In this embodiment, the device further includes a second filtering tank 12, a deodorizing tank 13 and a disinfecting tank 14, the filtering tank 10, the sedimentation tank 11, the second filtering tank 12, the deodorizing tank 13, the disinfecting tank 14 and the adjusting tank 15 are connected in sequence, a backflow mechanism 20 is arranged on each tank 100, and a detector 160 is arranged on the fixing pipe 120 at the water outlet end. And if the water quality of the sewage flowing out from each process is unqualified after detection, the sewage flows back to the water inlet end from the branch pipe 200 for secondary treatment, and the qualified sewage can flow into the next process until the treatment is finished. In this embodiment, all inner walls of the tank 100 are made of corrosion-proof, rust-proof and water-proof materials.

Specifically, as shown in fig. 4 and 5, a support frame 180 and a screen 181 are disposed in each of the filtration tank 10 and the second filtration tank 12, the support frame 180 is circumferentially disposed on the inner wall of the tank body 100, the screen 181 is disposed in the support frame 180, and the mesh of the screen 181 in the second filtration tank 12 is smaller than the mesh 181 in the filtration tank 10. The sedimentation tank 11 is a hopper-shaped, the fixing pipe 120 is arranged at the top, the top is provided with a feeding opening, and the bottom is provided with a sludge discharge pipe 170.

After sewage enters the filtering tank 10, the screen 181 can intercept relatively coarse floating objects and suspended matters, and then the heavy solid substances are separated from water after sinking in the settling tank 11 after entering the settling tank 11, a flocculating agent can be added from a feeding port at the top to accelerate solid-liquid separation, the sewage flows into the second filtering tank 12 from the fixed pipe 120 at the top, and the solid sediments are discharged from the sludge discharge pipe 170 at the bottom. The second filtering tank 12 performs secondary filtering on the sewage to prevent floc and the like from flowing in.
