农村生活污水处理与利用的简易模式初探

针对目前农村生活污水处理设施普遍存在建造成本高、运行维护难度大、难以在农村地区推广普及等问题,在此提出了一种农村生活污水处理的简易模式,该模式由化粪池沉淀、厌氧消化、简易过滤器净化及还田利用四部分组成,该简易模式示范工程的浅层地下水样COD值达到《城镇污水处理厂污染物排放标准》（GB18918-2002）二级标准.这个构建的农村生活污染处理简易模式实现了生活污水就地处理和资源化利用,可作为当前农村生活污水处理的过渡模式,在污水收集及处理系统还没有遍及的农村地区应用推广.

A Simple Model of Rural Domestic Sewage Treatment and Its Utilization

Aiming at the problems of current rural domestic sewage facility, such as high construction cost, difficulty operation maintenance, difficult to popularize in rural area, a simple treatment mode was put forward. This mode is composed of septic tank deposition and digestion, simple filter purifying, and agriculture irrigating. The shallow groundwater sample COD of mode can meet the second class criteria specified in Discharge Standard of pollutants for municipal wastewater treatment plant（GB 18918-2002）. The simple model can treat rural domestic sewer- age in situ and realize resource utilization of wastewater. Therefore, this model is appropriate for treating domestic sewage in the rural areas where have not sewage treatment system.
