| 摘 要： | 以聚硅酸铝铁（PSAF）为混凝剂，研究了聚硅酸铝铁处理印染废水的最佳工艺条件，如聚硅酸铝铁投加量、Al／Fe摩尔比、废水酸度。实验结果表明，水样pH为7．5，聚硅酸铝铁Al／Fe摩尔比为4：1，质量浓度为16mg·L^-1时，脱色率可达90％左右。

| Abstract: | Dyeing wastewater treatment by using polysilicate-aluminum-ferric as flocculant was studied. The optim altreatment conditions with the combined flocculant system were investigated, such as flocculant dosage, A1/Fe ratio, acidity of waste water. The results showed that the optimal parameters were polysilicate-aluminum-ferric, dosage of 16 mg·L^-1 and the best pH was 7.5. The best removal of decolorization rate was 90 % . |
