These problems not only affect the ecological environment but also adversely affect the quality of life of residents and the image of the city.

[0003] A slope sewage treatment system refers to a system that combines the characteristics of sloping terrain, organically combines sewage treatment processes with topography and geomorphology, and uses physical, chemical, and biological methods to efficiently purify and treat sewage, ultimately meeting discharge standards or reuse standards. As a sewage treatment solution specifically designed for sloping terrain or water body slopes, the design and application of a slope sewage treatment system are of great significance in improving water body environments, increasing sewage treatment efficiency, and conserving land resources. Slope sewage treatment systems are mainly used in aquaculture wastewater treatment, rural domestic sewage treatment, and urban slope area sewage treatment scenarios.

The domestic sewage then enters a pit pond or a river through a water collection system at the bottom of the second-level surface flow artificial wetland. Cattails or dwarf reeds are planted on the slope of the pit pond or river with a water depth of 0.2-1.0 m, and an artificial ecological floating island is arranged at a water depth of 1.5-2.5 m. Aquatic plants are planted on the artificial floating island. This utility model utilizes existing pit ponds and rivers in rural areas to greatly reduce construction costs. It does not require professional operation and management, only needs periodic cleaning, and reduces maintenance costs and equipment operation costs. The entire system has good greening landscape effects and meets the current concept of building a beautiful rural home;

A microbial attachment layer 52 is arranged between the two filter material carriers 51 in each group. The microbial attachment layer 52 is used for the attachment of microorganisms, so as to degrade organic matter by the metabolic activity of microorganisms and achieve the effect of sewage treatment.

[0055] In this embodiment, the water inlet end of the first water channel 1 is provided with a water inlet channel 15. The bottom of the water inlet channel 15 is provided with protrusions 151 on the left and right sides. The protrusions 151 are integrally formed on the water inlet channel 15. A support frame 152 is arranged on the top surface of the water inlet channel 15. The left and right side plates of the support frame 152 are rotatably connected to the two protrusions 151. Two shafts 16 are connected by a mesh conveyor belt 162 in a head-to-tail manner. Specifically, the shaft 16 is provided with two chain wheels that are symmetrical to each other. The mesh conveyor belt 162 is sleeved on the chain wheel part of the shaft 16 and is engaged with the chain wheel.

When the mesh conveyor belt 162 rotates, the barb 163 can convey more impurities along the mesh conveyor belt 162 and fall from the end of the mesh conveyor belt 162, thereby achieving impurity cleaning operation.

[0056] As Figure 2 shown, the first water channel 1 and the second water channel 10 are provided with a first partition plate 13. The height of the first partition plate 13 is less than the depth of the first water channel 1. The liquid level in the first water channel 1 is higher than the first partition plate 13, so that the liquid can flow into the second water channel 10 for further sedimentation operation.

[0057] Specifically, the corresponding harmless treatment liquid can be poured into the first water channel 1 and the second water channel 10 to further treat the sewage. The harmless treatment liquid can contain flocculants and the like to improve the treatment effect of the sewage.

[0058] AsFigure 2 As shown, a second partition 14 is installed between the second water channel 10 and the third water channel 11, and between the third water channel 11 and the fourth water channel 12. A gate 6 is provided on the second partition 14 to realize the blocking operation using the second partition 14, and at the same time, the water flow operation can be controlled using the gate 6. The gate 6 can also control the water flow rate.

[0059] like Figure 3 As shown, an operating panel 17 is installed on the top surface of the water inlet channel 15. The operating panel 17 is located in front of the support frame 152 and is used for personnel to stand and perform other operations. A discharge hopper 171 is provided above the operating panel 17. An inclined discharge plate 18 is installed on the front side of the top plate of the support frame 152. The inclined discharge plate 18 is located directly above the discharge hopper 171, so that impurities falling from the top of the mesh conveyor belt 162 can fall along the surface of the inclined discharge plate 18 into the discharge hopper 171 and be discharged outward with the discharge hopper 171. The plane on which the top surface of the inclined discharge plate 18 is located is inclined downward at 45°~60°, and the discharge hopper 171 is inclined downward at 45°~75°. The discharge end of the discharge hopper 171 extends to the outside of the water inlet channel 15, so that impurities can be discharged outward more smoothly along the inclined discharge plate 18 and the discharge hopper 171, which is conducive to the discharge operation.

[0060] It is worth noting that the bottom of the unloading hopper 171 is equipped with multiple vertically arranged support legs 172. The support legs 172 at the bottom of the unloading hopper 171 are divided into two groups. One group is installed on the top surface of the operating plate 17, and the other group is installed on the outer bottom surface to achieve stable support operation. Steps 19 are provided on the sides of the operating plate 17 and the water inlet channel 15. The steps 19 make it easier for personnel to walk up to the operating plate 17.

[0061] It is worth noting that the front end of the water inlet channel 15 is provided with a filter assembly 3, which includes two left and right symmetrical slide rails 30 installed on the inner walls of the left and right sides of the water inlet channel 15. The slide rails 30 are vertically arranged, and the slide rails 30 are provided with slide grooves 301 arranged along the height direction of the slide rails 30. The front side plate 31 and the rear side plate 32 are inserted and connected between the two slide grooves 301. The rear side plate 32 is located behind the front side plate 31. The fine filter screen 311 is installed on the front side plate 31. The coarse filter screen 321 is installed on the rear side plate 32. The rear side plate 32 and the front side plate 31 are both rectangular ring structures. The fine filter screen 311 and the coarse filter screen 321 are used for water filtration operation, which realizes further filtration operation on the water body. The top surface of the slide rail 30 is provided with a cover plate 33 which is tightly pressed on the top surface of the front side plate 31 and the rear side plate 32. The cover plate 33 is fixedly connected with the slide rail 30 through a plurality of fastening bolts, which is convenient for installation operation. At the same time, the cover plate 33 can press the front side plate 31 and the rear side plate 32, which has the effect of fixing. After the cover plate 33 is disassembled and opened, the fine filter screen 311 and the coarse filter screen 321 can be taken out for replacement operation, which is convenient to use.

[0062] In this embodiment, the gate 6 includes a water pipe 60 installed on the second partition plate 14. The cross section of the water pipe 60 is hollow rectangular shape. The top wall of the water pipe 60 is provided with a sliding hole 601 which is connected with the outside. The length of the sliding hole 601 is equal to the inner diameter of the water pipe 60. The top surface of the water pipe 60 is provided with a U-shaped frame 61. The left and right inner walls of the U-shaped frame 61 are both provided with guide grooves 611. The top plate body of the U-shaped frame 61 is provided with a gas cylinder 62. The telescopic shaft end of the gas cylinder 62 is provided with a steel plate 621. The bottom surface of the steel plate 621 is provided with a sliding bar 63. The end plate body of the sliding bar 63 is located in the guide groove 611 and is slidingly connected with the guide groove 611, which has the effect of sliding guide. The bottom surface of the sliding bar 63 is provided with a blocking plate 64. The blocking plate 64 is located in the sliding hole 601 and is slidingly connected with the sliding hole 601. The blocking plate 64 is inserted and connected with the water pipe 60. The blocking plate 64 and the side surface of the water pipe 60 are mutually fitted. When the blocking plate 64 moves downward to the bottom surface and abuts against the bottom wall of the water pipe 60, it can have a better blocking effect.

[0063] In this embodiment, the bottom surface of the blocking plate 64 is provided with a cutting blade 66. The bottom wall of the water pipe 60 is provided with a cutting groove 65. The cutting blade 66 is located in the cutting groove 65 and is inserted and connected with the cutting groove 65. The size of the cutting blade 66 is matched with the size of the cutting groove 65. The cross section of the cutting blade 66 and the cutting groove 65 are both triangular shape. When the water algae and other things are stuck under the blocking plate 64, the cutting blade 66 moves downward, which can cut off the water algae and other things, avoiding the adverse effect on the normal closing of the blocking plate 64.

[0064] In this embodiment, the driving motor 161, the aeration pump 4 and the air cylinder 62 can all use low-power devices, or use devices with less noise, to reduce noise and achieve the effect of noise reduction.

[0065] In use, the first water channel 1, the second water channel 10, the third water channel 11, the fourth water channel 12, the end water channel 5, the curved water channel 50 and the water inlet channel 15 are laid, and then the soil stabilization bricks 20 are laid, and at the same time, the corresponding aquatic plants and other corresponding plants are planted in the first water channel 1, the second water channel 10, the third water channel 11, the fourth water channel 12 and the green plant planting hole 21. When the water inlet channel 15 is filled with water, the driving motor 161 is connected to the external power supply and made to work. The driving motor 161 works, and the output shaft on it rotates to drive the rotating shaft 16 to rotate, which in turn drives the mesh conveyor belt 162 to rotate, realizing the upward conveying of impurities flowing to the mesh conveyor belt 162 part in the water inlet channel 15 along the mesh conveyor belt 162. The impurities can fall from the end of the mesh conveyor belt 162 to the inclined discharge plate 18 part and fall along the surface of the inclined discharge plate 18 to the discharge hopper 171. The impurities finally fall out of the discharge hopper 171, completing the cleaning operation of the impurities.

[0066] In addition, the water that has been preliminarily cleaned by the mesh conveyor belt 162 can flow to the coarse filter screen 321 and the fine filter screen 311 for filtering operation. The filtered water enters the first water channel 1 for sedimentation operation. In addition, harmless liquid can be added to the first water channel 1 and the second water channel 10 for further treatment operation. When the first water channel 1 is full of water, the water in the first water channel 1 can flow to the second water channel 10 through the first partition plate 13 for further sedimentation treatment operation. In addition, as the water flows into the third water channel 11 and the fourth water channel 12, oxygen in the air can be used to biologically treat the sewage, realizing the degradation of organic matter and the removal of nitrogen and phosphorus. At the same time, the microbial adhesion layer 52 on the filter material carrier 51 can degrade organic matter using the metabolic activity of microorganisms. After the treated water enters the curved water channel 50, it can be treated in turn by the corresponding microbial adhesion layer 52. In addition, during the sewage treatment process, the aeration pump 4 can be connected to the external power supply and made to work. The aeration pump 4 works, which can increase the oxygen content in the water body and promote the decomposition of microorganisms.
