摘　　要：广州某地沟油回收处理公司的废水处理工艺失效，出水水质严重不达标。在对废水水质、水量进行分析后，根据目前系统存在的问题，充分利用现有的构筑物和设备，提出采用升流式厌氧污泥反应床（UASB）／好氧／曝气生物滤池／Fenton氧化工艺进行改造，经过半年的调试运行，废水COD值由10000～12000mg／L降到90mg／L以下，NH3-N由400mg／L降到10mg／L以下，出水水质满足广东省《水污染物排放限值》（DB44／26--2001）二时段一级标准。The wastewater treatment process of a gutter oil recycling and treatment company in Guangzhou was disabled, and the effluent quality could not meet the standards. Based on the analysis of the wastewater quality, quantity and the problems of the existing system, the modification process using up-flow anaerobic sludge blanket （UASB） , aerobic, biological aerated filter and Fenton oxidation was designed by making use of the existing structures and facilities. After the commissioning and operation for half a year, the concentrations of COD and ammonia nitrogen were reduced from 10 000 - 12 000 mg/L to below 90 mg/L and 400 mg/L to below 10 mg/L respectively. The effluent quality met the first class criteria （the second period） of the Guangdong Province local standard Discharge Limits of Water Pollutants （ DB 44/26 - 2001 ）.
