摘　　要：为了考察分散式生活污水处理装置对不同碳氮比污水的处理效果,本文研究了分散式生活污水处理装置对不同碳氮比人工污水和实际生活污水的COD、NH_3-N和TN去除性能。结果发现,该装置处理碳氮比不低于17:1且COD浓度为500 mg/L的人工污水和处理碳氮比为19∶1~6∶1且COD<253.9 mg/L的实际污水时,系统出水COD、NH_3-N、TN均能满足《城镇污水处理厂污染物排放标准》(GB 18918—2002)一级B标准。当处理低COD浓度实际生活污水时,对碳氮比的改变具有良好的适应性。In order to explore the performance of integration decentralized sewage treatment device for the sewage with different carbonnitrogen ratios, the synthetic sewage and actual wastewater were treated by the device, and the removal performance of COD, NH3-N and TN were studied. The results showed that when treating the synthetic sewage with carbon-nitrogen ratio higher than 17：1 and COD concentration of 500mg/L, as well as the actual wastewater with carbon-nitrogen ratio between 19：1 and 6：1 and COD concentration lower than 253.9 mg/L, the effluent＇ s concentration of COD, NH3-N and TN could all meet the Level 1-B Standard of Discharge standard of pollutants for municipal wastewater treatment plant （ GB 18918-2002）. In addition, the device has good adaptability to changes of carbon-nitrogen ratio when treating actual wastewater with low COD concentration.
