[PROBLEMS] To purify contaminants containing chlorinated organic compounds by a microbial decomposition reaction, increase the microbial decomposition reaction rate and ensure the reproducibility of the microbial reaction, and Provided are a purification method and a purification device which are more effective in decomposing the compound to an environmental standard value or less. SOLUTION: A contaminant containing a chlorine compound such as dioxins is put into a dechlorination stirring tank 1 whose temperature is arbitrarily adjusted, and chlorine is removed from the contaminant by a dechlorination microorganism having an optimum temperature of 60 ° C. Then, the contaminants from which chlorine has been removed by the dechlorinating microorganisms are put into a compound decomposition stirring tank 2 whose temperature is also arbitrarily adjusted. Decomposes the compound after removing chlorine contained in, and purifies pollutants. |
