3. 20 persons Waste Water Treatment Device System Principle

Sewage first enters into the buffer tank to adopt the biochemical treatment, meantime the tank can contain the sewage 3 times peak load. When the liquid reaches the middle-level, the cutting pump is started and the sewage is transferred to sequence tank with soft stuffing, and then contact oxidizing、biological treatment the sewage. the discharge pump is started and transferred the treated sewage into membrane assembly. The permeated pure water should be disinfected by UV device, then discharged overboard. According to the regulation of IMO, the regulated sea area should adopt the sequence or membrane treatment.
