PROBLEM TO BE SOLVED: To provide a simple and low-cost treatment method of such removal sludge since various kinds of methods, for example such as an anaerobic digestion method and an aerobic activated sludge method, are known as a method for purifying sludge but in these methods, the sludge insists on settling in a sedimentation tank and excess sludge is necessary to be removed for each fixed period to bring it outside the system. SOLUTION: The method comprises the crushing of the dried material of the removal sludge generated from various sludge purification methods, its introduction into a treatment tank filled with a nanometer air bubble and its bio decomposition in the tank, and the method comprises the introduction of the removal sludge from the sedimentation tank of the various sludge purification methods into the treatment tank filled with the nanometer air bubble and its bio decomposition in the tank.
