摘要
针对煤化工废水治理的难题,通过分析现代煤化工废水中盐分来源和含盐废水水质,介绍了不同浓度含盐废水处理技术和蒸发结晶技术,对目前结晶杂盐资源化利用的技术路线进行总结。从4个角度提出了对高盐废水处置的管理建议。建议从源头进行污染物削减;建议对煤化工废水进行"大水管理",提高企业运行人员管理水平;鼓励加快高盐废水处理技术研发和推广;建议国家层面尽快完善含盐废水相关标准体系,加快煤化工分质结晶盐作为产品使用的标准研究及环境风险研究。
In order to treat coal chemical waste water efficiently, different waste water treatment technologies and evaporation crystallization technologies were introduced by analyzing the salt source and waste water quality. The salt resourcfulization from the coal chemical salty waste water was summarized. Some management suggestions were proposed from four aspects. Source control should be carried out to reduce pollution. It was necessary to improve the operating personnel management level and accelerated the research on high salinity waste water treatment technologies. It was urgent to improve the salty waste water standard system and accelerated the research about coal chemical crystalline salt product standard and relevant environment risk.
