无性系柳床人工湿地技术在农村生活污水处理中的应用

Application of Clones-shrub Willow Wetland Technology in the Rural Sewage Treatment

本项目将无性系灌木柳引入人工湿地，构建出一种用于农村生活污水处理的无性系柳床人工湿地技术，并在天津市静海县良王庄乡十里堡村建立示范工程。示范结果表明，该技术对CODCr、氨氮、总氮、总磷的去除率分别可达到88.0%～92.2%、90.4%～91.9%、90.5%～92.2%、92.8%～98.6%，截污减排效果显著。同时，无性系柳替代传统湿地技术的多年生草本植物，进一步降低了湿地系统的管理强度和运行成本，增加了湿地植物的经济效益，为农村生活污水处理提供了经济适用的技术。

This study proposed a new wetland technology by combining the clones-shrub willow and wetland technology to treat rural sewage,and then apply it in the demonstration projects in shilipu village,Liang Wang Township,Jinghai county of Tianjin. The results show that the interception effect of pollutant is significant with removal rate of COD,ammonia nitrogen,total nitrogen and total phosphorus varying 88.0%-92.2%,90.4%-91.9%,90.5%-92.2%,and 92.8%-98.6% respectively. In addition,this technology proves to be affordable for rural sewage treatment by utilizing clones-shrub willow instead of the traditional perennial herb,it can not only reduce the operating costs and the demanding of wetland management,but also increase its economic profit.
