Abstract

PROBLEM TO BE SOLVED: To provide an environment-friendly method of deodorizing livestock feces and urine for malodor of feces and urine of livestock which inhibits residential environment of residents, and makes impression to a tourist resort of tourists bad using an inexpensive organic acid of industrial waste of an area.SOLUTION: The method of deodorizing livestock feces and urine comprises as follows. Ammonia and amines of livestock feces and urine are easy to volatilize, and form malodor of environment, also the alkaline materials inhibit generation formation of microorganisms, and have a characteristic which does not decrease malodor. Therefore, the ammonia and amines are neutralized by an organic acid extracted from abandonment fruit, a fruit residue, and other industrial wastes which are produced in a region, volatilization of ammonia is suppressed and an obstacle poison of microorganism formation is deleted to decrease malodor as a result.

Description

The present invention relates to a method for neutralizing the malodor of ammonia and amines in livestock manure with organic acids produced from locally produced waste fruits, fruit residues and other industrial wastes to reduce the malodor.

In a conventional deodorizing method for odor generated from livestock manure, an industrially produced deodorant containing at least one acid selected from malic acid, citric acid, and tartaric acid lactic acid is known. (For example, see Patent Document 1)

Ammonia and amines in livestock manure not only volatilize and form a bad odor in the surrounding environment, but also have the characteristics that this alkaline substance inhibits the generation and generation of microorganisms and does not reduce the bad odor. Therefore, it was clarified how to neutralize ammonia and amines with organic acids extracted from waste fruits, fruit residues and other industrial wastes produced in the region, to eliminate toxic toxic substances and to reduce malodors as a result. To do.

However, manure of cattle, pigs, goats, chickens, cattle and other livestock, dogs, cats and other domestic animals for pets, as shown in Table 1 Odor component analysis table of livestock manure, amines, ammonia, mercaptan, sulfide It contains hydrogen and other trace components that produce odors, and amines and alkaline components of ammonia make manure alkaline and inhibit the production of yeast and lactic acid bacteria, reducing odors and reducing malodors, mercaptans, and other amines. There was a problem such as keeping holding.

This invention is made | formed in view of the above-mentioned situation, and makes it a subject to provide the deodorizing method of livestock manure which is kind to an environment.

In order to solve the above problems, the present invention proposes the following.
This is a method for deodorizing livestock manure, characterized by neutralizing amines and ammonia produced in livestock manure using organic acids of fruit juice of fruit to reduce malodor generated from livestock manure.
According to the present invention, the fruit is a pest fruit, poor growth fruit, scratch fruit, shade fruit, malformed fruit, lemon / mandarin oranges, plums / apricots, grapes acidic fruit juice with plenty of organic acids. In order to neutralize amines and ammonia, other fruit juices with low acidity such as apples, peaches, bananas, mangoes, etc. are fermented by adding yeast, and then neutralized by adding koji etc. to increase acidity. By doing so, malodor generated from livestock manure can be suppressed.
As agricultural waste other than fruit, organic acids of wood vinegar and bamboo vinegar generated in the process of producing charcoal and bamboo charcoal can be used to neutralize amines and ammonia.
In the present invention, the remaining fruit skin and pulp after squeezing fruit juice are dried and mixed with livestock manure, whereby amines and ammonia are absorbed into the skin and pulp, and malodor can be reduced by fruit enzymes.

By the way, examples of the organic acid that shows the acidity of the fruit juice of the fruit of fruit removal include citric acid, malic acid, quinic acid, and tartaric acid. Moreover, as a fruit with high acidity, lemon, apricot, Natsumikan, kiwifruit, apricot, strawberry, mandarin orange, and orange are mentioned. Among these, fruits are harvested to improve the quality of the fruits to be harvested, and most of them are composted.

When these fruits are picked, the sugar content is low and organic acids are superior. When the organic acid of the fruit at the time of fruit extraction is squeezed and added to livestock manure, it is neutralized by causing acid and alkali reactions with amines and ammonia contained in manure.

Molds in neutralized livestock manure are activated, hydrocarbons such as starch in livestock manure are decomposed to produce glucose, and the activity of yeast and lactic acid bacteria decreases drastically when alkaline, and the activity increases when it becomes acidic improves. Glucose is further decomposed by the action of yeast, and organic acids are further generated by the growth of yeast and lactic acid bacteria, thereby reducing malodor.

Juice with less acidic juice is used for neutralization by adding yeast, koji, and acetic acid bacteria to increase acidity. Grapes, oysters, bananas, melons, apples, and pears with little acid juice are excellent in sugar, and succinic acid, citric acid, malic acid, fumaric acid, and acetic acid are produced from these sugars to produce livestock manure amines, ammonia Neutralize.

When using organic acids such as wood vinegar and bamboo vinegar to neutralize amines and ammonia, a large amount of wood vinegar and bamboo vinegar are required due to low acidity, and if it causes inconvenience in the drying process of livestock manure, If necessary, use organic and inorganic acids from industrial products. However, the masking effect by the tar component odor can be expected by using wood vinegar and bamboo vinegar.

By drying the remaining fruit skin and pulp after squeezing the fruit juice, the fruit enzyme of the skin and fruit is concentrated, the malodor component is inactivated by this fruit enzyme, and the moisture content of the fruit skin and fruit is reduced. Absorbs malodorous ingredients by absorbing water from livestock manure into the skin and fruit.

Explain terms.
The organic acid of fruit juice refers to citric acid, malic acid, tartaric acid, quinic acid and the like.
Odor components generated from livestock manure differ in odor components depending on livestock, but are mainly amines, ammonia, mercaptan, hydrogen sulfide, methyl sulfide, and lower fatty acids (propionic acid, butyric acid, Normal valeric acid, isovaleric acid) is generated, so livestock manure is cut back to prevent the generation of lower fatty acids.
Wood vinegar is a dry distillation solution that is generated when wood is made into charcoal, and here also includes wood tar that sinks to the bottom of the wood vinegar. It has 400 kinds of ingredients and can be expected to have a masking effect on the odor of livestock manure.
Bamboo vinegar is a dry distillation solution that is generated when bamboo charcoal is obtained from bamboo, and here also includes bamboo tar that sinks to the bottom of the bamboo vinegar. It has 400 kinds of ingredients and can be expected to have a masking effect on the odor of livestock manure.
The components of fruit enzymes differ from fruit to fruit and have the effect of rapidly reducing malodour components in livestock manure by enzymatic reaction, but which components of fruit enzyme components decompose and inactivate which components of livestock manure odor It is not clear what to do.

Of particular concern among livestock manure is the treatment of livestock manure discharged in cowsheds, pig houses and poultry houses. The problem of bad odor of livestock manure generated at this time makes the residents and tourists around the barn feel uncomfortable and significantly deteriorates the living environment.

The characteristic of the thing called malodor is that the molecular weight of the malodorous component is small and the volatility is high. In particular, when there is no wind, the odor diffusion is suppressed, the odor concentration in the range where the odor spreads becomes high, and the problem of bad odor is realized.

In livestock manure, the most abundant amines and ammonia are acidified with organic acids obtained from fruits, which stabilizes ammonia ions and suppresses volatility, and also reduces yeast, lactic acid bacteria, and actinomycetes that promote malodor decomposition. Can be increased. Odor generation can be prevented as stable livestock manure compost.

The flow of spraying method of fruit organic acid is shown.

As shown in FIG. 1, the embodiment of the present invention needs to be promoted by bringing together a livestock breeding farmhouse in the region, an administrative organization such as a city hall, an odor reduction company, and a fruit cultivation farmhouse. This is because the spread of odors is about 20 km square, and it is not possible to cope with them by individual livestock farmers alone.

In addition, the city office as an administrative organization cannot be irrelevant because it is a problem that significantly deteriorates the living environment for local residents and the natural environment for tourism.
In addition, as an odor reduction company, various deodorization measures have been implemented, but deodorants are expensive and a large budget must be allocated for the measures, including livestock raising farmers, city halls and other administrative organizations, and odor reduction companies. The actual situation is difficult to operate.

Therefore, by effectively utilizing the wastes of fruit growers, cheap organic acids are supplied to livestock farmers to reduce the malodor of livestock manure, and livestock that is generated by livestock farmers and has difficulty in processing. By creating a cycle that supplies compost to fruit growers, each other can form an economical and effective environmental cycle.

The problem with this proposal is the supply of fruit organic acids from livestock farmers and the squeezing of organic acids from the fruit fruits of fruit farmers. Therefore, the odor reduction company squeezes the organic acid from the fruit and delivers the organic acid to the designated place of the livestock farmer, measures the odor, and reports it to the government agencies such as the city hall and the livestock farmer It is possible to clarify odor countermeasures for residents and tourists.

As shown in Table 1, the odor component of livestock manure consists of amines and ammonia, and the odor of livestock manure is from May to October when the house window is opened. Looking at the harvesting time for each fruit, plums, plums, peaches, apples in May, grapes, figs in June, oysters, tangerines in July, and strawberries in November are suitable for odor control. Done.

During this fruiting period, the odor reduction company carries the juice by bringing the juicer into the fruit farmer. As shown in Table 2, the squeezed juice can be deodorized by squeezing fruit juice from oranges, ume and grapes. Table 3 shows that the squeezed fruit skins and fruits may be dried in the vacant land of fruit farmers, and the dried fruit skins are effective in deodorizing livestock manure. In addition, the peel after squeezing may be decomposed by mixing with compost purchased from livestock breeding farmers.

The fruit organic acid is put in a tank and stored at an odor reduction company. Upon receiving a request from a livestock farmer, the odor reduction company delivers it to a designated tank of the livestock farmer, and the livestock farmer dries the livestock manure. Spray acid.

An odor reduction company will supplement the burden of fruit growers and livestock farmers to supplement the economic operation of the region.

When this method of deodorizing livestock manure with organic acids from industrial waste is put into operation, in intermediate cities where agriculture, livestock, and industrial / commercial workers exist, the garbage generated in each household will be removed. Compost that decomposes in livestock compost and is more fertilizer efficient than livestock compost can be operated with less odor and less processing costs.
This not only incinerates and greatly reduces the cost of garbage disposal, but also eliminates the need for a large incinerator for treating garbage by incineration.
Not only that, “livestock compost + garbage compost” will be used happily by each farmer and citizen gardener, and further eco-cycle will be promoted.
