A/O-MBR was conducted to treat simulated sewage and domestic sewage in this paper, and degradation of pollutants in reactor was studied at the same time. The results showed that the process had excellent removal efficiency of pollutants, under the conditions of C/N was 8:1~10:1, MLSS was 5~9g/L, HRT of part A was 3.93h, HRT of part O was 5.5h, DO of part A was 0~0.5mg/L, DO of part O was 1~3mg/L....
Laboratory scale experiments were conducted to compare the removal efficiency of nitrogen, phosphorus and CODcr in simulated domestic wastewater using two sequencing batch membrane bioreactors (SBMBR) operated in anaerobic aerobic (AO) and anaerobic aerobic anoxic (AOA) mode. And the changing concentrations of different stages in two modes were detected through sequencing cycle test. Results obtained...
