摘要:

煤化工废水是一种典型的有毒、难降解性工业废水。经预处理后的废水中仍含有大量的有毒有害物质,其中氨氮、酚类物质是典型的代表,氨氮含量在200mg/L左右,酚类物质含量占COD值的40%以上,浓度高达1000mg/L。如果对这些高毒性的物质不加处理或处理深度不够,则对环境和生命都会造成极大的危害。因此,酚类物质、氨氮的有效处理是实现煤化工废水无害化处理以及绿色可持续发展的关键。本综述主要从酚类物质处理技术与工艺、氨氮处理技术与工艺两个方面梳理了国内外煤化工废水中酚类物质、氨氮的处理现状,也全面分析了各种技术与工艺的优缺点。使该领域的研究人员以更加科学的方法了解煤化工废水中酚类物质、氨氮处理技术与工艺的研究现状和发展趋势。最后,探讨了未来煤化工废水中酚类物质、氨氮处理的发展前景。

Abstract:

Coal chemical wastewater is a typical toxic and refractory industrial wastewater. After pretreatment, this kind of wastewater still contains a large number of toxic and harmful substances, among which, ammonia nitrogen and phenols are the typical representatives. Ammonia nitrogen concentration is around 200mg/L, and phenolic concentration is up to 1000mg/L, accounting for more than 40% of the COD. Great harm would be put on the environment and life if these highly toxic substances were untreated. Therefore, the effective treatments for phenols and ammonia nitrogen are the key point to realization of the harmless treatment of coal chemical wastewater and green sustainable development. This review summarizes the current status for the treatment of phenolic substances and ammonia nitrogen in coal chemical wastewater, including phenolic substance treatment technologies and ammonia nitrogen treatment technologies. Furthermore, various technologies and processes in terms of their advantages and disadvantages are analyzed. This review is to allow researchers in this field to understand the research status and development trend of phenols and ammonia nitrogen treatment technologies and processes in coal chemical wastewater. Finally, the development prospects of phenols and ammonia nitrogen treatment in coal chemical wastewater are discussed.

Key words: coal chemical wastewater, removal of phenolic substance, removal of ammonia nitrogen, progress
