多氯联苯污染场地现场清运实践探讨

《关于持久性有机污染物(POPs)的斯德哥尔摩公约》明确规定于2028年前完成含PCBs液体和被PCBs污染设备的环境无害化管理,浙江省在2006年1月正式启动了PCBs废物削减和处置示范项目。列举了PCBs的危害和处置的紧迫性,在经历多处封存点修复清运工作后,总结了集中封存的PCBs电力电容器现场修复清运的准备工作和修复方法,系统再现了PCBs封存点土壤修复的作业流程及修复中的注意要点,并对今后土壤修复的清运工作提出了建议。

The Stockholm Convention on Persistent Organic Pollutants （POPs）defined the environmental-friendly management of PCBs-eontaining liquid and PCBs contaminated equipment has to be completed before 2028. Thanks to this convention, Zhejiang Province was officially launched the demonstrative project on PCBs waste reduction and disposal in January 2006. This paper overviewed the importance and urgency to conduct the disposal on PCBs hazard wastes;summarized the in-situ practice experiences based on the PCBs-contained-capacitor＇s cleanup works,which had already archived the remediation goals;and eventually try to systematically reproduce the in-situ remediation procedures on PCBs comaminated soil cleanup. Certain suggestions related to overcome the key-issue that may be encountered during the cleanup works were proposed.
