摘要
清洁水资源的日益短缺带动了废水处理科学和技术的进步。废水中顽固重金属的去除已被证明是一个具有挑战性的难题,需要开发出更多先进的水处理技术将重金属完全去除至无害化水平。本文对近年来废水中重金属处理技术的发展现状进行综述,包括光催化、浮选、化学沉淀、离子交换、电化学处理、混凝/絮凝、膜分离和吸附等技术,以期为未来高效可行的去除技术的选择和开发提供参考。
The increasing shortage of clean water resources has led to the advancement of wastewater treatment science and technology.The removal of recalcitrant heavy metals in wastewater has been proven to be a challenging problem,and more advanced water treatment technologies need to be developed to completely remove heavy metals to a harmless level.This paper reviews the current development status of heavy metals treatment technologies in wastewater in recent years,including photocatalysis,flotation,chemical precipitation,ion exchange,electrochemical treatment,coagulation/flocculation,membrane separation and adsorption,in order to provide a reference for the selection and development of efficient and feasible removal technologies in the future.
