The results show that the removal efficiencies of CODcr, BOD5, NH3 - N and chromaticity can respectively reach 87 % to 94 % , 94% to 98%, 91% to 94% and 91% to 93% depending on the control parameters of operation. All the water quality parameter of effluent meets the Government Drainage Standard.展开更多
