摘要
在工业生产、矿山开发、农业活动及城市生活等人类活动中通常会排放含有重金属离子的废水.这类废水具有毒性高和难降解性等特点,若未经处理而直接排放,会对周边生态环境造成严重污染,重金属离子易通过食物链传递,对人类健康造成不利影响.基于此,本文综述了处理含有重金属离子废水的技术、设备和工艺流程,以期为重金属废水的处理提供基础理论.
Abstract
Heavy metal ions containing cadmium(Cd),copper(Cu),copper(Cu),mercury(Hg),zinc(Zn),arsenic(As),nickel(Ni),chromium(Cr),cobalt(Co)and lead(Pb)are usually discharged in industrial production,mine discharge,agricultural activities and urban life.This kind of wastewater is characterized by toxicity,refractory degradation and metabolic difficulties.If not treated,directly discharged,it will cause pollution to soil and water,will be transmitted through the food chain,and will affect human health.This paper summarizes the technology,equipment and process for treating wastewater containing heavy metal ions.
