| 简介 |
PROBLEM TO BE SOLVED : To provide a method of making the diffusion prevention of contaminated soil by a permeable pipe and cleaning possible for the principle of the natural circulation and cleaning harmful substances by injecting water to the deep underground by a high pressure pipe, while the stabilization principle of the substances of the natural circulation observed in a hot spring for which rain water on a mountain peak is made harmless deep underground through the long period of the unit of several thousands years is optimum as a means to be applied to the detoxification treatment of active harmful substances created by human beings for global environment maintenance, and a method of efficiently extracting contamination from the contaminated soil and injecting water to the deep underground while the natural circulation can detoxify organic substances when the cycle of a long period is considered. SOLUTION : In the cleaning method of the contaminated soil, since water is a medium, a stream of ground water is artificially formed, and harmful substance is extracted by the infiltration of water in a permeable pipe. Flocculation and concentration are executed using a chemical agent for the purpose of improving efficiency as needed, the water is injected into deep underground using a high pressure water injection pipe to clean earth contamination, and the detoxification is executed utilizing the natural circulation principle of the deep underground.
