摘　　要：六价铬离子由于其毒性大、不可生物降解和生物富集等特点,重金属铬污染已被确定为全球水生态系统的威胁。本文综述了现在广泛用于处理重金属铬废水的方法,包括离子交换法、溶剂萃取法、电解法、生物法以及吸附法等。目前,铬元素的治理仍需持续关注,以防止铬污染事件的发生,从而保护人们免受铬污染的危害。Hexavalent chromium pollution has been identified as a threat to the global aquatic ecosystem because of its toxicity, non-biodegradable and bioaccumulation characteristics. This paper provides a review of the methods that are widely used for treating heavy metal chromium wastewater, including ion exchange, solvent extraction, electrolysis, biological methods, and adsorption. Currently, it is crucial to continue to focus on the treatment of chromium to prevent the occurrence of chromium pollution incidents and to protect people from the harm caused by pollution.

关 键 词：铬污染 水处理 化学治理
