Zusammenfassung:PROBLEM TO BE SOLVED: To provide a decomposition treatment method of organic sludge which enables the ideal decomposition treatment of the organic sludge containing a large amount of organic polluted substances as it is, and its treatment by simple facilities and at an inexpensive running cost, and to provide a decomposition treatment device of the organic sludge. SOLUTION: The decomposition treatment method of the organic sludge for carrying out decomposition treatment of the organic polluted substance in a substance to be treated at a purification area by serving the organic sludge containing the organic polluted substance as the substance to be treated comprises introducing the substance to be treated into the purification area filled with a large number of bulk aggregates having a surface with a diameter of 5 to 20 cm which aggregate to join a plurality of crushed stones with a diameter of 1 to 3 cm and an aperture and a pore space inside, and placed with a plurality of air diffuser pipes at an interval of 20 to 50 cm in a moving direction of the substance to be treated in the vicinity of the bottom part; moving the introduced substance to be treated by air diffuser from the plurality of air diffuser pipes; and controlling the substance to be treated in the purification area so that the volume residence time is 3 to 30 days.
