The stones and metal objects remaining on the surface of the vibrating screen 105 fall into the charging box 103 through the discharge end 102 on the surface of the inclined vibrating screen 105 under the action of their own weight, so as to avoid the influence of stones, metal objects, etc. on the subsequent operations. Then, with the cooperation of the conveying pipe 30, it is transported to the deodorizing box 31, and the deodorizing box 31 is used to remove the mud. After the biological strain biological deodorant in the part has deodorized the extracted sludge, it is transported to the grinding box 321, and the centrifugal pump is started at the same time, so that the sludge conditioner inside the liquid medicine tank 4 is transported to the grinding component 32 with the cooperation of the pipeline 36, so that it can be ground evenly, so that the surface load of the sludge can be better reduced in the subsequent filter press component 33, and the specific surface area of ​​the sludge surface can be reduced, so that the water output of the filter press is increased, and the water content of the sludge after the filter press is guaranteed. At the same time, the first rotating motor 322 is started, and the grinding plate group 323 is driven to form a twisted rotation operation with the cooperation of the rotating shaft, so that the sludge can be more fully and evenly mixed with the sludge conditioner liquid, and the water plants and small particle lumps carried in the sludge are fully ground and transported to the filter press box 330.Then, the second rotating motor 332 is started, so that the second rotating motor 332 drives the gear to rotate and meshes with the gear under the partition plate 334, so that the shaft drives the filter roller 333 to filter the sludge on the surface of the partition plate 334 under the separation effect of the partition plate 334, and then the conveyor belt structure 35 is used to shape the filtered sludge and discharge it from the discharge trough 7, and the filtered water falls into the trapezoidal drainage bin 37 with the cooperation of the water leakage net 34, and then the clean water pump 24 is started to operate the filtered water in the trapezoidal drainage bin 37, and then it is transported to the molecular sieve filtration chamber from the pump port on the other side. Under the adsorption effect of the molecular sieve inside the molecular sieve filtration chamber, the filtered water is adsorbed, bonded, and filtered, so that the filtered water is purified and then re-transported to the inside of the river through the drainage pipe 25, the quick connector 27 and the docking pipe 28.
