在人们的日常生活中,会产生一定量的生活污水,当不经处理随意排放时,会严重影响地下水质。农村中,生活污水处理的意识比较差,排水系统、污水处理设施并不健全,不仅严重了的水质污染,同时也浪费了水资源。农村生活污水中,含有比较多的营养元素,具有良好的可生化性,重复利用的价值比较高,基于此,本文阐述了农村生态型排水系统的构建方法,并分析了该排水系统的截污作用。 In people’s daily life, it will produce a certain amount of domestic sewage, which will seriously affect the quality of underground water when it is left untreated. In rural areas, the awareness of domestic sewage treatment is rather poor. The drainage system and sewage treatment facilities are not perfect, not only the serious water pollution but also the waste of water resources. In rural domestic sewage, it contains more nutrients, has good biodegradability and high value of reuse. Based on this, this paper describes the construction method of rural ecological drainage system, and analyzes the sewage interception of the drainage system effect.
