摘　　要：针对现有二硫化钼生产工艺回收率低、生产过程存在氮化物废气污染问题,开展了用氯酸盐氧化剂代替硝酸的研究,取得了较优工艺技术参数。在生产线上进行了应用试验,效果良好;从根本上消除了氮化物排放,提高了回收率,具有一定的经济效益和社会效益。According to the low recovery rate of molybdenum disulfide production and waste gas pollution problem in nitride, using chlorate oxidant instead of nitric acid in the production process was mainly studied, and good techni- cal parameters were achieved. The application tests were carried out in the production process, the result was good. The result showed the application of chlorate oxidant in the process eliminated the NOx emissions fundamentally, improved the recovery rate, and achieved certain economic efficiency and social benefits.
