摘　　要：以粉煤灰为原料制取絮凝剂PAFCS和改性粉煤灰吸附剂,联合处理苯胺废水.结果表明,投加PAM使去除率得到提高,去除率分别达到COD 60.0%、色度33.3%、浊度98.8%.改性粉煤灰的浓度100g/L时,去除率分别为COD 80.0%、色度93.3%,而浊度增加了约2倍.出水符合"污水综合排放标准"(GB8978-1996)一级排放标准.Flocculant PAFCS and modified fly ash adsorbent were prepared by using fly ash as raw materials, and the treatment of aniline wastewater were investigated. The results showed that the removal rate were improved by the addition of PAM ,the removal rate of COD, chroma and turbidity were achieved 60% ,33.3% and 98.8% ,respectively. When the concentration of Modified fly ash were 100g/L,the removal rate of COD and chroma were 80.0% and 93.3% ,but the turbidity increased about 2 times,which are better than level 1 for integrated wastewater discharge standard by GB8978-1996.
