摘要
阐述了含锰废水的来源及危害,以Mn(Ⅱ)和Mn(Ⅶ)为研究对象,从化学、物理化学、生物处理及多技术耦合处理四个方面,详述了目前国内外对含Mn(Ⅱ)废水处理技术的研究现状;并概述了吸附法和螯合絮凝法对Mn(Ⅶ)的去除性能及发展趋势.对各种除锰技术的优缺点进行对比分析,并对含锰废水处理技术的发展前景作出展望.
Abstract
The source and harm of wastewater containing manganese are expounded.Taking Mn(Ⅱ)and Mn(Ⅶ)as the research objects,the research status of treatment technology for wastewater containing Mn(Ⅱ)at home and abroad is summarized from four aspects:chemistry,physical chemistry,biological treatment and multi-process coupling treatment.Futhermore,the removal performance and development trend of Mn(Ⅶ)by adsorption method and chelating flocculation method are analyzed.The advantages and disadvantages of various technologies for the manganese removal are compared and analyzed,and the development prospect of treatment technology for manganese containing wastewater in the future is pros-pected.
