摘　　要：开展了生物接触氧化/气浮工艺处理微污染源水的中试研究(规模为20 m3/h),考察了生物接触氧化池的气水比、水力停留时间、悬浮生物填料填充率和气浮池混凝剂投加量、表面负荷对污染物去除效果的影响。结果表明,当生物接触氧化池的气水比为1.0、水力停留时间为60m in、填料填充率为40%与气浮池的硫酸铝投加量为30 mg/L、表面负荷为7.5 m3/(m2.h)时,工艺除污效果良好,对CODMn的去除率为23%,出水NH3-N及TP达到了地表水Ⅱ类水水质标准。A pilot-scale test with influx of 20 m^3/h based on biological contact oxidation/air flotation process was carried out for treating micro-polluted source water. The influence of air-water ratio, HRT（ hydraulic retention time）, media-filling rate for biological contact oxidation tank and dosage of flocculating agent, surface loading for flotation tank on pollutants removal was studied. The results show that when the air-water ratio is 1.0, HRT is 60 rain, media-filling rate is 40% , the dosage of flocculating agent is 30 mg/L and surface loading is 7.5 m^3/（m^2· h）, pollutants removal effects are excellent with removal rate for CODMn, which can be up to 23% , its effluent NH3 - N and TP can achieve standards for Ⅱ-class criteria of surface water.
