Described air line comprises gas blower, and described gas blower connects respectively described equalizing tank and contact-oxidation pool by tracheae;
Described mud pipeline comprises sludge thickener and plate-and-frame filter press, described coagulation basin, contact-oxidation pool, two-stage coagulation air flotation pool and second pond are respectively by sludge thickener described in pipeline connection, and described sludge thickener enters described plate-and-frame filter press by pipeline connection air diaphragms pump;
Described sludge thickener and plate-and-frame filter press are communicated with described equalizing tank by described supernatant liquor filtrate return wire respectively.
Also comprise middle water secondary treatment system, described middle water secondary treatment system is: described middle water reuse tank is communicated with tube settler, inspection pond, lift pump, filtration tank, sandstone filtration recoil pond, clean water basin and pump house successively by pipeline; Described sandstone filters recoil pond by equalizing tank described in pipeline connection.
In the utility model, Sewage treatment systems has improved the processing power of waste water, rationally distributed, and level of automation is high, is easy to management; Surplus sludge volume is few, saves processing cost, reduces and pollutes.Middle water secondary treatment system, adopts the techniques such as tube settling, quartz sand filtration and activity carbon filtering device, on original middle water reuse facility basis, makes reuse water through filtration treatment → precipitation process, makes water quality reach printing and dyeing water quality requirement, and the energy economizes on resources.The utility model, by the transformation to former intermediate water reuse system, has improved the utilization ratio of reuse water, has protected water resources.
