PURPOSE: To strengthen a decomposition treatment capacity for halogenated organic acids by inoculating soil polluted with the acids with a microorganism having dehalogenase which decomposes the acids hydrolysiswise. CONSTITUTION: In the decomposition process of halogenated organic acids which are a problem as byproducts in the sterilization and disinfection of water, especially the acids contained in soil, the soil is inoculated with a microorganism having dehalogenase which decomposes the acids hydrolysiswise. A microorganism of a renobacter group, preferably a renobacter species AC stock, is used as the microorganism. The halogenated organic acids include halogenoacetic acids and halognopropionic acids; the halogenoacetic acids include chloroacetic acid, dichloroacetic acid, and trichloroacetic acid; the halognopropionic acids include chloropropionic acid and dichloropropionic acid. The method is applicable to the soil restoration of both closed and open systems and can be implemented by a batch process, etc. |
