CRUDE REFUSE TREATING DEVICE

摘要

PROBLEM TO BE SOLVED: To make it possible to effectively treat the malodors generated at the time of the treatment of crude refuse during a treatment stage by providing a water treatment tank supplied with sewage which is a supernatant liquid from a sedimentation sepn. tank with an air diffusion pipe and opening the suction part of the air diffusion pipe into the upper part of the sedimentation sepn. tank and a solid decomposition tank to suck the air. SOLUTION: The sewage is introduced from an introducing pipe 1 into the sedimentation sepn. tank 2. The sewage is temporarily stored and is subjected sedimentation sepn. in the sedimentation sepn. tank 2. The settled crude refuse is transferred by a transfer pipe 6 into the solid decomposition tank 3. On the other hand, the supernatant liquid is supplied by an advection pipe 7 into the water treatment tank 4. The settled crude refuse is subjected to a decomposition treatment by crude refuse treating materials in the solid decomposition tank 3. On the other hand, the supernatant liquid supplied to the water treatment tank 4 is subjected to the decomposition treatment of the org. matter in the supernatant liquid with aerobic microorganisms by the air diffused from the air diffusion part 9 of the air diffusion pipe 5. At this time, a pump 12 is operated to suck the air from the air suction part 10 and to diffuse the air from the air diffusion part 9 opened above the sedimentation sepn. tank 2, by which the decomposition treatment of the maldorous components is executed.
