某小城镇综合生活污水CASS工艺及人工湿地工艺的方案比选

小城镇综合污水处理是我国许多城镇发展面临的急待解决的问题,文章通过CASS工艺及人工湿地工艺方案比选,人工湿地是一种投资低、建设运营成本低、工艺简单的新型生态处理系统。该工艺成熟可靠,去除N、P能力强,出水各污染指标均能达到排放要求。在解决小城镇综合污水处理方面具有广阔的应用前景。证明了人工湿地工艺是一种适合小城镇污水处理的新型工艺,适合在小城镇推广应用。

Comparison and Choice of CASS and Constructed Wetland in Small Town Integrated Sewage Treatment

In our country, small town integrated sewage treatment is the urgent problems for the development of many cities. The paper put forward river water pollution controlling CASS technology and constructed wetland these two kinds of programs from the application. The technique was reliable, mature and with a good ability to remove N and P. Each pollution target of the leakage water could meet the emissions requirements. That proved the artificial wetland process fit small town integrated sewage treatment; it could be promoted and applied in small town.
