Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a movable unit toilet.

[0002]

2. Description of the Related Art Conventionally, there are various types of movable unit toilets used temporarily or on a temporary basis at construction work sites, outdoor event venues, disaster areas, etc., from simple pumping type to flush type. Proposed.

[0003] However, regarding the night soil treatment, all types including the flush type have a structure in which the night soil is stored in a tank built in the toilet.
Because of the restrictions on the number of employees or the need to regularly pump the human waste in the tank, it is necessary to perform detailed and cumbersome management during use and to collect the human waste in the tank. Therefore, there is a problem that the user may feel uncomfortable.

[0004]

SUMMARY OF THE INVENTION The present invention has been devised in order to solve the above-mentioned problems in the conventional unit toilet, and purifies the water with a purifying device having a built-in drainage of a flush toilet. By circulating and reusing it as water, the restrictions on the number of people used are greatly eased, and there is no need to collect human waste, the management of use is greatly reduced, and it is hygienic and user-friendly. It is an object of the present invention to provide a mobile unit toilet having a new structure that does not cause discomfort.

[0005]

SUMMARY OF THE INVENTION In order to achieve the above-mentioned object, in the mobile unit toilet of the present invention, an arbitrary number of toilet rooms 3, 3 equipped with flush toilets 5, 5 are provided under the floor 2 of the toilet. One aeration tank 8 followed by a first settling tank 11 followed by a first SS separation tank 10, a second aeration tank 13 containing wood chips carrying microorganisms obtained from the soil, and a second A sedimentation tank 15, a filtration tank 17, a third aeration tank 18 containing wood chips supporting microorganisms obtained from soil and a contact material, and then a second SS separation tank 19 and a third sedimentation tank 20 Storage tank 2 which performs ozone aeration following through
1 is provided integrally, and the wastewater containing human waste from the flush toilets 5 and 5 is flown into the first aeration tank 8 and the treated water in the storage tank 21 is pumped up. It is characterized in that it is configured to be circulated and reused as water for washing.

The mobile unit toilet of the present invention constructed as described above uses the wastewater containing human waste from the flush toilets 5, 5 in the soil in the first aeration tank 8 and the second aeration tank 13 in the purification device 4. The bioaeration based on the action of the microorganisms that propagate in the pores of the wood strip carrying the microorganisms obtained from the above can efficiently purify and generate almost no odor.

[0007] In the third aeration tank 18, purification is repeatedly performed by bioaeration and contact aeration, and ozone aeration is performed in the storage tank 21 to drain water, so that treated water without contamination can be obtained. The treated water in the storage tank 21 can be pumped up and circulated and reused as flushing water for the flush toilets 5 and 5.

[0008]

BEST MODE FOR CARRYING OUT THE INVENTION An embodiment of the present invention will be described below with reference to the drawings with reference to the drawings.
The purifying device 4 is integrally provided below.

In the toilet rooms 3, 3, flush toilets 5, 5,
Will be installed. Although the number of the toilet rooms 3 is two in this embodiment, the number of rooms is not limited, and an arbitrary number of rooms can be set as needed.

FIG. 1 shows a first embodiment, in which two toilet rooms 3, 3 are arranged adjacent to each other in the center of a floor 2 and hand washing rooms 7, 7 having wash basins 6, 6 on the outside of each room. Is formed.

FIG. 2 shows a second embodiment in which a hand-washing room 7 having wash basins 6, 6 is formed at the center on the floor 2, and toilet rooms 3, 3 are separated on both left and right sides thereof. .

In the purifying apparatus 4 under the floor 2, first, a first aeration tank 8 set to flow wastewater containing human waste from the flush toilets 5, 5 or the washbasins 6, 6 is provided with a baffle. 9 and a SS separation tank 10 for separating solid suspended matter, and are connected to a first settling tank 11 and a baffle 12 to a second aeration tank 13.

Wood chips carrying microorganisms obtained from the soil are put in the second aeration tank 13. Bioaeration is performed based on the action of microorganisms that propagate in the pores of the wood chips. Do.

The second aeration tank 13 is connected to a second settling tank 15 via a baffle 14, and the second settling tank 15 is connected to a third aeration tank 18 via a baffle 16 and a filtration tank 17.

The third aeration tank 18 is mixed with wood chips carrying microorganisms obtained from soil and a contact material, and performs bioaeration and contact aeration in parallel.

The third aeration tank 18 is connected to a storage tank 21 via an SS separation tank 19 and a sedimentation tank 20.

The storage tank 21 is provided with an ozone generator for storing treated water and draining water by aeration with ozone.

At the time of start-up, the purifying device 4 as described above is filled with water. At the time of operation, it is only necessary to replenish the water of the evaporation, and each of the aeration tanks 8, 13, 18 has a tank bottom. An air outlet is provided to perform flow aeration.

The treated water that has been purified and stored in the storage tank 21 is pumped up by a water pump and the flush toilet 5,
The water is supplied as washing water 5 and also as water in the basins 6,6.

In this way, the wastewater containing human waste from the flush toilets 5 and 5 or the washbasins 6 and 6 in the unit toilet 1 is purified by the purifier 4 and again the flushing water of the flush toilets 5 and 5. Alternatively, the water in the basins 6, 6 is repeatedly circulated and reused.

Incidentally, if necessary, a heater can be added to the purifying device 4 to prevent freezing. In addition, reference numeral 22 in FIGS. 1 and 2 denotes a step-shaped step platform used when entering and exiting the washrooms 6, and 23 denotes a machine room. The arrows in FIG. 3 indicate the flow direction, and the thick arrows indicate the case where the vehicle gets over the upper side, and the thin arrows indicate the case where the vehicle gets over the lower side.

[0022]

Since the present invention is configured as described above, it has the following effects.

Inside the unit toilet 1, the wastewater from the flush toilets 5, 5 can be purified by the built-in purifying device 4 and repeatedly circulated and reused again as the water for flushing the flush toilets 5, 5. Since it can be used, it is possible to use a large number of people, so that the restriction on the number of users is greatly eased, and at the same time, there is no need to collect human waste, so that the management for use can be greatly reduced.

Further, by incorporating the purifying device 4 in the unit toilet 1, the purifying can be performed without having a tank and storing urine, so that it can be used extremely sanitarily and without giving any discomfort. .

Also, the structure is simple and easy to manufacture, and it can be provided to the market at low cost.
