Consists of BEST MODE FOR CARRYING OUT THE INVENTION

Hereinafter, the configuration and effects of the present invention will be described.

The present invention provides a step of selecting an inorganic material excellent as a soil improvement, deodorizing effect, moisture control effect, fertilizer raw material, and determining the composition ratio of the industrial waste; and a step of producing a soil composition. A step of applying the composition for soil of the present invention to various crops to conduct an actual cultivation test in order to confirm a growth promoting effect and an effect of increasing the production amount, and evaluating the result or a step of evaluating the result. It is characterized in that it comprises a step of applying the composition to garbage processing, manure processing, decay processing, dehumidification processing, etc., and evaluating the water adjustment, deodorizing effect, and dehumidifying effect.

The industrial wastes selected in the present invention are pulp and paper sludge discarded in paper mills and fly ash generated from thermal power plants. Raw materials suitable for maximizing the water retention capacity of soil are Zeolite and diatomaceous earth. In place of this zeolite and / or diatomaceous earth, pinestone (trade name Glaston) can also be suitably used.

The fly ash selected in the present invention aims at supplying siliceous, aluminum, calcareous, iron, boron and the like. Therefore, fly ash, which is a constituent material of the composition of the present invention, plays a promoting role in the formation of soil aggregates, and ultimately maximizes the soil porosity. Fly ash is fine ash collected from the smoke that burns fine powder. The active ingredient as a fertilizer is boron, which contains 52-63% of Keiic acid. Its effect is high as a boron fertilizer, and Improve the root of Ne.

The major part of the papermaking sludge selected in the present invention is occupied by cellulose and lignin. In this case, for example, much of the cellulose is decomposed during the composting process, and the proportion of lignin and ash becomes significantly higher. The application of paper sludge is suitable for all crops. In addition, phosphoric acid fertilizer may be inferior due to the effect of aluminum nitrate. When using it for winter crops, it is recommended to apply 20 to 30% more phosphate fertilizer.

Diatomaceous earth, which is a fine powder of the constituent materials of the composition of the present invention, is a fine powder and has been selected because it has an effective action for producing a granular product of the product of the present invention by cross-linking with CMC which is an aqueous adhesive.

A preferred composition of the composition of the present invention is 10-90, preferably 20-80, more preferably 30-70% by weight of papermaking sludge, 10-80 of fly ash, preferably 20-75, more preferably 30 to 70 weight ^_0/0, Zeoraito (Zeolite) 5 to 50, preferably 10 to 40 wt%, diatomaceous earth 20-50, preferably 25 to 40 wt%, optionally aqueous adhesive for example CMC ( Carboxymethylcellulose) from 0.5 to 10, preferably from 1 to 3% by weight. This ratio means the ratio of each component when it is used, and it is not necessary to include all components.

Preferred examples of the composition of the present invention include the following combinations. % Means% by weight.

① Fly ash 10-50%, papermaking sludge 10-90%, CMC 0-3% ② Fly ash 50-70%, zeolite 10-20%, diatomaceous earth 20-30%, CMC 0-3%

③ Paper sludge 50-70%, zeolite 10-20%, diatomaceous earth 20-30%, CMC 0-3%

紙 Paper sludge 60-80%, diatomaceous earth 20-40%, CMC 0-3%

フライ Fly Ash 50-70%, Zeolite 30-50%, CMC 0

紙 Paper sludge 50-70%, zeolite 30-50%, CMC 0-3% ⑧Fly ash 10-20%, papermaking sludge 45-65%, diatomaceous earth 20-40%, CMC 0-3%

⑨Fly ash 10-50%, papermaking sludge 10-65%, zeolite 10-20%, diatomaceous earth 20-30%, CMC 0-3%

Here, diatomaceous earth and / or zeolite can use pinestone (graston) as a substitute in the same ratio. These compositions can be used as soil moisture regulators, soil conditioners, and fertilizer raw materials. Although the above ratio has been exemplified as being optimal, more favorable results can be obtained by performing quantitative adjustment according to soil conditions. Particularly suitable compositions are as follows: ①①③④⑦⑧ is useful as a soil moisture regulator and fertilizer raw material, and ②⑤⑥⑤⑥ is useful as a soil conditioner. In addition, the preparations (1) to (4) or the preparations excluding CMC from them are useful and effective in adjusting the water content, deodorizing, and dehumidifying garbage, manure, and putrefactive substances. Diatomaceous earth and Z or zeolite had the same effect if pinestone (glaston) was replaced in the same ratio.

In order to prepare the final fertilizer using the composition of the present invention as a fertilizer raw material, various natural fertilizer raw materials and the present composition are appropriately mixed. Natural fertilizer raw materials include raw garbage, squeezed waste after juice production of various fruits (eg, apples, mandarins, etc.), cow dung, horse droppings, fallen leaves, etc., but are widely applicable to what is called natural fertilizer. The mixing ratio is 0.01 to: L00 with respect to 1 of the composition of the present invention in terms of volume ratio. For example, in the case of mixing orange juice with squeezed residue, it is 1: 1 to 9 (1: 0.1 to 1 in weight ratio). 7), In the case of mixing with cow dung, 1: 0.:!-3 (weight ratio 1: 0.01-2) is preferably exemplified. The mixing method is not particularly limited, but it is preferable to use, for example, a rotary mixer in order to ensure a uniform mixing state. Mixing is possible at room temperature. After mixing, it must be added to the fermentation process in order to produce natural fertilizer. Fermentation is performed under appropriate temperature (eg, 15 to 28 ° C) with appropriate humidity and preservation treatment for about 20 to 90 days to achieve fertilization.

Use of the composition of the present invention for water control and deodorization of food waste, manure, and decay It is done by direct contact and mixing with food waste, manure and decay. For the treatment of garbage, a garbage disposer is mixed and filled with the composition of the present invention and treated. Cows, horses * Chickens For manure treatment of animals such as pigs, when manure is collected, it is mixed with the composition of the present invention and stored for one to several days. The treatment of garbage and various fruits (eg apples, mandarin oranges, etc.) after juice production, such as scum and other decay, is substantially the same as the treatment of manure. It is natural that the more the compounding ratio is, the higher the effect is for deodorization, but the composition of the present invention is preferably 0.01 to 1, more preferably 0.05 to 0, for 1 of the target substance. 5, optimally in a weight ratio of 0.1 to 0.3. When the composition of the present invention is used for moisture adjustment, it is determined by the following formula according to the target moisture percentage.

(Calculation formula for 1 ton of manure volume)

(Amount of moisture control material X moisture content of moisture control material X amount of manure) ÷ (amount of moisture control material + amount of feces and urine)

= Moisture requirement of manure Amount of water regulator: A kg

Moisture percentage of moisture control material: 7.8% = 0.078

Manure volume: 1 ton

Manure moisture content: 95% = 0.95

Manure volume: 1000kg

(A kg x 0.078 + 1 ton x 0.95) ÷ (A kg + 1000 kg)

= Required water in manure For example, when reducing the manure moisture rate from 95% to 85%, the amount of water regulator (material for water reduction) is set to A from this formula, and the following calculation is made, and it is determined that 129.53 kg is required.

(A kgxO.078 + 1 ton X 0.95) ÷ (A kg + 1000) = 0.85 A = 129.53kg When the water content ratio of manure is 95% reduced by 10%, the amount of water regulating material (material for water reduction) is as follows.

85% (required water content of manure) = 129.5 kg (material for water reduction)

80% / = 207.7 kg /

As described above, the composition of the present invention can appropriately adjust the mixing ratio for controlling water content.

When the composition of the present invention is used as a dehumidifier or a deodorant, a predetermined amount of the composition of the present invention is sprayed on a target space to be treated. Application rate is generally from 0.05 to 1, although preferred properly is 0. 5~1 Kg / m ^2, Ru appropriately changeable der the sealed space. Applications include under eaves, attics, spaces between floors, wall spaces, odor storage areas, and so on. When the composition of the present invention is used in combination with building materials, it can also function as a dehumidifier or a deodorant for rooms and buildings. In this case, the building material and the composition of the present invention are mixed and used directly as wall soil or the like. The composition of the present invention thus used exhibited an effective dehumidification / deodorization effect, for example, by spraying under the eaves. Example
