人工湿地系统具有投资少、运行费用低、管理简单、处理效果稳定、便于就地回用等特点.在人工湿地的基础上增加曝气装置,推动了系统对COD的去除作用以及氨氮的硝化作用.研究表明,在进水COD为324mg/L、NH4+-N为34mg/L的条件下,出水平均浓度分别为25,3.8mg/L,达到了国家一级A标准.
Abstract：The construction of wetland system has many characteristics,which include less investment,low cost,simple management,stable treatment effect and easy to reuse etc.The aerating apparatus which boost the COD removal and nitrification is added on the base of the constructed wetland.The results show that,when the influent concentrations of COD,NH+4-N are 324,34 mg/L respectively,their average effluent concentrations are 25 and 3.8 mg/L,which measure up to the requirements of country grade I-A criteria.
