The present invention relates to a multi-stage earthworm breeding device and an organic waste treatment system using the same, and more particularly, a multi-stage structure of a drawer type can be used to breed a large amount of earthworms with a minimum area and a small number of people, and is particularly installed underground. As it is easy to manage temperature and humidity, it is possible to breed earthworms under the optimal environmental conditions regardless of the season.The facility investment cost and operation maintenance cost are low, so it is possible to secure better site efficiency and labor cost efficiency than the existing earthworm breeding method. The present invention relates to a multi-stage earthworm breeding device and an organic waste treatment system using the same.

In general, the technology for stabilizing organic waste using the physiological characteristics of earthworms is very favorable in terms of recycling of waste resources and environmental protection, and is actively being performed both domestically and globally.

Earthworms are fed by 80-120% of their weight and excreted feces.

When breeding earthworms, supplying organic wastes such as food waste as earthworm food can easily treat the organic wastes without environmental pollution, and the raised earthworms can be used as medicinal, fishing rice, animal feed, industrial products, etc. In addition, the fecal soil generated by the earthworm can be used as agricultural fertilizer.

6 shows a process for treating organic waste using such a conventional earthworm. As can be seen in Figure 6, conventionally when composting by using an earthworm among the various methods of composting organic waste, such as food waste, the following process is used.

In other words, organic wastes such as food waste are put into the input facility → sorting of metals, vinyl, plastics, etc. in the sorting facility → shredding the selected organic wastes in the shredding facility → dehydrated organic wastes in the dehydration facility → aerobic in the fermentation facility Fermentation → It is composted through the process of using earthworm breeding facilities.

At this time, the wastewater discharged from the dewatering facility is usually sent to the sewage treatment plant via the leachate storage tank, the earthworm breeding facility is able to produce earthworms and fecal soil.

However, although the technology for treating organic waste using earthworms has been settled in Korea to some extent, most of the methods of simply stocking earthworms in an open field or a vinyl house and inputting organic waste are treated.

This conventional earthworm breeding method has a lot of problems, such as a very large site and a lot of manpower and equipment.

5 is a perspective view showing an organic waste treatment system using a multi-stage earthworm breeding device according to the present invention.

As shown in Fig. 5, it is most important to keep the four environmental conditions of temperature, humidity, ventilation, and light optimally in the worm breeding.

To this end, the organic waste treatment system using a multi-stage earthworm breeding device provided in the present invention is an underground structure 23 built in the basement 13 of the earthworm breeding device, that is, a plurality of breeding boxes about 5 to 6m underground. Install on.

The underground structure 23, which is an underground space where earthworms are bred, includes gas in the underground breeding space such as carbon dioxide generated by the earthworm, an intake port 22 for introducing external air, a heating pipe 28 for temperature control in winter, and an earthworm. A discharge port 27 for discharging is provided.

Here, the intake port 22 is for introducing fresh air from the outside, and the heating pipe 28 is supplied with a warm air, etc. from an external boiler or the like, especially when it is necessary to adjust the temperature, such as in winter (20 to 25 ° C.), and the outlet 27 is for discharging gas generated in the underground space to the outside through a fan or the like.

The underground space where the earthworm breeding device is installed is a closed space, except for an entrance (not shown), and is made of a closed structure.

Thus, by installing the earthworm breeding device in the underground space, it is possible to more easily maintain the temperature or humidity associated with the earthworm breeding environment.

For example, in the 5-6m underground, the annual average temperature is maintained at about 15-18 ° C. Therefore, the temperature and humidity can be more easily managed by an air conditioning system. Especially, since it is located in the basement rather than the ground, there is an advantage in shading. .

The method of controlling temperature and humidity using such an air conditioning apparatus is not particularly limited and may be adopted as long as it is a method commonly known in the art.

Each breeding box 10 installed in the main body 13 in a drawer-type multi-stage structure is accommodated one by one, and in one embodiment of the present invention, two-row breeding box 10 is provided.

The rows and stages of these breeding boxes may vary depending on the size of the earthworm breeding.

When the earth box and the organic waste are filled in the breeding box 10, usually 7 to 10 days after the organic waste is added, fecal soil is made due to the active activity of the earthworm.

The earthworm breeding device of the present invention is characterized by being able to breed the earthworm more efficiently by drawing the breeding box 10 in both directions.

In other words, at first, the organic waste is put into only one of the two part boxes to raise the earthworms.

Then, after about 7 to 10 days, the fecal soil is made by the growth activity of the earthworm, so the organic waste is put into the other box that was empty at this time.

When this new organic waste is put in, the earthworms gather here, all the earthworms are moved, and then the feces soil is taken out and the feces soils are collected.

In this way, by repeatedly removing the breeding box to both sides to collect the feces of the earthworm-free side, it becomes easier to collect feces soil work.

In other words, the fecal soil can be collected simply by pouring the contents of the box as it is without the inconvenience of sorting the earthworm separately, so that the operation such as feeding the earthworm or collecting the fecal soil can be performed more easily with less personnel.

The foregoing has described the present invention with reference to the examples, and the present invention is not limited to the above-described examples, and the rights of the present invention are determined according to the appended claims. In addition, various modifications of the present invention can be carried out by those skilled in the art, but it is obvious that all belong to the scope of the present invention.

As described above, the multi-stage earthworm breeding device and the organic waste treatment system using the same have the following advantages.

First, by adopting the multi-stage multi-layered earthworm breeding ground instead of the flat one-layer structure, it is possible to solve the biggest shortcomings of the existing 'organic waste treatment facility using the earthworm' and to enable rapid mass processing.

Secondly, it is possible to intensively breed a large number of earthworms on a small site and to drastically reduce the number of management personnel who work on feeding the earthworms, collecting feces, and managing the box.

Third, in the case of the existing treatment facilities, the activity of the nocturnal earthworm is low due to the low shading effect during the day, but in the present invention, by adopting the underground structure and the multi-layer structure, it is possible to obtain a reliable shading effect during the day, therefore, the activity of the earthworm ㆍ The same can be increased at night, which can further improve the processing efficiency and processing speed of organic waste.

Fourth, in the case of the existing treatment facilities, due to cost problems, do not take special measures for maintaining the temperature in the summer or winter, so the treatment efficiency is very low or not treated at all for about five to six months throughout the year, but the present invention In this case, by adopting the underground structure, it is possible to easily maintain the proper temperature as well as the humidity at a low cost, which can drastically reduce the facility investment cost and the maintenance and operation cost, and enable uniform treatment throughout the year.
