Study on the operational effect of dynamic membrane bioreactor and membrane bioreactor for aquaculture wastewater treatment
摘要
Abstract
Dynamic membrane bioreactor(DMBR) and membrane bioreactor(MBR) were used to treat aquaculture wastewater.The results showed that the CODMn removal rates by DMBR and MBR for treating aquaculture wastewater achieved above 95%.TN removal rates by DMBR and MBR were 71.4%,75.8%,when DO was 0—1 mg/L.When DO was 2—3 mg/L,TN removal rates by DMBR and MBR were 46.3% and 44.1% respectively.DMBR and MBR had high contaminant removal efficiencies.Trans-membrane pressure(TMP) of MBR was much higher than the TMP of DMBR.The operation time of MBR was 5 days when the DO was 0—1 mg/L.The effluent of DMBR depended on gravity,therefore the TMP was 3.97 kPa,and the operation time of DMBR could reach about 10 days.The results showed DMBR can effectively overcome some defects of MBR,such as high membrane cost and fouling.关键词
