A method of treating sludge of a wastewater treatment process is provided to simplify deodorizaton facilities, reduce power ration and material costs, maintain uniform fermentation, and cut down second waste treatment cost. A method of treating sludge of a wastewater treatment process comprises the following steps of: fermenting a sludge fermentation material of a second fermentor by supplying air of 0.1~0.2m^3-air/m^2.min containing the sludge fermentation material in a first fermentor after injecting a compound of a sludge raw material and the sludge fermentation material and operating a first inhalation-air supply part(1); manufacturing a compound by adding the sludge raw material on remaining sludge fermentation material after removing a part of the sludge fermentation material; operating a second inhalation-air supply part(2); supplying the air of 0.1~0.2m^3-air/m^2.min containing the sludge fermentation material; and fermenting the sludge fermentation material in the first fementor. |
