Description

Technical Field

[0001] The present application relates to the technical field of ecological environment governance, and in particular to an ecological rural river restoration method. Background Art

[0002] Rural rivers undertake basic functions such as agricultural irrigation and drainage, flood regulation and diversion, and ship transportation. They are also important carriers of the ecology and environment in rural areas.

[0003] Currently, the methods for urban river water restoration can be roughly divided into physical methods, chemical methods and biological-ecological methods.

[0004] Physical methods of restoration include aeration, sewage interception and river dredging. If artificial aeration measures are taken at appropriate locations in the river, the activity of aerobic microorganisms in the water body can be improved. This reduces the pollution of the water body and achieves the purpose of improving water quality. Sewage interception is also an effective way to use physical methods to repair water bodies. From 1991 to 2001, France invested a total of 5.6 billion euros to intercept sewage in the Seine River, and the sewage treatment rate increased by 30% on the original basis, with significant results. As for the study of river dredging measures, Wang Dong and others removed 30% of the phosphorus in the sediment by physical methods such as dredging and dredging in the Wuli Lake area of ​​Taihu Lake, and also had a good effect on the removal of nutrients in the water body. However, river dredging is often a measure that cannot fundamentally solve the problem of water pollution. Pu Peimin and others analyzed that river dredging projects have important uses as water conservancy projects and waterway engineering measures, and their effect on improving water quality is related to the dredging method. Appropriate dredging can improve water quality in the short term, but in the long run, dredging sediment is not an effective measure to control lake eutrophication. Physical methods often only treat the symptoms and not the root cause, and are not the ultimate solution to the problem.

[0005] Chemical methods for water pollution control mainly use two ways: chemical fixation and chemical algae removal. Chemical fixation mainly uses chemical substances to precipitate water phosphorus or heavy metals in the bottom mud and prevent them from being released again from the bottom mud. Studies have shown that Ca(NO3)2 can effectively degrade organic matter in the bottom mud and inhibit the release of bottom mud phosphorus. Chemical algae removal mainly inhibits the reproduction of algae in polluted water bodies by adding chemical agents, such as copper sulfate algaecides, non-oxidizing algaecides, etc. Ning Ping et al. used ferric chloride to conduct algae removal experiments in response to the outbreak of blue algae in Dianchi Lake, and found that the type of flocculant and pH value have an effect on the removal rate of blue algae. However, the use of chemical methods often causes secondary pollution of water bodies. Li Jianhong and others found through research that the copper ions in copper sulfate can act on the blue algae gallbladder, thereby inhibiting the photosynthesis of blue algae themselves and achieving the effect of killing algae. However, the chemical algae removal method using copper sulfate will kill a large number of microorganisms and destroy the water ecosystem. Generally speaking, the use of chemical methods for water restoration can produce immediate results in a short period of time, but it is very easy to cause secondary pollution of the water body and can only be used as a preliminary means of ecological restoration and an emergency control technology.

[0006] Ecological-biological methods restore water quality according to natural laws and repair polluted water bodies by strengthening the interaction between natural organisms or the self-purification ability of the water body itself. They mainly include: aquatic plant ecological restoration technology, ecological slope (bank) protection technology, and microbial restoration technology.

[0007] In the aquatic plant ecological restoration technology, the technology of using aquatic plants as raw materials to build artificial floating islands or artificial sinking beds for water ecological restoration is becoming more and more perfect.

[0008] The existing artificial floating island (or artificial floating bed) technology only has the functions of floating and convenient installation, and has little effect on the water flow and cannot change the water flow, making it single-function and not easy to use. Summary of the invention

[0054] In the description of the present application, it should be understood that the terms "center", "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating positions or positional relationships, are based on the positions or positional relationships shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present application. In the description of the present application, unless otherwise specified, "multiple" means two or more.

[0055] It is found in practice or experiments that the purification effect of the plants in the water will be different when the water flow rate is different. This difference is in the form of a parabola. The top of the parabola is the corresponding flow rate under the optimal purification state of the plant. In the rectangular coordinate system, the horizontal axis is the flow rate and the vertical axis is the purification effect, thus obtaining a parabola. Therefore, the technical means of this application mainly revolves around how to find the optimal purification flow rate for the aquatic plant in the river. Due to the differences in rivers, the aquatic plants growing around each river are different, so it is necessary to adaptively search for each river separately to find the best purification solution.

[0056] exist Fig.10 In the schematic diagram of the river and its detection point settings, the river C, the rest, the first detection point A1, the second detection point A2, the third detection point A3, the first river channel B1, the second river channel B2, in the attached Fig.10 In the figure, two bends are taken as an example, so the first river channel B1 and the second river channel B2 in the figure are respectively bends.

[0057] See also Figure 1-Figure 10 As shown, an exemplary ecological rural river restoration method of the present application includes the following steps:

[0058] S10. An artificial floating bed is set up to form new turbulence on the surface of the river C and change the flow velocity and flow direction on the surface of the river C.

[0059] In the present application, a new turbulence is formed on the river surface through the flow disturbance structure on the artificial floating bed, thereby changing the flow velocity and flow direction on the river surface.

[0060] In some preferred embodiments, the entire artificial floating bed is made of plastic structure, wherein the outer frame 11 is relatively large and hollow to provide sufficient buoyancy.

[0061] In some preferred embodiments, the artificial floating bed includes an outer frame 11, an inner frame 12, a sleeve 20, a connecting rib 13, a guide vane 60, an arm 70, and an assembly buckle 80;

[0062] A plurality of inner frames 12 are placed in the outer frame 11, and the plurality of inner frames 12 are arranged in sequence with decreasing inner diameters;

[0063] The outer frame 11 is fixedly connected to the inner frame 12 via the connecting ribs 13, so that the outer frame 11 and the plurality of inner frames 12 are connected and fastened;

[0064] A plurality of arm rods 70 are fixed to the outer side wall of the outer frame 11, and the plurality of arm rods 70 are evenly distributed around the outer frame 11;

[0065] The end of the arm 70 is fixedly connected with the assembly buckle 80;

[0066] The sleeve 20 is sleeved in the innermost layer of the inner frame 12, and the sleeve 20 is a multi-layer structure; each two adjacent layers of the sleeve 20 are connected and fixed by reinforcing ribs;

[0067] The guide vane 60 is fixedly installed below the connecting rib 13 ; the guide vane 60 is arranged along any diameter direction of the inner frame 12 .

[0068] In some preferred embodiments, two guide vanes 60 are provided, and the two guide vanes 60 are located on the same plane; and the two guide vanes 60 are respectively located on both sides of the sleeve 20 .

[0069] In some preferred embodiments, the guide vane 60 is placed vertically.

[0070] The function of the guide plate 60 in this application is to form turbulence on the surface of the river, thereby changing the flow velocity and flow direction of the water on the surface of the river. The change of water flow velocity is very important in this application. The formation of turbulence or disturbance is to change the flow velocity of the water flow in this application, and then form the water purification capacity at the flow velocity according to the flow velocity.

[0071] In the present application, the placement direction of the guide plate 60 has a greater impact on the water flow, and forms at least four directions. When multiple artificial floating beds are combined, more possible combinations can be formed. Furthermore, at least four types of turbulence effects are formed.

[0072] In some preferred embodiments, a spoiler column 50 is further included, and a plurality of the spoiler columns 50 are respectively fixed on the lower surface of the inner frame 12, and the spoiler columns 50 are placed vertically;

[0073] It also includes an indicator strip 30 ; the indicator strip 30 is installed on the upper surface of the connecting rib 13 , and the indicator strip 30 is arranged corresponding to the guide vane 60 , so that the direction of the guide vane 60 can be understood through the indicator strip 30 .

[0074] In the present application, the spoiler column 50 is used to increase the spoiler effect on the river surface, thereby forming more turbulence on the river surface.

[0075] Since the spoiler columns 50 are arranged evenly and without direction, no matter at what angle the outer frame 11 is placed, there is no big difference in the effect of the spoiler columns 50 .

[0076] In some preferred embodiments, it further includes a base 90, a weighted sphere 42, and a fixing rod 41;

[0077] The base 90 is installed in the middle of the innermost layer of the sleeve 20;

[0078] The weighted sphere 42 is fixedly connected to the base 90 via the fixing rod 41 , so that the fixing rod 41 and the axis of the sleeve 20 are in the same straight line.

[0079] In the present application, the base 90 is used to support plants.

[0080] In some preferred embodiments, the multiple layers of the sleeve 20 are in a state where the height increases from the outside to the inside.

[0081] The sleeve 20 is provided with a through hole to connect the inside and the outside of the sleeve 20 .

[0082] In some preferred embodiments, eight arm rods 70 are provided, and the eight arm rods 70 are evenly distributed;

[0083] The assembly buckle 80 includes a bottom plate 81, a first wedge block 82 and a second wedge block 83; the inclined surface of the first wedge block 82 and the inclined surface of the second wedge block 83 face oppositely, and the cross-sectional areas of the ends of the first wedge block 82 and the second wedge block 83 close to the bottom plate 81 are small, and the cross-sectional areas of the ends away from the bottom plate 81 are large;

[0084] The outer frame 11 is a hollow structure, and the inner frame 12 is a solid structure; the outer frame 11, the inner frame 12, and the arm 70 are made of the same plastic material.

[0085] The working principle of the relevant structure of the artificial floating bed in this application is described as follows:

[0086] 1) Plants are planted in the innermost layer of the sleeve 20 and supported on the bottom support 90; then the entire artificial floating bed is placed on the river surface to float.

[0087] 2) Since the sleeve 20 is a multi-layer structure, and the depth of each layer is different, the depth of each layer increases from the outside to the inside, so as to protect the growth of plants and play a role of step-by-step flow disturbance.

[0088] 3) The sleeve 20 and the outer frame 11 are connected and fixed by connecting ribs 13, and a plurality of inner frames 12 are provided to enhance the stabilization and fixing effect; at the same time, compared with the prior art, the overall weight of the artificial floating bed is reduced.

[0089] 4) The spoiler column 50 disturbs the water flow on the river surface, and the direction and speed of the water flow are changed.

[0090] 5) The through holes are provided to facilitate water to enter the innermost layer of the sleeve 20, so as to facilitate the inflow and outflow of water, thereby achieving a better effect of purifying water quality; and because the through holes are small, they will not affect the growth of plants and the growth of roots.

[0091] 6) The counterweight sphere 42 serves to increase the counterweight. The counterweight sphere 42 is placed in the center and is connected and fixed by a rope or a fixing rod 41. In some schemes, the counterweight sphere 42 adopts a solid sphere structure wrapped in plastic to increase the weight and improve the stability of the floating bed.

[0092] 7) The arm 70 is used to support and stabilize the connection between two floating beds; the assembly buckle 80 is used to connect and fix the two arm 70; the assembly buckle 80 has two wedges with trapezoidal cross sections. When assembling, it is necessary to forcefully pull to expand the opening, so as to buckle the two wedges and prevent them from loosening. Furthermore, in this application, the assembly buckle 80 needs to have a certain deformation ability. However, the assembly buckle 80 cannot be too soft, otherwise it cannot ensure good assembly stability; nor can it be too hard, otherwise it will be inconvenient to connect and buckle the two assembly buckles 80.

[0093] 8) The guide plate 60 is used to guide the water flow so as to change the water flow in the straight direction into the oblique water flow. In this process, the direction of the water flow changes, and then the speed of the water flow in the straight direction also slows down.

[0094] 9) The guide plate 60 and the indicator bar 30 are a set of components used as a set. The indicator bar 30 is located above the inner frame 12, and the guide plate 60 is located below the inner frame 12. The directions of the guide plate 60 correspond to those of the indicator bar 30, so that the direction of the guide plate 60 can also be understood from above.

[0095] 10) Arms 70 are provided in eight directions, so there are at least two ways of assembling two artificial floating beds, as shown in the attached figure. The difference between the two connection methods is that the relative positions of the two artificial floating beds are different, one is in the same horizontal direction, and the other is in an oblique direction. The figure shows the possible assembly forms and states of the artificial floating beds.

[0096] S20, selecting a first river channel B1 and a second river channel B2 on the same river.

[0097] In some preferred embodiments, the first river channel B1 is a straight channel or a curved channel, and the second river channel B2 is a straight channel or a curved channel.

[0098] In some preferred embodiments, the first river channel B1 is a bend, and the second river channel B2 is a bend, and they form a first river bay and a second river bay.

[0099] There are two ways to form a curve. One is that it exists naturally, so it can be selected directly; the other is that it does not exist naturally and is obtained through artificial excavation.

[0100] S30, placing artificial floating beds in different states in the first river channel B1 and the second river channel B2 respectively; setting a plurality of the artificial floating beds in a first state on the first river channel B1; and setting a plurality of the artificial floating beds in a second state on the second river channel B2.

[0101] In some preferred embodiments, the connection state of two adjacent artificial floating beds includes a lateral connection and an oblique connection.

[0102] The first state and the second state described in the present application respectively represent the connection states of two different artificial floating beds, which mainly include two aspects: one is the placement state of the guide plate 60, and the other is the connection state of the two artificial floating beds.

[0103] A single artificial floating bed has four placement states of the guide vanes 60, such as Fig. 9 As shown; then, two artificial floating beds are connected to form 4^2=16 placement states of the guide vanes 60. If six artificial floating beds are set in the same river channel, then 4^6=4096 placement states of the guide vanes 60 will be formed. One of the 4096 is selected at the first river channel B1, and another of the 4096 is selected at the second river channel B2.

[0104] There are only two types of connection between two artificial floating beds, one is horizontal connection and the other is oblique connection. For oblique connection, there are usually only two situations, one is located at the left rear and the other is located at the right rear; as shown in the attached figure Figure 8 shown.

[0105] In the attached figure ( Figure 7 and Figure 8 ) shows only the case where all guide vanes 60 of the artificial floating bed are in the same direction. The drawings do not provide detailed examples of the connection states of the guide vanes 60 in different situations. Please refer to the drawings of the guide vanes 60 of a single artificial floating bed at different angles.

[0106] S40, respectively detecting the water purification capacity of the first river channel B1 and the second river channel B2; respectively detecting the water quality upstream of the first river channel B1, between the first river channel B1 and the second river channel B2, and downstream of the second river channel B2, and calculating the water purification results passing through the first river channel B1 and the second river channel B2.

[0107] In some preferred embodiments, detection points are respectively set at the upstream of the first river channel B1, between the first river channel B1 and the second river channel B2, and downstream of the second river channel B2, and form a first detection point A1, a second detection point A2, and a third detection point A3 respectively;

[0108] A first water quality result is obtained through the first detection point A1, a second water quality result is obtained through the second detection point A2, and a third water quality result is obtained through the third detection point A3;

[0109] By calculating the difference between the first detection point A1 and the second detection point A2, the purification effect of the first river channel B1 is obtained;

[0110] By calculating the difference between the second detection point A2 and the third detection point A3, the purification effect of the second river channel B2 is obtained;

[0111] Compare the purification effects of the first river channel B1 and the second river channel B2 to obtain a better solution.

[0112] S50, find a better water purification solution; compare the water purification capabilities of the first river channel B1 and the second river channel B2, if the purification effect of the first river channel B1 is better, lay the artificial floating bed in the river in the first state; if the purification effect of the second river channel B2 is better, lay the artificial floating bed in the river in the second state.

[0113] In some preferred embodiments, the flow disturbances of the plurality of guide vanes 60 are arranged in parallel so that the flow disturbances of the plurality of artificial floating beds are arranged in the same direction;

[0114] Alternatively, the plurality of guide plates 60 are arranged in a vertical direction, so that the disturbance directions of the plurality of artificial floating beds are vertical.

[0115] In the technical solution of the present application, the best plants are aquatic plants, and the best plants are those in the river, followed by other plant species or aquatic plants in other places.

[0116] In the present application, the sleeve 20, guide plate 60, spoiler column 50 and through hole of the artificial floating bed are the most important features, which play a vital role in the realization of the scheme and the technical effect. Because these structures or features can play a role of spoiler and change the flow velocity and flow direction, the surface flow velocity of the river changes, thereby producing a purification effect at the flow velocity.

[0117] The ecological rural river restoration method described in the present application is to set up an artificial floating bed with turbulence that changes the surface of the river, and use it in two different states; then, the artificial floating bed of the present application can have at least two combined assembly methods, and can form at least two combination states, one of which is placed in the first river channel B1, and the other is placed in the second river channel B2. The combination of artificial floating beds in each state has different effects on the change of the water flow on the river surface, or a great impact, or a small impact, so that the river flow rate in the purified state is also different. It was found in the experiment that the purification effect of water quality is different at different flow rates. Therefore, through the technical means of the present application, a better way to purify water quality can be found in two combined states, and then a water purification combination that is more suitable for the river can be found, and then the water quality of the river can be better purified.

[0118] Supplementary description of some effects of the ecological rural river restoration method of this application:

[0119] 1) The artificial floating bed in the present application is set up to disturb the water flow on the river surface, changing the flow direction and flow rate. Since there are two assembly and connection methods of the artificial floating bed, two disturbance methods are formed, and the impact on the water flow is different, so the water purification capacity of the artificial floating bed combination in the two states can be judged. The judgment is based on the river and the aquatic plants in the river, which has better adaptability and accuracy.

[0120] 2) The flow rate of each river is different, and the influencing factors of local suitable aquatic plants are different. Therefore, if you need to find the most suitable purification method, you need to find the most suitable water flow rate. Through the method of this application, you can find the most suitable purification flow rate for the river.

[0121] 3) Based on the purification effect, find a more suitable purification method and use it as the water purification plan for the river.

[0122] 4) Through this application, a targeted river purification method can be obtained.

[0123] The above-mentioned embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the patent application. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application.
