农村生活污水处理技术与示范工程研究

Research on rural sewage treatment techniques and application in demonstration projects

随着水体污染的日趋严重,农村生活污水处理已经提到日程上来,为研究适合农村生活污水处理的方法,对农村生活污水的排放特征和处理技术进行了探索,建立了“生物+生态”处理结合的组合技术,并进行了示范工程研究。结果表明三种组合技术均取得良好的处理效果,具有除磷脱氮效率较高,投资和运行费用低,维护管理方便的特点。农村生活污水处理系统应根据排放特征和环境气候条件,研究开发污水处理技术和生态农业利用相结合的方法,提高处理效率并降低运行成本。

Along with deteriorating water pollution, rural sewage treatment has been referred to agenda. To investigate suitable method for rural sewage treatment, its discharge characteristics and treatment techniques were explored. Integration techniques by combining ＂biology＂ and ＂ecology＂ method were established by demonstration projects research. Results indicated that three integrated techniques attained high removal ratio especially to phosphorus and nitrogen with low investment and running expense conveniently. According to rural sewage discharge characteristic and local climate, combination of sewage treatment techniques and ecological agriculture utilization should be developed to advance removal efficiency and decrease running cost.
