摘要
重金属是最常见的一类环境污染物质,广泛存在于自然界中。常见的废水中重金属离子去除方法包括:化学沉淀法、离子交换法、膜分离法、电化学处理法及吸附法等,分析了每个方法的优缺点,为不同情况下去除重金属离子提供可行性方法。
Heavy metals are one of the most common environmental pollutants,which widely exist in nature.The common methods of removing heavy metal ions from wastewater are introduced,including chemical pre⁃cipitation,ion exchange,membrane separation,electrochemical treatment and adsorption,etc.The advantages and disadvantages of each method are analyzed,and the feasible methods for removing heavy metal ions in dif⁃ferent situations are provided.
