The supplementary aeration could effectively control the ratio of anaerobic and aerobic zones in the UFCW reactor. The results clearly show the supplementary aeration boosted the biodegradation of organic pollutants and mineralization of intermediate aromatic amines formed by AO7 degradation.展开更多

The supplementary aeration could effectively control the ratio of anaerobic and aerobic zones in the UFCW reactor.
