目前我国的农村生活污水处理还不够完善，处理设备配套不足和建设管理落后等问题，主要原因是：农村生活污水缺乏相应的污水排放标准；建设和运行资金落实不到位；重视不足。目前我国大部分农村缺乏完善的排水管道和污水处理系统，主要是直接排放或就近排入河道，目前我国农村生活污水处理存在的问题主要有：（1）农村多数铺设的污水管道，都是采用雨污合流的排水体制，没有进行合理的规划，畜禽粪便等随雨水进入排水沟，由于排水沟的断面较小，容易发生堵塞，严重污水周围的环境；（2）农村居民在房屋的建设和改造过程中，建设不符合标准，生活污水不经处理就直接排放到室外或河流，一部分只通过化粪池处理后直接排入地下，这对于地下水和土壤都造成了极大的污染，破坏人们的居住环境；（3）目前我国的农村已广泛应用水冲厕所，大量污水未经处理就直接排入灌渠，污水中的氮磷等污染物严重超标，污染农业灌溉水。 At present our country rural life sewage treatment is still not enough perfect, lack of form a complete set of processing equipment management and construction, the main reason is: lack of the corresponding rural sewage discharge standards; Inadequate implementation of construction and operational funds; Less attention. At present our country most of the rural lack perfect drainage and sewage treatment system, mainly is the direct emissions or nearby river channels, the problems existing in rural sewage treatment in China mainly include: (1) of laid of majority of rural sewage pipeline, is using the rain confluence drainage system, there is no reasonable planning, livestock and poultry dung, etc with the rainwater into the gutter, due to the drain of a smaller section are prone to congestion, severe water environment; (2) the rural residents in the process of construction and renovation of the building, building does not conform to the standards, living sewage without treatment is emissions directly to the outdoors or rivers, part only after the treatment of septic tank directly into the ground, for the groundwater and soil caused great pollution, destruction of people's living environment; (3) at present our country's rural areas has been widely used water to flush the toilet, a large number of untreated sewage directly discharged into irrigation canals, such as nitrogen and phosphorus in wastewater pollutants exceeds bid badly, the pollution of agricultural irrigation water.
