摘　　要：用聚合硫酸铝铁为混凝剂,阳离子型聚丙烯酰胺为助凝剂,活性炭为吸附剂,采用混凝吸附的方法,处理了小麦麸膳食纤维废水.结果表明当聚合硫酸铝铁(PAFS)的质量浓度为500 mg/L,聚丙烯酰胺(PAM)的质量浓度为10 mg/L,pH为4.21时,混凝处理后的废水COD去除率最大.絮凝后水样经活性炭吸附后COD去除率可达85.82%,色度去除率为100%,浊度去除率为93.03%.The wastewater of dietary fiber from wheat bran was treated with polyaluminum ferric sulfate （PAFS） as coagulant, cationic polyacrylamide as flocculant and active carbon as absorbant. The results showed that when the concentration of PAFS was 500 mg/L, PAM 10mg/L, and pH value 4.21, the removing rates of COD of the wastewater was the highest. The removing rates of COD, colourity, turbidity was 85.82 %, 100 %, 93.03 % respectively after coagulation and absorbtion by active carhon,
