摘　　要：铬是环境中普遍存在的几种微量金属之一,铬作为环境中的一种主要重金属污染物,主要以三价和六价形态存在,其中的三价铬对人和动物是必需的微量元素,而六价铬则是一种毒性较大的致畸、致突变的有害物。当前含铬废水进入了综合防治、回收利用与总量控制阶段,基于含铬废水的回收是当前较为迫切的任务,本文重点阐述了重金属铬的绿色回收技术。Chromium was one of the several trace metals in our survival environment,mainly existed in trivalent（Cr3＋） and hexavalent（Cr6＋） forms,which was a major heavy metal pollutant.Among the trivalent（Cr3＋） and hexavalent（Cr6＋） chromium,trivalent chromium was an essential trace element for human and animal,while hexavalent chromium was a kind of hazardous substances,which had toxic,teratogenic and mutagenic.At present,comprehensive prevention,recycling and total control phase for wastewater containing chromium,based on the recovery of chromium-containing wastewater was an urgent task.Green recycling technology of heavy metal chromium was emphasized.
