| 摘 要： | 煤化工废水水量大，水质复杂，化学需氧量（COD）最高可达30000mg/L，是一种典型的处理难度高的工业废水。油类物质、酚类物质以及氨氮是煤化工废水中污染物质的主要组成成分，其最高浓度分别可达10000mg/L、9000mg/L、4000mg/L。如果不回收，则造成资源的严重浪费。因此，油类物质、酚类物质以及氨氮的有效回收是实现煤化工废水无害化处理不容忽视的问题。本文主要从油类物质、酚类物质、氨氮的回收技术与工艺3个方面梳理了国内外煤化工废水中油类物质、酚类物质以及氨氮的回收现状，并对各类技术的优缺点进行了对比和分析，其目的是让该领域的研究人员以更加科学的方法了解煤化工废水中油类物质、酚类物质以及氨氮的研究现状与发展趋势。最后基于节能、高效、持续健康的发展理念，探讨了未来煤化工废水中油类物质、酚类物质以及氨氮回收的前景。

| Abstract: | The amount of wastewater from coal chemical industry is large and the water quality is complex with the highest COD of 30000mg/L. This typical industrial wastewater is difficult to be treated. The main pollutant constituents in coal chemical wastewater are oily substances, phenolic substances, and ammonia nitrogen and their highest concentrations can reach 10000mg/L, 9000mg/L, and 4000mg/L, respectively. It will cause a serious waste of resources if they are not recycled. Therefore, the effective recovery of oil, phenols, and ammonia nitrogen is a significantly ignored issue for realizing the harmless treatment of coal chemical wastewater. This review summarizes the current status of the recovery technologies for oily substances, phenolic substances, and ammonia nitrogen in coal chemical wastewater from three aspects, including oily substance recovery technologies, phenolic substance recovery technologies, and ammonia nitrogen recovery technologies. Furthermore, various technologies in terms of their advantages and disadvantages are analyzed for the understanding on the research status and development trend of oily substances, phenolic substances, and ammonia nitrogen recovery technologies in coal chemical wastewater. Finally, based on the development concepts of energy saving, high efficiency, and sustainable health, the recovery prospects of oily substances, phenolic substances, and ammonia nitrogen are discussed. |
