氯碱盐泥资源化利用分析

Analysis on recycling of chlor-alkali salt sludge

盐泥是氯碱行业排放的固体废弃物,不合理处置将对环境造成很大污染。针对现有技术,分析5种盐泥处理方案:制备钻进液,制备吸附剂,制备有机肥料,进行污水处理,制备建材。同时提出技术融合,实现盐泥与其他废弃物的综合利用方案。

Salt sludge is a kind of solid waste discharged from chlor-alkali industry, and unreasonable disposal will cause great pollution to the environment. According to the existing technology, five treatment schemes of the salt sludge are analyzed: preparation of drilling fluid, preparation of adsorbent, preparation of organic fertilizer, sewage treatment, and preparation of building materials. Technology integration is also proposed to realize the comprehensive utilization of salt sludge and other wastes.
