摘　　要：生物接触氧化工艺是目前较为成熟的水质净化技术,国内外在河流水质净化、水体修复中都有较多的研究和应用。在实验室采用沟渠式生物接触氧化组合系统处理模拟村庄面源污水,较好地去除了有机物并实现氨氮转化。结果表明,当进水COD为130～290mg/L、氨氮为30～40mg/L、水力负荷为0.19～0.24m3/(m2·d)的条件下,该系统稳定运行11周,COD和氨氮的平均去除率分别达85%和79%。As a well developed water purification technology, biological contact oxidization pond has been widely researched and applied in river purification and remediation. Synthetic wastewater simulating village non-point source sewage is effectively purified in a laboratory biological contact oxidization pond system. Steady COD and ammonia nitrogen removal can be achieved at 85% and 79% respectively on the average in 11 weeks, when the concentration of COD and ammonia nitrogen is 130 to 290 mg/L and 30 to 40 mg/L, and the hydraulic loading is 0. 19 to 0.24 m3/（m2· d）.
