摘　　要：The conventional wet FGD process has been applied in more than 85% units for SO2 removal in China. There are a great number of pollution components in the wastewater from wet FGD process,and the removal process of these components is very complicated and difficult,especially the removal of heavy metals in the wastewater. Even if a foreign advanced technology was applied,it is still difficult to meet the discharge requirements of heavy metals in spite of its much higher investment,operation and maintenance cost than that from the domestic widely-used and simple wastewater treatment process. Under the background of increasingly stringent environmental requirements,to improve the existing wastewater treatment process or to change the existing wet FGD process has become extremely urgent.The conventional wet FGD process has been applied in more than 85% units for SO2 removal in China.
