摘　　要：表面处理行业通常会使用大量强酸(盐酸、硫酸、硝酸等),每年废酸产生量接近1亿t。废酸液具有酸度高、毒性强、产量大、难处理等特点,对环境和人体健康存在巨大威胁,同时资源得不到有效回收利用。针对酸洗废液水质特点,本文总结了当前的处理技术,并对未来处理模式提出展望。The surface treatment industry usually uses a lot of strong acids(hydrochloric acid,sulfuric acid,nitric acid,etc.),and the annual waste acid production is close to 100 million tons.Waste acid liquid has the characteristics of high acidity,strong toxicity,large output,and difficult to handle,which poses a huge threat to the environment and human health,at the same time,resources cannot be effectively recycled.In view of the characteristics of the water quality of the pickling waste liquid,this paper summarizes the current treatment technology and puts forward a prospect for the future treatment mode.
