摘　　要：某西北铅锌冶炼厂实施了“老硫酸系统尾气深度治理项目”,针对本铅锌冶炼厂氧化锌能就近取用,不需要外购原料,为制酸系统配套建设氧化锌脱硫技术系统,同时,脱硫后的溶液可以返回到湿法生产中去,不会给环境造成新的污染。改造后SO_(2)、硫酸雾、颗粒物稳定达标运行,减排做到了正向促进,脱硫后溶液可资源化,实现了循环经济生产,对铅锌厂的可持续发展具有重要的意义。A northwest lead and zinc smelter implemented the"old sulfuric acid system exhaust depth treatment project",for the factory zinc oxide can be used nearby,do not need to purchase raw materials,for the acid system supporting the construction of zinc oxide desulfurization technology system,at the same time,the desulfurization solution can be returned to the wet production,will not cause new pollution to the environment.After the transformation,SO_(2),sulfuric acid fog and particulate matter run stably up to the standard,the emission reduction has been promoted positively,the solution can be recycled after desulfurization,and the circular economy production has been realized,which is of great significance for the sustainable development of the lead and zinc plant.
