Embodiment Construction

[0037] Figure 2 shows the feces treatment method and system of the present invention. The system includes solid-liquid separation equipment, regulating tank reflux mixing system, sewage conveying system and flocculation and dehydration equipment. Firstly, the solid-liquid separation equipment performs solid-liquid separation treatment on the feces; after separation, the feces are discharged into the regulating tank with a reflux stirring system, and the feces in the regulating tank are discharged by the sewage conveying system; The manure is flocculated and dehydrated.

[0038] Figure 3 shows the technical assembly and treatment process of the solid-liquid separation room. As shown in Figure 3, the process room assembly includes a set of excrement discharge port docking device 11, a set of balancing device 12, a deodorizing liquid tank 14, a shaftless screw conveyor 15, and a It consists of a solid-liquid separator 16 for sorting, floating debris crushing, sand removal, and ...

Abstract

The invention discloses a dejecta treating method and system containing following steps: firstly liquid-solid separation processing to the dejecta by liquid-solid separation device; entering the separated dejecta to an adjusting pool with a wind blending system, then discharging the dejecta in adjusting pool by sewage feeding system of underground pump room, then flocculating-dehydrating treatment of transported dejecta from adjusting pool by flocculating-dehydrating apparatus. Setting a wind blending system in the adjusting pool to make the dejecta fluid always in blending state by forming multiple-point shocks, shaking and agitating effectly overcomes the deposition of the loam, stacking and dejecta fluid surface scab. The flocculating injecting medicine mixing process can greatly improve the use life of pump. It achieves the recovery of resource by anaerobic / biochemical treatment of filter solution generated by flocculating-dehydrating treatment. It reduces the secondary pollution and achieves the harmless treatment of dejecta.

Description

technical field [0001] The invention relates to the field of environmental protection, in particular to a method and system for centralized and harmless treatment of feces. Background technique [0002] Disorderly discharge of feces, difficult consumption, and difficult disposal are major problems in the process of urbanization in my country. Figure 1 shows the feces treatment method and system in the prior art. The steps of the treatment method are: first, solid-liquid separation is carried out on the feces. This step is carried out in the solid-liquid separation equipment, and the separated solid debris is sent to the slag discharge. During the period, the separated liquid is discharged into the excrement adjustment tank, and the adjustment tank is used to cache the separated feces, and the effluent is discharged by power, and the feces in the adjustment tank are discharged by the sewage conveying system; then the feces transported by the adjustment tank are flocculated D...
