The efficiency of several common biochemical wastewater treatment technologies were investigated,compared and analyzed by mean of treating sanitary wastewater.The Biological Aerated Filter Process(BAF),Anaerobic-anoxic-oxic Process(A2/O),Sequencing Batch Reactor Activated Sludge Process(SBR),and Membrane Bio-Reactor Process(MBR)were carried out to treat living wastewater from the water treatment station in school for reclaimed water.The treatment results displayed that all of those methods could treat the l...
