生态浮床与潜流湿地耦合处理生活污水示范效果分析

生态浮床与潜流湿地具有良好的净水效果,能吸收水体中有机污染物。较为系统分析了生态浮床与潜流湿地在上海某农村生活污水处理示范工程中的应用方法及其优缺点,实际考察了生态浮床与潜流湿地藕合技术在处理农村生活污水示范工程中的应用情况。运行结果表明,该工艺技术具有投资少、处理效果好、操作简单、维护成本低等优点,其出水水质达到《污水综合排放标准》(GB8978-1996)一级B排放标准。

Effect analysis of sewage treatment by the ecological floating bed and subsurface constructed wetland coupling technique

The ecological floating bed and subsurface constructed wetland can absorb organic pollutants in water and have an obvious sewage treatment effect.The application of the ecological floating bed and subsurface constructed wetland to one of rural-sewage treatment demonstration projects in Shanghai was systematically analyzed in this paper.The advantages and disadvantages of the treatment techniques were also discussed.An on-the-spot investigation into the application of the ecological floating bed and subsurface constructed wetland coupling technique to the demonstration project was carried out.The results of field operation showed that this coupling technique has the advantages of good treatment result,convenient operation,and low initial and maintenance costs.The water quality indicators are up to emissions standards level 1 B set in ＂Integrated wastewater discharge standard（GB8978-1996）＂.
