Studies on the Performance of Biofilm-MBR

Abstract:

MBR technology for sewage treatment has the advantages of high volumetric load, good treatment performance and so on. But the MBR technology also has the shortage of membrane fouling. So this study selected the control method of fixing combination packing added in the MBR reactor, so as to reduce the membrane pollution, at the same time in the reactor to create the environment of coexistence of anaerobic and aerobic for biological denitrification. Through the research of the pollutants removal efficiency and the membrane pollution, it was founded that this method can remove 85-95% of COD and ammonia nitrogen. Effluent COD concentration generally is about 25mg/L, and the minimum of it is less than 10 mg/L. Effluent ammonia nitrogen is generally less than 10 mg/L. The minimum effluent concentration of ammonia nitrogen was less than 1 mg/L. The removal rate of total phosphorus was between 30-45%.
