摘　　要：本文以棉纺织印染废水为主要研究对象，采用无机高分子絮凝剂ＰＡＣ与有机高分子絮凝剂ＰＡＡ复配使用，对印染废水、二硝基重氮酚（Ｄ．Ｄ．Ｎ．Ｐ）起爆药废水、造纸中段水及呋吗醋酮制药废水等进行脱色实验。试验结果表明：ＰＡＣ与ＰＡＡ的复配使用对印染废水具有优良的脱色性能，色度去除率达８０％以上，ＣＯＤ可降低２０～３０％。所用絮凝剂对这几种有色废水具有一定的广谱脱色性能，有较好的工业应用潜力。A study on printing and dyeing wastewater of cotton textile industry,adopting the method of inorganic high polymer flocculent PAC matching organic high polymer flocculent PAA is presentedAnd some decolouring experiments are also conducted with other painting wastewater,for example,wastewater of explosive (DDNP)processing pulping wastewater and pharmceutical wastewaterThe results indicate the effect of PAC matching PAA is excellent in decoloring printing and dyeing wastewater.The removal rate of color is above 80%,and the removal rate of COD is 20～30%Furthermore,the method has a wide use on other painting wastewaterIt provides a potential use in industrial wastewater treatment
