以硫酸铝渣为原料，研制出了一系列不同A1／Fe／Si物质的量比的聚硅酸铝铁絮凝剂（简称PAFsc）。考察了PAFSC的混凝、除浊、脱色等性能，并研究了A1／Fe／Si物质的量比、pH、投药量等因素对PAFSC性能的影响。处理模拟浊水时，当n（A1）／n（Fe）=2．0～4．0，n（M）／n（SiO2）=0．7～1．3时，除浊率达80％以上；处理模拟印染废水时，在废水pH=7～9，絮凝剂用量为1．5mL／L时，脱色率可达80％以上；处理工业印染废水时，当聚硅酸铝铁n（M）／n（Si02）=1，n（A1）／n（Fe=2．0～3．0时，脱色率达90％左右。

The polysilic aluminum ferric flocculants were prepared from bauxite sledge. Its flocculating effects were studied by coagulating test. The properties of the flocculant, including color removal rate and turbidity removal rate were discussed. The effect of A1/Fe/Si, pH and the dosage were presented. The turbidity removal rate was above 80% in n（A1）/n（Fe）=2.0-4.0, n（M）/n（Si02）=0.7- 1.3 for treatment of the mould turbidity water. The decolorization rate was above 80% in condition that the pH was 7-9 and flocculant was 1.5 mL/L for treatment of the simulated dyingwaste water. During the n（M）/n（SiO2）= 1, n（A1）/n（Fe）=2.0-3.0 in the polysilic aluminum ferric flocculants, the decolorization rate reached 90% for treatment of the industrial dyingwaste water.
