<p><P>PROBLEM TO BE SOLVED: To provide a revolutionary sludge disposal method utilizing the biochemical autolysis action of a microorganism group being sludge. <P>SOLUTION: Sludge in a predetermined amount (e.g. 1/15 of a vessel) is incorporated into a water tank every predetermined time every day, further, air is continuously fed into the water tank charged with the sludge, and the inside of the water tank is made into an aerobic environment having a dissolved oxygen value in a high concentration. Then, the sludge is decomposed into carbon dioxide and water by the autolysis action of the microorganism group constituting the sludge, the amount of a supernatant liquid equivalent to the amount of the sludge charged every day is discharged, and the sludge is disposed of based on the autolysis action of the microorganisms. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
