[Process of Enrichment and Culture of PAOs on a Novel Biofilm Process of Dephosphorization]

Using the hanging nylon as a biological carrier,a novel biofilm reactor was adopted to treat synthetic wastewater,and the feasibility of cultivating and enriching a high concentration of PAOs on this conventional biofilm within a short time was investigated,which was proved from the aspects of reactor's operational efficiency,the rate of phosphorus removal and the condition of PAOs enrichment.After 10d of operation,the rate of orthophosphate removal was higher than 95% in aerobic phase and the concentration of effluent COD was 50 mg·L
