| 摘 要： | 目的]对廊道式人工湿地处理新农村生活污水的应用进行研究。方法]依托国家新农村建设项目对江西赣南地区的新农村调查,对农村生活污水的来源、特征和处理要求进行总结,并设计利用一种改进性人工湿地--廊道式人工湿地处理农村生活污水,并对其效果进行考察。结果]该工艺对农村生活污水具有良好的处理效果,试运行4个月后对COD、TP、TN的平均去除率分别为73.07%、73.25%、72.36%,连续6次采样分析其出水COD为20～35mg/L、TP为0.60～1.19mg/L、TN为6.88～11.21mg/L,出水指标优于《城镇污水处理厂污染物排放标准》一级B标准。结论]廊道式人工湿地造价低廉,可通过低洼地改造实现,是处理农村分散污染源,控制流域面污染的很好补充。

| Abstract: | Objection] The aim was to study application of channels constructed wetland in treatment of domestic sewages in new countryside.Method] Supported by construction of new rural areas project in China,we surveyed on new rural areas in Gannan,Jiangxi Province,summarized source,characteristics and treatment of domestic sewage in countryside,and designed channels constructed wetland for sewage treatment.Result] The technique is proven effective in sewage treatment.After the technique was conducted for a trial run for four months,removal rates of COD,TP and TN averaged 73.07%,73.25% and 72.36%,respectively.After continuous sampling for six times,effluent COD was analyzed 20-35 mg/L,TP was 0.60-1.19 mg/L and TN was 6.88-11.21 mg/L,better than that of Standard 1B ruled by Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant.Conclusion] Thanks for low investment,channels constructed wetland can be built by transformation of bottom land,proving a good way for treatment of diffuse pollution source and control of water non-point pollution. |
