Removal characteristics of pollutants in airlift intermittent circulation membrane bioreactor
An airlift intermittent circulation mebrane bioreactor was developed for simultaneous nitrogen and phosphorus removal of wastewater,in which,circulation of mixed liquid between anaerobic zone and oxic zone was realized by aeration power,intermittent anaerobic/anoxic bio-environment in anaerobic zone was realized by intermittent circulation and simultaneous nitrogen and phosphorus removal was obtained through strengthened denitrifying phosphorus removal process.Pollutant removal and transfer mechanism in one operation circle was analyzed.The experiment results indicated that the separation of distinct biological environments specially and temporally,which ensured the requirement of different microorganisms and the occurrence of bio reaction.Nitrogen and phosphorus removal was realized through the processes of convention nitrification-denitrification,SND,anaerobic phosphorus release and oxic-absorption and denitrifying phosphorus removal.
