摘　　要：目的了解农村地区生活污水处理效果。方法于2010年9月对南昌市青云谱区稳定塘和生物化学生活污水处理系统(以下简称"生化处理系统")两种类型的生活污水处理系统的入水和出水水样进行采集和检测。结果经两种类型的生活污水处理系统处理后生活污水的合格率均明显提高;生活污水经过处理后,除pH值明显升高外,色度、总磷、总氮、氨氮、悬浮物、五日生化需氧量和化学需氧量均明显降低,且生化处理系统对7项指标的去除率均高于稳定塘。结论生化处理系统对生活污水的处理效果比稳定塘更明显。Objective To know＇the effect of rural domestic sewage treatment. Methods The sewage samples from the entrance and exit of the two type domestic sewage treatment systems of stability pond and biochemical treatment system in Qingyunpu,Nanehang,Jiangxi province were tested in September 2010. Results The qualified rates of the sewage samples were significantly raised by two types of domestic sewage treatment systems. The colority,total phosphorus,total nitrogen, ammonia nitrogen,suspended substance,BODs and COD in domestic sewage were significantly reduced,and the pH value increased significantly in two types of domestic sewage treatment systems. The removing rates of the former seven indexes by the biochemical treatment system were more than the stability pond. Conclusion The effect of domestic sewage treatment by the biochemical system is more significant compared with that of stability pond.
