Method for removing hydrochloric ether contained in underground water and soil mud system through chemical reduction

The invention relates to a method for removing hydrochloric ether contained in underground water and a soil mud system through chemical reduction, and belongs to the technical field of environmental management. The method mainly removes certain hydrochloric ether contaminants which exist in the underground water and the soil mud system through the reduction action of ZVI (Zero-Valent Iron). The method achieves the purpose of hydrochloric ether treatment by adding the zero-valent iron to the mud system which contains the hydrochloric ether contaminants in a treatment process. The method disclosed by the invention is simple, effective and outstanding in treatment effect. According to the invention, the zero-valent iron is rich in source, low in cost and higher in reducing capacity, and the hydrochloric ether can be fast dechlorinated and degraded and achieves high removal efficiency, for instance, the removal ratio of 1,1,1-trichloroethane can achieve 99.5%. The method disclosed by the invention can be used for simultaneously treating the hydrochloric ether contained in the underground water and the soil mud system and is less influenced by temperature and pH on reaction process and wide in application range.
