There are many sewage treatment processes used at home and abroad, mainly divided into activated sludge method and biofilm method. Our common general aeration method, oxidation ditch method, A/B method, and A2/O method belong to the former, and the biological turntable and contact oxidation method belong to the latter. The integrated sewage treatment equipment integrates one sink, grade I, II contact oxidation tank, two sink tank and sludge tank, and performs blast aeration in the I and II contact oxidation tanks, so that the contact oxidation method and the activated sludge method are effectively combined, and the advantages of both are overcome, and the sewage treatment level is further improved.
