农村分散点源高效净化技术研究与工程示范

Research and project demonstration of high efficiency purification technology for rural distributed point source pollution

根据北京农村生活污水特点及治理需求,分析了几种分散型农村生活污水治理技术的特点,并将生化工艺与人工湿地有机结合,既节省运行成本,又能达到稳定的除磷脱氮效果。采用"生化+湿地"组合工艺在怀柔建设农村污水处理示范工程,其出水可以满足北京市2014年1月1日起实施的DB 11/307—2013《水污染物综合排放标准》中的B类标准,为北京农村分散式点源污染提供了一种绿色节能可行的技术解决方案。

According to the characteristics of Beijing rural sewage and demands of treatment, several decentralized rural sewage treatment technologies have been analyzed, which arrive at the conclusion that the combination of biological technology and artificial wetland technology to treat rural sewage have the better effect in removal of phosphorus and nitrogen with economic cost. Demonstration project combines biochemical process with wetland process to treat rural sewage in Huairou district, of which the effect of its effluent can meet the B standard of the comprehensive discharge standard of water pollutants in Beijing implemented since January 1, 2014 （DB11/307-2013）.The project above provides a feasible and green energy solution for treating rural distributed point source pollution in Beijing.
