強制的に通気させて脱臭するのであるから、一般
の物理的、化学的脱臭処理に比較して、小面積で
多積の悪臭気体を処理することが困難であつた。 Various types of deodorizing devices using soil have already been developed by the present inventors, and their value as a resource-saving and energy-saving deodorizing method has been fully evaluated by society. However, since the soil deodorization described above deodorizes by forcing air between soil particles, it is possible to treat a large amount of malodorous gases in a small area compared to general physical and chemical deodorization treatments. It was difficult.
最近における悪臭問題は、広い敷地を有する工
場、住宅、処理場等では被害は少なく、社会紛争
にまで発展するのはむしろ狭い面積で悪臭発生施
設の場合が多く、上記土壌による脱臭装置の改善
が要請されていた。 In recent years, the problem of bad odors has caused little damage in factories, residences, treatment plants, etc. that have large sites, and it is often the facilities that have small areas that generate bad odors that have led to social conflicts. It had been requested.
本発明は上記要請に応えるためになされたもの

土壌による脱臭兼用汚水浄化方法を提供するにあ
る。 The present invention was made in response to the above-mentioned needs, and its purpose is to effectively utilize ground space by layering soil, improve deodorizing ability in narrow sites, and to It is an object of the present invention to provide a soil-based deodorizing and sewage purification method that can promote the sewage purification effect by culturing microorganisms and supplying them to a sewage treatment tank located below the stratified soil.
以下、本発明の一実施例について図面を参照し
ながら説明する。 An embodiment of the present invention will be described below with reference to the drawings.

気孔である。 In FIGS. 1 and 2, 1 is a cylindrical layered unit, and a ventilation pipe 2 is provided in the center thereof. A support plate 3 with a large number of small holes 3a is installed at the middle position and bottom of the stratification unit 1, and a support plate 3 with a large number of small holes 3a is installed therein.
Soil 5 is filled on top of it. A space 6 is formed between the support plate 3 at the intermediate position and the lower soil layer 5, and a space 6 is formed between the support plate 3 at the intermediate position and the soil layer 5 at the lower side.
The bad odor is supposed to enter through a. 1a is an exhaust hole.

足栄養分を連続的に供給するようになつている。 FIG. 3 shows a large number of the stratified units 1 stacked along the wall of a house 7, with a sewage septic tank 8 installed below. Reference numeral 9 is a forced ventilation fan, which blows the bad odor from the septic tank 8 into the ventilation pipe 2 of the stratification unit 1. Reference numeral 10 denotes a watering device, which continuously supplies the soil 5 in the stratified unit 1 with moisture necessary for culturing microorganisms and deficient nutrients including trace elements.
本実施例は以上のようになつているので、上述
のように散水装置10から水や栄養分を土壌5に

水浄化槽8からの悪臭は第2図に示すように通気
管2に送られる。 Since this embodiment is configured as described above, if the forced ventilation fan 9 is operated while continuously supplying water and nutrients to the soil 5 from the watering device 10 as described above, the bad odor from the sewage septic tank 8 will be reduced as shown in Figure 2. The air is sent to the ventilation pipe 2 as shown in FIG.
通気管2に入つた悪臭はその通気管2aを通つ

れ、脱臭処理を受けて後、下方支持板3の小孔3
aからユニツト1の下方に排出する。 The bad odor that has entered the ventilation pipe 2 is evenly distributed into the space 6 through the ventilation pipe 2a. A part of the bad odor in the space 6 enters the soil 5 from the surface of the lower soil layer 5, and the bad odor components are adsorbed and captured by soil particles, and after being subjected to deodorization treatment, they are absorbed into the small holes of the lower support plate 3. 3
It is discharged from a to the bottom of the unit 1.
一方、空間部6内の悪臭の残りは中間部の支持
板3の小孔3aから上側土壌層5内に入り、上記
と同様に脱臭処理を受けて後、その表面から排出
する。 On the other hand, the remainder of the foul odor in the space 6 enters the upper soil layer 5 through the small holes 3a of the support plate 3 in the intermediate portion, undergoes deodorization treatment in the same manner as described above, and is then discharged from the surface thereof.
成層ユニツト1の上端部には排気孔1aが形成
されているので、該ユニツト1を第3図のように
積重ねた状態では、上記土壌5表面からの排気と
共に上側ユニツト1の下面からの排気もいつしよ
に該排気孔1aから大気中に排出される。 Since an exhaust hole 1a is formed at the upper end of the stratified unit 1, when the units 1 are stacked as shown in FIG. It is always discharged into the atmosphere from the exhaust hole 1a.
また、土壌5中には上方から水分及び栄養分が
連続的に供給されるので、微生物が繁殖し、流下
水分等と共に汚水浄化槽8中に滴下供給されて汚
水浄化に役立つ。 In addition, since water and nutrients are continuously supplied into the soil 5 from above, microorganisms proliferate and are dripped into the sewage purification tank 8 together with flowing water, thereby contributing to sewage purification.

生物の活動を盛んにするため温水としても良い。 Although the layered unit 1 is formed in a cylindrical shape, the present invention is not limited to this, and may be in any shape such as a quadrangle or a polygon. Further, the forced draft fan 9 is not necessary if the tank 8 is a blow tank and is already equipped with a blower or the like, or if it has a completely sealed structure such as a septic tank. The thickness of the soil layer 5 is, for example, about 20 cm, and its particle structure is preferably a mixture of volcanic ash and perlite that can maintain some degree of air permeability even when a large amount of water drops pass through it. Furthermore, during the above water sprinkling,
Lime water may be mixed in as a measure against NOx, or hot water may be used to increase microbial activity.

能力を向上せしめ得る利点がある。 As described above, the present invention stacks soil layers in a tower shape in the atmosphere, performs deodorizing treatment by aerating bad odors into the soil layers, and drains a microbial culture solution into the soil layers to remove sewage from below. Because it is dripped into a septic tank, it is not only possible to effectively deodorize a large amount of bad odors in a small area, but it can also be discharged into the upper atmosphere and diffused and diluted, eliminating pollution and making use of the soil at the same time. This has the advantage that the microorganisms can be cultured and supplied to the sewage purification tank below, thereby improving the purification ability.
