<p>PROBLEM TO BE SOLVED: To solve a problem that in which in addition to a gas dissolution tank in which gas is dissolved in a slurry sludge under the pressurization condition, and a breaking tank in which a slurry sludge in which gas is dissolved is broken under the pressure that is lower than pressure under the pressurization condition, two or more lines such as a sludge returning line and an excess sludge discharge line are required, and complication of an apparatus cannot be escaped.SOLUTION: A sludge treatment apparatus includes: a sludge supply tank 11 in which water including a sludge of a processing object is reserved; a water hammer part 14 in which a water W including a sludge is made to inflow from the sludge supply tank 11 through a conduit 13, and water hammer is generated; and a water level control part 12 in which a water level of the water W including a sludge in the sludge supply tank 11 is adjusted corresponding to a content of a sludge, wherein the conduit 13 is formed in a length in which a prescribed generation number of water hammer is generated corresponding to a water hammer generation period, and a sludge is broken by water hammer generated in the water hammer part 14. A treatment sludge after passing aeration treatment and sedimentation treatment is performed by water hammer treatment by the sludge treatment apparatus 10 and performed by volume reduction treatment.</p> |
