鄱阳湖区农村生活污水分散式处理探讨

Study on Rural Sewage Treatment through Decentralized Technology in Poyang Lake Area

本文通过对鄱阳湖区农村生活污水排放特征分析,探讨鄱阳湖区农村生活污水有效处理方式,结果表明近期鄱阳湖区农村生活污水处理适合采用3种处理模式:庭院式处理模式、小型分散式处理模式和分散式处理模式。并对这3种模式的核心单元进行了介绍和技术经济分析,指出鄱阳湖区农村生活污水具体处理工艺的选择要因地制宜,结合当地污水排放标准、经济水平和技术力量,组合选取合适的工艺。

In order to effectively treat rural sewage in Lake Poyang area, an analysis on rural sewage discharge characteristic was performed, the result indicated that the decentralized technology would be suitable for the rural sewage treatment in recent years. Thus, three types of decentralized technologies were put forward to treat the rural sewage in Lake Poyang area, which were domestic treatment model, miniaturized decentralized treatment model and decentralized treatment model. Furthermore, a technical and economical analysis was performed on the core of treatment units of the three decen- tralized technologies. In sum, the suitable treatment technologies to rural sewage in Lake Poyang area should be combined geography conditions, sewage discharge criterions, economical level and technical strength of the area.
