DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an insect repellent for organic fertilizers for controlling maggots and the like generated when ripening organic fertilizer.

[0002]

2. Description of the Related Art Organic fertilizers do not cause soil fertilization or burning, and can grow crops better than fast-acting chemical fertilizers, increase yields, and fertilize lean soil due to excessive use of chemical fertilizers. Therefore, the application of organic fertilizer is encouraged. When the organic fertilizer is ripened, the straw and sawdust laid on the livestock are collected in a compost bar and fermented and decomposed for about 3 to 4 months to ripen the organic fertilizer. Also, at home, in order to recycle garbage discharged from the kitchen into organic fertilizer, a garbage disposal tank made of polyethylene is installed in the garden of each household, and the garbage disposal tank is placed in the garbage disposal tank. The garbage is fermented and decomposed while being thrown in sequentially, composted in about three months, and used as organic fertilizer in garden trees and vegetable gardens in homes.

[0003]

However, maggots are produced when the litter or sawdust of the barn is ripened in the compost bar, or when the garbage is fermented and decomposed in the garbage disposal tank. Even if pesticides are sprayed on the upper surface of raw material and garbage during ripening, maggots cannot penetrate into the organic fertilizer and thus cannot be killed, so that fermentation and decomposition of organic fertilizer is suppressed, and There have been problems such as the fact that the winged maggots fly into the nearby houses and homes and easily create an unsanitary environment.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned conventional problems, and has as its object to mix and germinate maggots living in raw materials by mixing them into the raw material during ripening. To provide an insecticide for organic fertilizers that can prevent the occurrence of flies, reduce the environmental pollution of neighboring houses and homes, and can also be used as an organic fertilizer without inhibiting fermentation decomposition as a fertilizer. It is in.

[0005]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention provides an organic sludge 10 as a main material and a granular molding method.
The molded particles are immersed in an insecticide solution 24 and dried to constitute an insecticide 28 of an organic fertilizer.

[0006]

The insect insecticide in the organic fertilizer according to the present invention comprises:
After dehydrating and drying organic sludge such as domestic sludge discharged from domestic wastewater treatment plants or excess sludge contained in wastewater from the fermentation industry, food industry, etc., it is fermented and decomposed by air laying. Is granulated. The molded particles are immersed in an insecticide solution and dried. This particulate insecticide is mixed with raw materials that are maturing in a compost house or garbage that is being fermented and decomposed in a garbage disposal tank, so that the insecticide impregnated while being fermented and decomposed together. The agent is gasified by fermentation heat and penetrates into the organic fertilizer to kill and eradicate maggots and the like living in the raw material. As a result, fermentation and decomposition of the organic fertilizer during ripening is promoted, and the environment such as a house near a compost building and a home provided with a garbage disposal tank can be improved without generating fly. Furthermore, the insecticide itself can be used as an organic fertilizer.

[0007]

Preferred embodiments of the present invention will be described below with reference to the accompanying drawings. FIG. 1 is a production process diagram of an insecticide for organic fertilizers according to an embodiment of the present invention. As is clear from the figure, the insecticide of organic fertilizers is obtained by using a rotary dryer to remove the organic sludge 10 discharged from a wastewater treatment plant for domestic wastewater or a wastewater treatment plant for the fermentation industry or food industry. Dehydration 12 is performed to a water content of about 60%. The dewatered organic sludge 10 is mixed 18 with animal dung 14 such as cow dung and chicken dung and wood debris 16 such as sawdust and bark to replenish the dung and fiber components. Suitable mixing ratio (weight ratio)
For example, 30 parts of animal dung 14 and 10 parts of wood dust 16 are mixed with 60 parts of organic sludge 10. The mixture is dried with a rotary dryer to a water content of about 30%. While air is passed through the mixture for about 24 hours, animal dung 1
Each component in the mixture is fermented and decomposed 20 by bacteria living in 4. The powdery mixture obtained by the fermentation decomposition 20 is granulated 22 to a radius of about 6 mm and a length of about 10 mm. Further, the granulated product 22 is immersed in an insecticide solution 24 diluted about 200 times for 2 to 3 minutes and pulled up.
The dried product is provided as an insecticide 28. This insecticide 28 is, for example, as shown in FIG.
In a garbage disposal box 36 in which a drain hole 32 is opened in the bottom part 30 and mounted on a support base 34 such as a block, a fermentation promoter 3 such as compost sprayed on the inner bottom surface of the same garbage disposal box 36.
8 may be mixed. By accommodating garbage 40 discharged from homes and the like in the garbage disposal box 36 and sealing the upper surface of the garbage disposal box 36 with the lid 42, the insecticide 28 as well as the fermentation decomposition of the fermentation accelerator 38 The insecticide solution that has been decomposed and impregnated in the insecticide 28 penetrates into the garbage 40 while being gasified by the fermentation heat, and accurately kills and eradicates maggots and the like hatched in the garbage 40. Therefore, no maggots are generated in the garbage 40 that is being fermented and decomposed into organic fertilizer in the garbage disposal box 36, fermentation decomposition as an organic fertilizer is promoted, no fly is generated, and the living environment in the vicinity is improved. it can.
In addition, even in the organic fertilizer that is maturing in a compost house, by mixing the insecticide 28 of the present invention therein, maggots can be killed and eradicated, and fermentation and decomposition of the organic fertilizer are promoted. The environment can be improved. Further, the insecticide 28 may also serve as an organic fertilizer itself. In the examples, the organic sludge is granulated, but may be dried into a powder and mixed with an insecticide.

[0012]

As described above, the insecticide for organic fertilizers according to the first aspect is formed by granulating organic sludge as a main material, immersing the formed granules in an insecticide solution and drying. The formation of maggots can be prevented by mixing into the raw material during ripening, and the fermentation decomposition as organic fertilizer is not suppressed. Pollution can be reduced, and it can also be used as an organic fertilizer.
