废水处理与水资源循环利用是影响现代煤化工产业可持续发展的关键问题之一。基于我国对煤化工废水处理的标准与循环利用的要求不断提高,综述了我国对煤化工废水排放的政策变化过程,以及煤化工产业与水资源利用和废水处理的工艺发展;对近年来全球煤化工废水处理研究论文的数量,特别是我国在煤化工废水处理领域的研究成果进行了统计分析,指出我国在煤化工废水处理工艺的开发与应用领域处于领先地位,今后不仅要注重具体煤化工废水处理工艺的开发,同时也应加强工艺系统的优化和监控。

Wastewater treatment and water reclamation have been considered as one of key factors influencing sustainable development of coal chemical industry.Based on the ever-increasing requirement for the standard and recycling of coal chemical wastewater treatment in China, the authors review the policy change process of coal chemical wastewater discharge in China, as well as the development of coal chemical industry, water resources utilization and wastewater treatment technology. The number of research papers on coal chemical wastewater treatment in recent years, especially in China are analyzed statistically. Based on global survey on number and quality of research articles and the scale and faculties applied for wastewater treatment and water reclamation, China become the leader of coal chemical industry wastewater treatment techniques and related application field. In the future, attention should be paid not only to the development of specific coal chemical wastewater treatment technology, but also to the optimization and monitoring of the treatment system.
