持っている。Chicken manure cannot be used as fertilizer in its raw state. This is because the nitrogen sulfate compounds contained in chicken manure damage crop roots. Fermentation can remove sulfate nitrogen compounds contained in chicken manure. Fermented chicken manure becomes a high-quality organic fertilizer. However, there is a drawback that the highly valuable nitrogen component becomes ammonia gas and is extremely reduced. Organic fertilizer made from chicken manure is ideal for golf courses and garden farms, as there is no risk of pesticide contamination. To use chicken manure as organic fertilizer, it is fermented and then dried until the moisture content is 20% or less. The moisture content of chicken manure is reduced from 75 to 80% to 50 to 60%, and fermentation occurs when the moisture content is 50 to 60%. In this process,
In chicken manure, unnecessary components except nitrogen, phosphoric acid, and potassium are changed (L) and removed. Fermentation of chicken manure takes about 60 days. A chicken house housing 100,000 chickens produces a huge amount of 20 tons per day. The huge amount of chicken manure that is generated every day takes a considerable number of days to process.The conventional method requires a large amount of chicken manure to be stored, and the processing capacity limits the number of chickens that can be raised. By the way, it takes 7000m2 to 100m2 to process 100,000 chicken manure.
A site of 00m2 is required. The following publication describes a method of adding quicklime powder to shorten the drying time of chicken manure. ■ JP-A No. 58-41787 ■ JP-A No. 50-3852 The methods described in these publications include adding quicklime to chicken manure, and heating and drying the chicken manure with the heat that causes the quicklime to react with water. I'm letting you do it. Quicklime has the property of reacting with water to become slaked lime and generate heat. According to this method, for example, 10% by weight
The moisture content of chicken manure can be reduced by 10% by adding quicklime. Quicklime has properties as an excellent organic fertilizer.

るにある。The method of adding quicklime has the advantage of drying chicken manure in a short time. However, when quicklime is added to chicken manure,
It has the disadvantage of severe nitrogen loss. It has traditionally been said that quicklime is not desirable to add to nitrogen-based fertilizers. The reason for this is that the loss of 6 nitrogen is enormous. When quicklime is added to chicken manure, nitrogen is lost in the form of ammonia gas. For this reason, chicken manure with added quicklime spreads the toxic odor of ammonia into the surrounding area. In other words, it causes foul odor pollution and also has the disadvantage of causing loss of important nitrogen components contained in fertilizer. This invention was developed with the aim of further solving this drawback, and the important purpose of this invention is to add phosphoric acid in addition to quicklime to chicken manure to fix quicklime, phosphoric acid, and mononitrogen. In addition, it is an object of the present invention to provide a method for producing a fertilizer that eliminates odor pollution and can produce a high value-added organic compound fertilizer.

に対し、０．１〜２．５ｇ。
好ましくは０． ８〜１．５ｇの範囲に調整される。In the method for producing fertilizer using chicken manure of the present invention, quicklime is added to chicken manure in order to achieve the above-mentioned object. The amount of quicklime added is usually adjusted to 5 to 25 g, preferably 10 to 20 g, per 1.00 g of undried chicken manure. By increasing the amount of quicklime added, the moisture content of chicken manure can be lowered. However, if the amount added is too large, the amount of heat generated will be too large and the temperature will become high, and the cost of raw materials will also increase. - Chicken manure to which quicklime has been added generates a large amount of ammonia gas through hydration and fermentation. In order to fix nitrogen contained in ammonia gas, this invention further adds phosphoric acid. Phosphoric acid reacts with ammonia gas to produce ammonium phosphorus. Since phosphoric acid reacts with generated ammonia gas, the amount added is adjusted to the amount that eliminates the bad odor of ammonia gas. The amount of phosphoric acid added is 100g of chicken manure.

Kcal From this equation, when 1 mole (56 g) of calcium oxide reacts with water to form calcium hydroxide, 15.
Generates 165 calories of heat. That is, when 1 kg of quicklime reacts with water, it generates approximately 240 calories of heat. The water that reacts with quicklime is the water contained in chicken manure. Usually, the moisture content of chicken bones before drying is about 75%. Chicken manure to which quicklime has been added undergoes hydration and fermentation to produce ammonia gas. Ammonia gas is a compound of nitrogen and hydrogen, so when it disappears, the nitrogen contained in chicken manure is lost. Therefore, in this invention, phosphoric acid is further added and reacted with ammonia gas. By reacting ammonia gas with phosphoric acid, loss of nitrogen components from chicken manure is inhibited. By reacting phosphoric acid with ammonia, nitrogen is fixed and ammonium phosphorus, an active ingredient in fertilizers, is produced. When the chicken manure treated in this state is further dried, it becomes an organic chemical fertilizer with extremely high added value.

However, the examples shown below are illustrative of a method for embodying the technical idea of the present invention, and the method of the present invention is not limited to the following conditions. Various modifications may be made to the method of this invention within the scope of the claims. [Example 1] Chicken manure is processed into organic chemical fertilizer in the following steps. ■ Weigh 10 kg of chicken manure with a moisture content of 75%. ■ For chicken manure, 1. Add 5Kg of quicklime powder and mix. (2) Furthermore, 50 cc of 85% phosphoric acid is diluted in 450 cc of water, and the diluted phosphoric acid solution is added to the chicken manure that is being stirred to uniformly disperse the phosphoric acid. ■ In this state, the chicken manure is heated to about 80'C or higher and fermented at high temperature. At this time, ammonia gas generated from chicken manure reacts with phosphoric acid to become ammonium phosphorus. After several days in this state, the chicken manure is fermented to remove nitrogen sulfate compounds and dehydrated to a moisture content of 60%. ■ Furthermore, this chicken manure is transported to a dryer and the moisture content is reduced to 2.
It is dried until it becomes 0% and used as an organic compound fertilizer. The fertilizer obtained in this process was not granulated and became a coarse sand powder that was loose and easy to handle. Furthermore, no bad odor is generated during the processing of chicken manure, and the loss of nitrogen components contained in chicken manure can be prevented. The content of nitrogen, phosphoric acid, and potassium in the organic fertilizer produced in this process is as follows: 1゜■ Nitrogen: 4.1%■ Phosphoric acid--- 4.6% ■ Force 1 l...1.2% [Comparative example 1
] No addition of phosphoric acid A1 In the same manner as in Example 1, an organic fertilizer using chicken manure was produced as a prototype. The nitrogen, phosphoric acid, and potassium contents of the obtained organic fertilizer were as follows. ■ Nitrogen・・・・・・・・・1. 0%■ Phosphoric acid・・・・・・1.5%■ Potassium・・・・・・・・・
...0. 5% [Example 2] The amount of quicklime added was 1. Chicken manure is used as an organic compound fertilizer in the same manner as in Example 1, except that the amount of phosphoric acid is changed from 5 kg to I kg, and the amount of phosphoric acid added is changed from 50 cc to 100 cc. The fertilizer obtained in this process was also easy to handle in the form of crumbs. In addition, no bad odor was generated during the processing of chicken manure, and the loss of nitrogen components contained in chicken manure could be prevented.

酸の含有率も多くできる特長がある。The method for producing fertilizer using chicken manure of the present invention is an extremely simple method, and realizes the feature that chicken manure, which is difficult to dispose of, can be effectively used as an extremely high value-added organic chemical fertilizer. This feature is achieved by the method of the invention by adding phosphoric acid in addition to quicklime. The quicklime added to chicken manure is quickly fermented and dried through hydration and fermentation to generate heat. Furthermore, the nitrogen component, which was lost in the fermentation process in conventional methods, is fixed by reacting with phosphoric acid, making it effective as a fertilizer. Phosphorous ammonium is generated. By processing chicken manure in this state, the method of the present invention, which can produce high value-added organic chemical fertilizer, reduces and simplifies the cost of processing chicken manure, and does not discard chicken manure. As a result, it can be made into a product with high added value as an organic fertilizer, and its economic effects are significant. Using this method, it is possible to eliminate the restriction on the number of chickens raised due to chicken manure treatment. Furthermore, the method of the present invention not only can significantly shorten the processing period for chicken manure, but also has the advantage of eliminating bad odor pollution during the processing process. Table 1 shows the test results of malodor reduction by using the method of this invention. (Left below) Table 1 ■ 20g phosphoric acid + 180cc water, ■ Tap water 20

It shows the results of measuring ammonia gas generated by adding water in c. As shown in this table, when 20 g (0.5%) of phosphoric acid is added, the ammonia gas becomes 900 p p before addition.
m, has been drastically reduced to 12 ppm. Ammonia gas at 900 ppm has a so strong odor that it is difficult to breathe, but when the concentration is reduced to 12 ppm, it becomes almost odorless. =11- When water or a conventional deodorizing agent was added, the ammonia gas amounted to 200 to 900 ppm, and a strong odor was generated. Furthermore, as is clear from comparing Example 1 and Comparative Example 1, the organic fertilizer produced in Example 1 according to the present invention had a nitrogen component content of 41%, whereas the comparative example As shown in No. 1, the nitrogen content of the fertilizer produced by adding only quicklime to chicken manure without adding phosphoric acid was 1.0%. In other words, the organic fertilizer produced by the method of this invention contains about four times as much nitrogen as the organic fertilizer produced by the conventional method. It has the advantage of increasing the phosphoric acid content.
