Chlorinated hydrocarbons are common pollutants in groundwater.Taking groundwater contaminated with chlorinated hydrocarbons at a typical polluted site in the south as the research object,the combined technology of"aeration stripping+activated carbon adsorption"was validated through laboratory experiments to remove chlorinated hydrocarbons from groundwater,and on-site remediation pilot tests were conducted.The results show that using this technology combination can remove chlorinated hydrocarbons from groundwater,with a removal rate of over 98%,meeting the remediation target requirements.The initial concentration of pollutants has little impact on the removal of chlorinated hydrocarbons.Engineering practice has shown that this remediation combination technology is feasible in groundwater remediation.
