摘要:
针对农村污水产生分散及水量水质波动大的特点，设计出多反应区生物-生态组合处理工艺，并在北京市某村庄进行了工程应用。工程设计处理规模为3.0 m3/d，工艺主体为多级生物接触+反硝化滤池+生态滤池。其中，多级生物接触单元采用厌氧接触、兼氧接触及好氧接触工艺，反硝化滤池单元采用后置反硝化接触工艺。运行结果表明，该工程出水指标满足《城市污水再生利用 景观环境用水水质》（GB/T 18921—2019）中景观湿地环境用水水质要求。该工程的直接运行费用为0.99元/m3，具有较好的经济性。
Abstract:
Decentralized rural sewage is characterized by large fluctuation of water quantity and quality. This paper designed a biological-ecological combined process with multiple reaction zones and applied it in a village of Beijing. The design treatment scale of the project is 3.0 m3/d, and the main process consists of multistage biological contact oxidation, denitrification filter and ecological filter. Among them, the multi-stage biological contact oxidation consists of anaerobic contact, facultative contact and aerobic contact processes, and the denitrification filter adopts post-denitrification contact process. The effluent quality met the water quality requirements for landscape wetland environment in The Reuse of Urban Recycling Water—Water Quality Standard for Scenic Environment Use (GB/T 18921-2019). The direct operational cost of the project is 0.99 yuan/m3, showing a good economic benefit.
