我厂炼铜车间原是一个采取氧化铜矿直接硫酸浸出,然后电解硫酸铜溶液,生产电解铜的湿法炼铜旧工艺流程。过去,每年向车间附近的河沟排放上万立方的含铜1—2克/升、含硫酸2—4克/升的废水和废渣,废水中废弃的铜每年达40吨之多,严重污染环境危害工人健康。去年,我厂在“工业学大庆”的群众运动中,发动群众,收旧利废,积极开展综合利用。 I plant was originally a copper plant copper oxide directly sulfuric acid leaching, and electrolysis of copper sulfate solution, the production of electrolytic copper copper wet process of the old copper. In the past, tens of thousands of cubic meters of waste water and waste slag containing tens of thousands of cubic meters of copper containing 1-2 g / l of copper and 2-4 g / l of sulfuric acid were discharged into the gully near the workshop every year. The amount of discarded copper in the waste water reached as much as 40 tons per year, seriously polluting the environment Endanger the health of workers. Last year, I plant in the “industrialization Daqing” mass movement, mobilize the masses, close old and new waste, and actively carry out comprehensive utilization.
