摘　　要：以粉煤灰固定化絮凝剂填充成絮凝过滤床 ,并组合成连续 -鼓气式五级絮凝过滤床污水处理系统。在吸附、絮凝、沉降、过滤和降解等协同作用下 ,污水流量为 2 5 L/h、鼓气量为 5 0 L/( L· h)、级数为 5时 ,处理水的悬浮物、色度、COD、氨氮、硫化物和苯胺的去除率分别为 99.0 %、91.8%、96.9%、95 %、96.9%、90 .6% ,p H=6.2～ 6.9,基本达到纺织染整工业污水A system of treatment for dyeing and finishing wastewater were combined by five-series beds filled with fly-ash-made immobilized agglomerating agent and controlling-air-through. Adsorbing, precipitating, agglomerating, filtering and decomposing were commonly operated in the system. With flow rate of 25 L/h for dyeing and finishing wastewater and flow volume of 50 L/(L·h) for air in the system, values of the chemical oxygen demand(COD), suspended substances, sulfide, color density, ammoniated nitrogen and aniline in the dyeing and finishing wastewater were cut down by 96.9%,99.0%,96.9%,91.8%,95%,90.6%,respectively,and the range of pH of the treated wastewater was from 6.2 to 6.9,most of which were better than level Ⅱfor dyeing and finishing wastewater promulgated by GB 4287-92.\;
