増大しているのである。(Prior Art) The flush toilet that emerged in the last century is becoming a social problem in recent years because it has misguided civilized society. That is, the average excrement per person per year is about 620 liters, and about 49,000 liters of fresh water (drinking water) is used to flush this. In this way, 80% of the amount of excrement is put into fresh water, and huge amounts of money and advanced technology are used to separate it into fresh water and waste again. The difference in water quality is far from that of fresh water that swept away water, which pollutes rivers and increases the risk of disease transmission.

れつつある。In order to overcome environmental problems due to the spread of such flush toilets, excrement should not be discharged into public water resources, but should be treated for each living unit such as homes, apartments, factories, etc., in order to decentralize the treatment system. Various types of purification equipment have been developed and are being put into practical use, including those in Western countries, although they are localized.

ている。The pump-up type toilet, which should be called the origin of decentralization of the above processing system, produces nightmares in the toilet bowl and produces an odor due to anaerobic fermentation. Making it worse. Moreover, it cannot be completely cleared even if the number of times of drawing is increased. Therefore, it is well known that an aerobic bacterium or an enzyme is put into the toilet tank, air aeration is performed, and the organic matter is biochemically separated into water and carbon dioxide by the action of the enzyme and the bacterium. The aerobic digestion treatment apparatus as described in the above application, that is, as shown in FIG. 4, a closed-type domestic excrement digestion tank 1, an air diffuser 2 installed near the bottom of the tank, and an exhaust hole at the top of the tank. De-cylinder 4 that rises from 3 and is released to the outside air 4
And a purifying device having an injecting means 5 for injecting air into the air diffusing pipe 2 is practically used, for example, in combination with a simple flush toilet in an area where there is no discharge destination. There is. In the figure, 6 is an automatic opening and closing type toilet equipped with an auto flapper, which also serves as an inlet for seed bacteria, enzymes, etc., 7 is a disinfection zone, 8 is an intermediate ventilation fan, 9 is a ventilator, and 10 is an overflow pipe. Such a device does not generate a foul odor, and has attracted the attention of experts as one of the most promising pollution-free cleaning devices that should replace the flush toilet in the future.
（発明が解決しようとする問題点） ところが、前記好気性消化分解に必要な空気量は一般

２回／月の頻度で汲取る必要がある等の欠点がある。(Trying invention solve that problem) However, the aerobic air amount required for digestion decomposition is generally in the following general sewage BOD200ppm a 7~10m 3 / m 3 / hr, with a high BOD of about 7000ppm About 1000 m 3 for human waste
Although aeration of / m 3 / hr is required, adding a large amount of air in an ordinary toilet tank increases the digestive ability by adding a large amount of aerobic inoculum, etc. Even if the required air volume is reduced, it is impossible at all, and only 1/3 to 1/10 of the normal required air volume can be supplied. Therefore, it cannot be said that the decomposition reaction of the organic matter is sufficient, and not only the odor cannot be completely removed, but also the treatment is insufficient, so that the residual deposit is
There are drawbacks such as the need to collect twice a month.

実用的とは云い難い。In order to increase the amount of aeration, in addition to air diffusion from the bottom of the tank, the method to circulate the liquid to be treated in the upper sprinkling pipe and spraying from the upper part of the tank is also used for industrial wastewater treatment and sewage treatment plants. However, in order to achieve sufficient enzyme absorption, a considerably large amount of circulating fluid is required, and therefore, a normal stool tank with a large undigested solids content may require pipes or nozzles to be blocked. Therefore, it is difficult to apply, and even if they can be solved, it is hardly practical in terms of noise and required power cost.

完全放流防止は程遠いという難点がある。Further, in the conventionally known aerobic digestion treatment tank for living excrement as shown in FIG. 4 described above, since the discharge is only by vaporization and evaporation at the gas-liquid contact interface, even if the gas-liquid contact interface is increased by aeration, In humid areas such as Japan, the amount of transpiration is limited to a small amount, and it is impossible to control the amount of transpiration to match the change in the amount of excrement input. Therefore, if a large amount of waste is temporarily input, the balance with transpiration and discharge will be lost, and the storage amount will naturally increase, causing sewage to overflow from the toilet tank.

As described above, the vaporized effluent of the clear water is partially recondensed and liquefied and recirculated on the inner wall surface of the de-cylinder while being discharged to the outside air through the de-cylinder 4 as described above. Return to digestion tank 1. Condensed water that condenses after passing through the disinfection zone 7 and then flows back through the disinfection zone brings in a large amount of absorbed disinfectant components into the digestion tank, so that bacteria and enzyme bacteria in the tank are killed. It has a drawback that it greatly hinders the growth and inactivates it. The amount of condensed water produced is approximately 40% of the total transpiration amount.
It is ~ 50%, and reaches about 60-70% when the outside temperature drops in winter.

境上の問題があるためにかならずしも適当ではない。The atomizing means is a means for dividing the liquid into fine mist droplets, for example, one that utilizes ultrasonic vibration, an atomizer that atomizes the liquid from the pores using a jet stream, a damper or a sprinkler, and It can be embodied by heating and boiling. Among these, an atomizer of a type widely marketed as a so-called ultrasonic type humidifier, that is, a liquid which is sequentially supplied from a closed tank 21 to a water tank 22 through a flow control valve 23 as shown in FIG. Is atomized by the ultrasonic transducer 24, and the top opening 26 of the atomization chamber 25 is
The more discharged type atomizer is most suitable because it does not generate noise, consumes a significantly small amount of power, and is capable of extremely fine atomization. Such an atomizer consumes 40 to 60 power for an average household with about 4 residents.
w, the amount of atomization of about 0.4 to 0.6 / hr is sufficient, but it goes without saying that it should be increased or decreased as necessary. The fog droplets formed by the atomizer, damper, sprinkler, etc. are considerably larger than the size of the fog droplets by ultrasonic waves, and some noise is inevitably generated by the injection, and the load on the compressor etc. increases. It is also disadvantageous to economic drops. Further, the vaporization by heating and boiling is not always suitable because it requires a large amount of latent heat of vaporization to consume a large amount of electric heat or other electric power or fuel, and has safety problems such as fire prevention and environmental problems such as odor generation.

In the figure, the supernatant liquid aerated and digested in the digestion tank 1 enters the digestion liquid storage tank 16 through the overflow pipe. The liquid sending means 13 is arranged so as to supply the digestive liquid in the reservoir 16 to the atomizing means 12. In such a specific example, a more preferable embodiment is provided with a conduit 17 for collecting the condensed water flowing back in the de-cylinder and immediately before or immediately before the disinfection zone 7 and returning it to the reservoir 16.

In addition to performing the conventional level control of controlling, the atomizing means is also provided with an organic automatic control mechanism for controlling the atomizing action by providing the means 27 for detecting the water level in the closed tank 21 of the second head, for example. Such an automatic control mechanism could be suitably designed by known and conventional techniques.

もない。Further, digestion of domestic excrement in the device of the present invention is due to the action of aerobic bacteria or enzymes, and it is most desirable to provide a means for keeping the temperature in the tank at a suitable action temperature thereof, for example, about 30 to 40 ° C. Since the digestion tank is usually buried in the ground, it is maintained at a temperature near the appropriate temperature, but in order to keep the digestion tank warm in preparation for the winter season especially in cold regions, a well-known conventional method is used inside or along the circumference of the tank wall. Consideration is required such that an appropriate heating means, for example, a plate heater is embedded or attached and an electric circuit for temperature control is incorporated. It goes without saying that a heat medium such as steam or hot water can be used instead of electric heat.
また上記槽内加熱手段としては予め加熱域を通して加
熱した空気を以って曝気することも有効である。Further, as the above-mentioned heating means in the tank, it is also effective to aerate with air which has been heated in advance through a heating zone.

分に賄いきれず、分解速度は低く抑えられる。First, an appropriate amount of a commercially available aerobic enzyme, bacteria, or the like is input from the input port 6 to living excrements such as sewage and human waste accumulated and stored in the digestion tank 1. Next, the air supply means 5 such as a compressor is operated to operate the nozzle 11 of the air diffuser 2.
If aerated rather than aeration, oxygen in the air is dissolved in the substrate in the excrement to activate the action of the aerobic enzyme and activate the growth of microorganisms. Decompose into and. However, as described above, since human excrement such as human waste has a remarkably high BOD, the amount of oxygen required for the enzyme or aerobic microorganism cannot be sufficiently covered only by the aeration action from the air diffuser, and the decomposition rate can be kept low.

活性を増進し、微生物増殖を促進するのに役立つ。Therefore, in the device of the present invention, the supernatant liquid generated by decomposing the organic matter by the digestive action of the aerobic microorganisms, the liquid supply means 13 such as a pump is operated, the atomization means 12 such as ultrasonic atomization. Introduce a vessel and atomize it finely. Since the specific surface area of the liquid is extremely increased by atomization, oxygen absorption from a large gas-liquid contact interface is remarkably promoted, and fog droplets in which a large amount of oxygen is dissolved are formed. Since the air flow from the digestion tank to the outside is formed in the de-cylinder 4 by the action of the intermediate ventilation fan 8, the atomized material generated by the atomizing means is the conduit 14
And is sent to the de-cylinder 4, and a part thereof is condensed on the inner wall of the de-cylinder and recirculates into the digestion tank 1 along the inner wall. As described above, a large amount of oxygen is dissolved in the reflux liquid, so oxygen is efficiently replenished in the digestion tank, which is aerobic in combination with the aeration action from the tank bottom and the properly maintained tank temperature.

It is possible to significantly reduce the number of times of collecting the residual sediment derived from the conventional insufficient processing amount. That is, the conventional pumping frequency of 1 to 2 times per month is reduced to 1 in 2 to 4 years by simply pumping away residues of watermelon seeds, rubber products, etc. which cannot be digested by the device of the present invention.
It can be reduced to about once, and the generated odor can be suppressed by complete reaction to achieve deodorization. Also, if an ultrasonic atomizer is applied, the effluent of the digestive juices will be evaporated without causing a substantial increase in noise and power consumption, and without the risk of fire and outbreak of pathogenic bacteria such as disaster prevention and hygiene. The amount can be increased.
