摘要
介绍了生物蓄渗技术通过一系列的物理-生物-化学作用,可使出水的悬浮固体、营养盐、重金属、病原菌、油脂等污染物含量较低,并且能显著降低径流量与洪峰流量;生物蓄渗技术除了装置规模的设计外,还存在填料介质的筛选以及植物选择等问题。随着研究的深入,生物蓄渗技术控制径流污染的应用将越来越广泛。
Bioretention technology, which made the effluent pollutant contaminants such as suspended solids, nutrients, heavy metals, pathogens, grease and other pollutants low through a series of physical, biological and chemical processes, was introduced. The technology can significantly reduce runoff volume and flow peak. In addition to design of device scale, there also exist the prob- lems such as mediums selection and plants selection. With the advancement in research, the bioretention technology will become more widely used in runoff pollutant control.
