Sewage through the grating into the regulating pool after the lifting pump into the bioreactor, through the PLC controller to open the aerator oxygenation, bioreactor effluent through the circulating pump into the membrane separation treatment unit, the concentrated water back to the regulating pool, membrane separated water after rapid mixing method of chlorination and disinfection (sodium hypochlorite, bleach, chlorine tablets), into the medium water storage tank. Vertical can be idling pumps use the water in the cleaning pool to backwash the membrane treatment equipment, backwash sewage returned to the regulating pool. Through the water level in the bioreactor to control the opening and closing of the lifting pump. When the produced water needs chemical cleaning operation, close the water inlet valve and sewage circulation valve, open the medicinal washing valve and pharmaceutical circulation valve, start the medicinal liquid circulation pump, chemical cleaning operation.
In the membrane biological reaction of the entire process used in the mbr special suction pumps have self-priming circulating pump. Mabel's self-priming pump is acid and alkali resistant, corrosion resistant, simple structure, easy to install.
