| 摘 要： | 目前，小城镇污水处理是中国急需解决的环境问题。通过介绍人工湿地的概念、类型、机理．并结合永川市某污水处理厂的运行效果得出人工湿地处理技术在处理小城镇生活污水中具有投资低、操作简单和运行费用低等优点，具有广阔的应用前景。该组合工艺对CODCr、BOO5、SS、NH3-N、TP处理效果进行了研究，对CODCr、BOD5、SS的去除率均在90％左右，对NH3-N、TP的去除率分别可达到83％和72％，表明人工湿地对N、P的去除效果较其他处理工艺要为显著。该人工湿地出水均达到《城镇污水处理厂污染物排放标准》（GB18918—2002）第二类污染物最高允许排放浓度一级A类标准。

| Abstract: | The sewage treatment in small towns becomes an environmental problem exactly solved at present. This paper introduced the concept, classification, principle of constructed wetland. Connected with the sewage treatment in Yongchuan City,it comes out that the constructed wetlands have the advantages of low investment,simple performance , cheap operation cost and so on. The technology of constructed wetlands have widely application prospect. Removal rates of CODCr,BOD5,SS, NH3 - N and TP by this treatment were studied. Removal rates of CODCr,BOD5 ,SS were about 90%. Removal rates of NH3 - N,TP were 83% and /2%, respectively. Removal rates of N and P is better than other treatments. Discharge water quality is better than the discharge standard for urban sewage farm. |
