[0030] Example
[0031] figure 1 A membrane bioreactor with a stainless steel wire mesh fine filtration assembly is shown.
[0032] After rough filtration and initial precipitation, the sewage is pumped into the bioreactor 2. The liquid level of the sewage is monitored by the liquid level gauge 18, and the signal is transmitted to the PLC control cabinet to control the opening and closing of the sewage pump and the inlet 1. The aeration system of the biochemical tank consists of a fan 13 , an air valve 14 , an air flow meter 15 and an aerator 17 . The flow of air is regulated by PLC-controlled air valve 14 . The stainless steel wire mesh fine filter assembly 3 is connected to the water outlet system. The water outlet system consists of a water outlet pressure gauge 4, a water outlet valve 5, an outlet water pump 6 and an outlet water flow meter 7. The effluent flow meter transmits the signal to the PLC control system, and the outflow water (150-200L / m) is maintained by a...
