【摘要】 Cr(Ⅵ)通常以含酸根形式存在,是具有强毒性的物质,也是8种对人体危害最大的化学物质之一,容易侵入人体,导致人体出现癌变、畸形、基因突变等,而且会持久地污染环境。本文综述了国内外目前含Cr(Ⅵ)电镀废水处理技术的研究及应用现状,重点综述了吸附法、微生物法、还原法、电解法和萃取法等处理技术的原理、方法和特点,并对含Cr(Ⅵ)电镀废水的治理技术的未来发展做出了展望。更多还原

【Abstract】 Cr( Ⅵ) usually existed in the form of acid radical, which was a highly toxic substance and one of the eight most harmful chemicals to human body. It was easy to invade the human body, lead to canceration, deformity, gene mutation, etc., and would permanently pollute the environment. In this paper, the research and application status of the treatment of electroplating wastewater contained Cr( Ⅵ) in China and abroad were reviewed. The principles, methods and characteristics of five treatment methods(adsorption method, microbial method, reduction method, electrolysis method and extraction method) were introduced. Finally, the future development of treatment technology of electroplating wastewater contained Cr( Ⅵ) was prospected.更多还原
