磁分离/人工湿地工艺在河道水净化中的应用

Application and Development of Magnetic Separation-Constructed Wetland Combined Process for Field of Urban River Water Purification

采用磁分离/人工湿地组合工艺处理河道水,磁分离净水技术在去除水体当中的悬浮颗粒物和总磷时具有去除效率高、运行费用低、占地少的优点;人工湿地可以对溶解性污染物进行去除,是一种较好的生态废水处理方式,处理成本低、管理简单。将磁分离技术和人工湿地有机结合起来,可以取长补短,充分发挥两者的优势。在人工湿地的基础上发展磁分离/人工湿地工艺,可以处理受污染的城市河道水和城市公园湖泊景观水,也可以应用于农村水环境治理,具有广阔的应用前景。

By using the magnetic separation-constructed wetland combined process to removal the suspended particles and total phosphorous in the fiver water, this method has following advantages： high removal efficiency, low operating cost and less land occupation. Constructed wetland is a kind of ecological waste water treatment with low treatment cost and simple management. Combined constructed wetland and magnetic separation can take their advantages respectively. Magnetic separation-constructed wetland combined process developed from the constructed wetland can treat the polluted fiver water and urban landscape water, as well as the rural water environment. The magnetic separation-constructed wetland combined process has a wide application prospect.
