摘    要：铬及其化合物在当今诸多行业得到了广泛的应用，但是Cr(Ⅵ)与Cr(Ⅲ)往往存在于废水废渣中作为环境污染物文章主要是以铬为研究对象，综合论述和分析了现阶段各种针对含铬废水以及铬渣的回收方法及处理工艺现行绝大多数处理方法均是以对含铬废水废渣资源化利用为目的，一方面可以带来显著的经济效益，另一方面也保护了环境，具有良好的社会效益。

Abstract:

Nowadays chromium and its compounds are widely used in lots of industries. But the trivalent chromium (Cr³⁺) and hexavalent chromium (Cr⁶⁺) always exist in the waste water and the waste residues are regarded as environment pollution. In this paper, all kinds of current recycling technology and process for chromium as waste water and residues are discussed and analyzed comprehensively. Most of present technologies and processes are aimed to make them useful resources, which increase not only economic benefit but also social benefit via environment protection.
