Description

DETAILED DESCRIPTION OF THE INVENTION

[The current state of the technology related to the invention] The public's eyes on odors are becoming more severe with each passing day, so they are becoming more and more sensitive to odors and the demands are becoming stricter. In particular, since odors from garbage and animal waste are continuously generated in large amounts and are intense, they cause environmental problems in surrounding areas such as livestock farms and garbage disposal sites. In such a situation, when a large amount of a conventional deodorant having a chemical equivalent deodorizing effect is used in a large amount, it has a single effect but cannot be expected to have long-lasting effect. Furthermore, a deodorant that uses a masking action due to another odor, which is the mainstream of deodorants, has no effect even if sprayed in a large amount. Recently, there are many cases where small pets are bred indoors, and there is a great desire for a suitable deodorant. However, no satisfactory products for such uses have been supplied. The reason is that
Conventional products have a mechanism of deodorizing by adsorption to odorous substance molecules or 1: 1 chemical reaction, and there is a chemical equivalent limit to the amount of deodorant used. Based on this principle, in order to deodorize odors caused by continuous sources, it is necessary to continuously supply and react a chemical equivalent of a deodorant corresponding to the odorous substance. The amount of the deodorant, but also the continuous supply, is more difficult and consequently expensive. In addition to the properties and effects of the deodorant itself, there are various problems and anxiety such as safety, so that it can be declared that there is practically no material that can withstand practical use.

[PROBLEMS TO BE SOLVED BY THE INVENTION] A material and a method for safely, simply and inexpensively preventing odors that continuously occur are provided.

When odor is generated continuously and in a large amount, it is considered to be impractical other than to control the generation of odor by acting on the source itself. If such a method is used, it is considered that the generation of odor can be continuously prevented theoretically by a temporary treatment even if the amount is small. If this method is realized, there is a possibility that the method can be applied to a case where a substantially constant amount of odorous substances is emitted every day, such as livestock.

Problem I: Most of the odorous substances emitted from sources such as garbage and animal dung are nitrogen compounds. Therefore,
The first goal is achieved if the nitrogen compound, which is the odor source, can be decomposed so as not to generate odor. Although it has already been mentioned that the stoichiometric method is not suitable as a decomposition method, it is easy, safe and inexpensive to use microorganisms for continuous and continuous operation.

Problem II Specifically, a method is considered in which compost indispensable for agriculture is produced, and Bacillus subtilis or the like is caused to act on the caustic nitrogen compound in an aerobic state to consume substances causing odor. Generally, in the process of composting, carbon compounds, such as grass, trees, and fallen leaves, are mixed with animal dung, which is a nitrogen compound. Microbes mainly consume nitrogen compounds, and carbon compounds are enzymes that are produced by the microorganisms. Is considered to be decomposed into humus and the composting proceeds, but in terms of the ratio of wood and nitrogen, when the ratio of carbon is overwhelmingly large, the nitrogen is digested quickly, and during this time the odor is almost eliminated. It has been repeatedly confirmed experimentally that this does not occur. If this mechanism is utilized, it should be possible in principle to continuously treat a large amount of nitrogen compounds, which are substances causing odor.

Problem III To make the most of the above mechanism, it was found by comparison experiments on various samples having different surface states that the properties of the woody surface as a carbon compound raw material were important. Experiments have shown that those that have been finely ground to crush the wood tissue generally have shown good reactivity, but the fineness that was cut at the same fineness was not effective. The reason is considered as follows. That is, as can be seen by observing with a microscope, the cross section cut with a blade is a smooth surface in which the tissue remains orderly. On the other hand, the crushed material has cracks running along the fibers, and the tissue is finely broken. Although woody materials originally have resistance to microorganisms, apart from the essential oil components, the essence of resistance is thought to be that cellulose lignin, which is the main component, forms a eutectic structure. Therefore, if the crushed surface is processed in a state where the crystal structure is preserved, it is natural that sufficient resistance remains, and the effect of fineness is equivalent to no effect. Fineness is a measure of the microorganisms that work, and it makes no sense to discuss it on a human scale. The details are often misunderstood, so it is emphasized here. Based on the above considerations, it is presumed that it is important to crush the crystal structure so as to break it, and it is theorized that the best properties can be obtained from such crushed samples as an experimental result. Consistency is completely established. A crushing method which is well suited to this principle is a method of crushing tree tissue while crushing it, and such crushing devices actually exist.

IV of the Problem It is necessary to specify at what point in the process of composting wood and how and how to use the deodorizing action. According to experiments, well-crushed wood has a deodorizing effect under certain conditions of use without composting. No significant effect on odor was observed. The same composting treatment can result in significant differences in the resulting deodorant properties, so it can be considered that the key to producing the effect is not in the composting process but in crushing. However, those that became anaerobic during the composting process or that contained excessive moisture, even if subjected to good crushing, cannot be expected to have a deodorizing effect, and it is difficult to recover the deodorizing effect. . The meaning of the state of crushing is to be interpreted as meaning that the density of the effective woody surface per unit volume (in other words, of the crushed surface rather than the crystallographic surface) is an important factor. Under such a premise, it is difficult to generally specify the practically usable state, but all the products manufactured according to the essential points specified in the problems 1 to 4 have a deodorizing effect.

[Note 1] Although wood and wood materials are grass and trees,
Tree leaves may even inhibit the deodorant function beyond the purpose of the present invention, and it is desirable to remove them as much as possible.

[Note 2] It is inevitable to use extremely multifunctional and safe Bacillus subtilis as a microorganism used for composting.

[Note 3] In the process of composting wood, adding various nitrogen components for the purpose of promoting fermentation is very effective in any case. It is desirable to reduce nitrogen components other than microorganisms as much as possible.

[Note 4] The most desirable woody species is hardwood. Although it is not impossible with conifers, composting is difficult due to the essential oil components and the like contained in the wood, and it is difficult to produce products that exhibit high effects. If conifers must be used, the crushed wood should be treated with mild caustic or exposed to open-air for a long time before composting.

[Note 5] To preserve the composted wood, it is necessary to dry it as much as possible. It is important to keep in mind that insufficient drying leads to degradation of the humus and less deodorizing effect. Conversely, when used, adjust the humidity appropriately. If there is no moisture, the deodorizing effect is weak.

[Note 6] Although there is no particular place to be specified as the method of use, it is effective immediately if placed in direct contact with odorous substances.
In some cases, the effect can be exerted simply by placing it on the periphery.
