| Abstract: | Volatile chlorinated organic compounds are the kind of organic contaminant that has the higher detection frequency in groundwater, and that is the main byproducts of drinking water disinfected with chlorine. The volatile chlorinated organic compounds have been proved to be harmful to human’s health by USEPA. This paper described the treatment technology of volatile chlorinated organic compounds in groundwater by permeable reactive barrier (PRB) including the materials of PRB, degradation mechanism, the factors of dechlorination efficient, and the problems of engineering and development direction. It introduces the newest development and practical value of reductive dechlorination by PRB. It proposes the potential and problems to be solved. Particularly, there are problems of catalytic principle and catalyst deactivation in bimetallic systems. The paper will give some study information for domestic researcher. |
