中文摘要: 中国是全球重要的工业制造基地。随着工业化进程的加速,特别是在冶金、皮革、电镀等行业中,铬元素被大量使用,造成了严重的环境污染。铬在环境中大多以Cr(III)和Cr(VI)的形式存在,其中,高毒性和强氧化性的Cr(VI)对于生态系统和人类健康存在巨大危害。中国铬污染主要集中于工业重镇和工业遗址等场地,这些场地中大量含铬废水和废物在处理不达标甚至未经处理时就排放到环境中,造成广泛的铬污染。本文首先介绍了中国铬污染场地的现状和危害,然后阐述了铬污染场地未来仍以治理为主的思路,其中修复材料固定化法因其成本低廉、绿色环保、适宜大规模治理成为主流修复方法。目前,土壤和水体中的铬污染已经严重影响农业生产和生态平衡。面对铬污染的严峻挑战,加快开发高效、低成本的污染治理技术,实现铬资源的循环利用成为当前的研究热点。
Abstract:As a globally important industrial production base, the widespread use of chromium in China has led to serious environmen‐tal pollution problems as industrialisation has accelerated, especially in the rapid development of metallurgy, electroplating, leathermanufacturing and other industries. Chromium mainly exists in the form of trivalent chromium and hexavalent chromium, of whichhexavalent chromium poses a great threat to the environment and human health due to its high toxicity and strong oxidizing properties.Chromium pollution in China is mainly concentrated in sites such as industrial towns and historical industrial sites, where large quanti‐ties of chromium-containing wastewater and wastes are discharged into the environment without treatment or improper treatment, lead‐ing to extensive chromium pollution. This review firstly introduced the current situation and risk hazards of chromium-contaminatedsites in China, and then elaborated that the future development trend of chromium-contaminated sites was still dominated by treatment,in which bioremediation had become the mainstream remediation method due to its low cost and green environment. At present, chromi‐um pollution in soil and water had seriously affected agricultural production and ecosystem balance. In the face of the serious challengeof chromium pollution, how to accelerate the development of efficient, low-cost chromium pollution control technology, to achieve the re‐cycling of chromium resources had become a hot spot in today""s research.
