%X This research was on sequencing batch reactor activated sludge system, using 2,6-dichlorophenol as uncoupler with the concentration of 20(mg/L),using Cu~(2 ) with the concentration of 1(mg/L),adding into the SBR activated sludge system.Through 30 days continuously operation,we discovered that the removal efficiencies of COD was 7% lower than the control experiment,and sludge reduction would reach 75%,while the average concentration of 2,6-dichlorophenol was 0.28 (mg/L) in the effluent,and the removal efficiency of Cu~(2 ) was over 90%.But the sludge settleability and the removal efficiencies of nitrogen and phosphorus dropped,as well as sludge activity.According to the microscope examine,we discovered filamentous bacteria in the sludge increased,while quantity and type of protozoon and metazoa reduced.The result indicated that Cu~(2 ) and 2,6-dichlorophenol had the obvious cooperation to the sludge reduction,so using Cu~(2 ) and uncoupler to limit the sludge yield in the activated sludge system was feasible.
