本文研究用四种无机混凝剂处理直接染料和还原染料废水的脱色效果，探讨混凝剂种类加入量和体系pH值对脱色效果的影响。实验结果表明：混凝剂PAC和Al2(SO4)3处理这四种废水，废水脱色率均能达90 %以上；其中混凝剂PAC处理效果最好，不仅用量少，适应pH范围也很广，对于还原橄榄绿B染料废水，其脱色率更高达97.22 %。

In this paper, with four direct dye and inorganic coagulant treatment of waste water vat dyes decolorization effect on the amount and type of coagulant system pH on the effects of decolorizing. The results showed that: coagulant PAC and Al2 (SO4) 3 four waste water treatment, waste water can decolorization rate of 90 percent or more of these PAC coagulant treatment of the best, not only with less, to pH range is broad, The reduction olive green dye wastewater B, the discoloration rate as high as 97.22 percent.
