摘　　要：随着关于持久性有机污染物的斯德哥尔摩公约相关修正案在国内的生效,全氟辛基磺酸及其盐类(PFOS)在电镀行业的使用仅限于闭环系统的硬金属电镀,闭路循环系统可实现CrO_(3)、PFOS回用、废水循环使用且几乎无废物外排,因此探索实现闭路循环对于我国电镀行业尤其是硬铬电镀企业的绿色可持续发展具有重要意义。通过对比国内与国外在闭路循环镀铬系统的使用和研究方面的差异,提出了国内可行的闭路循环镀铬系统技术原则建议。With the entry into force of the relevant amendments to the Stockholm Convention on persistent organic pollutants in China,the use of PFOS(Perfluorooctanesulfonates)in the electroplating industry is only limited to the hard metal electroplating in a closed-loop system.Besides,the closed-loop system can realize CrO_(3),PFOS reusing,waste water recycling and almost no emissions into the environment.Therefore,it is of great significance to explore the realization of closed-loop system for the green and sustainable development of China’s electroplating industry,especially for hard chromium electroplating enterprises.By comparing the domestic and foreign differences in the use and research of closed cycle chromium plating system,some feasible technical principle suggestions for closed-loop chromium plating systems in China were proposed.
