焦化废水氨氮去除方法的研究进展

焦化废水是煤制焦化产品回收过程中产生的废水,属于难处理的工业废水。文章就目前国内外针对焦化废水中氨氮的去除应用的各种物理化学方法,如蒸汽汽提法、吹脱解析法、离子交换法、折点氯化法、吸附沉淀法、电化学氧化法、催化氧化法等方法技术的原理及处理现状做出介绍,分析了各种处理方法的特点和出现的问题,并对处理焦化废水除氨氮做出展望。

Research Progress of Ammonia Nitrogen Removal Method of Coking Wastewater

The coking wastewater is produced in the process of the coking products of coal, it＇s belonging to the industrial waste water which is difficult to deal with. In the paper we introduced various physical and chemical methods for the ammonia nitrogen removal application at home and abroad aiming at the coking wastewater, such as steam stripping method, remove analytic method, ion exchange method, break point chlorination. Adsorption precipitation, the electrochemical oxidation, catalytic oxidation method and so on. The paper analyzed the characteristics of various methods and the problems in those processes.
