[0014] In order to make the technical problems, technical solutions and beneficial effects to be solved by the utility model clearer and more understandable, the following further details the utility model with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the utility model and are not used to limit the utility model.

[0015] As Figure 1 shown, it includes a sewage tank 1 installed on the ground. A filter grille is arranged in the sewage tank 1. The water outlet of the sewage tank 1 is connected to a multi-stage water filtering component 3. The clean water outlet of the multi-stage water filtering component 3 is connected to a clean water tank 4. A drain pipe 5 and a drain control valve are arranged on the clean water tank 4. The sewage outlet of the multi-stage water filtering component 3 is connected to a chemical dosing tank 6. The overflow port of the chemical dosing tank 6 is communicated with a filtering tank 7. An overflow pipe 8 is arranged on the filtering tank 7. The filtering tank 7 is also connected to the sewage tank 1 through a circulating water pipe 9. A water pump 10 is installed on the circulating water pipe 9.

[0016] In the present utility model, after the sewage in the sewage tank 1 is filtered by a filter grille, it enters the multi-stage water filtration assembly 3. The multi-stage water filtration assembly 3 performs multi-stage filtration on the sewage. The filtered clear water enters the clear water tank 4. A drain pipe 5 is installed on the clear water tank 4, and the drain pipe 5 can directly discharge the clear water. Part of the sewage enters the chemical dosing tank 6, where chemical dosing and stirring are carried out. The mixed liquid enters the filtration tank 7 through the overflow port. The filtration tank 7 is internally provided with a filter plate, and the supernatant liquid after being filtered by the filter plate is discharged through the overflow pipe 8. The sewage in the filtration tank 7 is circulated to the sewage tank through the circulating water pipe and the water pump for circulation. The entire system occupies a small area and is easy to maintain. It only needs to be regularly cleaned of the multi-stage water filtration assembly 3, the clear water tank 4, and the filtration tank 7, and the cleaning is convenient.

[0017] As Figures 2 to 3 shown, the multi-stage water filtration assembly 3 includes a fixing frame 11 and a plurality of water filtration tanks 12 installed on the fixing frame 11. The plurality of water filtration tanks 12 are arranged in sequence from top to bottom. The water filtration tanks 12 are connected to each other through water guiding curved grooves 13. A plurality of water filtration holes 14 are provided on the water filtration tanks 12, and a filter media assembly is arranged in the water filtration holes 14. A clear water tank 4 is installed below the water filtration tank 12 at the bottommost part, and the water outlet of the water filtration tank 12 at the bottommost part is connected to the chemical dosing tank 6. The multi-stage water filtration assembly 3 adopts a structure in which a plurality of water filtration tanks 12 are connected end to end and are arranged in sequence from top to bottom. While the sewage flows on the water filtration tanks 12, it is filtered by the filter media assembly in the water filtration holes 14. Among them, the slope of the water filtration tanks 12 at odd positions is 3%, and the slope of the water filtration tanks 12 at even positions is 2%. The water filtration tanks adopt two slopes, which can adjust the flow rate of the sewage, thereby improving the sewage filtration effect. At the same time, the water filtration holes are located in the upper half of the water filtration tank 12, and the water filtration holes on the water filtration tank 12 at the bottommost part cover the entire water filtration tank. In this way, after the sewage passes through the position of the water filtration holes, the flow rate can be accelerated, and when it enters the next layer of water filtration tank, it has sufficient kinetic energy. The filter media assembly includes a storage cylinder 16, a movable orifice plate 17, and a fixed orifice plate 18. The bottom of the storage cylinder 16 is fixed with the fixed orifice plate 18, the top of the storage cylinder 16 is provided with the movable orifice plate 17, the storage cylinder 16 is threadedly connected in the water filtration hole 14, a circular retaining ring 19 is provided at the top of the water filtration hole 14, and correspondingly, a circular clamping groove 20 is provided on the circumference of the movable orifice plate 17. The storage cylinder 16 is filled with filter media. The filter media assembly adopts a combined structure and can be freely replaced, disassembled, and assembled, which is convenient for later maintenance.

[0018] As Figure 5As shown in the figure, the chemical dosing tank includes an outer housing 21, an inner housing 22 and a stirring shaft 23. The stirring shaft 23 is installed inside the inner housing 22. A stirring motor 24 is installed at the top of the inner housing 22. The stirring shaft 23 is connected to the output shaft of the stirring motor 24. The outer housing 21 is installed outside the inner housing 22, and the bottom of the inner housing 22 is open. An overflow channel 25 is provided between the outer housing 21 and the inner housing 22. An overflow port 26 is provided on the outer housing 21. The outer housing 21 and the inner housing 22 are connected and fixed by an annular connecting plate 15. A chemical dosing pipe 2 is also provided on the inner housing 22. The chemical dosing tank adopts a double-layer structure. The inner housing 22 stirs the sewage through the stirring shaft 23 to make the sewage and the chemical agent mix evenly. The mixed sewage is filtered again in the filter tank 7 through the overflow channel 25.

[0019] The above are only the preferred embodiments of the present invention, and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principles of the present invention should be included within the scope of the present invention.
