BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, the present invention will be described in detail. The pearlite ore according to the present invention has a particle size of 0.1 to
10 mm, preferably 1 to 3 mm is used. The particle diameter of the expanded pearlite is 0.1 to 15 mm, preferably 0.5 to 5 mm. It is excellent in deodorizing and dehydrating effects because it has a large aeration property and also has excellent soil permeability. Here, the particle size of the expanded pearlite is 0.5
When the diameter is smaller than mm, the air-holding property tends to increase, and when the diameter exceeds 5 mm, the foaming ratio generally decreases, and it becomes difficult to obtain a large number of micropores. The pearlite according to the present invention has concentric, elliptical or polyhedral cracks,
Rhyolite glassy volcanic rock with pearly luster.

The filth and sewage of the present invention are not particularly limited, but include manure, livestock manure of cattle, horses, sheep, pigs, and other livestock, residues and effluents of food processing plants, effluents of shochu production plants,
It is preferably used for sewage sludge and agricultural, forestry and fishery waste. These are rich in fertilizer active ingredients, and when treated with sewage and sewage treatment materials, the active ingredients are adsorbed in the pores of perlite and slowly released into the soil, so that a long-term fertilization effect is obtained. be able to. In addition, since the alkali component is also slowly adsorbed to the pores and released slowly, they have an effect that they can activate the soil in combination. In the present invention, since exothermic reaction with quicklime requires moisture, it is preferable to use excrement of livestock such as cattle, horses, sheep, and pigs having a moisture content of 95% or more. Chicken manure adjusted to 90% or more may be used. By the method for treating waste and sewage according to the present invention, a soil activator, an organic fertilizer, and the like can be obtained and used for various uses.

The soil activator, organic fertilizer, and the like are applied to agricultural fields such as paddy fields, fields, orchards, and tea fields for agriculture, home gardens, and garden pots. The material for treating sewage and sewage according to the present invention, the method for treating sewage and sewage contains zeolite, vermiculite, ferrite, soft silica, montmorillonite, clay ball, and other other components within a range that does not impair the purpose of the present invention. Can be done. This is because the water permeability and air permeability of the soil can be improved, and the fertilization state of the treated material can be improved.

The waste and sewage treatment material comprises 3 to 20 parts by weight of quicklime, preferably 5 to 10 parts by weight, and 0.2 to 100 parts by weight of perlite.
10 parts by weight, preferably 1 to 5 parts by weight, more preferably 2 to 4 parts by weight are mixed. Here, as the amount of quicklime becomes less than 5 parts by weight with respect to 100 parts by weight of the suspension-like or slurry-like filth / sewage, the calorific value obtained by the exothermic reaction with moisture is smaller, and thus the dehydration and sterilization effects are less likely to occur. However, if the content exceeds 10 parts by weight, the amount of slaked lime increases, depending on the amount and properties of sewage and sewage. In particular, if the amount of quicklime is less than 3 parts by weight or more than 20 parts by weight, this tendency is remarkable, which is not preferable. Further, as the content of pearlite is less than 2 parts by weight, the deodorizing and dehydrating functions become difficult to work, and as the content exceeds 30 parts by weight, the pearlite becomes difficult to become completely integrated and the processed product tends to be in a lump, Is also not preferred. In particular,
If the pearlite content is less than 0.2 parts by weight or more than 10 parts by weight, this tendency is remarkable, so that it is not preferable.

The pearlite according to the present invention is prepared by converting a pearlite ore to a temperature of 1000 ° C to 1500 ° C, preferably 1100 ° C to
It is heated to 1400 ° C., more preferably 1200 ° C. to 1350 ° C. to foam, and the expansion ratio is 5 to 20 times, preferably 7 times.
The foam is foamed up to 15 times, more preferably 8 to 11 times. Here, as the heating temperature becomes lower than 1200 ° C., the pearlite ore is hardly foamed, so that the dewatering and deodorizing effects become smaller, and as the heating temperature becomes higher than 1350 ° C.,
Either is not preferred because of the tendency to powder. In particular, the heating temperature of the pearlite ore is less than 1000 ° C or 1
If the temperature is higher than 500 ° C., this tendency is remarkable, which is not preferable.

Further, as the expansion ratio of perlite becomes smaller than 7 times, the porosity of perlite becomes smaller, and the dewatering and deodorizing effects of perlite become smaller, which is not preferable. None of them is preferable because they tend to be difficult to obtain.
In particular, if the expansion ratio of pearlite is less than 5 times or more than 20 times, this tendency is remarkable, so that it is not preferable.

The coal according to the present invention is added and mixed in an amount of 0.001 to 0.1 part by weight, preferably 0.01 to 0.08 part by weight. Here, as the amount of coal is less than 0.01 parts by weight, the deodorizing effect is reduced, and as the amount is more than 0.08 parts by weight, it becomes difficult to obtain a synergistic effect by the charcoal, and thus both are not preferable. In particular, if the amount of charcoal is less than 0.001 part by weight or more than 0.1 part by weight, this tendency is remarkable, which is not preferable. As the charcoal, charcoal, bamboo charcoal or the like is preferably used.

For 100 parts by weight of filth / sewage,
Mixing the sewage treatment material in an amount of 3 to 30 parts by weight, preferably 6 to 20 parts by weight, is preferable because dried granules are obtained, and odor is reduced and work efficiency is improved. Here, as the amount of the filth / sewage treatment material is less than 6 parts by weight with respect to 100 parts by weight of the sewage / sewage, dehydration, deodorization, and sterilization are reduced, which is not preferable. This is not preferred because the alkalinity is increased and the processed product tends to be agglomerated. In particular, if the amount of the filth / sewage treatment material is less than 3 parts by weight or more than 30 parts by weight with respect to 100 parts by weight of the sewage / sewage, this tendency is remarkable, which is not preferable.

To 100 parts by weight of filth / sewage, 3 to 2 quicklime
0 parts by weight were added and mixed.
0 parts by weight, and 0 to 0.1 parts by weight of charcoal added and mixed,
The treated product can be obtained by pulverization, and is excellent in fertilization workability and is preferable. Here, as the amount of quicklime decreases to less than 3 parts by weight with respect to 100 parts by weight of filth / sewage, the heat of reaction with water is reduced, and thus the water is less likely to evaporate, and the sterilizing action due to heat generation is reduced, which is not preferable. . On the other hand, if quicklime is contained in excess of 20 parts by weight with respect to 100 parts by weight of filth and sewage, slaked lime increases, which is not preferable.

Further, if the content of perlite is less than 0.2 parts by weight with respect to 100 parts by weight of filth / sewage, the effect of dehydration and deodorization of perlite decreases, and the effect cannot be expected. On the other hand, perlite or perlite and charcoal are based on 100 parts by weight of filth and sewage.
If the content exceeds 0.2 to 10.1 parts by weight, the resulting treated product tends to be in a lump, which is not preferable.
