摘要
分析了电镀污泥处理的现状,针对电镀污泥中铬铜等多金属资源化高值利用,提出了一套完整的新工艺,通过优先提铬、介质循环等技术,利用电镀污泥生产出了碱式硫酸铬、电积铜等产品,实现了电镀污泥二次资源的循环利用,经济效益和社会效益显著。
This paper analyzed the present situation of electroplating sludge treatment, a new technology was put forward for high-value resourcization of chromium and copper metals in electroplating sludge.By using the patent technology,such as chromium preferential extraction and medium cycle, produced basic chromium sulfate and electrolytic coppers from electroplating sludge, realized the recycling of electroplating sludge secondary resourc- es, therefore, economic benefit and social benefit both were remarkable.
