DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for producing an artificial humus plant containing useful microorganisms. The present invention relates to an improvement in an apparatus for producing an artificial humic plant containing a useful microorganism.

[0002]

BACKGROUND OF THE INVENTION Conventionally, methods for producing an artificial humus plant include:
The technique described in JP-A-60-239380 is known. This technology is a method of producing an artificial humus plant by dehydrating humus sludge obtained from a wastewater treatment facility using soil bacteria and then fermenting the humus sludge. However, these methods require a fermentation step, and the conditions of the fermentation are strict,
It is not easy to stably produce an artificial humus with excellent functionality.

A technique using the above-mentioned humus sludge as it is as a soil conditioner is also disclosed in JP-A-5-345691. There is a problem that can not be suppressed in the long term.

On the other hand, Japanese Patent Publication No. 5-66199 discloses that
2. Description of the Related Art There is known a technology in which a sludge culture system including an absolutely anaerobic adjustment process and an aerobic culture process is introduced into a wastewater treatment process. This technique focuses on the aggregating action and the sludge-promoting action of phenol metabolites, and is provided with an adjusting step first and a culturing step later to maximize the amount of phenol metabolites. However, since this technology does not focus on useful microorganisms in humus sludge, the organic matter in the wastewater is polymerized or aggregated due to the aggregating action of phenol metabolites. , There was a risk of anaerobic.

[0005]

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a useful microorganism having high stability, which can suppress the growth of spoilage bacteria and Escherichia coli in humus sludge for a long time without using a fermentation step. An object of the present invention is to provide an apparatus for producing an artificial humic plant containing the same.

[0006]

According to the present invention, there is provided an apparatus for producing an artificial humus containing a useful microorganism according to the present invention which achieves the above object. A humus sludge having an inflow portion, having therein a filling portion filled with a solid filler eluted with a silica component, and having an aeration portion below the filling portion, and containing sporulated useful microorganisms. A first reaction tower having a take-out section for taking out, and an inflow section for introducing humus sludge containing useful spores from the take-out section of the first reaction tower, and a solid packing eluted with a silica component therein A humus containing useful microorganisms that have germinated together with a stirrer having a filling part filled with a material, and a stirrer for forming an upward flow toward the filling part below the filling part. Take out sludge Take out And characterized in that androgynous the second reaction tower having preferably characterized in that androgynous a reservoir for storing introducing humus sludge containing useful microorganisms bud from take-out portion of the second reaction column.

In a preferred embodiment of the present invention, the solid filler eluted with the silica component is a humus containing spores of a useful microorganism, or the solid filler eluted with a silica component contains a useful microorganism. And pumice crushed stones containing highly active and unstable silicates such as andesite or rhyolite in addition to spores containing spores.

According to the present invention, when organic matter-containing wastewater or organic residual sludge introduced from the biological treatment system of wastewater is introduced into the first reaction tower, the silica component is eluted from the solid filler and aerated for a long time. When the process is continued, useful microorganisms proliferate, and when the organic matter disappears, bacilli that form endospores among the useful microorganisms become spores, and humus sludge containing a lot of spores is obtained.

[0008] In addition, useful bacteria such as lactic acid bacteria and photosynthetic bacteria which do not form endospores may be included in addition to the bacilli due to the presence of the silica component. Therefore, in this specification, bacilli that form endospores are described as the main bacteria of useful microorganisms, but include other useful bacteria as long as they do not exceed the technical idea of the present invention.

[0009] The sporulated useful microorganisms are mixed with the silica component eluted from the solid filler in the second reaction tower, and are placed in an environment where useful microorganisms easily live. Further, in the second reaction tower, unlike the first reaction tower, no oxygen is supplied from the outside, so that the useful microorganisms are stimulated differently from the first reaction tower. Thus, the sporulated useful microorganisms germinate and grow as cells. The theory of the relationship between this stimulus and budding is unclear.

The humus sludge containing a large amount of useful microorganisms obtained from the second reaction tower can be used as it is as seed sludge for various wastewater treatments, fertilizer, artificial humus soil, soil improver, and after dehydration, cake. Alternatively, a dried product thereof may be used.

In addition, the humus sludge can be used as a seed fungus for composting garbage, and a humus ceramic can be formed by mixing a ceramic raw material with these humus sludge and sintering them.

As described above, according to the present invention, humus sludge can be obtained without using a fermentation step, and a large amount of useful microorganisms are contained in the humus sludge. And an artificial humic plant containing useful microorganisms having high stability can be produced.

Sent to At this time, half of the capacity of the first reaction column 1 is sent. In the second reaction tower 2, the mixture is mixed with the silica component eluted from the solid filler, placed in an environment where useful microorganisms can easily inhabit, and the sporulated useful microorganisms germinate and grow as cells.

The humus sludge containing a large amount of useful microorganisms obtained from the second reaction tower 2 may be sent to the outside of the system as it is, or may be sent to the storage tank 3 once it has been stored.

If organic matter remains in the humus sludge obtained from the second reaction tower 2, the operation can be repeated by returning to the first reaction tower 1 again.

FIG. 2 shows an example of an apparatus for repeating the operation of the first reaction column 1 and the second reaction column 2.
