<p>PROBLEM TO BE SOLVED: To provide a treatment technique which efficiently and cost effectively treats org. chlorine compds. and eliminates the possibility of applying load of malodors, etc., to the ambient environment. SOLUTION: In the method of treating the pollutants consisting of the soil 1 and/or ground water 2 polluted by the org. chlorine compds.; an anaerobic layer of an anaerobic state is formed by adding the growth substrate of anaerobic microorganisms having reducing power to the pollutants. An aerobic packed layer 4 is formed by installing porous carriers to the soil part of the surface layer to dechlorinate the org. chlorine compds. The malodorous gases generated from the anaerobic layer 4, combustible gases or gases of the org. chlorine compds. are thus cracked and purified.</p> |
