Effect of SRT on Nitrogen and Phosphorus Removal in Modified Carrousel Oxidation Ditch Process

Abstract:

Based on a modified Carrousel oxidation ditch process acclimated with synthetic wastewater，effect of SRT on nitrogen and phosphorus removal occurred in the system was investigated. The results indicated that SRT was prominent to nitrogen and phosphorus removal. The removal efficiency of nitrogen was better with SRT extension and that the removal efficiency of phosphorus was better with SRT shortness. With the operation conditions of water temperature 30°C, SRT 11days, the removal efficiency of TN and TP reached 85.4% and 74.9%, which indicated that nitrogen and phosphorus removals were best.
