摘　　要：针对硫化钠废液剧毒、恶臭等问题,对现行业内主要的处理手段进行介绍及比较,其中包括了曝气法、汽提法、化学沉淀法、氧化法、湿式氧化法、碱液吸收法、生物法及综合利用法等,同时阐述了它们的优缺点和适用范围。最后得到结论:物化处理法及生物法仅适合低浓度的含硫化钠废液处理,不适用高浓度硫化钠废液处理,高浓度硫化钠废液应着力于对其进行资源化综合利用生产产品外售,以便达到处理收益均衡目标。In view of the high toxicity and odor of sodium sulfide waste liquid, the main treatment methods in the current industry are introduced and compared,including aeration method, stripping method, chemical precipitation method, oxidation method, wet oxidation method, lye absorption method, biological method and comprehensive utilization method, etc., and expound their advantages, disadvantages and scope of application. Finally, the conclusion is drawn: the physicochemical treatment method and biological method are only suitable for the treatment of low-concentration sodium sulfide-containing waste liquid, and not suitable for the treatment of high-concentration sodium sulfide waste liquid. Outsourcing in order to achieve the goal of processing income balance.
