[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for deodorizing malodorous substances. More specifically, the present invention relates to a method for deodorizing and decomposing odors generated from livestock manure and marine wastes using soil microorganisms to supply air to the ground surface. The present invention relates to a method for deodorizing a malodorous substance by soil microorganisms to be used.

[0002]

2. Description of the Related Art Odors generated from human dung, livestock excreta, wastewater, sludge, garbage, etc. are regulated by the Odor Control Law and by their content ratio in the atmosphere (see Table 1).
Have been. Various deodorizing methods and deodorizing methods have been studied in order to comply with the regulations.

[0003] For example, there is a chemical cleaning method in which an odor gas is brought into contact with an aqueous solution of a drug to absorb and remove the odor gas and to convert an odorous substance into an odorless substance by a chemical reaction with the chemical, and the chemical used is hypochlorous acid. An oxidizing agent such as soda, an acid, or an alkali is used. When the concentration of odorous substances is low and the odor cannot be completely removed by washing with a chemical solution, a deodorizing method by an adsorption method is used, and activated carbon having a large adsorption capacity is mainly used as an adsorbent to be used. In this adsorption method, the adsorption capacity of the adsorbent is limited, and it is necessary to perform a desorption operation for removing odorous substances from the adsorbent before exceeding the limit.

Furthermore, soil deodorization methods have been studied for a long time and have been used in various ways. This deodorizing method is a biological deodorizing method for deodorizing by using microorganisms or enzymes that oxidatively decompose odorous substances, and is a method of introducing odor into soil to deodorize. For example, as shown in FIG. 3, a layer having a good air permeability and water retention is selected and the layer height is set to about 50 cm in order to reduce the air flow resistance. Since the apparent ventilation speed required for removing odors is limited to 5 to 10 m / S, a considerably large apparatus floor area is required as compared with the ventilation amount, and in fact, ventilation tends to occur after heavy rain. Therefore, detailed management of the device is required. In the figure, 21 is an air duct, 22 is an air duct, 23 is a blower,
24 is a main airway, 25 is a cobblestone, 26 is a cold gauze, 27 is soil and D is an odorous gas.

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 and FIG. 2 show a method or mechanism for deodorizing a malodorous substance by a soil microorganism according to the present invention. In the figure, 1 is an odor intake, 2 is an air intake, 3 is a drain separator, 4 is an air filter, 5 is a blower, 6 is an odor introduction pipe, 7 is an odor reservoir, 8 is a measuring instrument, 9
Water supply, 10 is a drainage pump, 11 is a crushed stone holding plate, 12 is a crushed stone layer, 13 is a soil layer, 14 is the ground surface, 15 is a measuring instrument,
16 is an inspection port, A is an odor, B is air and C is exhaust.

First, an odor substance treatment place is set, excavated deep in the ground, and buried in an odor storage chamber 7 at the bottom of which an odor introduction pipe 6 is connected. Next, a drainage pump 10 is connected to the odor storage chamber 7 so that the water supply 9 can flow in. On the other hand, a blower 5 is provided inside the odor introduction pipe 6, and an air filter 4 and a drain separator 3 are provided inside. Reference numeral 8 denotes a measuring instrument including a pressure gauge, a thermometer, and a moisture meter attached to the odor introduction pipe 6, and reference numeral 15 denotes a measuring instrument for measuring the ground surface.

Next, a deodorizing treatment mechanism for a malodorous substance according to the present invention will be described. First, the odor A with strong odor and the fresh air B are sucked from the odor intake port 1 and the air intake port 2 at the tip of the odor introduction pipe 6. The fresh air B and the odor A are mixed into the drain separator 3 to separate the odorous substance into solids and water, and then fine solids are further removed through the air filter 4. The removed odorous substance is introduced into the odor introduction chamber 6 downward by the blower 5 and sent into the odor storage chamber 7. Then, the odor substance sent into the odor storage chamber 7 flows into the water supply 9 by the drain pump 10 to mix and decompose the water and the gas. The decomposed odor substance is absorbed and diffused into the crushed stone layer 12 and the soil layer 13 through the crushing holding dish 11 and digested and decomposed into energy. In this way, the deodorized or deodorized substances digested and decomposed are discharged and supplied to the ground surface 14. By supplying the air C to the ground surface 14, the air B in which the strong odor of the odor is made odorless can be exhausted C into the air.

At this time, since the area of the crushing layer 12 is larger than that of the odor reservoir 7, the odor A enters both vertically and horizontally and is simultaneously diffused into the upper soil layer. Then, the odorous substances are brought into contact with soil microorganisms until they reach the ground surface, and the odorous substances are assimilated and deodorized.

Further, the deodorizing method of the present invention can be explained from the following theoretical configuration. A, If the pressure at which air is blown into the underground odor storage chamber 7 is p1, the radius of the odor introduction pipe 6 is r1, and the radius of the odor storage chamber 7 is r2, the pressure p2 of the odor storage chamber 7 is p2 = p1 * πr1. ² / πr
3 so ² become, so that the odor A is diffused crushed stone pan 11 as crushed stone layer 12. B. Let the radius of the crushed stone layer 12 be r3 and the pressure at that time be P3.
Since the ^{P3 = P1 * πrl 2 / πr3} 2 if,
The odor A is diffused into the soil layer 13 above the crushed stone layer 12 and reaches the ground surface 14. C, the radius of the diffusing surface 14 so the pressure at that time becomes ^{p4 = p1 * πr1 2 / πr4} 2 if p4 as r4, that this is in the soil there are hundreds of millions of soil microorganisms in 1g Become. Then, the odor A comes into contact with the soil microorganisms when the soil layer 13 in which the soil microorganisms are present is diffused from below at a pressure of p3 to p4. D. As a result, the soil microorganisms digest the odorous substances as energy and absorb and decompose them, so that the odorous substances are deodorized to an odorless state, and continue to spread as fresh air B, thereby spreading the ground surface 14.
And diffused into the atmosphere.

Table 2 shows experimental data obtained by the method of the present invention.
