摘要:
目前我国很多农村地区的生活污水还得不到集中处理，其中的有机物、氮、磷等对周边水体造成一定污染。在南水北调中线工程中，为了确保进京水质的安全优良，库区汇水流域的农村面源污染问题必须引起重视。本文对适合处理农村生活污水的技术与方法进行了综述，包括人工湿地污水处理系统、稳定塘处理系统、生物膜处理技术等，并在此基础上介绍了复合人工快渗系统以及其的应用，并对南水北调水源区农村面源污染防治的实践进行了归纳。
Presently, the domestic sewage in rural
area could not be collected and disposed properly. Organic matters, nitrogen, phosphorus
in the sewage would pollute the surrounding water. In the South-to- North water
diversion project, to ensure high quality water for Beijing, we must pay
attention to rural non-point source pollution of the reservoir converge basin. In
this paper, the suitable techniques and methods of rural domestic sewage were
summarized, including Constructed Wetland Sewage Treatment System,
Stabilization Pond System, Membrane Biology Technology, etc. And on this basis,
this paper introduces the Compound Constructed Rapid Infiltration System and
its applications. The paper also summarizes practice cases of rural non-point
source pollution prevention and control in water source area of the
South-to-North water diversion project.
