农村生活污水处理技术的应用效果及其经济性分析研究——以重庆地区为例

Application Results and Economic Analysis of Sewage Treatment Technologies in Rural Environment Remediation in Chongqing City

为了解农村生活污水处理技术在应用过程中的效果。以重庆地区为例,对重庆市63个村庄的生活污水处理设施进行了调查。根据出水水质和建设成本,对村庄常用的污水处理技术进行经济技术综合比较分析。结果表明,无动力人工湿地较为经济,应用效果并不理想,在经济条件比较薄弱的地区可作为过渡型处理技术加以应用;渠道式生态沟投资较昂贵,不推荐使用;一体化设备投资昂贵,运行管理简单,在经济条件较好的地区可以考虑使用。

In order to understand the actual effect of rural sewage treatment technology in the application process, the sewage facilities in 63 villages were investigated in Chongqing. The economical and technical for common used sewage treatment technology through water quality and construction cost were compared and analyzed The results showed that unpowered wetlands are more economical, but practical application was not good. This sewage treatment technology can be applied as a transitional technology. The Eco -ditch is expensive, therefore not recommended. The integration device is expensive and the operation management is simple, therefore this sewage treatment technology can be applied in the areas which economic condition is wealthy.
