曝气吹脱法去除水中三氯乙烯等有机污染物
Removal of Trichloroethylene and Tetrachloroethylene in Water by Aeration Stripping Process
摘要
Abstract
Under the circumstance of lab static test, the influence of different air-stripping removal rate of aeration volume on trichloroethylene and tetrachloroethylene was studied. The experiment result shows when the aeration volume is 0.4~1.4 L/min and when the gas/water ratio of trichloroethylene and tetrachloroethylene is 2.24~4.71(air)/L(water) and 1.10~2.43 (air)/L(water) individually, the concentration of both compounds could be removed to achieve National Standard from the initial which is 5 times as the standard. The result shows the aeration stripping can remove trichloroethylene and tetrachloroethylene within short time and thus aeration stripping can be adopted as an emergency treatment process to remove volatile contaminants.关键词
