摘　　要：膜分离工艺具有能耗低,适应性强,选择透过性好,分离过程中无相态变化,能在常温下进行等特点而广泛应用。根据分离的粒子半径的大小,膜分离可分为微滤,超滤,纳滤,反渗透。本文综述了微滤,超滤,纳滤,反渗透等膜分离工艺在重金属废水处理中的应用。Membrane separation technology with low energy consumption,strong adaptability,good choice through the sexual,no phase change during the process of separation,can be at room temperature.And the application prospect is wide.According to the size of the separation of particle radius,membrane separation can be divided into microfiltration,ultrafiltration,nanofiltration,reverse osmosis.This paper reviews the application of membrane separation technology in heavy metal wastewater.
