[0018]

Embodiments of the present invention will be described below with reference to the accompanying drawings. First, Figure 1
FIG. 3 shows a mobile toilet system according to an embodiment of the present invention. In this figure, reference numeral 10 indicates a unit toilet formed as a unit, which constitutes a mobile toilet system. In the unit toilet 10, for example, as shown in the drawing, two small chambers 20 and 30 are formed separately from each other, and one of the small chambers 20 (left side in the figure) has a door. It is installed so that it can be opened and closed. Toilets and urinals 25 and 35 are installed in these small rooms, respectively.

In addition, as is apparent from FIGS. 2 and 3, a septic tank 40 (FIG. 1) for sewage from the unit toilet 10 is disposed alongside the unit toilet 10.
Here, for the sake of explanation, the unit toilet is shown transparently), but is placed on land without being buried in the soil. Specifically, as shown in the attached FIG. 4, the unit toilet 10 and the septic tank 40 are formed by combining a large number of angles or resin bases 51, 51 in a grid shape.
0 is formed and mounted on the gantry 50. In addition,
In the present embodiment, the septic tank 40 is installed on land behind the unit toilet 10.

According to the present invention, a sewage pump 60 driven by, for example, an electric motor is provided below the toilet unit 10, and an outlet of the sewage pump 60 is connected to an inlet of the septic tank 40. A pipe 65 is provided between them. That is, after using the toilet, the sewage flowing down together with the flush water from the toilet bowls 25 and 35 of the toilet unit 10 is pumped up by the sewage pump 60 and guided to the purification tank 40 via the pipe 65. The mobile toilet system is a so-called flush type, which is not shown here. For example, the toilet 25 of the toilet unit 10 is connected to a water supply pipe or a water pipe connected to a water supply facility such as a water supply tank. Needless to say, the cleaning water is supplied to 35.

That is, according to the mobile toilet system of the present invention, the mobile toilet system is provided below the toilet unit 10,
Since the sewage flowing from the toilet bowls 25 and 35 is guided to the septic tank 40 by the sewage pump 60, the septic tank 40 does not need to be buried in the soil as in the related art. It is only necessary to place the toilet unit 10 and the septic tank 40 on land. Therefore, troublesome work such as burying the septic tank 40 at the time of installation and excavation at the time of removal is not necessary, and the cost is low,
It is economically advantageous.

The wastewater discharged from the outlet of the septic tank 40 after the purification treatment by the septic tank 40 is provided with a sewer near the installation location of the mobile toilet system via a pipe 45. If there is, it is led to the sewer (not shown) and is drained as treated water. However, the place where such a mobile toilet system is installed is not necessarily provided with a sewer, and in such a case, drainage for wastewater treatment as shown on the right side of FIGS. It is possible to provide a soil infiltration treatment device 100 for treatment.

That is, the drainage soil infiltration apparatus 10
0, as is clear from the figure, is a hole 1 which is formed by digging a hole in the ground adjacent to the installation location of the mobile toilet system.
01 is formed. The excavation hole 101 is, for example, a flat rectangular excavation hole, and the bottom surface and the surrounding earth wall are left untouched. An inflow box 106 is buried at one end (left side in the figure) of the excavation hole 101. This inflow 10
Numeral 6 is a cubic container having a closed bottom surface, the upper surface of which is opened and closed by a lid 114, and the lid 114 is installed at the same height as the ground. And this inflow box 1
A pipe 45 is provided at 06 from the outlet of the septic tank 40.

On the other hand, an inspection cylinder 108 is set up on the other end side (right side in the figure) of the unearthed hole 101. The inspection tube 108 is a horizontal bottom tube 116 via an elbow, and this bottom tube 116 is installed at the bottom on the other end side of the unearthed hole 101. The upper end of the inspection tube 108 is normally closed by a lid.

The inside of the uncovered hole 101 is filled with a filter medium 103. The filter medium 103 is formed of a substantially ball-shaped hollow body, and has through holes 112 and 113 at positions where three central axes perpendicular to the hollow body penetrate the hollow body. The ball-shaped hollow body constituting the filter medium 103 may be a spherical ball, but is particularly preferably an elliptical ball as shown. When the filter medium 103 has an elliptical ball shape, the through holes 112 and 113
The long axis and two mutually orthogonal short axes are provided at positions penetrating the hollow body.

Such a filter medium 103 can be produced by molding using a polyethylene-based or polysterol-based resin or the like, and in particular, can be produced by recycling resin-based waste. The filter medium 103 may be a foam. Such a filter medium 103 has, for example, an outer dimension in the major axis direction of 200 mm, an outer diameter in the minor axis direction of 120 mm, and a thickness of 3 mm.
mm hollow body, into which 3φ through holes 112, 11
3 is provided.

The filter medium 103 is connected to the excavated hole 101.
For example, although not shown here, a bag-like net is prepared, and an appropriate number of filter media 1 are provided therein.
03 and the filter medium 103 together with the net
Fill into 1. The illustrated net has a bag shape with a partition at the center, and about four filter media 10 are provided on each side of the partition.
3 is stored. At this time, the filter media 103 are all in the same direction,
For example, it is housed so that its long axis side faces in a direction orthogonal to the partition of the net, and one short axis side through hole 113 is turned up and down.

Filter media 103 housed in such a net
Is filled in the excavated hole 101 as shown in FIGS. At the time of this filling, the filter medium 103 is installed so that one through hole on one short axis side faces downward. Therefore, the through hole 113 on the one short axis side of the filter medium 103 faces upward, and the other through holes 112 and 113 face laterally.
Further, the filter medium 103 is laid in the upper and lower layers in the excavation hole 101 so that the long axis of the filter medium 103 is oriented alternately in the width direction and the longitudinal direction of the excavation hole 101. Fill up.

Drilling hole 1 to a depth of about 450 mm from the ground
01 is filled with the filter medium 103, and the drainage introduction pipe 104 connected below the inflow water level of the
It is placed on the center of the filter medium 103 filled in 1. The drainage introduction pipe 104 is a perforated pipe having a large number of holes formed around the drainage introduction pipe 104, and is piped so that a slight downward slope is formed from the inflow box 105 side to the other end side of the unearthed hole 101. Finally, the filter material 103 laid in the excavation hole 101 and the drainage introduction pipe 104 arranged are buried back to the level of the ground, whereby the drainage soil infiltration apparatus 100 is completed.

In the drainage soil infiltration treatment apparatus 100 completed in this way, the drainage discharged from the land-based septic tank 40 is supplied to the inflow tank 106 through the pipe 45 serving as the inflow pipe.
And is stored there once. Here, some of the solids such as sludge settle at the bottom of the inflow box 106, so it is necessary to periodically take out and discard the precipitate at the bottom of the inflow box 106. Then, the drainage on the supernatant side exceeding the mounting height of the drainage introduction pipe 104 is guided into the unearthed hole 101 through the drainage introduction pipe 104 and discharged onto the filter medium 103 filled therein.

The effluent discharged onto the filter medium 103 penetrates downward through the net and the filter medium 103 and through the inside thereof, and the effluent comes into contact with the microorganisms attached to the filter medium 103 and the net and is contained therein. Organic matter is oxidized and decomposed. Then, it infiltrates into the soil from the bottom surface and the surrounding wall surface of the unearthed hole 101. In the drainage soil infiltration apparatus 100, since the filter medium 103 is formed of a hollow body having the through holes 112 and 113, the porosity inside the uncovered hole 101 is increased, and a large amount of wastewater per unit volume is discharged into the uncovered hole 101. Can fit. For example, when the elliptical ball-shaped filter medium 103 having the above-mentioned dimensions is used, the porosity inside the excavation hole 101 reaches about 95%, which is three times that of the drainage soil infiltration apparatus using the crushed stone filter medium. The above porosity is obtained.

As described above, the drainage flows into the excavation hole 101 and infiltrates the surrounding soil from the wall surface of the excavation hole 101, so that the amount of drainage in the excavation hole 101 fluctuates. The water level goes up and down. At this time, drainage flows into or out of the filter medium 103 through the through holes 112 and 113. That is, when the drainage in the excavation hole 101 rises,
In the inside of the filter medium 103, a total of five through holes
Drainage flows in from 12, and air is exhausted from one uppermost through hole 112. On the other hand, when the drainage in the unearthed hole 101 descends and the drainage inside the filter medium 103 decreases, the drainage is discharged outward only from the through hole 112 directly below, and a total of five through holes 112 around and immediately below. , 113 sucks air. As a result, air is discharged from the inside of the filter medium 103 and air is introduced into the inside of the filter medium 103, that is, the filter medium 10
3 Ventilation inside is performed smoothly.

As described above, when the water level of the drainage in the unearthed hole 101 rises or falls, not only the inside of the unearthed hole 101 but also the drainage inside the filter medium 103 flows in and out. Accordingly, air is discharged or sucked from the inside of the unearthed hole 101 or the filter medium 103. By repeating this, the excavation hole 101 and the filter medium 1
Since the inside of 03 is naturally ventilated, the inside of the excavation hole 101 is in an aerated state, and the action of purifying the wastewater is improved. In the state where the drainage soil infiltration apparatus 100 is used in this way, if sediment or the like accumulates at the bottom of the unearthed hole 101, the lid of the inspection cylinder 108 is opened, and the inspection cylinder 1 is opened.
From 08, insert a suction hose or the like into the bottom of the
The sediment can be sucked up together with the wastewater.

As described above, according to the drainage soil infiltration treatment apparatus 100 described above, since the porosity inside the treatment apparatus is large, a large amount of wastewater can be treated per unit volume and the surface area of the filter medium can be reduced. Since it is wide and the ventilation inside the treatment device is performed smoothly, the purification of the wastewater is performed smoothly, and the drainage soil infiltration treatment device which is hardly clogged can be obtained.

Next, the ventilation means provided in the mobile toilet system of the present invention for discharging the odor in the toilet to the outside will be described below.

FIG. 5 shows a flush toilet stool 25 installed in a small room 20 in the unit toilet 10 constituting the movable toilet system, and a low tank 70 for flowing flush water into the toilet. And a washing pipe 75 connected from the lower part of the low tank to the toilet. As shown in FIG. 5, a broken line A is provided in the middle of the cleaning pipe 75 connected to the lower part of the low tank 70 by a connection nut.
, A joint 80 called cheese or te-y is provided.

The flush pipe 75 is opened with a certain amount of flush water stored in the low tank 70 piped to the toilet 25 by pressing a knob or the like after use of the toilet. It is to be discharged through a flushing port (not shown), and to flush the excrement and to flush the toilet.
It is not usually used. Therefore, in the present invention,
The joint 80 attached to the washing pipe 75 is used to make it possible to exhaust air by utilizing the space in the pipe when the washing water is not flowing. That is, a part of the joint 80 is connected to a ventilation fan (not shown), and the odor in the toilet and the toilet can be exhausted to the outside through the cleaning port opened in the toilet 25. In other words, the unpleasant odor passes through the flush pipe 75 from the flush port of the toilet bowl 25, and is branched by the joint 80, guided to the ventilation fan, and discharged to the outside.
The toilet is made odorless, and furthermore, the user of the toilet does not care about the odor, so that only one use of washing water is required, which leads to water saving.

FIG. 6 shows a detailed internal structure of the joint 80 described above. This joint 80 will be described with reference to FIG.
2 and a water guide pipe indicated by reference numeral 83 and connected to the lower end of the water purification pipe 75. The joint main body 81 is about 10 mm larger than the outer diameter of the water guide pipe 83 at an intermediate portion thereof so that the water guide pipe 83 extending downward from the water purification pipe 75 can be housed therein.
It has a large inside diameter, and its upper and lower parts are connected and fixed to the water purification tube 75 by bag-shaped nuts 84 and 85. The branch pipe 82 for ventilation is connected to the joint body 8.
It is attached above the middle part of the length in the axial direction. Although not shown, the branch pipe 82 for ventilation is connected to a ventilation fan for discharging air by rotating a fan with an electric motor, for example, again by a bag-shaped nut 87. Further, the upper end of the water pipe 83 is connected to a washing pipe 75 connected to the lower part of the low tank 70, and the lower end has a width of 5 mm and a length of 1 mm.
Cuts of about 0 mm are formed at four locations.

The above-described mounting operation is performed first by using the joint body 81.
A water pipe 83 is inserted into the inside from above, and fixed by a nut 84 at the upper part of the joint body. At the time of fixing, a gap of 5 to 10 mm is provided between the lower end of the water pipe 83 and the 45 ° inclined portion 86 below the joint body 81 to fix the upper part of the joint body 81. The lower part is a toilet 2
The nut is connected to the water purification pipe 75 connected to No. 5. On the other hand, the ventilation branch pipe 82 is connected by a nut 87 provided at the center of the joint body 81.

In the joint 80 constructed as described above, the washing water is guided from the low tank 70 when the washing water is introduced from the low tank 70 because the joint water is used for both water introduction and ventilation. 75 to water pipe 83, joint body 81
Of the toilet 25 through the washing pipe 75 on the downstream side of the joint 80 again. The joint body 81
Because of the structure of the lower part of the water pipe and the water pipe 83, the water flow is indirect water flow. Therefore, in order to reduce the resistance in order to maintain a normal flow velocity, the lower four parts of the water pipe 83 are opened (the above cut portion). By arranging the lower part of the water pipe 83 close to the lower part of the main body 81, the flow velocity is prevented from changing, and the water is also prevented from flowing back to the branch pipe 82 for ventilation.

On the other hand, when the ventilation is performed, the washing water from the low tank 70 is not flowing, so that the odor in the toilet is sucked from the washing port of the toilet 25 and the washing pipe 75 on the downstream side is removed. Then, the air is guided to the joint 80, and further guided to the ventilation fan through the branch pipe 82 for ventilation connected to the center of the joint main body 81 to be exhausted to the outside. That is, according to such a structure, the toilet can be used in an odorless and clean environment.

In the above description, the Japanese-style toilet is particularly described in detail. However, the present invention is not limited to this, and it is possible to use a Western-style toilet. It will be apparent to those skilled in the art.
