摘要
工业的快速发展导致废水的排放量增加,其中废水中的重金属离子会导致严重的环境毒性和具有潜在的致癌性。虽然目前已有很多技术研究已有效地应用在去除重金属领域上,但对这些技术方法的相关机理、优缺点、应用前景等信息缺乏总结综述。本文综述了近年来国内外去除废水中重金属离子方面所应用处理技术的研究进展,详细介绍了电解法技术、膜分离技术、置换沉淀技术和生物修复技术方法,并对这些方法的机理、优缺点和应用前景进行了综述和深入分析。
The rapid development of industry leads to an increase in the discharge of wastewater,which contains heavy metals that can cause serious environmental toxicity and potential carcinogenicity.Although many methods have been effectively applied to remove heavy metals from wastewater solutions,there is still a lack of enough information about their mechanisms,advantages and disadvantages,application prospects etc.In this paper,the research progress in the removal of heavy metals from wastewater in recent years is reviewed detailly,including electrolysis,membrane separation,displacement precipitation and bioremediation,etc.At the same time,the mechanism,advantages and disadvantages and application prospects of these methods are analyzed deeply.
