Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a deodorizing device, and its purpose is to utilize the humidifying and rinsing effects of conventional water for deodorizing, as well as to improve the aeration and evapotranspiration promoting effects of malodorous gases. The purpose of the present invention is to provide a deodorizing device that improves deodorizing ability and makes effective use of land by utilizing water for evapotranspiration.

Embodiments of the present invention will be described below with reference to the drawings.

In FIG. 1, 1 is a trench groove, and a water sprinkler pipe 2 is disposed approximately in the center thereof. Water is supplied to the water sprinkler pipe 2 and leaks to the outside through a number of small holes drilled in the outer circumference of the water pipe 2. A filler 3 such as gravel is filled around the sprinkler pipe 2,
The water leakage is quickly dispersed in all directions. Further, on the upper side of the filler 3 such as gravel, a sill 4 for preventing the fall of earth and sand is provided, and a covering soil 5 is backfilled on top of the sill 4. An impermeable structure 6 is disposed at the bottom of the trench 1 below the sprinkler pipe 2 and the filler 3 such as gravel, and sand 7 is filled between the filler 3 such as gravel.

A filling material 8 such as gravel is installed below the trench groove 1, and an aeration pipe 9 is placed in the filling material 8. A foul-smelling gas is supplied to the air diffuser pipe 9, and is diffused through a small hole 10 drilled in the lower side into the external filling material 8, such as gravel, to the sides of the trench groove 1. It is diffused into the soil 11.

Since this embodiment is configured as described above,
The water passed through the sprinkler pipe 2 leaks from the small holes into the external filling material 3 such as gravel. The leaked water is further infiltrated into the covering soil 5 and the soil 11 as shown by arrow A. A portion of the water infiltrated into the soil 11 rises to the soil surface by capillary action as shown by arrow B, and is evaporated into the atmosphere. The remainder of the water infiltrated into the soil 11 moves laterally and downward as shown by arrow C, and penetrates into the groundwater layer through the filler 8 such as gravel.

On the other hand, the foul-smelling gas sent into the air diffuser pipe 9 is diffused through the small hole into the filling material 8 such as gravel,
It is dispersed as shown by arrow D by a filler 8 such as gravel.
The dispersed malodorous gas further flows into the soil 11 as shown by arrow E.
It penetrates inside and rises.

As water and foul-smelling gas move in the manner described above, water comes into contact with foul-smelling gas while moving particularly through the soil 11 and filler 8 such as gravel, and the oxygen in the gas increases the activity of aerobic microorganisms. The soil is actively decomposed and digested by this, and water is evaporated and absorbed into the gas and released from the soil surface. When the temperature of the malodorous gas is high, the transpiration effect becomes more active, and the treatment is carried out more quickly and heat is absorbed into the soil.

In addition, when the foul-smelling gas comes into contact with the capillary infiltrated water, it is humidified and the foul-smelling particles are captured in the water, which is then adsorbed into the moist soil and undergoes _a decomposition action ^. ₄ ^--, etc.) is rinsed with water, becomes odorless, and is diffused from the soil surface into the atmosphere.

FIG. 2 shows another embodiment of the device of the present invention. In the embodiment shown in FIG. A diffuser pipe 9 is placed between them.

The effects of the present invention are listed below.

(b) The humidification effect necessary for deodorization by capillary infiltration water is expected.

(b) Malodorous decomposition products (NO ₃ ^- ,
The rinsing effect of SO ₄ ^-- etc.) can be expected.

(c) It is possible to maintain aerobic conditions in the soil by aerating foul-smelling gases.

(d) Water evapotranspiration is promoted by aeration of foul-smelling gases.

(e) Land can be used effectively.
