摘　　要：综述了本课题组近年来在焦化脱硫废液资源化技术方面的研究进展,介绍了以焦化脱硫废液中"硫氰酸盐的纯化提取和水回用"为核心而集成的几种主要技术,主要包括多功能选择性吸附材料、耐高温耐腐蚀的亚微米级多孔金属复合膜及高效分离除杂技术和脱硫废液中硫氰酸盐的纯化提取及水回用工艺技术。本技术的成功产业化,在彻底解决焦化脱硫废液严重污染环境问题的同时,实现了脱硫废液的高效资源化及产品的高值化,让企业在提高环保水平的前提下获得明显的经济效益,促进了焦化行业的清洁生产和健康发展,开辟了焦化和钢铁行业环境保护的新途径。The progresses of our group in the resourceful treatment of waste liquid from the desulfurization of coke oven gas in recent years were reviewed. Aimed at extracting inorganic salts from the waste liquid and reusing water, three technologies, namely a multifunctional selective- adsorption material, composite porous metal membrane with high temperature tolerance and corrosion resistance, and the extraction and purification of thiocyanate with water reuse, were introduced. The successful industrialization of these technologies would not only solve the serious pollution problems, but also achieve the efficient utilization of the desulfurization wastewater and high economic benefit.
