[0032] The dispersion flocculation area 4 is arranged in the module base 1 and communicated with the trapping inclined plane frame 301 at one end, the dispersion flocculation area 4 is arranged in a recessed cavity in the module base 1, and the sewage entering the dispersion flocculation area 4 can form a pool, and a flocculation agent can be added to the pool to make the pollutants in the pool flocculate and float or suspend.

[0033] The biological remediation module 5 is detachably arranged in the dispersion flocculation area 4 and has vegetation planted thereon, wherein the vegetation comprises water hyacinth and reed, the water hyacinth is arranged close to the sliding module 3, and the reed is arranged away from the sliding module 3, and the vegetation is planted in the dispersion flocculation area 4, the dispersion flocculation area 4 can flocculate the pollutants into suspended matter or floating matter, which is beneficial to the water hyacinth to absorb, and the heavy sediment can be absorbed by the root system of the reed, so as to form a comprehensive biological remediation system.

[0034] The standing sedimentation module 6 comprises an installation frame 601 fixedly connected to the other end of the module base 1, and a plurality of light filler filter blocks 602 are filled in the installation frame 601, and flow-through gaps 603 are arranged between the light filler filter blocks 602, the flow-through gaps 603 are arranged to increase the contact area between the water and the light filler filter blocks 602, the water can only be purified by the biological absorption of the biological remediation module 5, and the flow speed of the water needs to be reduced again when the water passes through the standing sedimentation module 6, and a treatment agent is filled in the standing sedimentation module 6, so that another part of the pollutants can be purified by the chemical agent, so as to form a three-fold purification system, the low-pollution water source is purified, and the purified water is discharged into the ecological safety buffer area, so as to reduce the pollution of the ecological safety buffer area, the water is in the acceptance range of the ecological safety buffer area, and the safety is improved.

[0035] As shown in FIG. 1, the device comprises a sliding module 3, a dispersion flocculation area 4, a biological remediation module 5 and a standing sedimentation module 6. Figure 2As shown in the drawings, in some embodiments, the module base 1 comprises a rectangular frame 101 with an open upper end, and a T-shaped block 102 and a U-shaped groove block 103 connected to the two sides of the rectangular frame 101, respectively. The T-shaped block 102 and the U-shaped groove block 103 are connected in a head-to-tail manner, so that multiple rectangular frames 101 can be connected to each other, improving the stability of the connection and avoiding disconnection caused by external environment. After connection, a treatment belt can be formed between the low-pollution water body discharge area and the ecological safety buffer zone, so as to ensure that the sewage is treated multiple times before being discharged into the ecological safety buffer zone, and to avoid the sewage with too high pollution level from entering the ecological safety buffer zone and causing damage.

[0036] As shown in the drawings, Figure 1 and Figure 3 As shown in the drawings, in some embodiments, the sewage diversion pipe 2 comprises a main flow pipe 201, and a plurality of diversion pipe heads 202 are arranged on one side of the main flow pipe 201 along the length direction and connected to one end of the rectangular frame 101. A threaded sleeve 203 is rotatably installed at one end of the main flow pipe 201, and a plug-in pipe 204 is arranged at the other end of the main flow pipe 201. The outer side of the plug-in pipe 204 is wrapped with a connecting pipe 205 which is threadedly connected with the threaded sleeve 203. When the low-pollution water body enters the main flow pipe 201, it will be diverted by the diversion pipe heads 202, so as to uniformly cover the sliding module 3, thereby reducing the flow rate in one area and ensuring the pollutant interception effect of the interception inclined frame 301. The plug-in pipe 204, the threaded sleeve 203 and the connecting pipe 205 can facilitate the butt joint of multiple main flow pipes 201, thereby ensuring the smooth flow of sewage and facilitating installation and disassembly, and improving the flexibility of the device.

[0037] As shown in the drawings, Figure 2 As shown in the drawings, in some embodiments, the rectangular frame 101 is made of porous concrete plate material and is embedded in the ground. The specific material is cement-aggregate-based porous lightweight filler. During the hydration process, calcium silicate hydrate (C-S-H) product is generated, which is one of the main products of cement hydration reaction. It is a cementitious material that can fill the micropores and voids in cement mortar, thereby improving the compactness and strength of the mortar. At the same time, C-S-H is also the main release agent in cement mortar, which can slowly release alkali ions, thereby avoiding excessive alkali ions in cement mortar, causing alkali skeleton reaction and corrosion of steel bars in concrete. The device can improve the stability and also perform acid-base neutralization treatment on the sewage.

[0038] As shown in the drawings, Figure 1 and Figure 4As shown in the drawings, in some embodiments, the trapping inclined plane frame 301 comprises a trapezoidal frame 3011, and the trapezoidal frame 3011 is filled with support blocks 3012, the upper surface of the support blocks 3012 is in an inclined configuration, and a plurality of trapping protrusions 3013 are arranged along the inclined direction of the upper surface of the support blocks 3012, and a permeation hole 302 is arranged between every two trapping protrusions 3013. It should be noted that the support blocks 3012 are made of light foam material, which is convenient for subsequent replacement and cleaning, and the trapping protrusions 3013 can reduce the flow rate of sewage, so that the particulate pollutants in the sewage can be precipitated into the permeation holes 302, thereby ensuring the treatment effect.

[0039] As shown in the drawings, Figure 1 and Figure 3 As shown in the drawings, in some embodiments, the dispersion flocculation zone 4 is arranged in the rectangular frame 101 and the bottom is arranged with a plurality of aeration holes 401, and the aeration holes 401 are fixedly connected with flow-through pipes 402 which are connected with the main flow pipe 201. It should be noted that the flow-through pipes 402 are connected to the upper side of the main flow pipe 201, and the flow-through pipes 402 can receive the gas pressure of the main flow pipe 201, and the gas is pressed into the aeration holes 401 by the pressure of the main flow pipe 201, and then floats up from the dispersion flocculation zone 4. This process can make the pool water in the dispersion flocculation zone 4 churn, thereby improving the flocculation efficiency and the contact area between the pollutants and the plant roots, and increasing the purification effect.

[0040] As shown in the drawings, Figure 1 and Figure 3 As shown in the drawings, in some embodiments, the aeration holes 401 are hingedly connected with one-way covers 403 which are turned upward, one end of the one-way cover 403 is hingedly connected to the edge of the aeration hole 401, and a torsional spring is installed on the hinge shaft, so that the one-way cover 403 always has a tendency to turn downward, but is blocked by the edge of the aeration hole 401, forming a one-way valve cover, thereby reducing the amount of backflow of sewage and ensuring that the gas can be smoothly sprayed out.

[0041] As shown in the drawings, Figure 2 As shown in the drawings, in some embodiments, the biological remediation module 5 comprises a plurality of adsorption nets 501 which are arranged in sequence along the length direction of the dispersion flocculation zone 4, and a plurality of wave-shaped isolation plates 502 are connected between the adsorption nets 501 and arranged along the length direction of the dispersion flocculation zone 4. The adsorption net 501 is made of steel wire mesh and covered with a layer of activated carbon, which can be used for limiting the growth of floating plants such as water hyacinth, and can also filter and adsorb sewage to increase the purification effect. The wave-shaped isolation plate 502 can divide the water flow and the flocculation material into multiple paths, and uniformly contact with the vegetation, so that the pollutants are within the treatment capacity of the vegetation, and the flow rate is reduced, thereby increasing the treatment effect.

[0042] As shown in the drawings, Figures 1-2As shown in the drawings, in some embodiments, the adsorption nets 501 are arranged in the dispersion flocculation zone 4, and the distance between any two of the adsorption nets 501 is gradually increased from the sliding module 3 to the static precipitation module 6. By using the distribution of the adsorption nets 501, the aquatic plants in the dispersion flocculation zone 4 can form multiple plant barrier layers, so as to facilitate the filtration and purification treatment of the sewage and improve the treatment effect.

[0043] As shown in the drawings, Figure 1 and Figure 5 As shown in the drawings, in some embodiments, the mounting frame 601 includes a rectangular net frame 6011 fixedly connected to the end side of the rectangular frame 101. The inner bottom of the rectangular net frame 6011 is provided with a grid bar 6012. Lightweight filler blocks 602 are respectively inserted into the inner holes of the grid bar 6012. The grid bar 6012 is used to position the lightweight filler blocks 602, facilitating the installation and disassembly operation of the lightweight filler blocks 602. The lightweight filler blocks 602 are made of cement polymer-based porous lightweight fillers, which are composed of cement, lightweight aggregate, polymer and other additives. The cement polymer-based porous lightweight filler can be used for adsorption and degradation of pollutants in water purification. When the cement polymer-based porous lightweight filler contacts with water, the hydroxyl ions (OH-) on the surface of the filler will have an ion exchange reaction with the cations in the water, thereby adsorbing the pollutants in the water onto the surface of the filler. At the same time, the hydroxyl groups on the surface of the filler can also have a chemical reaction with the pollutants in the water, thereby realizing the degradation of the pollutants and improving the purification effect of the water body.

Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present application. Therefore, the present application will not be limited to these embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
