and chemicals inside the biological placement box 300 are located in the upper-middle layer of the water, where the toxicity concentration is much lower than that of the riverbed surface. Simultaneously, the tubular structure of the submerged sleeve 130 provides the biological placement box 300 with a relatively independent microenvironment less affected by external disturbances.

[0064] The aeration pipe 600 reaches the bottom of the dynamic enclosure 500, specifically the soft mud layer of the riverbed, through the internal channel of the submerged sleeve 130, where a second gas is introduced for agitation and aeration. Within the enclosed space, aeration causes insoluble substances in the bottom mud to float to the surface, are collected by the annular groove 123, and are actively extracted by the drain pipe 700. This continuous physical separation process directly removes the main sources of toxic and blackening / odorous substances in the water, resulting in a rapid and substantial reduction in toxicity within the enclosed environment of the dynamic enclosure 500. This reduction in toxicity is a prerequisite for efficient subsequent biological treatment; for example, the lower the toxicity of the water, the higher the survival rate, the more vigorous the metabolism, and the higher the purification efficiency of the aquatic organisms in the biological enclosure 300.

[0065] Multiple biological placement boxes 300 are arranged in a ring along the inner wall of the submerged sleeve 130, with the gaps between adjacent boxes forming water flow channels. Under the airlift effect of aeration and the disturbance of the water body, the water in the enclosed treatment space continuously circulates, flowing through the gaps between the biological placement boxes 300. Compared to a centralized single-box arrangement, this layout significantly increases the contact area between aquatic plants or agents and the surrounding water. The ring arrangement of the multiple biological placement boxes 300 ensures that the water can fully contact the boxes regardless of the direction from which it enters the submerged sleeve 130; the spacing provides unobstructed flow channels, preventing short-circuiting or dead zones. This design allows the biological purification process to uniformly and efficiently cover the water body throughout the entire enclosed treatment space.

[0066] Optionally, the dynamic enclosure 500 includes a flexible soft layer and a plurality of rings connected vertically in sequence, the flexible soft layer covering the outside of the rings; the flexible soft layer is made of a water-resistant material or a water-permeable material.

[0067] Specifically, the dynamic enclosure 500 is a cover-like or curtain-like structure extending downwards from the outer wall of the annular component 120 to the riverbed. Its function is to enclose and form a closed management space underwater, relatively isolated from the external open water area. In this embodiment, the dynamic enclosure 500 specifically includes two types of components: multiple rings forming a skeleton support layer, and a flexible soft layer forming a skin wrapping layer.

[0068] The ring body is a ring-shaped frame component with a certain rigidity, and its material can be corrosion-resistant materials such as stainless steel, engineering plastics, and fiberglass. Multiple ring bodies are arranged vertically in sequence, that is, arranged at intervals from top to bottom, forming the longitudinal skeleton of the dynamic enclosure 500.

[0069] The rings can be connected in the following ways: for example, the rings can be sewn or heat-sealed to the inside or outside of the flexible soft layer at intervals, and the flexible soft layer can be used to suspend and position the rings; or, adjacent rings can be connected by independent flexible connectors (such as nylon ropes or stainless steel chains), and the flexible soft layer can cover the outside of the rings and the flexible connectors; or, some rings can be directly fixed to the flexible soft layer, and other rings can be suspended by connectors, so as to balance structural stability and adaptability.

[0070] The flexible soft layer is a cover made of one or more flexible materials, which covers the outside of the ring. The specific covering method is as follows: the flexible soft layer is wrapped from the outside of the ring, so that the ring is inside the flexible soft layer or in the interlayer, and the flexible soft layer forms the continuous outer surface of the dynamic closed cover 500.

[0071] The flexible layer can be made of one of the following two materials: Waterproofing materials include PVC coated fabric, polyurethane coated fabric, and rubber waterproof fabric. These materials are completely impermeable to water, and the resulting dynamic enclosure 500 can completely isolate the water within the enclosed space from the external river water, preventing any form of hydraulic exchange.

[0072] Permeable materials: such as geotextiles, non-woven fabrics, and screens, are filter materials with a certain pore size. These materials allow water to flow through, but can trap particles larger than a specific size depending on the selected pore size. For example, using precision filter materials with a pore size of less than 5 micrometers can effectively trap colloidal and flocculent particles with a diameter of 5 to 11 micrometers generated by aeration in a closed space, while allowing clean water to pass through.

[0073] In this optional embodiment, multiple rings are arranged vertically to form a multi-point skeletal support. Compared to single-layer or double-layer structures with support rings only at the top and bottom, the multi-ring distributed support effectively reduces the unsupported span between the rings. When the soft layer at a certain span is subjected to lateral pressure from water flow, the adjacent rings above and below share the force, limiting the deformation of the flexible soft layer to a controllable range. The dynamic enclosure 500 maintains a round and stable longitudinal shape as a whole. This stable longitudinal structure of the dynamic enclosure 500 is a fundamental guarantee for the integrity of the boundary of the closed treatment space, strengthening the physical blocking effect on pollutant diffusion from the perspective of structural reliability.

[0074] The ring body provides rigid support, while the flexible layer provides sealing or filtration. The ring body "expands" the flexible layer into the required shape to ensure the internal space volume of the enclosure; the flexible layer "wraps" the ring body into a continuous surface to ensure the integrity of the seal. The structural design avoids the dilemma of a single material having to "both support and seal," enabling the Dynamic Enclosure 500 to maintain stable isolation performance even under long-term immersion and water flow impact conditions, providing a continuous and reliable sealing boundary for remediation operations.

[0075] Optionally, the water environment treatment pond also includes a counterweight structure, which is fixedly connected to the bottom of the dynamic enclosure 500. The counterweight structure is used to drive the bottom of the dynamic enclosure 500 into the soft soil of the riverbed under the action of gravity.

[0076] Specifically, the counterweight structure is a weighted component fixed to the bottom of the dynamic enclosure 500. Its core function is to provide sufficient gravity load to drive the bottom of the dynamic enclosure 500 to sink downward and insert into the soft mud layer on the riverbed surface.

[0077] The materials for the counterweight structure can be high-density and corrosion-resistant, including but not limited to: metal materials, such as cast iron, stainless steel, lead blocks, etc., which have the advantages of high density and high weight per unit volume, and can provide sufficient gravity in a small volume; concrete or stone, which are inexpensive, readily available, and suitable for large-area deployment; and filled counterweight bags, which are made of wear-resistant fabric and filled with heavy materials such as sand, gravel, and iron sand, which can be filled on-site, facilitating transportation and weight adjustment.

[0078] The counterweight structure and the bottom of the dynamic enclosure 500 can be fixedly connected in the following way: Directly fixed to the bottom edge of the flexible layer: The counterweight structure is sewn, riveted or clamped to the bottom edge of the flexible layer so that the weight of the counterweight structure acts directly on the bottom edge of the layer. Fixed to the bottommost ring: The counterweight structure is fixed to the bottommost ring of the dynamic enclosure 500 by welding, bolting or binding, so that the gravity is evenly transferred to the bottom edge of the flexible soft layer through the ring. Segmented counterweight: The counterweight structure includes multiple counterweight blocks, which are spaced out circumferentially along the bottom of the dynamic enclosure 500 to form a segmented counterweight layout. This layout allows each segment of the counterweight to function independently according to local changes in the riverbed topography, further enhancing the bottom adhesion effect.

[0079] The counterweight structure operates based on the principle of gravity settling: when the floating body 100 is positioned by the fixed piles 140 and the dynamic enclosure 500 is driven downward by the upward movement of the buoyancy mechanism 200, the counterweight structure generates a downward tension under its own weight. This tension is transmitted longitudinally (from bottom to top) along the dynamic enclosure 500, keeping the entire dynamic enclosure 500 in a taut or semi-taut state. The gravity load of the counterweight structure must be greater than the sum of the buoyancy of the flexible soft layer in the water and the initial penetration resistance of the soft soil at the bottom of the riverbed, thereby ensuring that the bottom of the dynamic enclosure 500 can overcome buoyancy and squeeze out the surface soft mud, inserting into the soft soil of the riverbed to a certain depth.

[0080] In this optional embodiment, the counterweight structure is fixedly connected to the bottom of the dynamic enclosure 500, applying a concentrated downward gravity load to the bottom of the dynamic enclosure 500, actively overcoming the buoyancy of the dynamic enclosure 500 in water, and forcing the bottom to continue to sink until it contacts and enters the soft soil of the riverbed.

[0081] The bottom of the Dynamic Enclosure 500 is not simply placed flat on the riverbed, but inserted into it, forming a vertical isolation boundary that penetrates deep into the soft soil.

[0082] The counterweight structure always acts on the bottom of the dynamic enclosure 500, forming a continuous downward preload, which keeps the dynamic enclosure 500 under a certain tension in the longitudinal direction. When the rising bubbles generated by aeration impact the enclosure wall from the inside, the tensioned dynamic enclosure 500 has better resistance to disturbance, and the bottom end is not easily lifted, thus continuously and stably maintaining the integrity of the closed boundary throughout the entire treatment cycle.

[0083] The counterweight structure and the flexible layer work synergistically: the counterweight structure provides gravity, while the flexible layer provides deformation capability. When the bottom encounters a local protrusion, the flexible layer undergoes local elastic or plastic deformation under the gravity of the counterweight structure, covering the protruding area; when the bottom crosses a depression, the counterweight structure can partially sink into the depression to prevent it from being suspended. The combination of the two forms a flexible sealing line at the bottom of the dynamic enclosure 500 that can adaptively deform with the riverbed topography, maximally bridging the irregular gaps between the bottom of the dynamic enclosure 500 and the riverbed, and minimizing the bottom leakage channels.

[0084] Optionally, combined Figures 2 to 4As shown, the floating body 100 also includes multiple fixed piles 140 and multiple guide rings 150. The inner edge of the second annular plate 122 is provided with multiple positioning holes 1221 arranged in a ring. The multiple guide rings 150 are installed in a ring at intervals on the outer wall of the submerged sleeve 130. The fixed piles 140 pass through the positioning holes 1221 and the guide rings 150 and are inserted into the soft soil of the riverbed. After the fixed piles 140 are removed, the floating body 100 floats up under the action of the buoyancy mechanism 200 and drives the dynamic sealing cover 500 to detach from the soft soil of the riverbed.

[0085] Specifically, the anchoring pile 140 is a slender pile-shaped component used to penetrate the water from the floating body 100 downwards and eventually drive into the soft soil or bottom mud layer of the riverbed, anchoring the floating body 100 at a specific location in the target water area.

[0086] The materials for the 140 fixed piles can be: metal materials, such as steel pipes and I-beams, which have high strength and bending resistance, and are suitable for rivers with greater water depth or harder bottoms; wood materials, such as anti-corrosion treated wooden piles, which are inexpensive and suitable for temporary anchoring in shallow water and soft mud bottoms; and composite materials, such as fiberglass piles, which have both corrosion resistance and certain strength, and are suitable for highly corrosive water bodies.

[0087] The length of the fixed pile 140 must meet the vertical distance from the operating platform 400 or the floating body 100 (ring part 120) to the riverbed, and allow sufficient embedment depth to ensure anchoring force.

[0088] The inner edge of the second annular plate 122 is the circumferential edge of the inner side of the annular member 120, near the central submerged sleeve 130. The positioning hole 1221 is set in this position so that each fixing pile 140 passes through the corresponding positioning hole 1221, and the force is balanced.

[0089] Multiple positioning holes 1221 are evenly distributed circumferentially. The positioning holes 1221 provide a channel for the fixing post 140 to pass through the annular member 120, while constraining the horizontal position of the fixing post 140, so that the fixing post 140 remains fixed in the horizontal direction relative to the annular member 120.

[0090] Guide rings 150 are installed on the outer wall of the submersible sleeve 130. The position of each guide ring 150 is aligned vertically with a positioning hole 1221, forming a vertical channel from top to bottom. The number of guide rings 150 matches the number of positioning holes 1221, forming a one-to-one corresponding guide channel group.

[0091] Multiple guide rings 150 can be set vertically for each fixed pile 140 (for example, multiple guide rings 150 can be set at different heights of the submerged sleeve 130) to increase guiding accuracy and longitudinal constraint range. The fixed pile 140 passes through the positioning hole 1221 on the inner edge of the second annular plate 122 from top to bottom, and then continues downward, passing through the guide ring 150 at the corresponding position on the outer wall of the submerged sleeve 130, and finally driving into the soft soil of the riverbed.

[0092] The installation and removal of the fixed pile 140 can be carried out in the following ways: Installation: The fixed pile 140 is vertically lowered from above the operating platform 400 using hoisting equipment. Guided by the positioning hole 1221 and the guide ring 150, the pile automatically aligns with the riverbed and embeds itself into the riverbed under its own weight or the action of an external pile hammer. Removal: When the treatment work is completed and the location needs to be changed, the operator pulls the fixed pile 140 upward from the operating platform 400. The pulling force can be applied manually, using a winch or crane to overcome the frictional resistance and adhesion between the fixed pile 140 and the bottom mud.

[0093] In this optional embodiment, the fixed pile 140 extends from the floating body 100 on the water surface to the riverbed, reliably anchoring the water environment treatment pool in the horizontal direction, eliminating the possibility of drifting or swaying, and ensuring that the closed treatment space is always accurately located directly above the area to be treated, thus guaranteeing the targeting of the treatment operation and the continuous integrity of the closed boundary.

[0094] The positioning hole 1221 provides the first horizontal constraint (top of the fixed pile 140), and the guide ring 150 provides the second horizontal constraint (lower middle part of the fixed pile 140). The two constraints together lock the fixed pile 140 on the predetermined vertical path. This dual guiding structure ensures that the fixed pile 140 maintains a vertical posture throughout the driving process, ultimately reliably driving into the riverbed and reaching the designed anchoring depth, providing stable and durable anchoring force for the water environment remediation pond.

[0095] After the fixed pile 140 is removed, the buoyancy mechanism 200 drives the entire floating body 100, along with the dynamic enclosure 500, to rise to the surface. The dynamic enclosure 500 rises together with the annular component 120, and its bottom end detaches vertically from the soft mud layer, rather than being dragged laterally. This overall detachment method protects the structural integrity of the dynamic enclosure 500, prevents the flexible soft layer from being scratched and damaged on the riverbed, and extends the service life of the dynamic enclosure 500. At the same time, after overall detachment, the water environment treatment pond can be directly towed to the next treatment point by the tow rope 800, which is efficient and low-risk.

[0096] Optionally, combined Figure 4As shown, the water environment treatment pool also includes a traction rope 800. The bottom end of the traction rope 800 is fixedly connected to the bottom of the dynamic enclosure 500, and the top end of the traction rope 800 extends above the floating body 100 on the water surface. When the floating body 100 on the water surface moves, the dynamic enclosure 500 is folded and stored by winding the traction rope 800.

[0097] Specifically, the traction rope 800 is a slender, flexible strip-shaped component used to connect the bottom of the dynamic enclosure 500 to the top of the floating body 100 on the water surface, transmitting the winding tension.

[0098] The materials available for the traction rope 800 include: synthetic fiber ropes such as nylon rope, polyester rope, and ultra-high molecular weight polyethylene rope, which are lightweight, corrosion-resistant, and high-strength, and are commonly used rigging materials in aquatic engineering; metal rigging such as stainless steel wire rope, which has higher strength and better wear resistance, and is suitable for situations with greater water depth or heavier covers that require greater winding force; and composite ropes such as plastic-coated steel wire rope, which has a steel wire core and an outer plastic sheath, combining strength and corrosion resistance.

[0099] The length of the traction rope 800 must meet the following requirements: when the dynamic enclosure 500 is fully deployed and its bottom end is submerged in the riverbed, the traction rope 800 extends from the bottom of the enclosure to above the floating body 100 on the water surface, with sufficient redundancy for operators or winding equipment to grasp and wind.

[0100] The bottom end of the traction rope 800 can be connected to the bottom of the dynamic enclosure 500 in the following ways: for example, the bottom end of the traction rope 800 can be tied or fastened to the counterweight structure at the bottom of the dynamic enclosure 500, using the counterweight structure as the connection anchor point of the traction rope 800; or, the bottom end of the traction rope 800 can be fixed to the lowest edge of the flexible layer by sewing, rivets or clamps; or, the bottom end of the traction rope 800 can be connected to a ring at the bottom of the dynamic enclosure 500, so that the winding tension can be evenly transmitted to the bottom circumference of the entire dynamic enclosure 500 through the ring.

[0101] To ensure even force distribution, multiple traction ropes 800 (such as 2 to 4 symmetrically arranged) can be evenly arranged around the bottom of the dynamic enclosure 500. They can be operated synchronously during winding to lift the bottom of the dynamic enclosure 500 evenly, thus avoiding twisting or tilting of the dynamic enclosure 500 due to force on one side.

[0102] Once the fixed pile 140 is completely removed: the floating body 100 is no longer constrained downwards by the fixed pile 140, and the total weight of the water environment treatment pool decreases; the buoyancy of the buoyancy mechanism 200 (especially the main buoyancy generated by the inclined liquid section 212 and the reserve buoyancy generated by the vertical liquid section 211) is greater than the current total weight of the water environment treatment pool, generating an upward net buoyancy; this net buoyancy drives the floating body 100 to float upwards as a whole, and the liquid level of the annular component 120 rises; as the annular component 120 floats upwards, through its fixed connection with the top of the dynamic enclosure 500, it drives the entire dynamic enclosure 500 to move upwards, and the bottom of the dynamic enclosure 500 detaches from the soft soil of the riverbed, returning to a movable, freely floating state. Afterwards, the dynamic enclosure 500 can be towed to the next target water area with the assistance of the towing rope 800, or retrieved to the shore for maintenance.

[0103] The folding and storage process of the dynamic enclosure 500: After the towing rope 800 is wound to a predetermined length, the dynamic enclosure 500 enters the folding and storage state. Specifically, the bottom of the dynamic enclosure 500 is pulled upwards to a position close to the annular component 120, significantly shortening its longitudinal length; the flexible soft layer wrinkles or overlaps between the rings, reducing the distance between adjacent rings, and multiple rings tend to overlap and converge; the overall volume of the dynamic enclosure 500 is significantly reduced underwater, and the maximum horizontal cross-section also decreases due to the enclosure's folding; the overall underwater profile of the water environment treatment pool is more compact, with changes in draft, facilitating towing or hoisting. In the folded and storage state, the dynamic enclosure 500 is no longer in contact with the riverbed, and its bottom returns to a free state, allowing it to be towed to the shore or by auxiliary vessels using the towing rope 800.

[0104] The traction rope 800 can be wound manually or electrically. Manual winding involves the operator pulling the traction rope 800 directly from the operating platform 400, manually lifting the bottom of the dynamic enclosure 500 upwards. Electric winding involves installing a small winch or electric winch on the operating platform 400, winding the top of the traction rope 800 onto the winch drum, and driving the winding with a motor. This method provides greater winding force and is suitable for deep-water conditions.

[0105] In this optional embodiment, by winding up the towing rope 800, the longitudinal length of the dynamic enclosure 500 is significantly shortened. As the dynamic enclosure 500 folds and retracts, the underwater surface area facing the current decreases dramatically, and the towing resistance drops significantly. This allows the water environment remediation pond to be safely and quickly towed to the next remediation site. Folding and retracting the dynamic enclosure 500 using the towing rope 800 minimizes its length below the water surface, keeps its bottom away from riverbed obstacles, and, protected by the ring body and its own layered structure, effectively prevents scratches and snagging damage during towing, extending the service life of the dynamic enclosure 500.

[0106] The top of the traction rope 800 extends above the operating platform 400, allowing operators to perform winding and releasing operations on the platform without entering the water. Once the water environment remediation pool reaches the new treatment location and is anchored, simply releasing the traction rope 800 will allow the dynamic enclosure 500 to automatically unfold and settle into place under the weight of the counterweight structure. After treatment is completed, removing the fixing pile 140 and winding the traction rope 800 allows the dynamic enclosure 500 to be stored, ready for relocation. The entire switching process can be completed above the water surface, ensuring safe and convenient operation without interrupting the treatment workflow.

[0107] Optionally, combined Figure 1 and Figure 4 As shown, the water environment treatment pool also includes an operating platform 400, which is detachably installed on the top of the floating body 100.

[0108] Specifically, the operating platform 400 is a horizontal working surface structure installed on top of the floating body 100 on the water surface, providing a support platform for operators, equipment and materials.

[0109] The operating platform 400 can be a perforated plate platform: made of materials such as steel plate, aluminum alloy plate, or fiberglass plate, with mesh or grating on the surface. The mesh structure ensures the load-bearing strength of the operating platform 400 while reducing its weight. At the same time, the mesh allows rainwater and splashes to drain away in time, preventing personnel from slipping due to water accumulation on the surface of the operating platform 400. The mesh can also serve as an observation window, allowing operators to directly observe the accumulation of pollutants in the annular groove 123 below, facilitating the determination of when to pump out pollutants.

[0110] The operating platform 400 is installed on top of the floating body 100, specifically on the top of the water-blocking extension panel 110. The operating platform 400 and the top of the water-blocking extension panel 110 can be fixed by bolt connection, snap-fit ​​or clamp connection, pin connection, or overlapping connection method (e.g., protrusion, slot method).

[0111] In this optional embodiment, the operating platform 400 is installed on top of the floating body 100, providing operators with a fixed working surface that is spacious, reliably supported, and slip-resistant. Operators can stand on the operating platform 400 and complete all actions directly at the treatment point, truly incorporating the "human" factor into the black mud treatment system of the riverbed, ensuring the feasibility and timely response of various precision operations.

[0112] The operating platform 400 is located directly on top of the floating body 100 on the water surface. Operators can set up a small hoisting frame on the operating platform 400 or work manually to vertically insert the fixed pile 140 into the positioning hole 1221 and the guide ring 150 and drive it into the riverbed. When removing it, the same vertical force is applied, which can greatly improve the pile driving accuracy and efficiency, reduce the dependence on auxiliary vessels, reduce operating costs, and make precise anchoring operations convenient to be carried out in the field.

[0113] Several operating interfaces can be integrated onto an operating platform 400: for example, the control end of the aeration device can be located on the operating platform 400, and the aeration pipe 600 can be laid downwards from the mesh opening of the operating platform 400; the top of the traction rope 800 can be gathered at a winch or coil on the operating platform 400; the chemical dosing port is located directly above the submersible sleeve 130 in the center of the operating platform 400, allowing operators to directly add chemicals from the operating platform 400. This integrated control center allows various functions to work together, enabling a single operator to manage multiple processes, significantly improving the efficiency and response speed of the treatment operation.

[0114] The present invention provides a method for using a water environment treatment pond, based on the water environment treatment pond described in the above embodiment, including the following steps: S100: Place the floating body 100 in the target area of ​​the riverbed, and provide buoyancy to the floating body 100 through the buoyancy mechanism 200. The target area refers to the water area in the riverbed where black mud needs to be treated.

[0115] Specifically, when the water environment treatment pond reaches the target area, the floating body 100 can be placed in the target water area by boat or hoisting, and the floating body 100 can be tied to the shore by the towing rope 800. The buoyancy mechanism 200 provides buoyancy for the floating body 100. The inclined liquid part 212 is completely submerged below the river liquid surface of the riverbed to generate buoyancy, and the vertical liquid part 211 is located above the river liquid surface as a reserve buoyancy. An operating platform 400 is installed above the floating body 100 to form an operating surface.

[0116] S200, the dynamic enclosure 500 extends downward and settles onto the soft soil of the riverbed, forming a closed treatment space.

[0117] Specifically, the fixed pile 140 can be placed on the operating platform 400 by hoisting, increasing the weight above the floating body 100. The vertical liquid section 211 provides buoyancy supplement to the floating body 100 as a reserve buoyancy. The fixed pile 140 passes sequentially through the positioning insertion hole 1221 of the second annular plate section 122 and the guide ring 150 on the circumferential outer wall of the submerged sleeve 130, and moves downward to embed itself into the soft soil of the riverbed. The weight above the floating body 100 decreases, the vertical liquid section 211 floats up, driving the dynamic sealing cover 500 to extend downward. The bottom of the dynamic sealing cover 500 descends under the influence of the weight of the counterweight structure and sinks into the soft soil above the riverbed. During this process, the dynamic sealing cover 500 will perform an axial expansion action. One end of the aeration pipe 600 passes sequentially through the operating platform 400, the water-blocking extension plate 110, the annular part 120, and the submerged sleeve 130 and extends to the bottom of the dynamic sealing cover 500.

[0118] S300, a second gas is blown into the bottom of the closed treatment space through the aeration pipe 600, causing the insoluble substances generated in the soft soil to float up, pass through the interior of the dynamic closed cover 500, and be collected into the annular groove 123 of the annular part 120 of the water surface float 100.

[0119] Specifically, the external aeration device can generate a second gas, and the aeration pipe 600 can guide the second gas to the bottom of the closed treatment space. The second gas is blown towards the black mud in the soft soil of the riverbed. The insoluble substances generated by the aeration float to the surface. Since the bottom height of the annular groove 123 of the annular component 120 is lower than the river liquid level, the generated floating insoluble substances rise and enter the annular groove 123 of the annular component 120.

[0120] S400, the insoluble substances in the annular groove 123 are discharged through the drain pipe 700.

[0121] Specifically, since the drainage pipe 700 is connected to the annular groove 123, insoluble substances can be discharged through the drainage pipe 700. At the same time, the biological placement box 300 on the inner wall of the submerged sleeve 130 is used in combination with the riverbed oxygenation and aeration method to treat the local area of ​​the dynamic closed cover 500.

[0122] If the treatment effect in step S300 is not obvious, the operator can inject auxiliary agents from the operating platform 400 into the submerged platform or the interior of the dynamic enclosure 500 to treat the enclosed treatment space of the dynamic enclosure 500. During the treatment and commissioning process, the dynamic enclosure 500 can reduce the impact on other areas outside the target area.

[0123] The method of using the water environment remediation pool also includes step S500. After the target area is treated, the operator on the operating platform 400 removes the fixing pile 140. As the fixing pile 140 leaves the riverbed, the liquid level of the river increases, and the fixing pile 140 is gradually pulled out. The pressure of the fixing pile 140 on the floating body 100 on the water surface increases, causing the vertical liquid section 211 to gradually absorb water. When the fixing pile 140 is completely removed, since the bottom end of the traction rope 800 is fixedly connected to the bottom of the dynamic enclosure 500, the operator can apply tension to the traction rope 800 manually or electrically, and pull the dynamic enclosure 500 upward by traction, so that the dynamic enclosure 500 is in a folded and retracted state for easy movement. Finally, the floating body 100 on the water surface can be transported to the next target area for treatment by other means, such as hoisting or towing.

[0124] The method of using the water environment treatment pond in this embodiment has the same beneficial effects as the water environment treatment pond described above compared to the prior art, and will not be repeated here.

[0125] While the present invention has been disclosed above, its scope of protection is not limited thereto. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention, and all such changes and modifications will fall within the scope of protection of the present invention.
