Along the inner wall surface of the anaerobic treatment area and the second pump 27 for supplying water to the washing tank 12 of the first temporary box 10 as washing water (after filtering, the water to be treated 30 is regenerated to become washing water). Based on the detection results of the voltage generation unit 28 that applies voltage to the pair of counter electrodes 28a and 28b provided so as to face each other, the detection unit 26, the human sensor 15, the storage battery unit 130 that will be described later, and the like. It includes a door lock unit 16, a display unit 17, a voltage generation unit 28, a blower 22d, and a control unit 29 that controls cleaning drive of the cleaning tank 12.

The first temporary box and the second temporary box 20 are connected between the temporary boxes via the water supply connection port 18 and the drainage connection port 19. A storage battery unit 130 is provided as a power source for driving the toilet system 1, and the storage battery unit 130 may be charged from a commercial power source or from a solar panel 131 as shown in FIG. May be good. Further, the storage battery unit 130 may be provided inside the second temporary box 20 or outside the second temporary box. The biological treatment tank 24 and the filter tank 25 are connected via an on-off valve 122, and the water to be treated 30 flows from the biological treatment tank 24 to the filter tank 25 according to the open / closed state of the on-off valve 122. An on-off valve 123 is also provided between the filter tank 25 and the second pump 27, and the cleaning water is pumped up from the filter tank 25 to the cleaning tank 12 according to the open / closed state of the on-off valve 123.

Here, the configuration of the biological treatment tank 24 will be described in detail. The aerobic treatment region 22 of the biological treatment tank 24 is divided into two compartments (first compartment 22a and second compartment 22b) via the first partition plate 31, and the first compartment 22a and the second compartment 22b. Is connected below the first partition plate 31 in a state in which the water to be treated 30 can flow. Further, the anaerobic treatment region 23 of the biological treatment tank 24 is divided into two compartments (third compartment 23a and fourth compartment 23b) via a third partition plate 33, and the third compartment 23a and the fourth compartment 23b. Is connected below the third partition plate 33 in a state in which the water to be treated 30 can flow. That is, the first section 22a and the second section 22b have the same water level, and the third section 23a and the fourth section 23b have the same water level.

Here, in order to allow the aerobic treated water 30 in the aerobic treatment region 22 to flow into the anaerobic treatment region 23 by natural flow, it is installed between the aerobic treatment region 22 and the anaerobic treatment region 23. The second partition plate 32 is installed so as to have an opening 32a for the water to be treated 30 to flow at a position lower than the height of the side wall surface of the first partition 22a and the first partition plate 31. Further, the outlet 34 for flowing out the water to be treated 30 from the fourth section 23b to the filter tank 25 so that the water 30 to be treated in the anaerobic treatment region 23 does not flow back to the aerobic treatment region 22 side is the first. 2 The partition plate 32 is installed so that the lowest position of the outlet 34 is lower than the height of the opening 32a (the lowest position of the opening 32a). That is, the maximum water level of the aerobic treatment region 22 is the same as the lowest position of the opening 32a, and the maximum water level of the anaerobic treatment region 23 is the same as the lowest position of the outlet 34. Then, by installing the lowermost position of the outflow port 34 at a position lower than the lowest position of the opening 32a, the water to be treated 30 can flow from the first section 22a to the filter tank 25 in a natural flow. it can.

On the bottom surface of the aerobic treatment region 22, an air diffuser pipe 22f for aerating with air from the blower 22d is arranged between the first compartment 22a and the second compartment 22b. Further, in the second compartment 22b of the aerobic treatment region 22 and the third compartment 23a of the anaerobic treatment region 23, an aerobic nesting portion 22e and an anaerobic nesting portion 23e for inhabiting microorganisms are arranged, respectively. The microorganisms in the second compartment 22b mainly use sufficient oxygen as energy to prey on bacteria, germs, molds, etc. attached to urine, and the microorganisms in the third compartment 23a do not have oxygen, so instead of oxygen, phosphorus and urea are used. , Potassium, etc. are decomposed and used as an energy source for biological treatment.

The aerobic nesting portion 22e and the anaerobic nesting portion 23e are not limited to such an arrangement structure, and for example, a porous material may be laid on the bottom surface portion, or a microbial nesting material may be suspended in water. Further, the air diffuser pipe 22f does not necessarily have to be arranged exactly in the middle between the first compartment 22a and the second compartment 22b as long as oxygen can be supplied to both the first compartment 22a and the second compartment 22b. Depending on the environment, it may be arranged at a position where a large amount of air is supplied to either the first section 22a side or the second section 22b side.

In the fourth section 23b, a third pump 28c for returning the water to be treated 30 in the fourth section 23b to the first section 22a is arranged. In the biological treatment from the first section 22a to the fourth section 23b, when it is judged that the treatment is not sufficiently performed, the water to be treated 30 is transferred to the first section by driving the third pump 28c. The water quality can be improved by returning it to 22a and repeating the biological treatment again.

The water to be treated 30 pumped up from the first pump 14 of the first temporary box 10 is put into the first section 22a of the biological treatment tank 22, and aerobic treatment is performed while increasing the dissolved oxygen by aeration from the air diffuser pipe 22f. move on. The charged water 30 passes under the first partition plate 31 while being aerobically treated by dissolving oxygen, flows into the second section 22b, and passes through the microbial treatment in the aerobic nesting portion 22e. It naturally flows down from the opening 32a into the third section 23a of the anaerobic treatment region 23. A large number of aerobic microorganisms are present in the aerobic nesting portion 22e, and bacteria, germs, molds and the like adhering to the human waste of the water to be treated 30 are effectively preyed on by using sufficient oxygen as energy.

The water to be treated 30 that overflows the opening 32a is anaerobically treated by microorganisms in the tank while flowing from the third compartment 23a to the fourth compartment 23b. Here, the water to be treated 30 flows quietly in a state where oxygen is not supplied, and flows out from the outlet 34 to the filter tank 25 while being anaerobically treated. Many anaerobic microorganisms are present in the anaerobic nesting portion 23e of the third compartment 23a, and as described above, biological treatment is performed by decomposing phosphorus, urea, potassium and the like instead of oxygen and using them as an energy source. To. A pair of counter electrodes 28a and 28b are arranged along the inner wall surface of the fourth compartment 23b, and a high voltage is applied between the electrodes by the voltage generating unit 28. A weak current flows between the electrodes 28a and 28b due to this voltage, and foreign matter such as dead microorganisms and flocs contained in the water to be treated 30 is adsorbed on one of the electrodes and removed from the water 30 to be treated. The high voltage makes it possible to kill various germs and eradicate them. By such treatment, the water quality of the water to be treated 30 can be improved. The water to be treated 30 electrically treated in the fourth section 23b flows from the outlet 34 into the filter tank as the water to be treated 30 to be treated next flows from the aerobic treatment region 22 to the anaerobic treatment region 23. It is leaked to 25.

Next, the configuration of the filter tank 25 will be described in detail. The filter tank 25 is divided into a fifth compartment 25a and a sixth compartment 25b, and the fifth compartment 25a has a pH adjusting region 25c in which a lime substance such as a shell is spread to adjust the pH, and a pH adjusting region 25c as an adsorbent. An adsorption region 25d covered with an activated carbon substance such as charcoal is provided, and a water quality sensor 25e for sensing water quality (for example, pH and biochemical oxygen demand (BOD)) is provided in the sixth compartment 25b. The fifth section 25a and the sixth section 25b are connected to each other so that the water to be treated 30 can flow under each tank, and the water levels of the fifth section 25a and the sixth section 25b are basically the same. However, the permeation time and the like may differ depending on the materials (for example, the above-mentioned shells, porous materials other than charcoal, sand and stones divided into a plurality of sizes, filter membranes, etc.) put into the filter tank 25. There may be times when the water levels do not match. The filtered water 30 to be treated flows into the washing tank 12 as washing water by pumping up the second pump 27.

The water quality sensor 25e preferably measures the water to be treated 30 in a state close to the washing water after each treatment, and at least the latter side of the circulation treatment in a series of purification treatment tanks, more preferably as shown in FIG. It is preferable that the filter tank 25 is arranged in the sixth compartment 25b.

The pH of the water to be treated 30 flowing into the filter tank 25 is adjusted by the shell in the pH adjusting region 25c. In developing the toilet system according to the present invention, the inventors have a weak acidity of about 5 in the pH value of the water to be treated 30 immediately before flowing into the filter tank 25 when the pH is not adjusted at all. It was confirmed experimentally that there was. At the same time, it was also experimentally confirmed that the treatment performance was improved as the water to be treated 30 was closer to neutral or weakly alkaline. Therefore, by passing the water to be treated 30 through the pH adjustment region 25c, purification treatment utilizing the porosity of the lime substance such as shells, pH adjustment with calcium carbonate, and the like are performed, and the water to be treated 30 (washing water) is performed. It is possible to bring the pH closer to alkaline while removing foreign substances from the water to be treated 30) of the entire system including the above.

Further, the water to be treated 30 comes into contact with charcoal as an adsorbent in the adsorption region 25d to remove the remaining foreign matter, decolorize the pigment contained in the urine, and / or decompose the pollutant. It is possible to regenerate high quality wash water.

In the pH adjustment region 25c, coarse shells are sequentially laminated from upper to lower (toward the flow direction of the water to be treated 30) to fine shells, and also in the adsorption region 25d, from upper to lower. It is desirable that the coarse charcoal is sequentially laminated with the fine charcoal (in the flow direction of the water 30 to be treated).

Further, as the frequency of use of the toilet system 1 increases, the amount of water in the entire system increases due to urine, washlet (registered trademark), and the like. When the amount of water increases, the cleaning tank 12 becomes full, the water level in the filter tank 25 rises, and the treated reclaimed water flows back. Therefore, a surplus water tank 121 is provided under the floor of the second temporary box 20, and the water to be treated 30 (reclaimed water) that exceeds the outlet 35 of the filter tank 25 is stored in the surplus water tank 121. The reclaimed water stored in the surplus water tank 121 may be drained to the outside as it is, or may be returned to the washing tank 12.

The lowest position of the outflow port 35 is lower than the lowest position of the outflow port 34, and the water to be treated 30 (reclaimed water) that overflows the outflow port 35 flows out to the surplus water tank 121. By doing so, the water to be treated 30 does not flow back from the filter tank 25 to the biological treatment tank 24 even when the frequency of use is high to some extent and the amount of water increases. A water level sensor 121a is provided in the surplus water tank 121, and when the detection unit 26 detects that the measurement result of the water level sensor exceeds a predetermined water level, the toilet system 1 is used as described later. May be prohibited.

The reclaimed water stored in the surplus water tank 121 may spoil over time, so it is desirable to periodically discharge it to the outside. The reclaimed water stored in the surplus water tank 121 may be discharged manually from the suction port 121b, or may be sprayed using an ultrasonic vibrator or the like and discharged to the outside. May be good.

As a result of sensing by the water quality sensor 25e of the filter tank 25, when the detection unit 26 detects that the predetermined water quality level is not satisfied (for example, the pH or BOD does not satisfy the predetermined value), the control unit 29 performs a series. The circulation treatment in the purification treatment tank is controlled. Specifically, for example, when it is detected that the water quality is poor, there is a high possibility that the treatment has been excessive (or is about to occur), so the door lock 16 of the first temporary box 10 is locked. By doing so, it is possible to prohibit the acceptance of new users, and during that time, proceed with the circulation treatment in a series of purification treatment tanks to improve the water quality. At this time, by also displaying the information to the effect that the use is prohibited on the display unit 17 of the first temporary box 10, it is possible to give advance notice of the prohibition to the person who is planning to use the box.

For example, if the water quality does not improve even after the above-mentioned prohibition of use, the filter tank 25 is clogged, the microorganism is abnormal, the sensor is abnormal, or other functional abnormality necessary for operating the system. Etc. may occur, and information indicating that maintenance is required may be displayed to the administrator together with information indicating that use is prohibited. By doing so, it is possible to reduce the management effort of the administrator.

In addition to the above, for example, the control unit 29 supplies more oxygen to the aerobic treatment region 22 by increasing the output of air by the blower 22d, and attempts to improve the water quality by increasing the efficiency of the aerobic treatment. You may do so. Further, by adjusting the voltage value and frequency of the voltage generating unit 28 by the control unit 29, it is possible to adjust the current value between the electrodes 28a and 28b and to more strongly adsorb and remove the charged foreign matter. Become. Further, the control unit 29 drives the third pump 28 arranged in the fourth section 23b to return the water to be treated 30 in the fourth section 23b to the first section 22a, so that the aerobic treatment and the anaerobic treatment are performed again. The treatment may be repeated to improve the water quality. Furthermore, the control unit 29 may drive the cleaning of the cleaning tank 12 to flow the water in the system to promote the circulation treatment. In any of the circulation controls, it is possible to further improve the water quality of the water to be treated 30.

The control unit 29 performs various controls other than the above control. For example, when the detection unit 26 detects that the water level of the water level sensor 121a of the surplus water tank 121 is equal to or higher than a predetermined value, the door lock 16 is locked as described above in order to prevent the water in the system from increasing further. The lock state is set to prohibit the use, and information indicating that the surplus water tank 121 is full is displayed on the display unit 17 to urge the administrator to perform maintenance.

If the storage battery unit 130 has a small amount of electricity remaining and it is difficult to charge it from a commercial power source, reduce the power used to drive the blower 22d and the power used to the voltage generator 28 (for example, reduce the drive time to the lower limit). It is also possible to control so as to suppress the consumption of the remaining charge (lowering, weakening the driving force, etc.). At this time, for example, the drive of the blower 22d, the voltage generating unit 28, and the door lock 16 may be controlled in consideration of the remaining charge, water quality, frequency of use, and the like. That is, if only the remaining amount of electricity is a problem, even if the water quality drops to some extent, it can be maintained in a usable state without being prohibited, or if the water quality does not meet the predetermined conditions, it is prohibited. Control to prioritize water quality improvement. At this time, if the frequency of use is low, the water quality may be improved while suppressing the power consumption of the blower 22d and the voltage generating unit 28 as much as possible (over a certain period of time). By doing so, energy saving can be realized, and even in an environment where it is difficult to secure a commercial power source, it becomes possible to independently maintain the processing.

The control unit 29 further controls the system based on the result of the motion sensor 15 installed in the temporary box 10. For example, when the door lock portion 16 is locked, it is necessary to lock the door lock portion 16 after it is confirmed by the motion sensor 15 that there is no person in the first temporary box 10. Further, the control unit 29 determines whether the user is used by stool or urine according to the time when the motion sensor 15 detects the user, and the number of times of use by stool or the number of times of continuous use exceeds a predetermined number of times. In that case, it is also possible to control the improvement of water quality as described above and control such as prohibition of use for a predetermined time.

By such control of the control unit 29, it is possible to perform an appropriate circulation treatment while grasping the water quality of the water to be treated 30 (washing water after regeneration), and the treatment is stagnant, sludge accumulation, and circulation in the overtreatment. Concerns such as deterioration of treated water (turbidity, foul odor) and transparency of reclaimed water can be eliminated.

Next, the arrangement of each processing tank in the first temporary box 10 and the second temporary box 20 will be described. FIG. 3 is a top view showing an internal arrangement configuration in the toilet system according to the present embodiment. In FIG. 3, each temporary box actually has a roof, but the top view is shown assuming that there is no roof to show the internal structure.

In FIG. 3A, the toilet bowl 11 and the cleaning tank 12 are installed in the first temporary box 10. A water supply connection port 18 and a drainage connection port 19 are installed on the wall surface of the first temporary box 10 (for example, the wall surface on the side where the second temporary box 20 is arranged), and a second connection port is provided through these connection ports. Connect to the temporary box 20. In the second temporary box 20, a biological treatment tank 24 (first section 22a) is connected and arranged through a pipe connected from the drainage connection port 19, and clockwise or counterclockwise from the first section 22a (FIG. 3 (A). ), The second section 22b, the third section 23a, and the fourth section 23b are sequentially arranged adjacent to each other via the first partition plate 31, the second partition plate 32, and the third partition plate 33. Then, the filter tank 25 is arranged adjacent to the fourth section 23b, penetrates the side wall on the side closer to the first temporary box 10 from the filter tank 25, and is connected to the cleaning tank 12 via the water supply connection port 18. ing.

FIG. 3B is almost the same as the arrangement structure of FIG. 3A, but from the aerobic processing region 22 including the first compartment 22a and the second compartment 22b, and from the third compartment 23a and the fourth compartment 23b. The anaerobic treatment region 23 is a separate tank, and the tanks are connected by a pipe. By dividing the aerobic treatment area 22 and the anaerobic treatment area 23, it is possible to maintain each of them individually.

The first temporary box 10 and the second temporary box 20 are separated from each other at the water supply connection port 18 and the drainage connection port 19, and the drainage connection port 19 of the second temporary box is connected to a discharge portion such as a public toilet to make it public. It is also possible to purify the water to be treated 30 generated in the toilet in this system with this system. Further, in addition to the public toilet, if the water to be treated 30 to be purified flows in from the drainage connection port 19, it can be applied to various contaminated water.

Further, the arrangement structure shown in FIG. 3 is merely an example, and is not limited to this arrangement structure. That is, if the tanks and devices before and after the continuous processing are arranged at positions adjacent to each other, another arrangement structure may be used.

Further, instead of the electrodes 28a and 28b and the voltage generating portion 28 arranged in the third compartment 23b, a stirrer may be provided on the bottom surface of the third compartment 23b and a flocculant may be provided in the third compartment 23b. At this time, for example, the flocculant may be stored in a water-permeable net or container and stirred by a stirrer to agglomerate suspended matter and germs contained in the water to be treated 30.

Furthermore, sensing may be performed by utilizing the fact that the conductivity between the electrodes 28a and 28b changes according to the amount of the charged foreign matter and the current flowing between the electrodes 28a and 28b changes. .. That is, even if a current measuring unit (not shown) for measuring the current value between the electrodes 28a and 28b is provided and the sensor functions as a sensor for detecting the amount of foreign matter contained in the water to be treated 30 according to the measured current value. Good. In this case, instead of the water quality sensor 25e, a sensor using the electrodes 28a and 28b and the voltage generating unit 28 may be used as the water quality sensor.

With the above configuration, it is possible to realize a completely self-treatment type toilet system. In addition, by connecting and configuring temporary toilet boxes that are generally used at construction sites, it is possible to reduce the size with a simple structure. Further, by separating the user's box and the circulation processing box, each can be maintained individually, and the work efficiency can be improved.

(Second Embodiment of the present invention)
The toilet system according to this embodiment will be described with reference to FIG. The toilet system according to the present embodiment is a modified example in which the structure of the biological treatment tank 24 in the toilet system according to the first embodiment is changed. In this embodiment, the description overlapping with the first embodiment will be omitted.

FIG. 4 is a system configuration diagram of the toilet system according to the present embodiment. In FIG. 4, what is different from the case of FIG. 2 in the first embodiment is that the first compartment 22a and the second compartment 22b face the flat membrane 210 for the membrane separation activated sludge method (MBR). A suction region 220 is provided between the electrodes 28a and 28b. It should be noted that these configurations may be provided as necessary, and may be a configuration including only the flat membrane 210, only the adsorption region 220, or both the flat membrane 210 and the adsorption region 220.

The flat membrane 210 is for performing a membrane separation activated sludge method, and the flat membrane filter can remove germs and sludge contained in the water to be treated 30.

The adsorption region 220 is formed of, for example, porous carbon so that suspended matter or the like contained in the water to be treated 30 is easily adsorbed, and a dead body of a charged microorganism is generated by a weak current flowing between the electrodes 28a and 28b. Foreign matter such as electric charge or flocs is adsorbed in the adsorption region while moving between the electrodes and can be removed from the water to be treated 30. Further, by disposing a conductive material between the electrodes, the conductivity can be increased, and power consumption can be suppressed to save energy.

As in the case of the first embodiment, the amount of the foreign matter contained in the water to be treated 30 is detected by providing a current measuring unit (not shown) for measuring the current value between the electrodes 28a and 28b. It may function as a sensor. Further, in this case, instead of the water quality sensor 25e, a sensor using the electrodes 28a and 28b and the voltage generating unit 28 may be used as the water quality sensor.

With such a configuration, it becomes possible to more reliably remove germs and suspended matter contained in the water to be treated 30 and generate high-quality reclaimed water.

(Third Embodiment of the present invention)
The toilet system according to this embodiment will be described with reference to FIG. The toilet system according to the present embodiment is a modified example in which the structure of the biological treatment tank 24 in the toilet system according to the first and second embodiments is changed. In this embodiment, the description overlapping with each of the above-described embodiments will be omitted.

FIG. 5 is a diagram showing the structure of a biological treatment tank in the toilet system according to the present embodiment. In the aerobic treatment region 22, it is desirable to allow the microorganisms to perform the decomposition treatment while supplying sufficient oxygen through the longest possible route. Therefore, as shown in FIG. 5, the first compartment 22a of the aerobic treatment region 22 is provided with a protruding body 22c that inclines downward from the inner wall surface toward the inside of the first compartment 22a. There is. A plurality of the protruding bodies 22c are arranged at different heights for the reason described later, and the tip portions of the opposing protruding bodies 22c overlap when the first compartment 22a is viewed from directly above. It is desirable that they are arranged in such a manner.

The water to be treated 30 pumped up by the first pump 14 is charged into the first compartment 22a, travels along the upper surface of the protruding body 22c, and gradually flows down below the first compartment 22a. At this time, since the protruding body 22c is arranged, the flow path of the water to be treated 30 becomes longer than in the case where it is not arranged, and the aerobic treatment time can be lengthened. Further, as shown in FIG. 3, in the present embodiment, a gap is formed on the back surface side of the protruding body 22c (the lower surface of the protruding body 22c in FIG. 5), and the blower 22d aerates the air. By accumulating the generated air in this gap (22 g of air), it is possible to increase the amount of dissolved oxygen in the water to be treated 30.

At this time, as described above, a plurality of projecting bodies 22c are arranged at different heights, and the tip portions of the opposing projecting bodies 22c are arranged so as to overlap each other when the first compartment 22a is viewed from directly above. When the air 22g overflows from the gap on the back surface side of the lower protruding body 22c, the protruding body 22c arranged directly above the air 22g serves as a stopper, and the protruding body 22c is arranged directly above the protruding body 22c. It moves and is fastened to the gap on the back side of the body 22c. By doing so, it is possible to increase the amount of oxygen in the upper region of the tank, that is, the region at the initial timing of biological treatment, while crushing the solid matter by the impact of the air rising due to buoyancy, and aerobic treatment can be performed. It will be possible to do it effectively.

The toilet system according to the present embodiment is an extension of the function of the filter tank 25 in the toilet system (toilet system shown in FIGS. 2, 4, 5, 5 and the like) according to each of the above embodiments. In this embodiment, the description overlapping with each of the above-described embodiments will be omitted.

FIG. 6 is a system configuration diagram of the toilet system according to the present embodiment. In FIG. 6, what is different from the case of FIG. 2 in the first embodiment is that 25 g of a porous material as an adsorbent (for example, an activated carbon substance such as the above-mentioned charcoal) is spread in the adsorption region 25d and is porous. A vibration device (for example, an ultrasonic generator that generates ultrasonic waves) 25f that applies vibration from the side surface to the water to be treated 30 that passes through the material is provided. Further, the vibrating device 25f is controlled by the control unit 29.

By forming the adsorption region 25d in such a configuration, residual foreign matter contained in the water to be treated 30 vibrated by the vibrating device 25f and pigment substances and pollutants contained in the urine are frequently and highly produced in the porous material. It will come into contact with the probability, and those substances will be adsorbed on the porous material, and it will be possible to regenerate higher quality wash water.

Further, the temperature control sheet 22h is controlled by the control unit 29.

Microorganisms (for example, medium-temperature bacteria) that undergo biological treatment in the biological treatment tank 24 have an appropriate temperature of 10 to 45 degrees, and are most activated in this temperature range, enabling efficient biological treatment. However, especially in cold regions where the temperature is below freezing, the temperature may be too low and the microorganisms may become inactive, resulting in an extremely low efficiency of biological treatment. Therefore, as described above, the temperature control sheet 22h warms the first section 22a of the aerobic treatment region 22 to raise the water temperature. The water to be treated 30 warmed in the first compartment 22a then moves sequentially to the second compartment 22b, the third compartment 23a, and the fourth compartment 24b, and as a result, the temperature of the entire biological treatment tank 24 rises. However, it becomes possible to activate the microorganisms in the entire biological treatment tank 24.

As described above, in the toilet system according to the present embodiment, the temperature control sheet 22h for adjusting the temperature of the water to be treated 30 in the aerobic treatment area 22 is attached to the aerobic treatment area 22 where the biological treatment is started.

It becomes possible to do it efficiently. That is, it is possible to maximize the treatment efficiency of the entire biological treatment tank 24 with the minimum necessary temperature control function.

The control unit 29 may adjust the temperature as well as ON / OFF the temperature control sheet 22h. Specifically, if the water quality is judged to be poor from the detection result of the water quality sensor 25e, the temperature is maintained at the temperature at which microorganisms are activated, and if the water quality is good, the power is turned off for power consumption or for energy-saving operation. You may switch.

Can be extended to increase the processing efficiency of biological processing. Further, with such a configuration, the weight of the second temporary box 20 can be reduced and the weight balance with the first temporary box 20 can be improved, so that a well-balanced and stable transportation is possible, for example, when transporting by a helicopter or the like. Become. Further, since the adsorption region 25d is arranged in the cleaning tank 12, maintenance of the activated carbon substance such as charcoal used as an adsorbent can be performed in the first temporary box where people can easily enter and exit and work can be performed. , Maintenance efficiency can be improved.

The adsorption region 25d and the water quality sensor 25e may be arranged in the first temporary box 10 and do not necessarily have to be installed in the cleaning tank 12.
