地表水处理中的河岸渗滤作用

Riverbank Filtration for Surface Water Treatment

河岸渗滤作为一种简单廉价的自然过滤系统,在欧美各国的供水系统中得到了广泛的应用。文章介绍了河岸渗滤系统在国际上的研究与应用情况以及该工艺的优点;分析了河岸渗滤系统对污染物的消减机制;对氮化合物、水生病原体、蓝藻和蓝藻毒素、人工合成有机物等污染物的良好去除效果;最后展望了其在我国现阶段水质条件下的应用前景。

As a natural filtration system, riverbank filtration is simple, inexpensive, and widely applied in Europe and North America. Research progress and application of riverbank filtration in different countries, as well as its advantages, was introduced. The mechanism to reduce or eliminate the contaminants, and the removal efficiency of nitrogen, waterborne pathogens, eyanobacteria and microcystins, artificial organic pollutants, etc. in this process were also illustrated. Finally, the perspective of the application of riverbank filtration was summarized.
