文档介绍:浅析我国农村生活污水处理
存在的问题和改善措施
摘要:目前, 我国农村水环境质量普遍很差,已严重影响到农村居民的居住环境, 甚至造成了地下水污染, 继而影响到人民群众的身体健康。其次, 农业农村面源污染已占到水污染负荷的重要比例, 加强农村污水治理不仅关系到社会主义新农村建设, 也关系到整个经济发展。为了改善我国的水环境、保护水资源, 对资金有限, 技术力量薄弱的中小城镇和农村, 在学习国外成功和先进经验的基础上, 应采经济、简易、节能和有效的处理技术, 与当地的生态农业相结合, 在污水处理的同时实现污水的无害化和资源化, 实现水的良性循环和水资源的可持续利用。

Pick To: at present, China's rural water environmental quality in general is very poor, has seriously affected the rural residents' living environment, even caused the pollution of groundwater, which in turn affect people's health. Second, agriculture and rural areas non-point source pollution is important proportion of the water pollution load, strengthen rural sewage treatment not only relates to the socialism new rural construction, but also to the development of the economy as a whole. In order to improve our country's water environment, protection of water resources, the limited funds, technical force is weak of small and medium-sized town and country, and on the basis of learning essful foreign experience and advanced, and shall adopt economic and simple, energy saving and effective processing technology, combined with the local ecological agriculture, in the sewage treatment at the same time, non-hazardous disposal and reuse of sewage, realize the benign circulation of water and the sustainable utilization of water resources.
Key Words: pollution; Rural sewage; Processing technology
农村生产污水包括畜禽养殖业、水产养殖业、农产品加工等产生的高浓度有机废水以及农业生产过程中的耕地径流水。近年来, 由于禽畜养殖业从分散的农户养殖转向集约化、工厂化养殖, 禽畜粪便污染大幅度增加, 成为一个重要的污染源。如北京近郊禽畜养殖场排放的有机物污染, 相当于全市工农业生产污水和生活废水中所含的有机污染物的一倍。滇池流域的农业面源污染构成中, , %。农村污水量大面广, 污水中大量氮、磷等污染物质, 加重接纳水体污染, 造成水体水质恶化, 威胁农村饮水水质和水量, 影响村民居住环境, 严重威胁农民的身体健康。再者, 农村缺乏水循环利用的观念, 从而造成水资源浪费。因此, 在我国开展社会主义新农村建设和发展现代农业进程中, 为了避免因农村污水未经处理直接排放而对农村地区的水体、土地等自然环境产生污染影响和流域发生富营养化, 确保农村水源安全和农民身体健康,
