【Example】

 An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 shows a schematic configuration of a garbage processing apparatus according to an embodiment of the present invention and its installed state.

Reference numeral 10 in the figure is a garbage processing device. The garbage processing device 10 is supported by a sink 11 and is arranged below the sink 12 of the sink 11. Then, one end of the discharge pipe 13 is connected to the drain port 12a of the sink 12. The discharge pipe 13 is provided with a branch portion 14 on the way and the other end is connected to the disposer 15. As shown in FIG. 2, the branch unit 14 includes a first branch port 14a and a second branch port 14b.

A switching valve 17 is provided at the first branch port 14a so that opening / closing can be controlled by an electric control means (not shown). The switching valve 17 has a flat plate shape and is openably and closably located between a solid line position and a dotted line position around a fulcrum 18 on one side. Note that the switching valve 17 may be configured to open in a double-door manner, as shown in FIG. Further, as shown in FIG. 4, the switching valve 17 is biased by the biasing member 19 and held in the closed position, and is manually moved to the two-dot chain line position against the biasing member 19 to open. It may be configured.

On the other hand, as shown in FIGS. 2 to 4, a mesh filter 20 is provided at the second branch port 14b, and one end of a bypass pipe 22 is connected through a drain trap 21 (FIG. 3 and omitted in FIG. 4). Then, the bypass flow path 23 in the bypass pipe 22 and the drain trap 21 are communicated with each other.

By the way, as shown in FIG. 1, one end of a garbage discharge pipe 26 is connected to the disposer 15. The other end of the garbage discharge pipe 26 is connected to the dehydration unit 27. The dehydration section 27 is provided with a garbage collection section 28 on the left side in the figure in a detachable manner, and one end of a waste water pipe 29 is connected to the right side in the figure. The other end of the waste water pipe 29 is connected to the waste water treatment tank 31 of the waste water treatment unit 30.

As shown in FIG. 5, the wastewater treatment tank 31 has an inflow port 31a on one side and an outflow port 31b on the other side of the lower part, and stores a microbial filter medium 32 therein. Then, one end of the drainage pipe 33 is connected to the outflow port 31b to connect the inside of the wastewater treatment tank 31 and the drainage channel 34, and the other end of the drainage pipe 33 is connected to a sewer pipe (not shown).

Further, as shown in FIG. 1, the other end of the bypass pipe 22 is connected in the middle of the drain pipe 33 to connect the bypass flow path 23 and the drain path 34.

However, in the above-mentioned garbage treatment device 10, the first branch port 14a is normally closed by the switching valve 17 as shown in FIGS. 2 to 4. When the inside of the sink 12 shown in FIG. 1 is only water, the water from the sink 12 is introduced from the second branch port 16 into the bypass flow path 23, and is drained through the bypass flow path 23 without passing through the waste water treatment section 30. Send to Route 34.

On the other hand, when the garbage such as vegetable waste is generated in the sink 12, when the power source (not shown) is turned on, the switching valve 17 is opened to the dotted line position shown in FIG. 2 to switch the outflow direction, and at the same time, the disposer 15 is turned on. And the dehydration unit 27 is driven. Then, the garbage from the sink 12 is sent to the disposer 15 together with water and is crushed there. Next, the crushed water-containing garbage is put into the dehydration section 27 through the garbage discharge pipe 26 and dehydrated there. After the dehydration, the crushed dust is sent to the collecting unit 28, and the dehydrated and separated water is poured into the wastewater treatment tank 31 through the inflow port 31a through the dirty water pipe 29. Then, the water is brought into contact with the microbial filter medium 32 to decompose and purify the organic components dissolved in the water. Then, when the inside of the wastewater treatment tank 31 is filled with the inflowing water, the treated water that has passed through the microbial filter medium 32 sequentially overflows from the outflow port 31b and is sent out through the drainage channel 34 to a sewer pipe (not shown). After that, the sludge (not shown) that settles on the bottom 31c of the wastewater treatment tank 31 during the wastewater treatment is taken out periodically as appropriate.

In the illustrated embodiment described above, the dehydrated and separated water was brought into contact with the microbial filter medium 32 to remove the organic components dissolved in the water. However, as shown in FIG. 6, an organic substance coagulant may be added to the dehydrated and separated water to remove the organic components dissolved in the water. That is, the waste water treatment tank 31 is divided by the partition wall 40 to provide a mixing chamber 41 on the side of the inflow port 31a and a settling chamber 42 on the side of the outflow port 31b, and a passage 43 at the lower part, and a passage 43 thereof. The mixing chamber 41 and the precipitation chamber 42 are communicated with each other. A stirring blade 44 is rotatably provided in the mixing chamber 41. Further, a medicine case 45 is provided on the upper portion of the mixing chamber 41 so as to communicate with the inside of the mixing chamber 41. The medicine case 45 accommodates the organic substance coagulant 46 therein and has an opening / closing valve 47 at the outlet.

Then, the water that has been dehydrated and separated is poured into the mixing chamber 41 through the inflow port 31 a, the opening / closing valve 47 is opened to add the organic coagulant 46, and the mixture is mixed by the rotating stirring blades 44 and then passed through the passage 43. It is sent to the settling chamber 42. Then, the organic matter coagulant 46 coagulates the organic matter dissolved in water to settle on the bottom of the settling chamber 42. Then, when the inside of the wastewater treatment tank 31 is filled with the flowing-in water, the supernatant treated water in the settling chamber 42 sequentially overflows from the outlet 31b and is sent out to the sewage (not shown) through the drainage path 34. After that, sludge (not shown) that settles to the bottom of the settling chamber 42 is taken out periodically as appropriate.

In all the illustrated embodiments described above, the branch portion 14 is provided between the sink 12 and the disposer 15. However, the branch part 14 may be arranged anywhere before the wastewater treatment part 30, for example, between the disposer 15 and the dehydration part 27, or between the dehydration part 27 and the wastewater treatment part 30. 14 may be arranged.

Further, in all the illustrated embodiments described above, the first branch port 14a is opened and closed by the switching valve 17, and the second branch port 14b is always opened. However, although not shown, when the first branch port 14a is closed by the switching valve 17, the second branch port 14b is opened, and when the first branch port 14a is opened, the second branch port 14b is closed by the switching valve 17. May be

[Effect of device]

 Therefore, according to this invention, in the case of raw garbage, the water dehydrated and separated in the dehydration section is guided to the wastewater treatment section, and the organic components dissolved in the water are removed before being sent out to the drainage channel. It can be cleaned and the load on the sewage treatment plant can be prevented from increasing. Further, in the case of water, it is sent from the sink to the drainage channel through the bypass flow passage and not through the wastewater treatment section, so the amount of treated water in the wastewater treatment section can be reduced and the wastewater treatment section can be miniaturized.
