摘　　要：液体化学品废水有毒有害物质多,水质波动大。采用隔油气浮/曝气生物滤池蠕动床/臭氧氧化/曝气生物滤池固定床组合工艺进行处理,COD由进水的1 200 mg/L左右降到100mg/L以下,SS由进水的600 mg/L左右降到30 mg/L以下,出水水质达到《污水综合排放标准》(GB 8978—1996)的一级标准,可回用作生活杂用水。实际运行结果表明,该组合工艺有效、稳定,污泥产量少,可操作性强,有很好的环境效益和经济效益。Liquid chemicals wastewater contains toxic and harmful substances, and the wastewater quality changes greatly. The combined process of oil separation and floatation, biological aerated filter （BAF） peristalsis bed, ozone oxidation and BAF fixed bed was used to treat this wastewater. The COD and SS are decreased from 1 200 mg/L to below 100 mg/L and from 600 mg/L to below 30 mg/L. The effluent quality reaches the first level criteria specified in the Integrated Wastewater Discharge Standard （GB 8978 -1996）, and it can be applied as domestic miscellaneous water. The practical operation shows that the combined process is efficient, stable and easy in operation, and produces little sludge. It has significant environmental and economic benefits.
