In order to obtain the more suitable electron acceptor of denitrification phosphorus removal craft,in anaerobic /anoxic conditions,respective ly use NO3-and NO2-,two kinds ofelectron acceptors,to carry on the static contrast experimental study in sequencing batch Reactor activated sludge process(SBR),and inspect the different characteristics of denitrification phosphorus removal.

The denitrifying phosphorous removal process,the simultaneous removal of nitrogen and phosphorous that can be achieved by using the same substrate,is a method with practical prospect for municipal sewage treatment.

The effect of anaerobic HRT(hydraulic retention time) on A2N(anaerobic/anoxic/nitrification) denitrifying phosphorous removal process was investigated by applying a continuous flow,dual-sludge anaerobic/anoxic/nitrification process in practical domestic wastewater treatment.

Compare with conventional denitrifying phosphorous removal process, the combination process of nitrosification / denitrifying phosphorous accumulation and short-cut nitrification can save more energy and reduce sludge discharge, which has important theoretical meaning and application value.
