摘要
选用ＭｇＳＯ＿４作为混凝剂处理高浓度印染废水，并与ＰＡＣ作为混凝剂对比试验．用正交试验确定其处理的最佳条件，再在此条件下处理混合印染废水，研究表明：用ＭｇＳＯ＿４处理废水的最佳ｐＨ值在１２左右，ＣＯＤ＿ｃｒ去除率达８０％以上，脱色率达９０％以上，较ＰＡＣ脱色率和ＣＯＤ去除率高，可望成为处理印染废水的新型混凝剂．
MgSO_4 was selected as coagulant to treat high- concentration dyeing wastes with APC as its contrast.Through orthogonal test,the optimum condition for treatmemt was obtained,and mixed dyeing wastes were treated under such a condition.the study shows that when MgSO_4 is used to deal with the waste water,the best pH value is 12,the rate of removing COD_cr is over 80%, and the decolourization rate is over 90%,which are higher than those of using PAC. Hence MgSO_4 is expected to ha a new type of coagulant in handling dyeing wastes.
