METHOD FOR TREATING WATER CONTAMINATED BY TRICHLOROETHYLENE AND TETRACHLOROETHYLENE

摘要

PURPOSE:To decompose trichloroethylene or tetrachloroethylene contained in water to low molecular compounds so as not to remain in the environment by injecting a specified amount of ozone into water containing trichloroethylene, etc. CONSTITUTION:A gas dispersion pipe 4 equipped with fine glass filters is fitted to the tip of an ozone injection pipe 1 connected to an ozone generator 3, and this ozone injection pipe 4 is inserted into a treatment tank 2. 0.01 to 1.2mol ozone is injected for 1mol trichloroethylene or tetrachloroethylene contained in water. It is possible to decompose trichloroethylene or tetrachloroethylene in a very short time by the injected ozone and to prevent them from remaining in the environment.
