摘要
人类的超强度活动导致水体中氮磷超标,是造成水体富营养化、发黑发臭、生态功能失衡的主要原因。目前去除氮磷的方法主要有生物法(短程硝化反硝化和好氧反硝化)、化学法(投加药剂法)和物理法(吹脱法和材料吸附法)。其中物理吸附法相比于其他方法,具有价格低廉、材料来源广泛、无二次污染、适用于大面积城市污水的特点。综述了近年来国内外吸氮除磷材料的研究和应用现状,着重阐述了矿物型和非矿物型吸氮除磷材料的应用效果,并对其应用前景进行展望。
The excessive nitrogen and phosphorus in water caused by human activities are the main causes of water eutrophication,blackening and the imbalance of ecological functions.Current methods to remove nitrogen and phosphorus mainly include biological methods(short range nitrification denitrification and aerobic denitrification),physical method(blow off treatment and material adsorption),chemical method(dosing reagent).Compared with other methods,the physical adsorption method has the characteristics of low price,wide material source,no secondary pollution,suitable for large area of urban sewage.the recent research and application of nitrogen and phosphorus removal materials at home and abroad were reviewed.The application effects of mineral and non mineral type nitrogen and phosphorus removal materials were emphatically expounded,and prospects for its application were expected.
