钛白废酸回收利用项目全线贯通
http://www.tydo.tw2019-03-12 00:00:00中国化工报

  益诺欧环保集团首个硫酸法钛白粉废酸资源回收项目在四川攀枝花大互通钛业有限公司全线贯通,并完成调试顺利达产。该项目将22%废酸净化后浓缩,获得达到工业一级品标准的65%浓度的硫酸产品,酸回收率高达95%。大互通循环利用项目是国内首个硫酸法钛白粉生产废酸及废水回收项目,采用益诺欧的钛白粉酸性废水处理资源全回收技术,?#28304;?#20114;通现有钛白生产线产生的22%稀硫酸为原料,将其提纯浓缩至65%,并把废水中钛白粉颗粒和金属提取回收,实现酸性废水、废酸的全资源回收。据介绍,该项目在蒸发浓缩过程中不产生结晶,可确保设备能够稳定运行。同时全部废酸处理过程不产生污泥,可实现水、酸、金属的全部闭链循环。
