Modified Step-feed A/O Biological Nitrogen Removal Process for Enhanced Phosphorus Removal
改进分段进水A/O生物脱氮工艺强化生物除磷

A pilot-scale step-feed A/O system was used to treat low C/N municipal wastewater.To obtain high quality simultaneous nitrogen and phosphorus removal, a modified step-feed A/O system was developed and the nitrogen and phosphorus removal efficiency was evaluated between the original and modified system.The result showed that TN removal efficiency was 66.52% and TP removal efficiency was only 29.24% before the modified configuration was applied.When the modified system was adopted,the satisfied simultaneous n...
