摘　　要：采用生物预处理+常规与常规工艺处理西江微污染原水,对主要污染物的去除效果工艺进行了比较。结果表明,生物预处理+常规工艺对氨氮、CODMn的平均去除率达57.6%、47.1%,比常规工艺提高了34.7、17.1个百分点。生物预处理强化了混凝效果,能节省约20%的絮凝剂。高速给水曝气生物滤池的工程投资约100～130元·m-3,运行费用0.03～0.05元·m-3。Biological pre-treatment/eonventional treatment and conventional treatment were used to treat Xijiang micro-polluted source water, and the removal effieiencies of main pollutants was compared. The average removal rates of NH3-N and CODMn by biological pre-treatment/conventional treatment were 57.6% and 47.1% ,which increased by 34.7% and 17.1% than conventional treatment.Coagulation was intensified by biological pretreatment and about 20% of the coagulant can be saved.The high-rate UBAF investment was about 100 to 130 yuan·m^-3, and the operation cost is about 0.03 to 0.05 yuan·m^-3.
