摘　　要：在论述中国偏远社区污水乱排的基础上,采用生物电化学厌氧技术处理河道中沉积已久的污水,实验中通过控制不同的温度、pH、催化剂浓度探讨污水N元素迁移转化规律,结果表明:污水中TN的去除主要是通过氨氮转化为硝氮而实现,温度、pH、催化剂浓度的提高均能使总氮含量有所降低,而硝氮浓度分别为先增后减、递减、递增,外界条件的变化对氨氮的去除影响较小,当控制反应温度为225℃、pH值为7、催化剂浓度为10mg/L时脱氮效果明显。This paper discusses the use of bio-electrochemical anaerobic technology to treat long-distanced river sewage on the basis of discussing the sewage disposing in remote communities in China.In the experiment,the migration and transformation of N elements in sewage is discussed by controlling different temperatures,p H and catalyst concentrations.The results show that the removal of TN in waste water is mainly achieved by conversion of ammonia nitrogen to nitrate nitrogen,and the increase in temperature,p H,and catalyst concentration can reduce the total nitrogen content.The nitrate nitrogen concentration increases first,then decreases.The change of external conditions has little effect on the removal of ammonia nitrogen.When the control reaction temperature is 2250 C,the p H value is 7,and the catalyst concentration is 10 mg/L.The denitrification effect is obvious.
