Further, in this embodiment, the secondary separation device 5 is a stacked screw sludge dewatering machine. Specifically, the stacked screw sludge dewatering machine adopts the form of stacked screw extrusion. On the one hand, the solid-liquid separation of various feces treated with flocculants can not only solve the problem of sedimentation, enhance the processing capacity, but also greatly reduce The construction area of the biochemical pool, at the same time, the treated sewage will not block the municipal pipeline, meet the third-level discharge standard of septic tank sewage, and save the construction investment and land use area of environmental protection treatment to the greatest extent. On the other hand, for all kinds of feces themselves, the solid matter obtained by extrusion treatment is almost odorless, less viscous, and the garbage is automatically separated, which is convenient for disposal. At present, the more common sludge separation technology usually adopts decanter centrifuge, plate and frame filter press, belt filter press, etc. Compared with the stacked screw sludge separator, the decanter centrifuge has high mechanical requirements and high performance. The consumption and investment cost are relatively large, and the speed is as high as 5000 rpm or more; the plate and frame filter press has small processing capacity, cumbersome operation, and the filter cloth is easy to be damaged and blocked, and is generally only suitable for small sewage stations; belt filter press There are also shortcomings such as large floor area, high energy consumption, and large amount of flushing water. The stacked screw sludge dewatering machine not only successfully overcomes the shortcomings of the above types of machines, but also has many advantages such as small size, light weight, small vibration, low noise, no pollution, continuous use, and no need for personnel to be stationed.

The process of using the above-mentioned sewage treatment system for sewage treatment is as follows:

After the sewage enters the crushing equipment 1 for sewage treatment, it is aerated, stirred and crushed and enters the primary separation equipment 2. The crushed sewage is rotated and filtered in the primary separation equipment 2 along with the rotating filter cylinder. Among them, the larger dirt is automatically discharged from the inside of the drum 21 of the rotary filter drum, and the sewage containing smaller dirt enters the rotary filter through the sieve holes of the drum 21 and the filter screen 22 from the inside of the drum 21 of the rotary filter drum. The outside of the filter screen 22 of the screen cylinder, the sewage that contains the relatively small dirt outside the filter screen 22 of the rotary screen cylinder is collected (collecting containers such as collecting tanks can be used) and then flows into the mixing box 4, and the mixing box 4 also receives from The flocculant in the flocculant dosing box 3, the above flocculant and the sewage containing small dirt are flocculated in the mixing tank 4 to form flocs, and the formed flocs and sewage flow into the secondary separation from the outlet of the mixing tank 4 Equipment 5, the secondary separation equipment 5 receives the sewage containing flocs from the mixing tank 4 and separates it into sewage and dried solid waste.

Therefore, the sewage and feces treatment system of the utility model has the advantages of automatic sewage and feces suction, aeration, agitation, and smashing of sewage and feces, and the advantages that the pipeline is not easy to be blocked.
