Description

Technical Field

[0001] The present invention relates to the field of ecological management, and in particular to an underwater ecological management system based on urban landscape. Background Art

[0002] As urbanization accelerates, water demand increases, but pollution leads to a decline in water quality, affecting the effective supply of water resources. More than 30% of urban groundwater is polluted, and water pollution and environmental damage have become major obstacles to urban development.

[0003] At present, the technology of constructing water ecosystem mainly carries out water ecological restoration from the perspectives of establishing ecological floating beds, improving river bottom quality, establishing ecological buffer zones, and constructing artificial wetlands. Microporous aeration and oxygenation technology is a new aeration technology that can effectively increase the oxygen content of river water, promote the decomposition of organic matter, and provide oxygen and nutrients for microorganisms, thereby helping to decompose pollutants in the water and improve the river ecosystem.

[0004] However, during the urban sewage treatment process, the water ecosystem is prone to blockage, affecting the sewage treatment effect. During long-term use, it is necessary to regularly replace the microbial sewage treatment device to ensure the sewage treatment effect.

[0005] In the existing technology, anti-blocking is carried out through operations such as flushing and moving to dredge, but the operation is cumbersome and has high requirements on the device. Urban sewage usually contains large garbage or some floating objects. For this kind of garbage, it is not possible to effectively separate it from the microbial sewage treatment device, so it cannot effectively improve the sewage treatment effect when used. Summary of the invention

[0006] One purpose of the present invention is to provide an underwater ecological management system based on urban landscape, by arranging a plurality of sewage treatment discs in a cylindrical area composed of a plurality of filter barrels, so that the filter barrels perform a first filtration on the sewage, thereby preventing garbage from entering the cylindrical area composed of the plurality of filter barrels and causing blockage of the water treatment discs.

[0007] This purpose is achieved by adopting the following technical solutions:

[0008] An underwater ecological management system based on urban landscape includes a suspended board for planting plants, and a plurality of sewage treatment discs are connected below the suspended board.

[0009] The wastewater treatment disc is loaded with microorganisms, which convert organic matter in domestic sewage into harmless substances such as carbon dioxide and water by fixing free microorganisms on specific carriers. At the same time, microorganisms can also help eliminate harmful substances in sewage, such as heavy metals and organic pollutants.

[0010] The suspended board is used to control the position of the sewage treatment disc. The suspended board floats on the water surface. The plants on the suspended board are not only beneficial to sewage treatment, but also to urban landscape.

[0011] The sewage treatment discs are all circular and arranged in sequence from top to bottom. The sides of the sewage treatment discs are connected to a plurality of filter barrels. The filter barrels are tangent to the sides of the sewage treatment discs, and two adjacent filter barrels are tangent to each other. The sewage treatment discs are located in a cylindrical area formed by the filter barrels.

[0012] The interior of the filter barrel is a cavity, and the outer side of the filter barrel is provided with a plurality of water outlet holes connected with the internal cavity. When there is garbage matter, the filter barrel can isolate the larger garbage matter outside, and the water enters the interior of the filter barrel through the water outlet holes, and enters the cylindrical area composed of several filter barrels from the interior of the filter barrel, and then the water comes into contact with the microorganisms on the sewage treatment disk, and the microorganisms on the sewage treatment disk carry out sewage treatment.

[0013] This system can solve the problem of garbage blocking the sewage treatment plate from the root, and this system has no complicated structure and does not require additional operations, and can better achieve the treatment effect of the microorganisms on the sewage treatment plate on the sewage.

[0014] The filter barrel performs the first filtration on the sewage to prevent garbage from entering the cylindrical area composed of several filter barrels, causing blockage in the sewage treatment disk, and thus affecting the treatment effect of microorganisms on sewage.

[0015] Furthermore, in order to further improve the effect of underwater ecological management, the filter barrel can not only filter the sewage for the first time, but also further recycle sewage garbage. Specifically:

[0016] A separation barrel is arranged inside the filter barrel, and the upper end of the separation barrel is detachably connected to the upper end of the filter barrel. The separation barrel is used to separate garbage so that the garbage is located in the separation barrel.

[0017] The suspension plate has the same shape and size as the sewage treatment disc, and the upper end of the filter barrel is open; the upper ends of several filter barrels are connected to the side of the suspension plate, and the upper ends of several filter barrels are provided with water inlet components, which are used to allow water to enter the filter barrel through the upper end of the filter barrel.

[0018] When in use, the water inlet assembly opens the opening at the upper end of the filter barrel, and the sewage brings the garbage into the separation barrel inside the filter barrel. The sewage and garbage are separated in the separation barrel, and the garbage remains in the separation barrel. The sewage passes through the separation barrel and enters between the filter barrel and the separation barrel, and flows out through the water outlet on the filter barrel. A part of the sewage flows into the cylindrical area and contacts the sewage treatment disk, and the sewage treatment disk treats the sewage.

[0019] After a certain period of use, the separation barrel in the filter barrel can be taken out by the staff, the garbage in the separation barrel can be cleaned, and then the separation barrel can be connected to the filter barrel again to achieve filtering and separation again.

[0020] Furthermore, a one-way plate is provided on the water outlet, and the one-way plate allows the sewage in the filter barrel to flow out. Therefore, the sewage cannot enter the filter barrel through the water outlet, and can only be discharged through the filter barrel and the water outlet.

[0021] At the same time, a first pressing plate is arranged in the separation barrel, a second pressing plate is arranged between the filter barrel and the separation barrel, a first telescopic rod is arranged on the first pressing plate, and a second telescopic rod is arranged on the second pressing plate. The first telescopic rod and the second telescopic rod are telescoped to drive the first pressing plate and the second pressing plate to move up and down.

[0022] When in use, the first telescopic rod and the second telescopic rod are adjusted to drive the first pressing plate and the second pressing plate to move up and down, so as to squeeze the sewage and garbage in the filter barrel and the separation barrel, and force the sewage to be discharged from the water outlet. Under the action of external force, the sewage can be better discharged from the water outlet, and the water flow speed is increased during the discharge process. A part of the sewage impacts the sewage treatment disk in the cylindrical area, which increases the water flow speed and improves the effect of the microorganisms on the sewage treatment disk on sewage treatment.

[0023] Among them, the water inlet assembly can be of various structures, as long as it can realize the opening at the upper end of the filter barrel to be opened or closed. The water inlet assembly includes a telescopic rod arranged at the upper end of the filter barrel, and the upper end of the telescopic rod is connected to a baffle, and the telescopic rod drives the baffle to extend and retract to open or close the opening at the upper end of the filter barrel. When the telescopic rod is extended, the baffle is located above the upper end of the filter barrel, and the sewage can enter the filter barrel through the area between the baffle and the upper end of the filter barrel. When the telescopic rod is shortened, the baffle is located on the upper end of the filter barrel, and the baffle and the filter barrel are in contact with each other, and the sewage cannot enter the filter barrel through the upper end of the filter barrel.

[0024] Preferably, a transparent layer is provided on the outside of the water outlet, and an optical fiber is provided in the transparent layer. The role of the optical fiber in sewage treatment is mainly to decompose pollutants through photocatalysis. At the same time, the optical fiber can also act on the microorganisms on the sewage treatment disk to promote the treatment of sewage by microorganisms.

[0025] At the same time, an aeration tube is wrapped around the filter barrel. The aeration tube aerates the water, which can increase the oxidation rate. Microorganisms need to consume oxygen to degrade organic matter. Aeration increases the dissolved oxygen content in the water, thereby accelerating the oxidation and decomposition process of organic matter by microorganisms. In addition, aeration fully mixes the organic matter and other suspended matter in the wastewater through stirring, so that they are evenly distributed in the water, which helps to increase the contact opportunities between microorganisms and organic matter and accelerate the degradation process. In the sewage treatment process, aeration can effectively remove harmful gases such as hydrogen sulfide and carbon dioxide, thereby improving water quality. Secondly, aeration stirs the water body, so that suspended matter and microorganisms remain suspended in the water, avoid precipitation, and keep the water clear. Aeration increases the dissolved oxygen content in the water, improves the self-purification ability of the water body, and is conducive to improving the water environment.

[0026] Preferably, filter plates are provided at the lower ends of the plurality of filter barrels, and the plurality of sewage treatment discs are located in a cylindrical region composed of the plurality of filter barrels, filter plates and suspension plates. This prevents sewage and garbage from entering the cylindrical region composed of the dry filter barrels, filter plates and suspension plates from below the sewage treatment discs, and prevents garbage from accumulating in the cylindrical region, which would affect the treatment of sewage by microorganisms.

[0027] Furthermore, the upper opening of the filter barrel is located below the water surface. In the natural environment, water automatically flows down because of gravity. For example, river water flows from upstream to downstream because water flows to lower places. When the upper opening of the filter barrel is opened, the water automatically flows into the filter barrel under the action of gravity and is filtered for the first time through the filter barrel.

[0028] Compared with the prior art, the present invention has the following advantages and beneficial effects:

[0029] The invention discloses an underwater ecological management system based on urban landscape. The invention can arrange a plurality of sewage treatment discs in a cylindrical area composed of a plurality of filter barrels so that the filter barrels filter the sewage for the first time, thereby preventing garbage from entering the cylindrical area composed of the plurality of filter barrels and clogging the water treatment discs.

[0030] Moreover, the system does not require additional operation and adjustment, and filters directly through the filter barrel. At the same time, a separation barrel is provided in the filter barrel, and the sewage and garbage are recycled into the separation barrel. The sewage and garbage can be directly recycled and separated by taking the separation barrel out of the filter barrel, thereby improving the sewage treatment efficiency.

DETAILED DESCRIPTION

[0045] In order to make the objectives, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with embodiments and drawings. The exemplary embodiments of the present invention and their description are only used to explain the present invention and are not intended to limit the present invention.

[0046] In the description of the present invention, it should be understood that the terms "front", "rear", "left", "right", "up", "down", "vertical", "horizontal", "high", "low", "inside", "outside", etc., indicating directions or positional relationships are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as limiting the scope of protection of the present invention.

[0047] Example 1

[0048] like Figure 1 and Figure 2 As shown, it includes a suspended plate 1 for planting plants, and a plurality of sewage treatment discs 3 are connected below the suspended plate 1. The plurality of sewage treatment discs 3 are all circular and arranged in sequence from top to bottom. The sides of the plurality of sewage treatment discs 3 are connected to a plurality of filter barrels 2, and the plurality of filter barrels 2 are tangent to the sides of the sewage treatment disc 3, and two adjacent filter barrels 2 are tangent; the plurality of sewage treatment discs 3 are located in a cylindrical area formed by the plurality of filter barrels 2.

[0049] The interior of the filter barrel 2 is a cavity, and the outer side of the filter barrel 2 is provided with a plurality of water outlet holes 14 connected with the internal cavity. The filter barrel 2 is used for filtering sewage for the first time to prevent garbage from entering the cylindrical area formed by the plurality of filter barrels 2.

[0050] During use, when the system is located in sewage, the suspension board 1 allows the system to float on the water surface and will not be completely submerged in the water. Several sewage treatment discs 3 below the suspension board 1 are located underwater, and sewage garbage is isolated outside the filter barrel 2. Therefore, the system fundamentally avoids the contact between sewage garbage and the sewage treatment disc 3, avoids the clogging of the sewage treatment disc by sewage garbage, and reduces the frequency of operators regularly cleaning the sewage treatment disc. At the same time, when larger garbage clogs the sewage treatment disc 3, the existing system cannot effectively separate the larger garbage from the sewage treatment disc through telescopic insertion, and long-term use will affect the sewage treatment efficiency of the sewage treatment disc. The present system directly prevents sewage garbage from entering the sewage treatment disc, and does not require additional operations, which is more conducive to long-term use.

[0051] In some embodiments, filter plates are provided at the lower ends of the plurality of filter barrels 2, and the plurality of sewage treatment discs 3 are located in a cylindrical region formed by the plurality of filter barrels 2, the filter plates and the suspension plate 1. Such a configuration can further prevent sewage and garbage from entering the sewage treatment disc 3 from the lower end of the cylindrical region. The filter plates prevent garbage from entering the cylindrical region, while sewage can enter the cylindrical region through the filter plates and contact the sewage treatment disc, and the microorganisms on the sewage treatment disc treat the sewage.

[0052] In some embodiments, the system may include a plurality of suspension boards 1, and the size of the suspension boards 1 is adjusted according to actual conditions. The suspension boards 1 are circular.

[0053] Example 2

[0054] On the basis of the above embodiment, the suspension board 1 is connected with a first connecting rod 4, such as Figure 3 As shown, the first connecting rod 4 is vertically arranged, and a plurality of sewage treatment discs 3 are connected to the lower part of the suspension plate 1. The plurality of sewage treatment discs 3 are all circular and arranged in sequence from top to bottom. The plurality of sewage treatment discs 3 are located in a cylindrical area formed by a plurality of filter barrels 2.

[0055] The first connecting rod 4 is connected to the sewage treatment disc via a second connecting rod 5, and a loading net for loading microorganisms is arranged on the sewage treatment disc.

[0056] In some embodiments, the suspension plate 1 and the sewage treatment plate 3 have the same shape and size, and the upper end of the filter barrel 2 is open; the upper ends of several filter barrels 2 are connected to the side of the suspension plate 1, and the upper ends of several filter barrels 2 are provided with water inlet components, which are used to allow water to enter the filter barrel 2 through the upper end of the filter barrel 2.

[0057] The water inlet assembly can be of various structures, as long as it can achieve the effect of opening or closing the opening at the upper end of the filter barrel 2. The water inlet assembly can be a telescopic plate arranged at the upper end of the filter barrel, and the telescopic plate is telescopic to open or close the opening at the upper end of the filter barrel.

[0058] In some embodiments, Figure 4 As shown, the water inlet assembly includes a telescopic rod 7 arranged at the upper end of the filter barrel 2, and the upper end of the telescopic rod 7 is connected to a baffle 6. The telescopic rod 7 drives the baffle 6 to extend and retract to open or close the opening at the upper end of the filter barrel 2.

[0059] When the telescopic rod 7 is extended, driving the baffle 6 to move upward, the opening at the upper end of the filter barrel 2 is opened, as shown in FIG. Figure 4 shown.

[0060] When the telescopic rod 7 is shortened and the baffle is driven to move downward, the opening at the upper end of the filter barrel 2 is closed. Figure 3 At this time, the baffle plate 6 is in contact with the opening at the upper end of the filter barrel 2, and the height of the baffle plate 6 is higher than the suspension plate 1. When the system is located in sewage, the baffle plate 6 is in contact with the opening at the upper end of the filter barrel 2, and the upper end of the baffle plate is above the water surface. The opening at the upper end of the filter barrel 2 is below the water surface.

[0061] When the telescopic rod 7 is extended and drives the baffle 6 to move upward, the opening at the upper end of the filter barrel 2 is opened, and the opening at the upper end of the filter barrel 2 is located below the water surface. The sewage automatically flows into the filter barrel from the opening at the upper end of the filter barrel 2 under the action of gravity. During the inflow process, the water body drives the sewage and garbage in the filter barrel 2, and the filtered sewage flows out through the water outlet on the filter barrel 2.

[0062] In some embodiments, the water outlet holes are arranged on the inner sides of the plurality of filter barrels 2, i.e., on the side where the cylindrical area formed is in contact with the sewage treatment disk 3, so that the water flowing out of the water outlet holes can directly enter the cylindrical area and act on the sewage treatment disk 3, further preventing garbage from entering the cylindrical area.

[0063] In some embodiments, the water outlet is arranged on the side of the plurality of filter barrels 2, which may be the side of the cylindrical area in contact with the sewage treatment disk 3, or the side in contact with the external water body. Figure 5 As shown, a one-way plate 16 is provided on the water outlet 14 , and the one-way plate 16 allows the sewage in the filter barrel 2 to flow out.

[0064] When the system is located underwater, due to the one-way plate on the water outlet, sewage cannot enter the filter barrel 2 from the water body and the water outlet. Figure 6 As shown, the liquid can only be discharged outward from the filter barrel and the water outlet, thereby effectively avoiding blockage of the water outlet.

[0065] In some embodiments, Figure 6 As shown, a transparent layer 15 is disposed outside the water outlet 14, and an optical fiber is disposed inside the transparent layer 15. The optical fiber acts on the microorganisms on the sewage treatment disc 3 to promote the sewage treatment effect of the microorganisms.

[0066] In some embodiments, an aeration tube is wound around the filter barrel 2. The aeration tube is used to aerate the water.

[0067] In some embodiments, the water outlet holes on the filter barrel 2 include a first water outlet hole, a second water outlet hole and a third water outlet hole at each sewage treatment disk, and the first water outlet hole, the second water outlet hole and the third water outlet hole are arranged in sequence from top to bottom, wherein the water outlet direction of the second water outlet hole is parallel to the direction of the corresponding sewage treatment disk, the first water outlet hole and the third water outlet hole are symmetrically arranged according to the second water outlet hole, the water outlet direction of the first water outlet hole is inclined downward, and the water outlet direction of the third water outlet hole is inclined upward, and the angle between the water outlet direction of the first water outlet hole, the third water outlet hole and the second water outlet hole is 60 degrees.

[0068] When water flows out of the first water outlet hole, the second water outlet hole and the third water outlet hole, the first water outlet hole tilts downward to spray water to the upper end of the corresponding sewage treatment plate, the third water outlet hole tilts upward to spray water to the lower end of the corresponding sewage treatment plate, and the second water outlet hole sprays water in the direction of the corresponding sewage treatment plate.

[0069] The first water outlet, the second water outlet and the third water outlet spray water to the sewage treatment disc from multiple angles and directions, which can further promote the water flow rate at the sewage treatment disc and increase the sewage treatment efficiency of the microorganisms on the sewage treatment disc. At the same time, the effect of the water outlet from the first water outlet, the second water outlet and the third water outlet on the sewage treatment disc can further prevent smaller floating objects from clogging the sewage treatment disc and the water outlet, thereby improving the sewage treatment efficiency.

[0070] In some embodiments, three sewage treatment trays 3 are arranged below the suspension plate 1. The three sewage treatment trays 3 are arranged in sequence from top to bottom. The three sewage treatment trays 3 are each provided with a plurality of first water outlets, a plurality of second water outlets and a plurality of third water outlets.

[0071] In some embodiments, the height of the upper end of the filter barrel 2 is higher than the suspension plate 1. When the upper end opening of the filter barrel 2 is opened, the upper end opening of the filter barrel 2 is lower than the suspension plate 1 and lower than the water surface. At this time, there will be a gap between the filter barrel 2 and the suspension plate 1. However, this system is mainly used to isolate larger sewage and garbage, and the gap between the filter barrel 2 and the suspension plate 1 is small. Therefore, larger sewage and garbage will not enter the sewage treatment plate 3 through the gap between the filter barrel 2 and the suspension plate 1.

[0072] In addition, plants are planted on the suspension plate 1 , and the plants will further block the gap between the filter barrel 2 and the suspension plate 1 , further preventing water garbage from entering the sewage treatment plate 3 .

[0073] Example 3

[0074] On the basis of the above embodiment, a separation barrel 10 is provided inside the filter barrel 2, such as Figure 7 As shown, the upper end of the separation barrel 10 is detachably connected to the upper end of the filter barrel 2 , and the separation barrel 10 is used to separate garbage so that the garbage is located in the separation barrel 10 .

[0075] When the system is placed in water, the upper opening of the filter barrel 2 is located below the water surface. When the upper opening of the filter barrel 2 is opened, since the upper end of the separation barrel 10 is detachably connected to the upper end of the filter barrel 2, the sewage automatically flows into the separation barrel 10 under the action of gravity, and the sewage will not directly enter between the filter barrel 2 and the separation barrel 10. After passing through the separation barrel 10, the sewage leaves the garbage in the separation barrel 10, and the filtered water enters between the filter barrel 2 and the separation barrel 10. The filtered water enters the sewage treatment plate 3 through the water outlet.

[0076] In some embodiments, a first pressure plate 9 is provided in the separation barrel 10, a second pressure plate 11 is provided between the filter barrel 2 and the separation barrel 10, a first telescopic rod 13 is provided on the first pressure plate 9, and a second telescopic rod 12 is provided on the second pressure plate 11. The first telescopic rod 13 and the second telescopic rod 12 are telescopically extended to drive the first pressure plate 9 and the second pressure plate 11 to move up and down.

[0077] When the opening at the upper end of the filter barrel 2 is opened, Figure 7 As shown, the second telescopic rod 12 and the first telescopic rod 13 are shortened, the first pressing plate 9 and the lower end of the baffle 6 are in contact with each other, and the water enters the filter barrel 2 through the opening at the upper end of the filter barrel 2.

[0078] When the filter barrel 2 is completely filled with sewage, the first telescopic rod 13 and the second telescopic rod 12 are adjusted to extend the first telescopic rod 13 and the second telescopic rod 12, and the first pressing plate 9 and the second pressing plate 11 are located on the same horizontal straight line. Figure 8 At the same time, the first telescopic rod 13 and the second telescopic rod 12 are adjusted to extend the first telescopic rod 13 and the second telescopic rod 12, and the first pressing plate 9 and the second pressing plate 11 move downward, as shown. Fig. 9 As shown, the sewage and garbage in the sewage treatment disc 3 are squeezed, so that the separated sewage flows into the space between the filter barrel 2 and the separation barrel 10 through the separation barrel 10, and is discharged through the water outlet on the filter barrel 2.

[0079] The upper end of the second telescopic rod 12 is connected to the upper end of the separation barrel 10, and the upper end of the first telescopic rod 13 is connected to the baffle 6. When the telescopic rod 7 is shortened, the opening at the upper end of the filter barrel 2 is closed, and the baffle and the opening at the upper end of the filter barrel 2 are in contact with each other, the first pressing plate 9 is in contact with the upper end of the filter barrel 2. Fig.10 As shown, the opening at the upper end of the filter barrel 2 is closed to prevent water from entering the separation barrel 10.

[0080] Example 4

[0081] Based on the above embodiments, Fig.11 As shown, a connecting mechanism 8 is provided at the lower end of the first connecting rod 4, and the connecting mechanism 8 is used to be inserted into the underwater soil to fix the system.

[0082] The connection mechanism 8 can be of various structures, and can be a connecting rod with a pointed tip at the lower end, or can be of other structures, as long as it can achieve insertion connection.

[0083] In some embodiments, the connecting mechanism 8 is a fixed tripod. When treating sewage, aquatic plants are planted on the upper end through a suspended board and float on the water surface, and the fixed tripod at the lower end is inserted into the soil, thereby further fixing the position of the system.

[0084] In some embodiments, the suspension board is provided with a plurality of planting grooves, and plants are planted inside the planting grooves. A solar energy component is provided on the suspension board. An air ring is fixedly connected to the outer side of the suspension board, and the solar energy component includes a solar cell panel, and an angle adjustment shaft is provided at the bottom of the solar cell panel, and a first motor for adjusting the horizontal angle of the solar cell panel is provided at the bottom of the angle adjustment shaft, and a second motor for adjusting the elevation angle of the solar cell panel is provided at the top of the angle adjustment shaft.
