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 flexibility. 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.

  The upper end 35b of the pumping pipe 35 is connected to one sprinkling pipe 50 via a hose 36 having a required length. The sprinkling pipe 50 is provided with a large number of sprinkling holes 50a for sprinkling sewage from the pumping pipe 35 onto the surface of the filter medium 40 along the longitudinal direction, and the tip is closed. An adjustment valve 51 that adjusts the amount of sewage sprayed from the sprinkling pipe 50 is grounded at an intermediate portion of the pumping pipe 35.

A nut bracket 52 is integrally fixed to an intermediate portion of the watering pipe 50, and a roller 53 is attached to the closed end.
On the other hand, a cover plate 54 is detachably installed in the upper surface opening 12 a of the upper tank 12. Fixed to the cover plate 54 is a motor 55, a gear 56, a control circuit (not shown) that controls forward / reverse switching of the rotation of the motor 55, a drive box 60 that incorporates a bearing (not shown), and the like. A screw rod 61 is rotatably mounted on the drive box 60 by a bearing (not shown), and the screw rod 61 and the drive shaft of the motor 55 are connected via a gear 56. The screw rod 61 is screwed into the nut bracket 52 of the water spray pipe 50 so as to be rotatable.

A rail member 62 is attached to the cover plate 54, and the roller 53 of the water spray pipe 50 is grounded to the rail member 62 so as to be rotatable. Thus, the water spray pipe 50 is attached to the housing 11 by the nut bracket 52 and the rail member 62 so as to be movable along the screw rod 61 above the filter medium 40. The screw rod 50 is constructed from one end of the filter medium 40 to the other end.
Furthermore, a pair of limit switches 63 and 64 are fixed to the cover plate 54. The limit switches 63 and 64 are opened and closed when the nut bracket 52 is brought into and out of contact. As the limit switches 63 and 64 are opened and closed, the rotation of the motor 55 is controlled to be switched between forward and reverse.

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 sprinkled on the surface of the filter medium 40 through the sprinkling holes 50 a of the sprinkling pipe 50. The amount of sprinkling at this time is adjusted by the adjustment valve 51 so as to be an appropriate amount according to the filtration capacity of the filter medium 40. Further, when watering, the motor 55 is energized and the screw rod 61 is rotated. As the screw rod 61 rotates, the sprinkling pipe 50 moves along the screw rod 61. When the sprinkling pipe 50 moves in one direction by a predetermined amount, the nut bracket 52 hits the limit switch 64 and the rotation direction of the motor 55 is switched, so that the sprinkling pipe 50 moves in the reverse direction. When the nut bracket 52 hits the limit switch 63, the rotation direction of the motor 55 is switched again. Thus, the sprinkling pipe 50 repeats reciprocating movement above the filter medium 40, and the sewage is uniformly sprayed on the surface of the filter medium 40 from the water spray holes 50a. Then, it is filtered by the filter medium 40 to remove impurities such as harmful substances and drained from the water outlet 20 through the switching valve 21 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 using moisture as a medium on the surface and hollow part of the fine pores of the porous particles or powders such as activated carbon constituting 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.

Since the sprinkling holes 50a are reciprocated above the filter medium 40, the sewage can be poured evenly onto the filter medium 40. Therefore, the filtering capacity of the filter medium 40 is more effectively exhibited.

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.
