  The present invention relates to a water treatment apparatus that purifies and discharges waste water after separating the waste from waste water containing garbage such as raw garbage and butts.

  Conventionally, ashtrays installed in public smoking spaces such as station platforms, pachinko parlors, hotel lobbies, etc. have fire extinguishing water stored at the bottom of the ashtrays to ensure that the cigarettes are extinguished. There may be. Therefore, when the ashtray is collected, sewage containing a large amount of tar, nicotine and the like dissolved from the butts is collected together with the butts. If this sewage flows directly into sewage or rivers, it will cause environmental pollution.

  In addition, raw garbage generated in campsites, kitchens, homes, and the like is discarded after draining water with a colander or net to remove water from the raw garbage as much as possible. However, small tea shells, pieces of food, and rice sharpening juice that pass through the eyes of colander and nets are washed away into sewage. Especially in campsites, these fine trash will flow directly to the upstream of rivers, lakes, seas, etc. without going through the sewage treatment plant. Therefore, there is a possibility that a place for enjoying nature is a place where environmental pollution such as water pollution and soil pollution occurs.

Here, in order to process a mixture of cigarette butts and water, a tank having an openable and closable drain port, and a butterfly filter disposed above the tank and allowing only the water of the mixture to pass through the tank. And a sewage filter filled with a cartridge filter, a pump, a dust removal filter disposed between the tank and the pump, and a filtered water pipe. A utility model registration No. 3136031 Is disclosed.
The pump of the butt-treating device sucks water in the tank from the lower part of the tank and feeds the water into the sewage filter from below the sewage filter. And the said water which passed the said sewage filter is discharged | emitted from the upper direction of the said sewage filter, and is returned to the said tank again through the said filtrate water pipe.

The filter medium is formed by storing porous particles or powders made of activated carbon, zeolite, etc. in a bag or case, etc., and a plurality of fine particles included in the porous particles or powders. Toxic substances contained in sewage can be adsorbed in the holes.
A switching valve 21 is provided at the water outlet 20, and a drain pipe 22 and a circulation pipe 23 are connected thereto. The switching valve 21 can be switched to the drain pipe 22 side or the circulation pipe 23 side, and can also be closed.
A hose 24 is connected to the tip of the circulation pipe 23. Thereby, even when the lower tank 15 is pulled out, the purified water can be circulated from the circulation pipe 23 onto the collection filter 30.

The lower tank 15 has a dust input port 25 formed at the upper end surface and a water intake port 26 formed at the lower part. A pump 27 is provided in the vicinity of the water intake 26 of the lower tank 15.
A collection filter 30 is fitted in the insertion port 25. The collection filter 30 is formed by storing a primary filter 32 and a secondary filter 33 in a filter storage box 31 in an overlapping manner.
The filter storage box 31 is made of metal, synthetic resin, or the like, has a flange at the mouth edge, and has a plurality of through holes on the bottom and side surfaces.
The primary filter 32 is made of a synthetic resin net, filter paper, or the like, and is formed into a sheet shape or a bag shape having approximately the same size as the filter storage box 31. Thereby, the collected garbage can be disposed of together.
The secondary filter 33 is made of a nonwoven fabric, a HEPA filter, or the like, and is formed in a mattress shape by laminating a plurality of sheets. The secondary filter 33 is formed in substantially the same area as the bottom surface of the filter storage box 31, and is laid on the bottom surface of the filter storage box 31. As a result, fine garbage that has been missed by the primary filter 32 can be collected.
Here, the HEPA filter is a high-performance air filter capable of collecting almost all fine particles having a particle size of about 3 micrometers used in air purifiers, etc. Charcoal, ash and other garbage can be collected. In addition, the secondary filter 33 is not restricted to what is formed from the said HEPA filter, a nonwoven fabric, etc., You may comprise with the member which can reproduce | recover collection ability by washing | cleaning etc.

One end 35 a of a pumping pipe 35 is connected to the water intake 26 via a pump 27. The other end 35 b of the pumping pipe 35 extends to the upper end surface of the upper tank 12.
The pumping pipe 35 is formed of a hose having plasticity and stretchability. Therefore, when the lower tank 15 is pulled out from the housing 11, the one end 35 a of the pumping pipe 35 is also pulled out according to the lower tank 15. A hose-shaped pumping tube may be wound around a reel and stored in the space 13.
Further, a bag body (not shown) provided with a plurality of small holes may be attached to the other end 35 b of the pumping pipe 35. By doing so, the momentum of the pumped sewage can be weakened and poured into the upper tank 12, and the sewage can be evenly distributed in the upper tank 12 by weakening the momentum of the water injection.

The water treatment apparatus 10 configured as described above is used as follows.
When garbage is thrown into the inlet 25 of the water treatment apparatus 10, sewage mixed with the garbage passes through the collection filter 30 and is stored in the lower tank 15. The sewage is pumped by the pump 27 to the upper end of the upper tank 12 through the pumping pipe 35.
The sewage poured into the upper tank 12 is evenly distributed in the upper tank 12 and is filtered by the filter medium filled in the upper tank 12 to remove impurities such as harmful substances. It is drained through or circulated to the lower tank 15.

The introduced garbage is collected by the collection filter 30. At this time, of the garbage, relatively large items such as butts or pieces of food are collected by the primary filter 32. Next, fine garbage that has not been collected by the primary filter 32 such as cigarette ash or unabsorbed leaves and tea leaves is collected by the secondary filter 33.
As a result, impurities such as toxic water, such as nicotine and tar, contained in the butts, or nutrients eluted from the chips of the food, sewage containing rice sharpening juice, tea, juice, etc. are collected. Is stored in the lower tank 15.

The garbage collected by the primary filter 32 can be disposed of together with the primary filter 32. Therefore, it does not take time to dispose of garbage.
In addition, when the secondary filter 33 that collects fine garbage is clogged or the like and the collection ability is reduced, the collection ability can be regenerated by washing or the like, and should be disposed of as it is. You can also.

  The sewage stored in the lower tank 15 is pumped into the upper tank 12 filled with the filter material and poured into the upper tank 12. At this time, harmful substances contained in the sewage, nutrients, rice bran, etc. are adsorbed with moisture as a medium on the surface and hollow part of the fine pores of the porous particles or powders such as activated carbon that constitute the filter medium. Is done. Thereby, the sewage which passed the upper tank 12 is discharged | emitted from the water outlet 20 as clarified purified water.

The filtered water is recirculated to the drainage or the lower tank 15.
When draining, since harmful substances and the like have already been removed from the filtered water, it does not cause environmental pollution such as water pollution and soil pollution. Therefore, in addition to being able to flow into the sewer, it is possible to flow directly into rivers, lakes, seas and the like. Furthermore, since the water treatment apparatus 10 of the present embodiment is movable, a large amount of garbage is generated as in a campsite during the season, and if the garbage is discarded as it is, it may cause environmental pollution. It can be used where there is a risk of becoming.

When circulating to the lower tank 15 again, the trash put in the filter storage box 31 is washed with purified water after filtration. Therefore, it is possible to suppress bad odors generated by garbage. Moreover, the density | concentration of the sewage thrown in from the inlet 25 becomes thin by circulating purified water. In particular, when a large amount of butts are included in the sewage, the concentration of tar in the sewage becomes low, so that the secondary filter 33 and the filter medium can be prevented from being clogged.
Furthermore, in the case of the water treatment apparatus 10 of the present embodiment, it is possible to obtain sufficiently clear purified water only by filtering the sewage once in the upper tank 12, but when it is circulated a plurality of times, it is contained in the sewage. It is possible to remove almost all impurities such as harmful substances.

According to the present embodiment, since the water treatment device 10 is divided into two tanks, an upper tank 12 and a lower tank 15, it can be reduced in size as compared with a single tank structure water treatment device having the same volume. .
In addition, since the garbage tank 25 is provided in the lower tank 15, the user does not have to lift the garbage box or the garbage bin to the upper end of the upper tank.
And since the lower tank 15 was installed so that it could be taken in and out of the space 13 provided under the upper tank 12, the water treatment apparatus 10 can be made compact.

  Further, the water treatment device 10 pumps the sewage from which the garbage has been removed in advance by the collection filter 30 of the lower tank 15 to the upper tank 12. Therefore, it is possible to prevent fine dust that causes a failure from entering the pump 27 and the pumping pipe 35.

  In addition, the pumped sewage was distributed over the entire upper tank 12 filled with the filter medium. Therefore, the filtration processing time can be shortened, and a large amount of sewage can be treated by one filtration.

In addition, casters 14 and 16 are provided at the lower part so as to be movable. Therefore, for example, a water treatment device of this embodiment is installed in a place where a large amount of butts are generated, such as a pachinko shop, or a large amount of garbage is generated in a concentrated manner during the season, such as a campsite. It can be used after being moved to a place where garbage is treated, such as being installed at a place.
Since the lower tank 15 is installed so that it can be taken in and out of the space 13, for example, when the restaurant is busy, such as a restaurant, a garbage can be thrown into the filter storage box 31 of the lower tank 15. In addition, when there is a margin in time, the lower tank 15 can be stored in the space 13 and filtered. That is, since the water treatment apparatus 10 of the present embodiment can pull out the lower tank 15 or store it in the space 13 in accordance with the purpose of use, it can improve usability.

  Moreover, the water treatment apparatus 10 of the present embodiment is configured by filling the upper tank 12 with a filter medium. For this reason, it is possible to significantly increase the filtration capacity and to treat a large amount of sewage at a time, rather than providing a filtration filter in the middle of the pumping pipe 35 or the drainage pipe 22 and the circulation pipe 23. The sewage poured into the upper tank 12 is evenly submerged in the upper tank. Therefore, the time for the filtration process can be shortened, and a rapid decrease in the adsorption capacity of the filter medium due to clogging or the like can be prevented.

It is explanatory drawing which shows the outline of the water treatment apparatus of a present Example.
