摘　　要：结合贵州山区具有地势落差的地形条件，设计了“跌水生物接触氧化＋氧化塘”的工艺处理方式处理农村生活污水，通过对处理装置3~5月的监测表明，CODcr、TN、TP的出水平均浓度为42、4.0和0.41 mg/L，平均去除率分别为79%、69%、78%。出水水质可达到《城镇污水处理厂污染物排放标准》（GB 18918-2002）一级排放标准，依靠地势落差实现无动力消耗运转。Considering conditions of Guizhou mountain region, the “waterfall aeration contact oxidation ＋oxidation pond” process of the treatment of rural domestic sewage was designed. Monitoring the processing plant from March to May showed that the average concentrations of CODcr,TN and TP in the water outlet were 42,4.0 and 0.41 mg/L, respectively. The average re-moval rate of CODcr, TN and TP reached above 79%, 69%, and 78%, respectively. The water quality reached ClassⅠspec-ified with the standard of Discharge Standards of Pollutants for Municipal Wastewater Treatment Plants （GB 18918-2002）. The process depend on terrain realized the function without power consumption.
