Abstract

To promote processing of both of garbage and water containing undecomposed residue with an aerobic bio-fungus.SOLUTION: When an air pump 29 is operated and an electromagnetic valve 31 is opened, air is sent to an air discharge pipe 25 via an air feed pipe 27. The air is then sent from a manifold 25b to a parallel pipe 25a and is discharged from a small hole 25c. Water W in a discharge water storage tank 23 is thereby aerated. Air discharged into the discharge water storage tank 23 floats and is discharged from a water surface. This discharged air infiltrates into a garbage decomposition treatment tank 7 through a slit-like hole 7c formed in a bottom part 7b. Thus, sufficient air is supplied to garbage D being agitated together with bio-chips B, and activity of aerobic bio-fungus becomes active to promote decomposition of the garbage D.SELECTED DRAWING: Figure 5

Description

The present invention uses a bio-bacteria to decompose cooking waste such as vegetables, meat, fish, and other food waste into a food waste decomposition treatment tank, and water containing undecomposed residues discharged from the food waste decomposition treatment tank. It relates to a swill treatment system having a wastewater storage tank to be treated.

Various devices have been proposed for treating swill, one of which uses biobacteria, and when the swill is put into the swill decomposition treatment tank, it is agitated and becomes large swill. When crushed and mixed, the decomposition of swill is promoted by the action of bio-bacteria, and finally it is decomposed into water and carbon dioxide to reduce the weight.
By the way, there is a problem that the water discharged from this type of device contains an undecomposed residue and may not meet the emission standard as it is.
The swill decomposition treatment system of Patent Document 1 includes a waste water storage tank that temporarily stores the water discharged from the swill decomposition treatment tank of the swill treatment machine and decomposes the undecomposed residue. The effluent storage tank has a water level adjustment mechanism installed inside it, and when the amount of stored water exceeds a predetermined level, it overflows to maintain the water level at a constant level, and the water level and the food waste of the swill treatment machine are maintained. By linking the water levels in the decomposition treatment tank, the water levels are the same.

The swill decomposition treatment tank 7 contains a large number of biochips B carrying aerobic biobacteria. The biochip B is sized so that it cannot pass through the slit-shaped hole 7c. The lid 5 is opened and the swill D is charged into the swill decomposition treatment tank 7. Then, the rotating shaft 9 is rotated, and the biochip B and the food waste D are stirred by the stirring arm 11 so as to be mixed.

Further, the solenoid valve 15 is opened to send water from a water supply source such as a water pipe (not shown) to the discharge pipe 13 and discharge the water from the small hole 13a, so that the biochip B and the swill D are in a water state suitable for the activity of biobacteria. To keep. The water generated by the decomposition of the swill D and the water discharged from the small hole 13a of the water discharge pipe 13 pass through the slit-shaped hole 7c and fall into the discharge water storage tank 23.

Further, since this air contains an aroma component released from the beads when passing through the container 21, it is possible to suppress an unpleasant odor in the swill decomposition treatment tank 7.

As described above, the water W in the discharge water storage tank 23 is aerated by the air discharged from the small hole 25c, which promotes the decomposition of the undecomposed residue contained in the water W. Emission standards will be met in a relatively short time.
Further, as described above, water is supplied to the discharge water storage tank 23 via the water pipe 33 and kept at a predetermined water level, and is kept at the same water level in the flow pipes 39 and 41. When the water W containing the undecomposed residue is supplied to the discharge water storage tank 23 through the slit-shaped hole 7c of the swill decomposition treatment tank 7, the water level rises, and the water level in the flow pipe 39 rises accordingly. , Water W is sent from the connecting pipe 43 to the flow pipe 41. Then, the water W is supplied from the drain pipe 35 to the sewage channel until the water level in the flow pipe 41 becomes the same as that in the flow pipe 39.
The on-off valve 37 is kept closed during the above operation, and is opened when all the water W in the drainage water storage tank 23 is discharged.
