Study on the Influence of Phosphorus Removal Effect and Membrane Fouling by Adding Aluminum Salt to A/O-MBR

This paper used A/O-MBR wastewater treatment system,which was the combination of membrane technology and the A/O treatment process, which took experiments on the campus sewage, the study was made on the influence of phosphorus removal effect and membrane fouling by adding aluminum salt to the system. The result implied that the phosphorus removal effect of the system was improved significantly after adding aluminum salt. Observation was also taken on when TMP reached the limit value in A/O-MBR system and Al2(SO4)3-A/O-MBR system respectively, which showed that the stable operation time of the reactor that added Al2(SO4)3 was longer.

Wastewater Treatment System

To meet the more strict discharging standard, some combined processes have emerged to realize denitrification and phosphorus removal of wastewater more efficiently. Among them, AAO-BAF combined process was an efficient one. The AAO-BAF system was composed of AAO reactor and BAF. The AAO process was the main unit to complete phosphorus removal and denitrification. The BAF process, external nitrification unit, was mainly used to provide enough electron acceptor for denitrifying bacteria in AAO reactor, which could enhance the efficiency of denitrification of the whole system. So the system optimizing was essential to AAO-BAF combined process. In this paper, the research progress of AAO-BAF wastewater treatment system was summarized and some system optimizing methods were raised too.
