近年来,随着我国产业结构调整及技术创新,我国各行各业对铜的需求量大幅增长,尤其是电力、通信、邮电、交通运输、家电等行业的快速发展以及大量跨国公司的制造业涌入我国,使得国内铜及铜加工材料的需求骤增。以上各个行业的部分生产工序和废水处理设施每年都会产生大量的废渣或者废水处理污泥(统称铜泥),这些铜泥中仍然含有一定含量的铜等有价成分,采用相应的技术回收铜泥的铜,不仅保护了环境,而且可变废为宝创造出更多的社会价值和经济价值。近年来,我省上饶、赣州和抚州等市先后引进了10多家铜泥的加工利用企业,并且都取得了危险废物经营许可证。本文在对省内几家铜泥加工企业的处理技术、污染源强和污染防治情况分析的基础上提出加强铜泥加工企业监督和管理的对策。
In recent years, with the readjustment of industrial structure and technological innovation in our country, the demand for copper from all walks of life in our country has increased substantially. In particular, the rapid development of power, communications, telecommunications, telecommunications, home appliances and other industries as well as the manufacturing surge of a large number of transnational corporations Into our country, making the domestic demand for copper and copper processing materials surge. Some of the above production processes and wastewater treatment facilities in various industries produce a large amount of sludge or wastewater treatment sludge (collectively referred to as “copper sludge”) every year. These copper sludge still contain a certain amount of valuable components such as copper, and the corresponding technologies are used to recover copper sludge Of copper, not only protect the environment, but also turning waste into treasure to create more social and economic value. In recent years, Shangrao, Ganzhou and Fuzhou in our province have introduced more than 10 copper mud processing enterprises, and have obtained hazardous waste business license. Based on the analysis of processing technology, pollution source intensity and pollution prevention and control of several copper mud processing enterprises in the province, this paper puts forward some countermeasures to strengthen the supervision and management of copper mud processing enterprises.
