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CODMn、氨氮的平均去除率达48.9%、62.3%,比常规工艺提高了18.9%、28.4%。2种工艺对浊度的去除率相当,皆为95%左右。生物预处理采用高速给水曝气生物滤池工艺,反冲洗采用气水联合方式,48 h过滤水头损失<2 kPa,冲洗前后过滤水头损失变化量均值<0.4 kPa。Biological pre-treatment with conventional treatment and the solely conventional treatment were applied to treat Xijiang micro-polluted source water.The removal efficiencies of main pollutants were compared.The average removal rates of CODMn and NH3-N of biological pre-treatment with conventional treatment were 48.9% and 62.3%,respectively,which increased by 18.9% and 28.4% than that of solely conventional treatment.The removal rates of turbidity were both about 95%.The technology of high-rate upflow biological aerated filter（UBAF）with air-water backwash pattern was used in biological pre-treatment.The head loss was less than 2 kPa after 48 hours filtration,and the variable quantity of filtering head loss was less than 0.4 kPa after backwash.
