HU Chunling1,FU Qiang2,ZHANG Jing1,WEI Dongyang3,QIU Rongchu4(1.School of Environmental and Biological Engineering,Liaoning Shihua University,Fushun 113001;2.Fushun Water Supply Engineering Design & Research Institute,Fushun 113008;3.School of Environmental Science and Engineering,Zhongshan University,Guangzhou 510275;4.School of Environmental and Municipal Engineering,Lanzhoujiaotong University,Lanzhou 730070)  
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 precipi-tation.The removing rates on COD,BOD,SS,so do nitrogen and phosphorus are higher.The effluent can meet 《Stan-dards 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.
