Abstract

In order to investigate disposal efficiency of campus wastewater by using biological aerated filters( BAF) and effective microorganism biological aerated filters( EMBAF) processes,two parallelled operated BAF processes are carried out under the same operating conditions. The results show that: the average removal rate of EMBAF for chemical oxygen demand( COD) and ammonia( NH4+-N) can reach 90. 7% and 81. 6%,increasing by 13. 4% and 15. 7% than BAF's. Compared to BAF,EMBAF can stabilize the total phosphorus( TP) of the effluent.
