生物慢滤技术在水处理中的应用现状及进展

Review on the Application of Biological Slow Filtration in the Treatment of Water Purification

水资源短缺及饮用水安全问题伴随着经济发展与人口增长日渐凸显,如何解决这一问题一直备受研究者关注。生物慢滤技术是一种效率高、能耗低、操作简易的绿色水处理技术。综述了生物慢滤技术的净化原理,全面阐述了该技术对浊度、有机污染物、细菌、金属类污染物的去除效果,针对当前生物慢滤技术研究中存在的一些难点问题,提出了今后研究的主要方向。

With the development of economy and population, water shortage and drinking water safety problems are becoming increasingly prominent. How tention of researchers. Biological slow filtration technology to solve those problems has attracted much at- is a ＂green＂ water treatment technology with high efficiency, low energy consumption and simple operation. The purification mechanisms of the biolog- ical slow filtration are introduced, and the research progresses on the removal of turbidity, organic pollu- tants, bacteria, metal pollutants by this technology are summarized. Aiming at some existing difficult problems in the current research of biological slow filtration technology, the main directions of the research in the field of biological slow filtration are put forward.
