Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment, and more specifically to sewage treatment equipment for municipal water supply and drainage. Background Art

[0002] In municipal water supply and drainage projects, in order to ensure that sewage meets standards or is reused, it is usually necessary to treat the sewage. At this time, sewage treatment equipment, namely integrated sewage treatment equipment, is required. Its specific working process is as follows: the sewage first enters the filter tank to filter impurities. The filtered sewage enters the regulating tank and then enters the bioreactor through a lift pump. The aerator is turned on by the PLC controller to oxygenate. The effluent from the bioreactor enters the membrane separation treatment unit through a circulation pump, and the concentrated water returns to the regulating tank. The water separated by the membrane is disinfected by rapid mixing chlorination (sodium hypochlorite, bleaching powder, chlorine tablets) and then enters the reclaimed water storage tank. The backwash pump uses the treated water in the cleaning tank to backwash the membrane treatment equipment, and the backwash sewage returns to the regulating tank. The start and stop of the lift pump is controlled by the water level in the bioreactor. The filtration operation and backwashing operation of the membrane unit can be automatically or manually controlled. When the membrane unit requires chemical cleaning, the water inlet valve and sewage circulation valve are closed, the chemical cleaning valve and the chemical circulation valve are opened, and the liquid circulation pump is started for chemical cleaning.

[0003] In the filter tank of the existing integrated sewage treatment equipment, a grille is usually used to filter impurities in the sewage, and the size of the grille holes is usually fixed. However, during the use of the grille, if the particles in the sewage are large and the grille holes are small, it will cause the grille to be blocked; if the processing flow is large and the grille holes are small, it will also cause the grille to be blocked. In view of this, we propose a sewage treatment equipment for municipal water supply and drainage. Utility Model Content
