Manure treatment device using aerobic microorganisms {EXCRETIONS TREATMENT APPARATUS BY AEROBIC MICROBE}

The present invention relates to a manure treatment device using aerobic microorganisms, and more particularly, to a manure treatment device using aerobic microorganisms that can be maximized the treatment efficiency by satisfying the optimum aerobic conditions and simple structure suitable for simple toilets and the like. .

Since simple toilets installed in parks, amusement parks, and construction sites are generally small, conventional treatment methods for storing and collecting manure are not desirable. In addition, since the simple toilet should be moved or removed as needed, it is not desirable to link with a nearby end treatment facility or to install a separate septic tank.

As such, aerobic digestion using aerobic microorganisms, which is one of biological treatments, is usefully applied as a preferable manure treatment such as a simple toilet that is small in size and easy to move. Aerobic microorganisms multiply in an aerobic state and break down the organic matter in the manure and convert it to carbon dioxide and water. The treatment using aerobic microorganisms is suitable for small-scale manure treatment such as simple toilets due to the fast reaction speed and less sludge generated, and is particularly environmentally friendly since there is no fear of contaminating the natural environment.

In order to use aerobic microorganisms, an environment capable of culturing and growing microorganisms under aerobic conditions is essential. Korea Patent Publication No. 1992-0004238 and Registration Utility Model Registration No. 20-0351775 provide microbial habitats with breathable media such as sawdust, bran, and foliar, and inject external air by embedding a blower in the medium for aerobic conditions. An apparatus is proposed. 20-0351775 also includes a device for heating by attaching a heating plate under the microbial culture medium in the fermentation chamber to maintain the proper temperature for fermentation, and drawing up the medium passing through the microbial culture medium to maintain the proper humidity required for fermentation. A device for spraying on is proposed together.

On the other hand, the Republic of Korea Utility Model Registration No. 20-0351787 has been proposed to receive the urine discharged from the urinal in the urine of urine to spread evenly over the microbial culture medium in order to increase the natural evaporation effect of moisture, Republic of Korea Patent Publication No. 10 -0488050 et al. Have proposed a device for mixing the medium with a stirrer to maximize the contact efficiency of the manure and microbial culture medium.

In order to improve the treatment efficiency in the treatment of manure using aerobic microorganisms, it is important to create an environment in which good aerobic conditions for the natural growth of aerobic microorganisms can be satisfied.

In the above-described prior art for creating an environment of aerobic conditions, the device for embedding the air intake in the microbial culture medium and injecting external air has a problem that the air intake is easily blocked by the medium so that oxygen supply is not performed smoothly, and frequent breakdowns are difficult. I have a problem. In addition, due to the different stacking height of the medium, the air is not supplied evenly and the air is supplied only to the low stacking height.In addition, in the cold winter, when the temperature is low, the cold air is not able to satisfy the aerobic condition. May inhibit the activity of microorganisms. Even if an electric heating heater is installed in the medium, cold air is directly injected, and it takes some time for the injected cold air to be warmed by the heater, which causes the activity of microorganisms to be degraded locally, thus reducing overall efficiency.

In addition, solid stool during manure stays in contact with the microorganisms while staying in the microbial culture medium, but it becomes anaerobic due to difficulty in supplying oxygen inside the large stool, and liquid urine passes rapidly through the microbial culture medium, which is a breathable medium. Therefore, the treatment efficiency of organic matter in the urine is lowered, and thus, untreated organic matter is decayed, resulting in malodors, and pathogens inhabit.

In addition, the oxygen supply device including the above-described ventilation pipe or the electric heater attached under the medium for temperature control for good fermentation conditions is frequently troubled and difficult to repair, so that the maintenance is difficult.

On the other hand, the above-described conventional agitator of the microbial culture medium is the best means to improve the treatment efficiency by contacting microorganisms and manure well, but the scale is complicated, expensive and difficult to maintain, such as troubleshooting It is not desirable for simple toilets having a small and easy to move structure.

It is an object of the present invention, in view of the above-mentioned problems of the prior art, it is easy to supply the appropriate air, to maintain the proper temperature, to maintain the appropriate humidity so that the optimum aerobic conditions required for the activation of aerobic microorganisms, It is to provide a manure treatment device using aerobic microorganisms suitable for simple toilets by constructing a system for easy maintenance.

In the manure treatment device using the aerobic microorganism according to the present invention as described above may preferably include a means for spreading the urine discharged from the urinal evenly on the upper medium.

According to the manure treatment device according to the present invention as described above, the manure falling from the urinal and / or toilet bowl is first contacted with the upper medium and the organic matter is first decomposed by the aerobic microorganism, and then passed through the upper medium. The organic matter remaining in the falling water is contacted with the lower medium to be secondarily decomposed. As such, the present invention can increase the treatment efficiency by treatment with aerobic microorganisms in two stages, and is effective in environmentally friendly treatment by storing only pure water in which organic matter is almost removed from the bottom of the treatment tank.

In addition, by the blowing means for appropriately injecting external air between the upper and lower media, the air is smoothly injected, and thus sufficient oxygen can be supplied to the aerobic microorganisms inhabiting the respective media. In particular, the injected air is diffused into the space between the upper and lower media to evenly pass through each of the media, thereby evenly supplying oxygen to the entire media. In addition, the injected air is controlled by warm air at an appropriate temperature by means of preheating to maintain the optimum temperature required for the activity of aerobic microorganisms throughout the medium regardless of the outside temperature.

In addition, according to the means for spraying the water accumulated in the bottom of the treatment tank toward the dropping point on the upper medium of the stool discharged from the toilet, the large stool is crushed into small particles by the sprayed water to the anaerobic state in the stool At the same time, the aerobic condition can be maintained by maximizing the contact efficiency of air and small particles can easily penetrate into the upper medium in the liquid phase, thereby further increasing the treatment efficiency by aerobic microorganisms.

In addition, according to the means for receiving the liquid urine discharged from the urinal evenly spread on the upper medium, the urine is evenly distributed and permeated throughout the upper or lower medium, the treatment efficiency is increased, as well as inside each medium and treatment tank It is also effective for maintaining proper humidity.
