- Abstract:
- A pilot plant that combined hydrolytic acidification tank, multi-stage A/O biological system, denitrification biofilter, ozone contact oxidation tank and activated carbon filter was designed and developed aiming at limiting nitrogen and phosphorus removal of urban sewage in southern towns. Through 45 days of continuous operation, the process could achieve the goal of removing limiting nitrogen and phosphorus in urban sewage by adjusting the operational parameters, and the TN, TP and COD in the effluent were no more than 3 mg/L, 0.1 mg/L and 30 mg/L, respectively.
