摘　　要：制革遗留铬污染物以Cr^(3+)为主,存在转变为Cr^(6+)的可能。Cr^(6+)的存在会对堆放场土壤、地下水等形成严重威胁。本文分析了制革产业遗留堆放场铬污染的来源,总结了铬污染的特征及危害,对化学修复、PRB与电动联合修复、生物修复等制革遗留铬污染堆放场土壤与地下水修复技术研究进展进行总结,旨在对制革产业铬污染修复技术进行梳理,提升制革产业整体污染防控整治水平。Chromium pollutants left over from tanning are mainly Cr^(3+),which may be transformed into Cr^(6+).The existence of Cr^(6+) will pose a serious threat to the soil and groundwater of the dump.This paper analyzed the source of chromium pollution in the leftover dump of the leather industry,summarized the characteristics and harm of chromium pollution and the research progress of soil and groundwater remediation technology in the dump of chromium pollution left by leather industry,such as chemical remediation,PRB and electric remediation,biological remediation,etc.It aims to sort out the remediation technology of chromium pollution in the leather industry and improve the overall pollution prevention,control and remediation level of the leather industry.
