摘　　要：城市污水强化一级处理工艺——高负荷活性污泥法(HAS)具有不设初次沉淀池,负荷高,泥龄短,污泥沉降性能良好,不存在污泥膨胀等特点,对有机物的去除以絮凝、吸附、沉淀作用为主,对COD、BOD5、SS都有较高的去除效果,对氮、磷有一定的去除作用,出水水质可满足《农田灌溉水质标准》的要求;此工艺是解决经济欠发达地区水资源短缺和水污染严重的一种最佳方法。High-load activated sludge （ HAS ） process, as a process for enhanced primary treatment of municipal waste- water, has such merits as no primary sedimentation basin, high-load, low resident time, good sludge-settlement ability, no sludge swell. The mechanism of HAS process removing the pollutant is mainly of flocculation, adsorption and precipitation. The removing rates on COD, BOD, SS, so do nitrogen and phosphorus are higher. The effluent can meet 《Standards for Irrigation Water Quality》 . HAS process is the best measure to solve the questions of lack of water resource and serious water pollution in undeveloped area.
