To discuss the problem of excess sludge reduction,ozonation was used to treat sludge from aerotank,and influences to COD、NH_3-N and TP by excess sludge reduction were studied.Test indicated that:specific desaturase activity of excess sludge decreased with oxidation time;in mixture of sludge and water after oxidation,SCOD increased with time extending;the removal rate of COD and TP had no obvious change,and the removal rate of NH_3-N increased a little when access sludge after oxidation was discharged into A...
