  • 摘要: 炼焦过程中会产生大量的废气、废水和危险废物,炼焦行业是重污染行业,也是我国重点管控行业。炼焦行业危险废物的精准管控和安全利用处置,既可改善生态环境,也可保障人类健康。炼焦行业危险废物的产生现状是产生节点多样、产生量大、污染物种类繁杂,采取的主要利用处置方式包括从高温煤焦油和中低温煤焦油中提取多种化工原料、以脱硫废液为原料进行提盐和制酸、现阶段无法有效利用的炼焦危险废物水泥窑协同处置和焚烧处置。对当前利用处置方式存在的主要问题进行了剖析,提出了3个提高炼焦危险废物利用率和加强安全处置的建议:1)遵循《危险废物豁免管理清单》利用环节豁免条件,促进高温煤焦油和中低温煤焦油利用;2)通过制定污染控制标准或技术规范、“点对点”利用、开发高效的提盐和制酸技术、园区统一规划集中利用等方式,合力提高脱硫废液提盐和制酸的利用水平;3)在环境风险可控和利用新型干法回转窑工艺以及危险废物科学配伍的前提下,将现阶段无法有效利用的炼焦危险废物进行水泥窑协同处置和焚烧处置。
