Abstract

Organic wastes from daily life, livestock industry or other industries are fed to earthworm and digested. The excretion of earthworm has a highly deodorizing effect as deordrant. The waste excretion after used as deodrant successively can be used as organic fertilizer since it contains much of ammonia gas, hydrogen sulfide gas or protein-decomposed gas, which is very useful for plant growth.

The present invention relates to the use of the earthworm fecal soil as a deodorant.

In particular, the present invention relates to household organic wastes, animal husbandry organic wastes and industrial organic wastes, for example, nutrients, livestock, pig meals, poultry and other livestock or poultry manure and pharmaceutical or food industry wastes, fermentation wastes and other industrial organic wastes It relates to the use of earthworm fecal soil obtained by ingesting and digesting wastes of other or other vegetables or other large cities or industrial organic wastes by earthworms as a deodorant.

Earthworms belong to the ring-shaped animal Binmo River, which are widely distributed in the soil, swamps, lakes, groundwater, caves, and coasts, and are known to have about 2,700 species worldwide.

These earthworms are known to have slightly different life styles and patterns depending on the region and type of habitat.

Earthworms eat about 0.9-1.2 times their body weight per day, and the amount of excreted soil excreted after ingestion is known to be about 0.3-0.8 times the amount of organic matter consumed.

Earthworms are generally elongated cylindrical, with an anterior mouth, an anus open at the rear end, and a large number of joints of almost the same shape. It leads to the chapter.

Most of the digestive tract is occupied by the intestines.

The earthworm is a female and female body (雌雄同體), one female body and one male reproductive organ, and reproduction requires two individuals.

It lays 3-8 eggs at a time of spawning and larvae emerge from 2-8 at 1 egg and mature fully at 3-4 months of age.

Earthworms are 1 year old and 5-10 year old.

Earthworms are excreted in the anus by swallowing the surrounding soil or organic matter and continuously excrete feces one by one as they eat.

The food that passes through the earthworm's intestine becomes the earth's neutral and the nitric acid is remarkably increased by the action of the earthworm's unique lime line.

Earthworms with these characteristics are currently used for fishing lures (increasing demand from both domestic and foreign countries), fish and algae for high-quality food and medicinal use, and earthworm feces are used as high-quality organic fertilizers. have.

That is, until now, the earthworm itself has been collected and used directly, or it has been used to breed the earthworm directly, or the fecal soil of the earthworm has been used as an organic fertilizer.

Due to the increase of population, the advancement of industry, and the improvement of life, the amount of organic wastes is increasing exponentially, which is a big problem in its treatment.

There are 149 manure treatment plants nationwide, with a treatment capacity of 12,677 kl / day (as of 1988), and sewage treatment plants are discharged from 17 places at 5.9 million tons / day and 9,000 industrial sites after waste, sewage and manure treatment. In general, it takes about 30-40% of the cost of the facility to properly dispose of it, and the transportation cost is known to be equivalent.

On the other hand, the treatment of various organic wastes, waste, sewage and manure treatment due to the inevitable expansion of sewage treatment public facilities, the increase of septic tank sludge due to the increase of flush toilets, and the increase of industrial facilities, etc., has increased dramatically. The use of existing treatment methods will increase the cost of excessive facility installation, treatment and operation costs, and landfill disasters, especially due to conflicts of interest between local governments under local governments. It will be very difficult to select landfills.

In particular, livestock manure and industrial organic waste, which are inevitably generated in serving, ranch or livestock industry, are currently undergoing primary treatment, simple landfill or incineration.

In the case of simple landfilling, not only a large landfill site is required but also various problems such as secondary pollution by leachate after landfilling, generation of toxic gas or odor, pests such as flies, and the like.

For example, the manure currently generated in Seoul alone produces 3000 tons per day, which is 2000 tons in Anyang Sewage Treatment Plant and 1000 tons in Nanjido.

Even if only the production of the Oni cake produced by the basic treatment, the amount of oni cake produced in Anyang Sewage Treatment Plant is 70 tons per day and the generation amount in Nanjido reaches 35 tons.

The basic process goes through the following process.

The oni cake produced in this way has been treated by adding chemicals such as calcium oxide or calcium hydroxide to the mixture, molding and transporting it to Nanjido.

This treatment requires a large landfill site, as well as secondary pollution by leachate after landfill, the cost of treatment or enormous.

In the case of livestock manure, the treatment is a big problem, it is a well-known fact that there are the same problems as in the treatment of serving and also problems such as contamination of water supply.

The same is true for industrial organic waste.

As a result of a long study on earthworms, the present inventors have found that ingestion and digestion of earthworms for human serving, livestock or poultry manure, or wastes of organic industrial waste, agricultural products, or forest products, wastes are processed in large quantities without pollution. In addition to the detoxification and at the same time a large amount of earthworms can be obtained and also the amazing fact that the fecal soil of earthworms used as a high-grade organic fertilizer was found to complete the invention and filed with the same patent. When the organic waste is treated by the method of the present invention described above, no chemicals are used, no pollution occurs, no landfill after treatment is required, and the treated feces can be used as a high-quality organic fertilizer, which is extremely useful. Invention.

The present inventors have been doing a long research on the treatment of organic waste using earthworms and have been experimentally treating phosphorus sludge since 1988 experimentally receiving 5-10 tonnes of servings of onyx from Anyang sewage treatment plant. To complete the experiment of the present invention by treating 30 tons of phosphorus per day.

The amount of processed sludge processed per tonne per day is equivalent to one third of Seoul's daily oncake production.

In addition, there is a problem that air pollution is severe and pests such as flies are caused by various harmful odorous substances generated by decomposition of ammonia, hydrogen sulfide or protein generated from phosphorus or phosphorus sludge. Treatment of sludge by the method of the invention not only produces no odor at all in the treatment plant, but also no pests.

It is known that the lugworm has a component called meraytoxin, which paralyzes the nerves of insects in its body, and similar components are present in the earthworm and the earthworm feces.

In the method of the present invention, it is only necessary to cover the oni cake of organic waste on the earthworm and maintain the temperature at about 10-35 degrees.

Preferred temperatures are about 15-30 degrees.

The water content of the onicake is about 30-90% by weight, preferably about 50-75% by weight. When the onicake contains too much water, pretreatment, for example, dehydration, is used to suit the conditions.

In this way, earthworms eat and grow sludge more than their own weight a day, and produce fecal soil about 1/3 to 1/2 of sludge.

The fecal soil thus produced is used as a very good organic fertilizer.

Parasite eggs, which may be present in the feces ingested and excreted by the earthworm, are denatured and inactivated during the passage of the earthworm's gastrointestinal tract and become incapable of hatching. There is no concern.

The feces, which the earthworm eats, digests, and discharges, are composed of fine particles, which contain a large amount of fertilizers and contain many microorganisms and enzymes in addition to physical phenomena which increase the air permeability and water absorption of soil. Its effect is great. As a result of a long study on the use area of the earthworm fecal soil, the present inventors have found that the earthworm fecal soil has a great deodorizing effect and can be used as a useful deodorant to complete the present invention.

Therefore, an object of the present invention is to provide a use of the earthworm fecal soil as a deodorant.

Waste fecal soil after use as a deodorant in the present invention is a bad odor gas generated by decomposition of ammonia or hydrogen emulsion or protein containing a large amount of ammonia and hydrogen emulsified by adsorbing or combined by other physicochemical methods It is a useful fertilizer for plants, so the waste feces after use as a deodorant can be used as a more useful organic fertilizer.

Ammonia gas and hydrogen sulfide gas are harmful to animals but are very useful fertilizers for plants.

For example, ammonium sulfate, ammonium nitrate, ammonium carbonate, or urea, which are used as useful nitrogen fertilizers, are all salts of ammonia with acids or compounds in which ammonia is bound.

However, chemical fertilizers such as nitrogen fertilizers are limited in their use due to acidification and deterioration of soil by long-term use. Therefore, the waste fecal soil of earthworms rich in ammonia is very much absorbed or combined by other methods. It can be used as a good organic fertilizer.

Hydrogen emulsified gas can also be used as a nutrient source for trace elements that are harmful to animals but useful for plants.

Next, the present invention will be described in more detail as Examples and Experimental Examples.

Example 1:

Spread one ton of earthworms evenly into a 1-square-meter plastic house, and cover and spread it evenly with 1 ton of onic cake with a water content of about 50 (weight).

The temperature is adjusted to about 30 degrees and maintained for 24 hours.

After 24 hours, the earthworm ingests and digests all of the serving onicake to produce about 0.3 tons of fecal soil.

In this case, no pest such as flies is generated, and the resulting fecal soil becomes an excellent organic fertilizer.

The separation of feces and earthworms after treatment is easy because the earthworms move to the waste when the organic waste is covered on the earthworms and the feces.

Example 2

Spread one ton of earthworms evenly in a 1-square-meter plastic house, and then spread and cover a ton of onyx cakes with approximately 50% moisture by weight.

The temperature is adjusted to about 25 degrees and maintained for about 30 hours.

In this process, the nutrient powder oniche is ingested and digested by the earthworm, producing about 0.3 tons of fecal soil, and the resulting fecal soil becomes an excellent organic fertilizer.

Even in this case, pests such as flies do not occur at all.

Example 3:

Spread 1 ton of earthworms evenly in a 1-square-meter plastic house, and cover and spread it evenly with 1 ton of onicake with 50% moisture content.

The temperature is maintained at about 30 degrees for about 24 hours.

When this process is done, the earthworms are digested and eaten by earthworms, and produce about 0.3 tons of fecal soil.

In this case, no pest such as flies occurs.

Example 4

Spread one ton of earthworms evenly in a 1-square-meter plastic house, and evenly cover one ton of fermentation waste from a pharmaceutical company with a moisture content of about 65% (weight).

Maintain the temperature about 30 degrees and keep it for 24 hours.

In this way, the fermentation waste is ingested and digested by the earthworm, and produces about 0.2 tons of fecal soil.

These feces become high grade organic fertilizers,

There are no pests in the process and feces.

Example 5

Spread one ton of earthworms evenly in a 1-square-meter plastic house, and cover an even ton of tons of 45% (weight) moisture.

Maintain the temperature about 30 degrees and keep it for 24 hours.

In this way, all the meal is digested by the earthworm, producing about 0.5 tons of fecal soil.

This fecal soil is used as a high quality organic fertilizer.

During the treatment and in the feces, no pests such as flies or mosquitoes are seen.

Example 6:

Spread one ton of earthworms evenly in a 1-square-meter plastic house, and evenly cover one ton of amino acid fermentation waste of about 60% (weight) of water.

The temperature is maintained at about 30 degrees for 24 hours.

This treatment produces about 0.3 tonnes of fecal soil when the earthworms ingest and digest all of the fermentation waste.

This fecal soil becomes a high quality organic fertilizer.

Pests do not occur at all.

All temperatures used in the present invention are degrees Celsius.

All fecal soil obtained by ingesting and digesting all industrial wastes and organic wastes into earthworms can be used in the method of the present invention.

Experimental Example 1:

Deodorizing effect of earthworm feces:

In the experiment on the deodorizing effect of earthworm fecal soil as a deodorant, the exhaust gas discharged by blowing the odor in the method of FIG. 2 using the experimental apparatus as in FIG. The amount of gas absorbed through the absorption tube through the flow meter was measured. The experimental results thus measured are shown in Table 1 below.

TABLE 1

In the table above, odor strengths 1 and 1.5 are odor strengths of which the human body almost does not feel the odor.

According to the test results, the earthworm fecal soil has a very good deodorizing ability, and thus can be used as a useful deodorant, and the waste fecal soil after deodorization can be used as an excellent organic fertilizer.
