To discuss the problem of excess sludge reduction, ozonation was used to treat sludge from aerotank.we studied influences to effluent COD、 NH3-N and TP by excess sludge reduction. 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… CONTINUE READING
