水体中氮污染物处理工艺的研究进展
|
摘要
氮污染物的含量超标,易造成水体富营养化。氮污染物处理工艺包括物理法、化学法和生物法。主要叙述了处理工艺原理和应用实例,总结了各个处理工艺运行参数对氮污染物脱除的影响,并分析了各个处理工艺的优缺点和存在的问题。认为其中新型脱氮工艺是目前的研究重点,厌氧氨氧化与其他生物脱氮工艺联用可以实现高效、经济和稳定的脱氮。
When the concentration of nitrogen pollutants exceeds the maximum allowable concentration of water, water eutrophication occurs. The removal processes of nitrogen pollutants in water include physical, chemical and biological methods. This paper explains the principles of these three methods, gives their application examples, and summarizes the influence of control conditions in the operation of each process on the removal rate of nitrogen pollutants in water. Then it analyses the advantages and disadvantages of each treatment process as well as the unsolved problems. The authors believe that the new denitrification process is the focus of current research, and that the combination of anammox and other biological denitrification processes can achieve efficient, economic and stable removal of nitrogen pollutants from water.
