Description

【0001】
【発明の属する技術分野】
本発明は、大気や排ガス中に含まれる悪臭物質等を生物学的に処理する技術に関する。特に、設備費、運転費が安価で、安定した高い除去効率で処理することが可能な空気浄化装置に関する。
【0002】
【従来の技術】
従来の技術として、充てん塔式の生物学的空気浄化装置の代表例を図2に示す。この装置は、担体充てん層14と散水設備12から構成されている。悪臭物質等を含む原ガスは、15より入り、担体充てん層14を上向き流で通過する間に悪臭物質等が吸収、吸着、及び担体に付着した微生物により分解処理され、16より排出される。散水設備12は、担体に付着した塩類や生成物の洗浄と、微生物の生息、維持に必要な水分補給を行うために設けられている。ここに示す散水設備12は循環方式であり、充てん塔1の底部の循環水槽2に溜まった循環水3は、ポンプ6で汲み上げられ、担体充てん層14の上方より散水され、担体充てん層14を通過後落下して、循環水槽2に戻る。循環水槽2へは補給水4を補給して塩類濃度を一定に保持すると共に、カセイソーダ5を注入してpH調整を行う。このような装置の問題点としては、循環水の水質管理が煩雑である、装置の運転に際し、多量の補給水4や多量のカセイソーダ5を必要とする、循環水3を繰り返して長時間使用することにより、循環水3中に微生物が必要とする水素供与体等の養分が不足してしまい、担体充てん層14の微生物の活性化が低下し、悪臭物質等の除去効率が低下する、等が挙げられる。
【0003】
また、設備費、運転費が安価で、大気や排ガス中に含まれる悪臭物質等を除去する従来の技術に土壌脱臭法があるが、この方法の問題点としては、除去効率が悪いため、広いスペースの土壌が必要となる、長期間の使用により土壌中の生息微生物の活性化が低下し、脱臭効率が低下する、降雨等、自然条件下で脱臭が行われるため、除去効率が不安定である、等が挙げられる。
【0004】
【発明が解決しようとする課題】
本発明は、上述の問題点に鑑みてなされたものであり、解決すべき課題としては、従来の充てん塔式生物脱臭法と土壌脱臭法の2つの処理を同時に行うことを可能とし、担体充てん層に散水する水の水質管理を行う必要がない、カセイソーダ等の薬品は一切使わない、ポンプ等の動力設備を使用することなく、担体充てん層の微生物の活性化を高めるために必要な水分や水素供与体等の養分を常時一定量補給する、等が挙げられる。本発明の目的とするところは、これらの課題を達成することにより、従来の充てん塔式生物脱臭法と土壌脱臭法の2つの処理の利点を共有し、設備費、運転費が安価で、大気や排ガス中に含まれる悪臭物質等を安定した高い除去効率で処理することが可能な空気浄化装置を提供するにある。

【0023】
本発明は、雨水や融雪水を貯えて,この水を担体充てん層に散水するため、安価で、多量に使用することができる。また、塩類濃度の一定保持やpH調整等の管理を行う必要がない。
【0024】
また本発明では、培養土層を通過させて培養土中の養分等を取り込んでいる水を担体充てん層に散水するため、担体充てん層の微生物に養分等を供給することができ、微生物の活性化が高められ、悪臭物質等の除去効率が上がる。
【0025】

For example, a constant amount of nutrients such as a hydrogen donor is constantly replenished. The object of the present invention is to achieve these problems, thereby sharing the advantages of two treatments of the conventional packed tower type biological deodorization method and the soil deodorization method. Another object of the present invention is to provide an air purifying apparatus capable of processing malodorous substances and the like contained in exhaust gas with a stable and high removal efficiency.
[0005]

[0011]
DETAILED DESCRIPTION OF THE INVENTION
Next, a preferred embodiment of the present invention will be described in detail with reference to FIG. FIG. 1 is a schematic longitudinal sectional view of a biological air purification apparatus using rainwater and culture soil in which a part of a packed tower is installed underground. As shown in FIG. 1, the apparatus includes a rainwater storage tank 11, a watering facility 12, a culture soil layer 13, and a carrier packed layer 14. The rainwater storage tank 11 is provided with a valve 19 that adjusts the amount of rainwater flowing to the watering facility 12. The culture soil layer 13 is made by placing culture soil such as humus soil in a hemp sack or the like and laying it, so that it can be easily replaced. Reference numeral 15 denotes a raw gas inlet provided below the carrier packed layer 14, and reference numeral 16 denotes a processing gas outlet provided above the carrier packed layer 14. 22 is a damper provided in the outlet side duct of the processing gas. By adjusting this, the amount of air flowing to the outlet side duct and the amount of air flowing to the culture soil layer 13 can be changed. Reference numeral 17 denotes a perforated plate for adjusting the flow rate of water falling on the carrier packed layer 14, and reference numeral 18 denotes a perforated plate for adjusting the raw gas so as to uniformly flow through the entire carrier packed layer 14.
[0012]
Next, the operation of this embodiment will be described according to the processing procedure.
[0013]
The raw gas containing malodorous substances and the like enters from 15 and is adjusted so as to flow uniformly over the entire carrier packed layer 14 by 18 air amount adjusting perforated plates, and passes through the carrier packed layer 14 in an upward flow. During this time, malodorous substances and the like are absorbed, adsorbed, and decomposed by inhabiting microorganisms, and later discharged from 16.
[0014]
By closing the outlet duct damper 22, the air treated in the carrier packed layer 14 flows into the culture soil layer 13 and passes through the culture soil layer 13 in an upward flow. During this time, malodorous substances remaining without being treated by the carrier packed layer 14 are absorbed, adsorbed, and decomposed by inhabiting microorganisms, and then discharged to the atmosphere.
[0015]
A certain amount of rainwater adjusted by the flow rate adjusting valve 19 is sprayed from the water spraying facility 12 to the culture soil layer 13 from the rainwater storage tank 11 storing rainwater that has fallen during rainy weather.
[0016]
While water sprinkled on the culture soil layer 13 passes through the culture soil layer 13, nutrients and inhabiting microorganisms in the culture soil flow out and are taken into the water.
[0017]
A certain amount of water containing nutrients and inhabiting microorganisms in the culture soil passes through the water amount adjusting perforated plate 17, falls, and is sprinkled on the carrier packed layer 14.
[0018]
While the sprinkled water passes through the carrier-packed layer 14, washing of salts and products adhering to the carrier and replenishment of water and nutrients necessary for maintaining microbial inhabitants are performed.
[0019]
The water dropped after passing through the carrier packed layer 14 passes through the crushed stone layer 20 and penetrates into the underground 21.
[0020]
When malodorous substances and the like are contained in the water that has penetrated into the underground 21, it is decomposed by microorganisms such as microorganisms in the water and underground soil fungi.
[0021]
As described above, the present invention has been described with reference to a typical example, but the present invention is not limited to this example.For example, instead of rainwater used in the example, water that has penetrated underground is stored, Modifications such as a method of pumping this up and recirculating, or a method of using a culture solution instead of the culture soil can be applied.
[0022]
【The invention's effect】
If removal of malodorous substances and the like contained in the atmosphere and exhaust gas is performed by the biological air purification apparatus using rainwater / cultured soil of the present invention, the following remarkable effects can be obtained.
[0023]
In the present invention, rainwater and snowmelt water are stored, and this water is sprayed onto the carrier packed layer, so that it can be used at low cost and in large quantities. In addition, there is no need to perform management such as maintaining a constant salt concentration or adjusting pH.
[0024]
Further, in the present invention, since water that has taken in nutrients in the culture soil through the culture soil layer is sprinkled on the carrier packed layer, the nutrients can be supplied to the microorganisms in the carrier packed layer, and the activity of the microorganisms The removal efficiency of malodorous substances and the like is increased.
[0025]
In addition to the nutrients in the culture soil, the microorganisms are taken into the water that has passed through the culture soil layer, and it is possible to capture and decompose malodorous substances and the like by the microorganisms, thereby increasing the processing efficiency. .
[0026]
In addition, water that has fallen after passing through the carrier packed bed penetrates underground, but if malodorous substances are contained in the moisture that has penetrated underground, it will be decomposed by microorganisms such as microorganisms in the moisture and underground soil bacteria. In addition, there is a complementary effect in the case where the treatment in the carrier packed layer is insufficient.
[0027]
Moreover, two treatments, the conventional packed tower type biological deodorization method and the soil deodorization method, can be performed simultaneously, and the advantages of both are shared.
[0028]
As described above, it is possible to provide an air purification apparatus that is inexpensive in equipment cost and operation cost and can stably remove odorous substances and the like contained in the atmosphere and exhaust gas with high efficiency.
