9 Claims

1. An apparatus for ultrafinely shattering organic particle substances contained in slurry for being decomposed by bacteria, said apparatus comprising:

a cylindrical casing having a top wall, a bottom wall and two or more substantially concentric cylindrical walls arranged between the top wall and the bottom wall so as to define annular passages between the adjacent cylindrical walls;

a water injection device for injecting a pressurized water tangentially into the annular passage so as to generate high-speed water flows of 8 m/second or more in a circumferential direction therein; and

a supply port formed as a slot-like nozzle in the cylindrical wall so that the slurry can be supplied into the high-speed water flows through the nozzle perpendicularly to the water flows for supplying the slurry containing the organic granular substances into the cylindrical wall, wherein the organic granular substances are shattered into particulates including ultrafine ones of micrometer sizes at least by means of shearing-action created between the high-speed water flows and wherein the slot-like nozzle is fixedly secured to the inside cylindrical wall forming the annular passages so that a slurry supply opening is provided inside the cylindrical wall, and the annular passage is provided with a discharge port for discharging a portion of the high-speed water flows.
