Abstract

Abstract: A new process-high-load activated sludge (HAS) process is reported for the treatment of municipal wastewater in medium and small cities. The marked characteristics of HAS process are no primary sedimentation basin, high-load, low resident time, good sludge-settlement ability, and no sludge swell. The removing methods of the organic pollutants are mainly of flocculation, adsorption and precipitation. The full-scale test results show that the average removal efficiency of the process is 68% for COD, 65% for BOD5, 86% for SS, 24% for TKN, 20% for TP. The effluent can meet "Standards for Irrigation Water Quality"（GB5084-92）. HAS process can reduce investment, operating cost and area.

Key words: High-load activated sludge process, Municipal wastewater, Enhanced primary treatment, Flocculation, Adsorption

摘要： 对适合中小城市污水处理的工艺-高负荷活性污泥法进行了中试。该工艺显著特点是不设初次沉淀池，负荷高，泥龄短，污泥沉降性能良好，不存在污泥膨胀，对有机物的去除以絮凝、吸附、沉淀作用为主。试验表明，高负荷活性污泥系统对COD平均去除率达68％、BOD5去除率达65％,SS去除率达86％，凯氏氮去除率达24％，总磷去除率达20％，出水各项指标均可满足《农田灌溉水质标准》（GB5084-92）的要求。高负荷活性污泥法还具有基建投资和运行费用低、占地面积少的特点。
