METHOD AND APPARATUS FOR CLEANING POLLUTANT

摘要

PROBLEM TO BE SOLVED: To provide a method and apparatus for cleaning a pollutant effectively by a rapid microbial decomposition reaction while ensuring the reproducibility of microbial reaction in cleaning the pollutant containing an organochlorine compound and decomposing the organochlorine compound so as to clear an environmental standard value. SOLUTION: The pollutant containing a chlorine compound such as dioxins is charged in a dechlorinating stirring tank 1 of which the temperature is adjusted arbitrarily and chlorine is removed from the pollutant by dechlorinating microorganisms with the optimum temperature 60 deg.C and the pollutant from which chlorine is removed by dechrorinating microorganisms is charged in a compound decomposition stirring tank 2 of which the temperature is adjusted arbitrarily in the same way and the compound after the removal of chlorine contained in the pollutant is decomposed by compound decomposing microorganisms with the optimum temperature of 65 deg.C to clean the pollutant.
