摘　　要：以厌氧折流(ABR)反应器中培育的厌氧颗粒污泥为对象,保持颗粒污泥COD负荷为4 kg.m-3d-1,研究SO42-浓度对厌氧颗粒污泥活性的影响。实验结果表明:SO42-浓度在3000 mg.L-1以下时,SO42-浓度的增加对颗粒污泥活性表现为一定的促进作用,促进作用随SO42-浓度增加而增大,SO42-浓度在3000 mg.L-1以上时,SO42-浓度的增加对颗粒污泥活性开始产生抑制作用,抑制作用随SO42-浓度增加迅速增加。The effect of SO4^2-concentrations on the performance of anaerobic granular sludge were investigated using batch experiments with the sludge obtained from an operating anaerobic baffled reactor（ABR）. The experimental results indicated that, when the COD loading rate of granular sludge was 4 kg·m^3 d^-1, the SO4^2- concentration was below 3000 mg·L^-1, SO4^2- has stimulation effect on activity of anaerobic granular sludge, but when the SO4^2- concentration was above 3000 mg·L^-1 ,SO4^2- came into being inhibitive effect, and had more inhibition along with the SO4^2- concentration increasing.
