<p>PROBLEM TO BE SOLVED: To rapidly perform the biological decomposition of org. waste such as garbage, a Shochu(a low class Japanese alcoholic drink) waste soln., livestock excretion or the like by biologically decomposing an org. matter having a specific particle size in a mixed soln. containing air bubbles having a specific particle size and microorganisms. SOLUTION: Raw water 4 containing a solid org. matter 2 is coarsely crushed by a disposer 8 to be sent to a raw water tank 10 and a suspension containing the coarsely crushed solid org. matter is supplied to a static mixer 20. Oxygen or air from an oxygen generator 20 is compressed by a compressor 26 to be sent to the static mixer 20 and the solid org. matter is ground into a particle size of 10-50μm herein along with oxygen or air. The mixed soln. having the solid org. matter ground by the static mixer 20, oxygen or air, microorganisms or the like suspended therein is subsequently sent into the bottom part of a reaction tower 30 through a cooler/heater 28 to be biologically decomposed. Since cells of the solid org. matter are destructed and an intracellular soln. flows out to the outside herein, biological decomposition can be rapidly advanced.</p> |
