The challenge is to control the explosive generation of decay and decaying odors, such as soil deodorization related to organic waste treatment such as food residues, soil deodorization related to livestock waste treatment, and odors in landfills after killing of foot-and-mouth disease countermeasures.

  An object of the present invention is to solve the above problems.

  In order to solve the above-mentioned problems, in the present invention, one or more porous materials are loaded with an antibacterial agent or a single component of an antifungal agent to maintain a long-term antibacterial and antifungal effect, Organic waste in the soil, livestock dung, slag, coal ash, limestone, etc. are used to control the decay and decay of livestock slaughtered bodies. By constructing a soil deodorant that helps the effect of antibacterial and antifungal agents with auxiliary components that compensate for the outflow of alkali, and inserting the soil deodorant into the topsoil, a long-term aseptic environment in the soil in the soil The soil deodorization work will be carried out to prevent explosive organic matter decay and decay, thus fundamentally suppressing the generation of odors.

  The soil deodorizing material of the present invention is formed by loading or coating an antibacterial agent and fungicide on a porous material such as zeolite, silica gel, pearlite, diatomaceous earth, pumice, activated carbon, charcoal, etc. However, it is not advantageous to construct a complete antibacterial and sterilized environment in the soil for the purpose of soil deodorization.

  The present invention suppresses the explosive growth of spoilage bacteria by applying a soil deodorizing material having excellent antibacterial and antifungal effects to an appropriate part of the soil, while being sterile or aerobic near the soil surface layer. By constructing a layer in which fungi tend to live, the effect of general aerobic soil fungi is utilized to maximize the effect of deodorization.

Since the soil deodorizing environment constituted in the soil according to the present invention does not make all soil layers sterile, the soil environment in which bacteria necessary for changes in the types of malodorous components and fluctuations in the amount of generation are relatively inhabited The result is to prepare.

It is a soil deodorization construction sectional view concerning one embodiment of the present invention.

  The present invention will be described below with reference to the drawings. FIG. 1 is a soil deodorization construction sectional view according to an embodiment of the present invention. In this figure, the soil and alkali material mixed with soil deodorant material are covered by 2m from the surface of the countermeasure soil to which organic waste or sacrificial material has been introduced. Shows the state covered with soil.

  As a soil deodorant, at least one of porous materials including zeolite, silica gel, pearlite, diatomaceous earth, pumice, activated carbon, charcoal carries an antibacterial agent, a fungicide alone or a plurality of components, and a long-term antibacterial, It should have a fungicidal effect.

  When burying dead animal corpses that have been killed in the soil, cover the corpse with a normal blue sheet, etc., spray slaked lime, etc., and fill most of the burial mouths with normal soil. Further, among the soil of 2 m of the surface layer left without being backfilled, half of the soil deodorizing material of the present invention is soaked into the soil from (approximately) 5% to (approximately) 75% of the soil volume. In addition, the embedding port is filled with sufficient agitation and uniform condition. Finally, the soil that has not been processed on the outermost surface of the soil containing the soil deodorizing material is covered and the construction is completed.

Preferably, general soil is further added to the surface layer of the soil that has been constructed by the soil deodorizing construction method to create an active layer of aerobic microorganisms.

In soils that have already been buried, covered with organic waste, etc., and have generated odors such as spoiled odors, only the excavation of the surface soil will dissipate further odors. After spraying 10 kg of soil deodorant material per m ^{2 and} leaving it for about two weeks, changing the surface soil to an antibacterial state, excavating about 50 cm from the surface layer again, soil deodorant of 20 kg to 80 kg per m ² Sprinkle over the area and finally cover with surface soil.

In addition to the application of the soil deodorizer, an alkali material such as slag, coal ash, slaked lime, coral fossil, or limestone may be appropriately added during the above construction.

In the above, the soil deodorizing material may be granulated and / or solidified.

As explained above, antibacterial and antifungal agents alone or multiple components are supported on one or more porous materials to maintain long-term antibacterial and antifungal effects, and organic waste in the soil Slag, coal ash, limestone, etc. are used to control the decay and decay of livestock excrement, livestock excrement, and slaughter. By constructing a soil deodorant that helps the effect of antibacterial and antifungal agents depending on the ingredients, and soaking the soil deodorant into the topsoil, ensuring a long-term aseptic environment in the soil, explosive organic matter Soil deodorization work is carried out to suppress rot and decay, thus fundamentally suppressing the generation of odor.

Tobermorite 1t, which is a porous calcium silicate hydrate showing a BET value of 50 to 70 m ² / g, is dried with warm air and sprayed with Prom 20L, an antibacterial and antifungal agent made by With You Co., Ltd., from its air misty nozzle. Repeat the agitation to load the chemical on the entire surface and dry it to make a soil deodorant.

10 g of the prepared soil deodorant was precisely weighed, 500 mL of purified water was added, and the mixture was stirred for 6 hours and subjected to an elution test. The concentration of TBZ, one of the promol components, in the eluate was measured and found to be 3 ppm or less. As a comparative test, the same loading operation was performed on silica gel, and an elution test was performed. However, an elution test result of 200 ppm or more was obtained, and it was judged that long-term deodorization performance was not obtained in combination with promol.

  As a result of supporting 10 kg of mold anti-mold coating agent Molseal manufactured by Moltec Co., Ltd. on 1 t of dry silica gel, elution of components could not be confirmed even in the elution test.

  Deodorant systems such as a soil deodorization plant attached to a water treatment plant are expected to have a great deal of aerobic fungal activity. In many cases, a deodorizing effect cannot be obtained. In addition, the soil deodorization system once damaged required a long time for recovery. The soil deodorizing material and the soil deodorizing construction method of the present invention exert a tremendous effect in expanding the capacity of such a soil deodorizing system. Therefore, the present invention has economic value and can be used industrially.
