煤化工废水中含氮杂环化合物处理研究进展

Review on the Treatment of Nitrogen Heterocyclic Compounds in Coal Chemical Industry Wastewater

含氮杂环化合物是煤化工废水中常见的有机污染物,是造成此类废水难于处理的主要原因之一。本文介绍了国内外对含氮杂环化合物处理的的生物方法和物理化学方法,总结了不同方法对含氮杂环化合物的降解途径、降解原理及降解效果,最后对煤化工废水中含氮杂环化合物的处理提出了进一步的研究方向。

Nitrogen heterocyclic compounds treatmentare are common organic pollutants in coal chemical industry wastewater,they are also the main reason that why this kind of wastewater is difficult to be treatment.The biological treatment methods and the physical and chemical processing method for nitrogen heterocyclic compounds at home and abroad were introduced in this paper,summarizes the degradation pathway,degradation principle and degradation effect of the nitrogen heterocyclic compounds by different methods,and finally the further research direction of nitrogen heterocyclic compounds in coal chemical industry wastewater treatment were proposed.
