Manufacturing method of soil improving material

The present invention relates to a soil improving material and a manufacturing method by causing additives containing calcium oxide as a main component to livestock manure, excess water and sewage, and other perishable industrial wastes (scrap, sawdust, animal blood, etc.).

The conventional soil improving materials include chemicals such as potassium lactate and ammonium phosphate urea, fermentable soil improving materials using composting reactions, and soil improving materials using microbial cells.

The use of chemicals is excellent in fast-acting effects, but has the drawback of lowering intellect due to the destruction of the growth environment of effective microorganisms. In addition, by spraying slaked lime to the soil to neutralize acidic soils to prevent acid fermentation to prevent the occurrence of pests, however, calcium salt concentration disturbance occurs.

In the case of using the composting reaction, the reaction takes a long time, and nitrogen is absorbed by the microorganisms, indicating a phenomenon of nitrogen famine. In addition, in the case of soil improvement materials using microorganisms, it is difficult to adapt to changes in the environment, and in particular, has a problem of low resistance to chemicals.

In view of the problems of various conventional soil improving materials, the present invention creates an environment that takes less time to manufacture and activates the action of effective microorganisms than composting, and easily and reliably absorbs inactive ingredients. It is an object of the present invention to provide a soil improving material and a method for producing the same, which are capable of sustaining ineffectiveness and increasing intellect.

Since the soil improving material according to the present invention achieves the above-mentioned object, most of the phosphoric acid contained in the perishable waste is stable as the effective calcium phosphate as the soil improving material from the reaction product of the solid-liquid mixed perishable waste and calcium oxide. In addition, it is reduced to less than 3% of the initial amount of water-soluble phosphoric acid, and the decomposition of hardly decomposable components such as organophosphoric acid, phospholipid glyceride, and liguin is produced.

It is characterized in that it contains dispersed organisms of calcium phosphate, fatty acid calcium or calcium, and the production method according to the present invention has a calcium oxide content of 95% or more and a porosity with respect to 100 parts by weight of perishable oxidation + waste in solid-liquid mixing. 5-50 parts by weight of an additive having a high active quicklime as a main component was added and mixed and stirred to react to obtain an electrical soil improving material by drying the obtained slari phase material. will be.

As perishable wastes used as raw materials of the present invention, there are perishable wastes discharged from food manufacturing plants such as pig manure, poultry, other livestock manure, animal blood wastewater and sewage, perishable industrial wastes such as surplus sludge, bean waste or soybean waste. .

These are usually 86.5% -94.5% for pig manure, for example 15-30% water and sewage for dry meal, 75-97% for surplus sludge and 75-95 for decay residue in food factories. It is preferable to adjust the moisture in the state of 75-97% in using% as moisture, and using it as a raw material of this invention.

The soil improvement material which concerns on this invention is obtained by adding, mixing, and stirring an additive to such raw materials.

Specifically, it is prepared by adding 5-50 parts by weight of a predetermined additive to 100 parts by weight of the perishable industrial waste. The additive contains, as a main component, highly active quicklime having the following conditions.

(1) The content of calcium oxide is high (95% or more is preferred) and the content of calcium hydroxide, calcium carbonate and other substances is low. As the composition component, a small amount of magnesium oxide (eg, 5% or less) may be contained.

(2) The surface area and specific surface area with porosity are large and the pore structure is highly developed.

(3) A small amount of water, for example water, should have good water dissipation when contacted with 1-2g in about 10-15mg, that is, it will disperse widely in all directions.

(4) Weight of water For example, when water is added to 5-10g at about 15-20mg, it reacts hard within a few seconds to generate water vapor.

(5) When a certain amount of water, for example, 20 g is added to 100 mg of water, it should be sufficiently reacted and a temperature rise close to the theoretical value should be recognized.

(6) After contact with water, the sintering rate of slaked lime is the slowest sedimentation rate, e.g., no sedimentation phenomenon occurs in the state left undisturbed for 15 minutes with the proportion as described in (5) above.

Among the conditions (1)-(6), (3)-(5) is a property that can be inevitably received from (1) and (2), and (6) is a condition of (1)-(5). This is the condition when the final check is made to see if it is being met.

When the reaction time by the additive which has such a high-active quicklime as a main component is too long, micronization occurs, and the resulting soil improving material is less likely to become a monolithic structure and difficult to dry.

However, when the raw materials contain substances that are difficult to react, such as, for example, phospholipid liquid oil basic substances, hardly decomposable polymer compounds, the reaction time is appropriately extended.

In addition, when the additive is added to the perishable waste in proportion as described above, the additive may be added at several times instead of at once.

The perishable waste is generally composed of extremely many kinds of components, and also has various reaction characteristics with the above-mentioned additives having high activity.

Ingredients that tend to form poorly soluble salts of inorganic acids and calcium react relatively easily, but fats, phospholipids, oils, high molecular weight proteins, hemicellulose, and ligunin are relatively difficult to react. In the case where the number of times of addition of the additive is one, the component that is easy to react is preferentially reacted.

Therefore, when the additive is first in contact with a relatively large amount of moisture and in contact with the above-mentioned components that are difficult to react, the additives are not sufficiently utilized, and are reacted in the form of calcium hydroxide. If the number of times of addition of additives is more than two times, that is, the first reaction is preferentially reacted with the component that is easy to react, and after the first addition, the proportion of components that are difficult to react relatively (before the second addition) is large. The high activity of the furnace additives is more effectively utilized. That is, the reaction rate improves as the reaction proceeds to various components that are difficult to react.

In addition, the temperature of the reactant slurry itself by the first additive increases, the reaction rate is increased, the viscosity decreases, and the contact state with the component that is difficult to react is also improved.

The number of times of addition may be divided into two or more, three or more times, but in many cases a significant effect is achieved as two or three times. In each case, the amount of the additive added may be uniformly divided, i.e., twice or 1/2 times, or three times, or three times, but the amount may be changed depending on the state of the perishable waste to be treated.

When there are a lot of components that are relatively easy to react, the amount added first is greater than that after the second time. On the contrary, when there are few components that are relatively easy to react, the amount added after the second time is increased to increase the amount after the second time. Desirable.

In this way, by applying the addition method several times, the reaction proceeds, the state and quality of the reaction product are more stabilized, and the total amount of the additive can be reduced.

In addition, when the additive is contained 5% or less of magnesia, it can be obtained even more effective as a soil improving material to be described later.

Soil activator obtained as a reaction product is calcium phosphate and fatty acid calcium, in which about 97% of the water-soluble phosphoric acid contained in the organic waste is fixed as calcium phosphate in an active form, and decomposes hardly decomposable components such as organic phosphate, phospholipid and glyceride It contains an organism in which calcium is dispersed in the back. Effective calcium phosphate is produced by the reaction of the additive with the phosphoric acid contained mainly in water-soluble phosphorus and phospholipids present in perishable waste.

Therefore, the soil improver significantly reduces the water-soluble phosphoric acid and lipids contained in the perishable waste as a raw material. In the case of a perishable waste containing a relatively large amount of glycerides, glycerides form stable poorly soluble calcium salts by a hydrolysis reaction with a base due to a strong calcium oxide.

As a result, anaerobic fermentation caused by unreacted residues and generation of gas or pests are not generated in the soil improving material. As a result of the rapid expansion of calcium oxide in the additive to the perishable waste, this soil improving material is formed as a substance having a large porosity or a large space rate by expanding and drying the volume once.

As described above, this soil improving material contains inorganic calcium phosphate produced by the decomposition of hardly decomposable components such as organic phosphoric acid, and dispersed organisms of fatty acid calcium and inorganic compounds of organic compounds having inorganic and organic double-sided properties. As a whole, it is comprised as the complex which the organic mineral couple | bonded, and when it is reduced, the complex in which the organic mineral was suitably mix | blended.

For this reason, this soil modifier has adequate slowness or sustainability and sustainability. In other words, in the present invention, since calcium ions (Ca ²⁺ ) and hydroxyl groups (OH ⁻ ) have a high activity, the calcium oxide as an additive at the time of reaction generation has high activity, so that calcium is physically uniform in all directions (three-dimensional directions). Are distributed.

In addition, as a result of the production using such additives, the temperature rises and the viscosity decreases at the time of formation, while cellulose liguinine, high molecular weight protein, phospholipids, etc. branch off due to alkalinity and are locally heated by the reaction of calcium oxide with water. By this, the raw material is decomposed into low molecular weight compounds.

Thus, calcium is bound to the degraded terminal to form a relatively poorly soluble calcium salt.

On the other hand, calcium in glass forms and disperse | distributes the various compound and gired compound which were decomposed.

In other words, relatively poorly soluble calcium salts are rapidly formed with carboxyl groups that have undergone significant degradation. Free phosphate groups produce rapidly stable calcium phosphate.

Phosphate groups in the phospholipid are partially freed together to form calcium phosphate. In a high molecular compound having an electron-absorbing group including an oxygen atom, calcium ions are strongly acted by thermal and mechanical diffusion, decompose and invade as a salt of calcium. In addition, it reacts immediately with the group (base) which is easily reacted with calcium.

Calcium present in excess is dispersed as a giredo compound.

In addition, the calcium compound formed acts by immobilizing proteins with amino and carboxyl groups.

As a result of the above phenomenon, a complex organic material in which calcium salt is dispersed is formed in a raw material composed of various various components. Examples of the present invention are illustrated below.

Example 1

Addition of 120 kg (15% by weight of the raw material) with the main ingredient of quicklime with high activity to 800 kg of slurry of 88.5% by weight of water containing manure as the main raw material was reacted for 10 minutes while stirring in a special reactor.

In the reaction process, the temperature of the reactant slurry was increased by the reaction heat generated by the hydration reaction and the chemical reaction between quicklime and water, and the temperature rise (difference between the reactant slurry temperature and the raw material slurry temperature) was 32.5 ° C.

The reactant slaley obtained was brought into contact with the atmosphere in a roofed house (attached to a forced ventilation facility) and dried to obtain 395 kg of a reaction product having a water content of 3.5% by weight.

The ammonia nitrogen content in the raw material was 28.600 mg / kg (dry basis), while the component in the reaction product was 150 mg / kg (dry basis).

The water-soluble phosphoric acid content in the raw material was 27.700 mg / kg (dry basis), while the component in the reaction product was 121 mg / kg (dry basis).

As for the removal rate (reduction rate) of ammonia nitrogen by this Example, the removal rate (reduction rate) of 99.5% water-soluble phosphoric acid is 99.6%, and these remarkable effects are recognized.

Example 2

As a raw material, 100 kg (12.5% by weight of raw material) of additives, which are composed mainly of quicklime with high activity, are added to 800 kg of water 87.5% slaley, which is a mixture of pig manure and surplus sludge, and stirred in a special reactor. The reaction was carried out for 10 minutes.

In the above reaction, the temperature of reactant slarry is increased and the temperature rise (difference between reactant slurry temperature and raw material slurry temperature) is 33.5 ℃ due to the heat of reaction generated by hydration and chemical reaction between quicklime and water. Had been.

The reactant slaley thus obtained was brought into contact with the atmosphere in a roofed house (with a forced ventilation system) and dried to obtain 375 kg of a reaction product having a water content of 38.0% by weight.

The water-soluble phosphate content in the raw material was 4.911 mg / kg (dry basis), while the component in the reaction product was less than 10 mg / kg (dry basis).

In addition, the ammonia nitrogen content in the raw material was 34.700 mg / kg (dry basis), whereas the component in the reaction product was 202 mg / kg (dry basis).

The removal rate (reduction rate) of water-soluble phosphoric acid according to the present Example (reduction rate) of 99.0% or more corresponds to 99.4%.

Also in the present Example, the present reduction effect with respect to water-soluble phosphate ammonia nitrogen like Example 1 is recognized.

Example 3

Next, the Example when the addition amount of the additive with respect to a raw material is small is shown. As a raw material, 32 kg (3.9% by weight of the raw material) of the additive was added to 820 kg of the slurry of 86.9% by weight, which is a mixed ingredient of pork and surplus sludge, and reacted for 8 minutes while stirring in a special reactor. In the reaction, the temperature rise was 15.0 ° C. The obtained reactant slurry was dried to obtain 270 kg of a reaction product having a water content of 40.5% by weight. The water-soluble phosphoric acid content in the raw material was 12.200 mg / kg (dry basis). The component in the reaction product was 405 mg / kg (dry basis). The ammonia nitrogen content in the raw material was 34.200 mg / kg (dry basis). This component in the reaction product was 8.550 mg / kg (dry basis). In this embodiment, the amount of the additive is insufficient, and therefore, the removal rate (reduction rate) of 96.7% of ammonia nitrogen was only 97.5%. According to this embodiment, the removal rate of the water-soluble phosphoric acid is too low to contain a large amount of phosphoric acid which is relatively easy to react in the product, and as a result, components that are difficult to react remain in the product in an unreacted state, so that a sufficiently effective soil improving material cannot be obtained.

Example 4

The example in the case where the addition amount of the additive with respect to the following raw material is excessive is illustrated. The additive was added to 820 kg of Sliri 820 kg of water, 86.9 wt% of water from the mixed components of manure and surplus sludge as a raw material, and stirred for 8 minutes while stirring in a special reactor. The temperature rise in said reaction was 67 degreeC. The resulting reactant slurry is extremely viscous and a marked drop in fluidity is recognized. The water-soluble phosphate content was 12.200 mg / kg (dry basis). In addition, the ammonia nitrogen content in the raw material was 34.200 mg / kg (dry basis), and the component of the reaction product was 107 mg / kg (dry basis). The removal rate (reduction rate) of the water-soluble phosphoric acid according to the present example was 99.9%, and the removal rate (reduction rate) of the ammonia nitrogen was 99.7% and high removal rate, but the difference is relatively small. It is understood that the addition rate of the additive is desirable because the fluidity of the reaction product, in particular, the fluidity is considerably lowered and the calcium content in the reaction product may be excessive.

Example 5

The additive was added to 140 kg (16.5 wt.% Of the raw material) with respect to 85.0 wt.% Of Sliri 850 kg of water containing a mixture of flour, sawdust, and pig manure as a raw material, and reacted for 15 minutes while stirring in a special reactor. In the reaction process, the temperature of reactant slurry is increased and the temperature rise (difference between reactant slurry temperature and raw material slurry temperature) is 46 ° C due to the heat of reaction generated by hydration and chemical reaction between quicklime and water. It was. The reactant slaley obtained was contacted with the atmosphere in a roofed house (with a forced ventilation system) and ventilated to obtain 505 kg of a reaction product having a water content of 38.0% by weight. The water-soluble phosphoric acid content in the raw material was 11.200 mg / kg (dry basis), and the component in the reaction product was 59 mg / kg (dry basis). In addition, the lipid content of the raw material was 39.200 mg / kg (dry basis), and the corresponding component in the reaction product was 5.220 mg / kg (dry basis). The phosphoric acid removal rate (reduction rate) according to the present example is 99.5%, and the lipid removal rate (reduction rate) corresponds to 86.7%. As is clear from the present example, when a mixed ingredient such as flour was used as the raw material, a significant reduction effect on the water-soluble phosphate lipid was recognized.

Example 6

9 kg of the above-mentioned additive which is mainly composed of quicklime with high activity against 45 kg of 80% by weight of water slurry, adjusted by adding 15 liters of aquatic animals to 30 kg of industrial wastes containing the residue after soybean protein extraction. 20.0% by weight of the raw materials) was added, stirred in a special reactor, and reacted for 30 minutes. In the reaction process, the temperature of the reaction slurry rises due to the hydration reaction between quicklime and water and the reaction heat generated by the chemical reaction. ° C. The obtained reaction slurry was contacted with air to dry air to obtain 28 kg of a reaction product having a water content of 25% by weight. The water-soluble phosphoric acid content in the raw material was less than 60 mg / kg (dry basis) of the component in the reaction product at 2,740 mg / kg (dry basis). In addition, the lipid content in the raw material was 72.700 mg / kg (dry basis), and the component in the reaction product was 5.350 / mg 1 kg (dry basis). The removal rate (reduction rate) of the water-soluble phosphoric acid according to the present example is 97.5% or more, and the removal rate (reduction rate) of the lipid is 92.6%. As is apparent from this example, a significant reduction effect on lipids of water-soluble phosphoric acid is recognized even for unusual organic industrial wastes.

Example 7

45 kg of industrial waste containing fish starch and the like as a main raw material, 45 kg of industrial waste containing 15 liters of water, adjusted to 60 kg of slurry of 75% by weight of water and 15 kg of additives as in the above example (raw material) 25 wt%) was added and the mixture was stirred with a special reactor for 30 minutes. In the reaction process, the temperature of the reactant slurry is increased by the reaction heat generated by the hydration reaction and the chemical reaction between quicklime and water, and the temperature rise (the difference between the reactant slurry temperature and the raw material slurry temperature) is 50 degreeC. The resulting reactant slaley was contacted with air to dry air to obtain 44 kg of a reaction product having a water content of 25.0%. The content of water-soluble phosphoric acid in the raw material was 37 mg dry weight of the component in the reaction product of 4.090 mg / kg (dry basis). In addition, the total nitrogen content in the raw material was 60.700 mg / kg (dry basis), and the corresponding component in the reaction product was 11.500 mg / kg (dry basis). The removal rate (reduction rate) of the water-soluble phosphoric acid according to the present example corresponds to 99.1% of the removal rate (reduction rate) of all nitrogen. In addition to the reduction of total nitrogen, it is also conceivable that the protein undergoes hydrolysis under strong alkaline and is removed as a hydrophobic component in addition to the reduction of ammonia nitrogen. Also in this Example, the remarkable reduction effect with respect to the water-soluble nitrogen before phosphoric acid is recognized.

Example 8

9.5 kg (24.3% by weight of raw material) was added to 39 kg of water, 82% by weight slurry, adjusted by adding 17.5 L of tap water to 21.5 kg of surplus sludge discharged from the water treatment facility of the cacao oil-sugar confectionery factory. The reaction was carried out for 36 minutes with stirring in a special reactor. In the reaction process, the temperature of the reactant slurry is increased by the heat of reaction generated by the hydration reaction and the chemical reaction between quicklime and water, and the temperature rise is the difference between the reaction slurry temperature and the raw material slurry temperature. It was. The obtained reaction slurry was contacted with air to dry air to obtain 24.5 kg of a reaction product having a water content of 18.5% by weight. The water-soluble phosphoric acid content in the raw material was 18 mg / kg (dry basis) of the component in the reaction product of 147 mg / kg (dry basis). In addition, the lipid content in the raw material was 34.10 mg / kg (dry basis), and the component in the reaction product was 2.370 mg / kg (dry basis). The removal rate (reduction rate) of the water-soluble phosphoric acid according to the present example is 87.8% The removal rate (reduction rate) of the lipid corresponds to 93.0%. An example is shown when the following additive is distributed several times.

Example 9

After 1.5 minutes had elapsed since the first addition, the second time was added, and the reaction time was reacted for 8 minutes after the first time. In the above reaction, the temperature rise (difference between the reactant slurry temperature and the raw material slurry temperature) was 22.5 ° C. The resultant reactant slaley was contacted with the atmosphere in a roofed house and dried to give 270 kg of reaction product having a water content of 41.5% by weight. The water-soluble phosphoric acid content in the raw material was 16.400 mg / kg (dry basis), and the component in the reaction product was 40 mg / kg (dry basis). The ammonia nitrogen content in the raw material was 48.800 mg / kg (dry basis). The removal rate of the water-soluble phosphoric acid by this Example is 99.8%, and the removal rate (reduction rate) of ammonia nitrogen is 99.8%. According to this embodiment, the effect of reducing significantly is recognized for the water-soluble ammonia nitrogen and clearly shows the characteristics of the addition twice.

Example 10

Under the same conditions as in Example 9, 60 kg (7.0 wt% of the raw material) of the additive was added to the same amount of raw material, followed by stirring in a special reactor, and stirring for 8 minutes resulted in a temperature rise of 18.5 ° C in the reaction. The obtained reactant slurry was dried to obtain 275 kg of a reaction product having a water content of 42.0 wt%. The content of water-soluble phosphoric acid in the raw material was 16.400 mg / kg (dry basis), and the component in the reaction product was 103 mg / kg (dry basis). The ammonia nitrogen content in the raw materials was 322 mg / kg (dry basis) of the component in the reaction product at 48.800 mg / kg (dry basis). The removal rate (reduction rate) of the water-soluble phosphoric acid according to the present example corresponds to 99.3% removal rate (reduction rate) of 99.4% ammonia nitrogen. According to this Example, the corresponding reduction effect is recognized with respect to water-soluble phosphoric acid and ammonia nitrogen, but compared with the case where it adds twice, the removal rate (reduction rate) with respect to a positive component falls slightly.

Example 11

In the present Example, the example when the additive is added twice in the same quantity, respectively is shown. As a raw material, 70 kg (8.1% by weight of the raw material) was added as the first addition amount to 860 kg of Sliri, which contains 87.0% by weight of water, which is a mixed ingredient with chicken flour, sawdust and pig manure. A total of 140 kg (16.3 wt% of the raw material) was added and reacted with stirring in a special reactor. After 2 minutes had passed since the first addition, the second addition was carried out, and the reaction time was 15 minutes after the first addition. In the above reaction, the temperature rise (difference between the reactant slurry temperature and the raw material slurry temperature) was 45 ° C. The reactant slaley obtained was contacted with air in a roofed house and dried in air to obtain 495 kg of a reaction product having a water content of 40.0 wt%. The component in the reaction product was 63 mg / kg (dry basis) while the water-soluble phosphoric acid content in the raw material was 11.200 mg / kg (dry basis). In addition, the oil content in the raw material was 23.700 mg / kg (dry basis), while the component in the reaction product was 1.470 mg / kg (dry basis). The removal rate (reduction rate) of the water-soluble phosphoric acid according to the present example is 99.4%, and the removal rate (reduction rate) of the oil is 93.8%.

Example 12

16.8 weight of additives (140 kg) was added to 860 kg of Sliri 860 kg of water, which is the same ingredient as Example 11, mixed with a mixture of sawdust and pig manure, and stirred in a special reactor for 15 minutes. I was. The temperature rise by the above was 36.0 degreeC. The obtained reactant slurry was dried to obtain 495 kg of a reaction product having a water content of 40.0 wt%. The water-soluble phosphoric acid content in the raw material was 138 mg / kg (dry basis) of the component in the 11.200 mg / kg reaction product. Moreover, the oil content in the raw material was 23.700 mg / kg (dry basis), and the component in the reaction product was 2.100 mg / kg (dry basis). The removal rate (reduction rate) of the water-soluble phosphoric acid according to the present example is 98.8%, and the removal rate (reduction rate) of the oil content is 91.1%. According to the present Example, although it considers that it is a considerable reduction effect with respect to water soluble phosphate fraction, compared with the case of adding twice, the removal rate with respect to a positive component is falling.

Example 13

This example shows the case where the amount of each additive is different by adding twice. With respect to 87.0% by weight of water composed of mixed ingredients such as flour, sawdust and pig manure and 860 kg of Sliri as raw materials, 20 kg (2.3% by weight of raw materials) was added as the first addition amount and 120 kg (raw material) as the second addition amount. 140 kg (16.3 wt% of raw materials) in total was added and stirred with a special reactor, and reacted.

Moreover, the oil content in the raw material was 23.700 mg / kg (dry basis), and the component in the reaction product was 1.330 mg / kg (dry basis). The removal rate (reduction rate) of the water-soluble phosphoric acid according to the present example is 99.6%, and the removal rate (reduction rate) of the oil is 94.4%. Also in this embodiment, a significant reduction effect on the water-soluble phosphate fraction is recognized, and the characteristics of the second addition according to the present invention are clear.

Example 14

In this embodiment, an additive is added three times by dividing the weight by 1/3. 30kg (3.75% by weight of raw material) as the first addition amount to 800 kg of slurry of 89.0% by weight, which is a mixed ingredient of pig manure, meat processing facilities and surplus sludge in the slaughterhouse, as a raw material. As a result, 30 kg (3.75% by weight of the raw material) and 30 kg (3.75% by weight of the raw material) were added as the third addition amount, and 90 kg (11.25% by weight of the raw material) was added, followed by stirring in a special reactor. After 2 minutes had elapsed since the first addition, the second time was added a second time, and after the third addition, the reaction time was 12 minutes after the first addition. In said reaction, the temperature rise was 31.5 degreeC. The obtained reactant slurry was dried to obtain 335 kg of a reaction product having a water content of 38.5 wt%. The water-soluble phosphoric acid content in the raw material was 27.700 mg / kg (dry basis), while the component in the reaction product was 121 mg / kg (dry basis). In addition, the lipid content in the raw material was 34.600 mg / kg (dry basis), while the component in the reaction product was 2.200 mg / kg (dry basis). The removal rate (reduction rate) of the water-soluble phosphoric acid according to the present example is 99.6% and the lipid removal rate (reduction rate) corresponds to 93.6%. According to the present Example, the remarkable reduction effect with respect to water-soluble phosphate lipid in 3 addition examples is recognized.

Example 15

This example shows a comparative example with the above-described example 14, and under the same conditions, the additive is added once. As a raw material, add 90 kg (11.25% by weight of the raw material) of additives whose main component is quicklime, which has high activity, to 800 kg of slurry of 89.0% by weight, which is a mixture of pig manure and surplus sludge, and stir in a special reactor. The reaction was carried out for 12 minutes. In the reaction process, the temperature rise was 27.5 ° C. The reactant slaley obtained was dried to obtain 345 kg of the reaction product having a water content of 39.5 wt%. The water-soluble phosphoric acid content in the raw material was 27.700 mg / kg (dry basis), while the component in the reaction product was 228 mg / kg (dry basis). In addition, the lipid content in the raw material was 34.600 mg / kg (dry basis), whereas the component was 6.160 mg / kg (dry basis). The removal rate (reduction rate) of the water-soluble phosphoric acid according to the present example is 99.2%. The removal rate (reduction rate) of the lipid is 82.2%. As is clear from this example, the reduction effect is recognized for the water-soluble phosphate lipid even at one time addition, but the removal rate is lowered for the positive component as compared with the case where it is added three times. Next, the case of cultivation is shown when the soil improvement material obtained by the method which concerns on the above Example is used.

According to the present Example, it turns out that this soil improvement material works effectively also in 2 years like Example 19. As described above, the present invention stabilizes most of the total phosphoric acid contained in the perishable waste as an effective calcium phosphate by mixing the solid perishable perishable waste in a predetermined proportion by mixing an additive having a high active quicklime as a main component. Therefore, it is possible to produce soil improvers containing organisms in which calcium is dispersed. Therefore, this type of soil improvers is produced without taking a long time, and the resulting soil improvers are produced by pests or harmful substances due to unreacted residues. Since microorganisms are not generated and calcium is dispersed, that is, it is constituted as a complex in which minerals are suitably blended with organic matter, it has an active structure, hydrophobicity and water absorption with a monolithic structure, and facilitates ineffective ingredients. Not only can it be absorbed surely, but it can also increase intellect by continuing to be ineffective. Will.
