【0015】
【発明の実施の形態】
以下、本発明を一実施形態に基づいて説明する。
【0016】
図1には、一実施形態に係る種充填材馴養装置の概略構成を示す。図1に示すように、種充填材馴養装置10は、種充填材を馴養するための充填塔11を具備し、充填塔11内のグリッド12上には充填材13が充填されている。充填塔11には、途中にファン14が介装された循環パイプ15が設けられており、充填塔11内の雰囲気ガスを循環できるようになっている。また、充填塔11の充填材13の上方には、散水ノズル16が設けられている。散水ノズル16には給水管17を介してポンプ18及び貯水槽19が連結さており、貯水槽19内に湛えられた水がポンプ18により散水ノズル16から充填材13に散水されるようになっている。また、散水されて底部に溜まった水は循環用配管20を介して貯水槽19へ戻されるようになっている。なお、排水用配管21は別途設けられており、また、充填塔11の雰囲気ガスを排気するための排気用配管22には活性炭吸着塔23が介装されている。
【0017】
以上の構成により、充填塔11に充填材13を充填し、充填塔11に直接、又は貯水槽19を介して臭気を供給し、散水ノズル16から散水すると共に臭気を含んだ雰囲気ガスを循環することにより、充填材13に付着した微生物を馴養することができる。
【0018】
ここで、充填塔11のグリッド12上に充填する充填材13の種類は特に限定されず、生物脱臭装置で用いることができるものを用いればよい。具体的には、天然繊維状有機物質(ピート)、又は、樹脂製もしくはセラミックス製の人工充填材や、特開平7−303833号公報に開示されるような吸水性合成繊維の嵩高成形体を用いることができる。また、充填材の形状としてはプレート状や塊状のものを用いることができる。なお、充填材13の一部として、他の生物脱臭装置等で使用した種充填材を添加してもよい。
【0019】
充填材13に生物脱臭の微生物を馴養するためには、脱臭目的の臭気成分を充填塔11内に添加する。臭気成分は、充填塔11に直接添加してもよいし、循環パイプ15を介して添加してもよいし、散水ノズル16から散水される水を介して添加してもよい。
【0020】
臭気成分として、硫化水素(HS)、メチルメルカプタン(MM)、硫化メチル(DMS)、二硫化メチル(DMDS)などを挙げることができ、これらの成分を充填塔11へ直接添加し、循環パイプ15及びファン14を介して循環させてもよいし、これらの臭気成分の原料となる材料を貯水槽19へ添加して散水ノズル16から散水するようにしてもよい。例えば、メチルメルカプタンの場合には、メタンチオールナトリウム溶液を貯水槽19へ添加すればよいし、また、硫化水素の原料となる硫化ナトリウムを貯水槽19に添加してもよい。
【0021】
このような臭気成分を添加した雰囲気下で、雰囲気ガスを循環することにより、臭気ガス成分の有効利用を図ると共に、馴養の効率を高めることができるという利点がある。
【0022】
また、充填材13に微生物を馴養するために、散水ノズル16を介して充填材13に適当な水分を供給する。この散水量は特に限定されず、微生物の馴養に好適な条件となるように行えばよく、間欠的に行っても連続的に行ってもよい。
【0023】
なお、充填塔11内の温度は特に限定されないが、微生物の馴養に好適な温度にするのが望ましく、寒冷期においては、加温するようにするのが好ましい。加温方法は、充填塔11にヒータ等を設けてもよいが、貯水槽19の水を加温して散水するようにしてもよい。また、循環パイプ15を介して温風を循環するようにしてもよい。
【0024】
充填材13に散水される水は、下水二次処理水または下水三次処理水が好適に使用できる。これは、下水二次処理水や下水三次処理水には、臭気成分を分解するための微生物が予め存在するとともに、微生物に有害な塩素などの殺菌剤がほとんど含有されないためである。
【0025】
また、種充填材馴養装置10を立ち上げるときには、排水の活性汚泥処理で使用される汚泥を予め充填材13に散布することが好ましい。具体的には、貯水槽19に汚泥濃度が数十から数千mg/L程度となるよう活性汚泥を添加し、散水時に汚泥を充填材13に散布できるようにする。
【0026】
以上説明した種充填材馴養装置10において、馴養を完了して種充填材とした後は、雰囲気ガスを排気用配管22より排気して活性炭吸着塔23で脱臭して排気し、また、散水された水を排水用配管21を介して排水するが、pHが低い場合は貯水槽19で中和処理した後に排水する。
【0027】
図2には、生物脱臭装置30の一例を示すが、上述した種充填材馴養装置10が併設されていてもよいし、別途設けられていてもよい。
【0028】
図2に示すように、処理塔31を具備し、処理塔31のグリッド32上には充填材33が充填されている。処理塔31の充填材33の上方には、散水ノズル34が設けられている。散水ノズル34には給水管35を介してポンプ36及び貯水槽37が連結されており、貯水槽37内に湛えられた水がポンプ36により散水ノズル34から充填材33に散水されるようになっている。また、散水されて底部に溜まった水は排水管38を介して排水されるようになっている。
【0029】
このような処理塔31の下部にはファン39が介装された導入管40が接続されており、被処理ガスが導入されるようになっている。一方、処理塔31の上部には排気管41が連結されており、処理ガスが排気されるようになっている。
【0030】
このような生物脱臭装置30では、充填材33の少なくとも一部として、種充填材馴養装置10で馴養した種充填材を最初から用いる以外は、従来の生物脱臭装置と同様である。すなわち、被処理ガスを導入しながら、散水ノズル34を介して適当な散水を行う。しかしながら、上述したような種充填材を用いることにより、設置後、短期間で脱臭環境を整えることができ、処理ガスに悪臭が含まれる状態を極めて短期間に低減することができる。
【0031】
なお、種充填材の添加量は、例えば、充填材33の全体の1/10〜1/2程度であるが、全量を種充填材としてもよい。
【0032】
(実施例)
図1に示す種充填材馴養装置10を用い、9mの容量の充填塔11に、セラミックス製の粒径10mmの塊状人工充填材を1段充填し、種充填材馴養装置10内を循環する雰囲気ガスの硫化水素濃度が50cm/mとなるよう充填塔11へ硫化水素ガスを添加するとともに、充填材13に散水する水のメチルメルカプタン濃度が20mg/Lとなるよう貯水槽19へメタンチオールナトリウムを添加し、4m/分の風量で雰囲気ガスを循環するとともに、30分おきに0.25m/分で2分間散水し、臭気が除去される度にこの操作を繰り返し行い、30日間連続して運転することにより、微生物を馴養し、微生物を担持し種充填材を得た。なお、連続運転中、貯水槽19内の貯留水は温度30〜40度になるよう貯水槽19に設置したヒータで保温した。
【0033】
この充填材13を新規充填材に対して1/4量分混入し、カラム試験を行った。15分間隔で20秒間、150mL/分で散水しながら、臭気ガスとして硫化水素を3cm/m導入したが、1日後には処理ガス中の硫化水素濃度は0.3cm/m以下(除去率90%以上)となった。
【0034】
(比較例)
この種充填材を用いない以外は、図2に示す生物脱臭装置30を実施例と同様に運転したところ、硫化水素の除去率が90%以上となるまでに10日を要した。
【0035】
【発明の効果】
以上説明したように、本発明によると、生物脱臭装置の充填材の一部として別途設けた種充填材馴養装置で馴養した種充填材を用いることにより、短期間で脱臭環境が整い、生物脱臭装置を迅速に立ち上げることができるという効果を奏する。

[0015]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, the present invention will be described based on an embodiment.
[0016]
In FIG. 1, schematic structure of the seed filler habituation apparatus which concerns on one Embodiment is shown. As shown in FIG. 1, the seed filler acclimation apparatus 10 includes a packed tower 11 for acclimating the seed filler, and a grid 13 in the packed tower 11 is filled with a filler 13. The packed tower 11 is provided with a circulation pipe 15 in which a fan 14 is interposed, so that the atmospheric gas in the packed tower 11 can be circulated. A watering nozzle 16 is provided above the filler 13 in the packed tower 11. The water spray nozzle 16 is connected with a pump 18 and a water storage tank 19 through a water supply pipe 17, and water stored in the water storage tank 19 is sprayed from the water spray nozzle 16 to the filler 13. Yes. Further, the water which has been sprinkled and accumulated at the bottom is returned to the water storage tank 19 via the circulation pipe 20. The drainage pipe 21 is provided separately, and the activated carbon adsorption tower 23 is interposed in the exhaust pipe 22 for exhausting the atmospheric gas in the packed tower 11.
[0017]
With the above configuration, the packed column 11 is filled with the filler 13, the odor is supplied to the packed column 11 directly or through the water storage tank 19, and the atmosphere gas containing the odor is circulated while watering from the watering nozzle 16. Thereby, the microorganisms adhering to the filler 13 can be acclimatized.
[0018]
Here, the kind of the filler 13 to be packed on the grid 12 of the packed tower 11 is not particularly limited, and a material that can be used in a biological deodorization apparatus may be used. Specifically, a natural fibrous organic substance (peet), an artificial filler made of resin or ceramics, or a bulky molded body of water-absorbing synthetic fiber as disclosed in JP-A-7-303833 is used. be able to. Moreover, as a shape of a filler, a plate shape or a lump shape can be used. In addition, you may add the seed filler used with the other biological deodorizing apparatus etc. as a part of filler 13.
[0019]
In order to acclimate the biodeodorizing microorganisms to the packing material 13, an odor component for the purpose of deodorization is added to the packed tower 11. The odor component may be added directly to the packed tower 11, may be added via the circulation pipe 15, or may be added via water sprayed from the water spray nozzle 16.
[0020]
Examples of odor components include hydrogen sulfide (H 2 S), methyl mercaptan (MM), methyl sulfide (DMS), and methyl disulfide (DMDS). These components are directly added to the packed column 11 for circulation. You may make it circulate through the pipe 15 and the fan 14, and may add the material used as the raw material of these odor components to the water storage tank 19, and may sprinkle it from the watering nozzle 16. FIG. For example, in the case of methyl mercaptan, a sodium methanethiol solution may be added to the water storage tank 19, or sodium sulfide as a raw material for hydrogen sulfide may be added to the water storage tank 19.
[0021]
By circulating the atmospheric gas in an atmosphere to which such an odor component is added, there is an advantage that the odor gas component can be effectively used and the efficiency of adaptation can be increased.
[0022]
Further, in order to acclimate the microorganisms to the filler 13, appropriate moisture is supplied to the filler 13 through the watering nozzle 16. The amount of sprinkling is not particularly limited, and may be performed so as to be a condition suitable for habitation of microorganisms, and may be performed intermittently or continuously.
[0023]
Although the temperature in the packed tower 11 is not particularly limited, it is desirable that the temperature be suitable for acclimatization of microorganisms, and it is preferable to heat in the cold season. As the heating method, a heater or the like may be provided in the packed tower 11, but the water in the water storage tank 19 may be heated and sprinkled. Further, the hot air may be circulated through the circulation pipe 15.
[0024]
Sewage secondary treated water or sewage tertiary treated water can be suitably used as the water sprayed on the filler 13. This is because the sewage secondary treated water and the sewage tertiary treated water have microorganisms for decomposing odor components in advance and hardly contain bactericides such as chlorine harmful to the microorganisms.
[0025]
Moreover, when starting up the seed filler habituation apparatus 10, it is preferable to spread the sludge used in the activated sludge treatment of the waste water on the filler 13 in advance. Specifically, activated sludge is added to the water storage tank 19 so that the sludge concentration is about several tens to several thousand mg / L so that the sludge can be sprayed on the filler 13 during watering.
[0026]
In the seed filler acclimatization apparatus 10 described above, after the acclimatization is completed and the seed filler is used, the atmospheric gas is exhausted from the exhaust pipe 22, deodorized and exhausted by the activated carbon adsorption tower 23, and water is sprinkled. However, if the pH is low, the water is neutralized in the water storage tank 19 and then drained.
[0027]
Although an example of the biological deodorizing apparatus 30 is shown in FIG. 2, the seed filler acclimatization apparatus 10 mentioned above may be provided side by side, or may be provided separately.
[0028]
As shown in FIG. 2, a treatment tower 31 is provided, and a filler 33 is filled on a grid 32 of the treatment tower 31. A watering nozzle 34 is provided above the filler 33 of the processing tower 31. The water spray nozzle 34 is connected to a pump 36 and a water storage tank 37 through a water supply pipe 35, and water stored in the water storage tank 37 is sprayed from the water spray nozzle 34 to the filler 33. ing. Further, the water that has been sprinkled and accumulated at the bottom is drained through a drain pipe 38.
[0029]
An inlet pipe 40 having a fan 39 interposed is connected to the lower part of the processing tower 31 so that a gas to be processed is introduced. On the other hand, an exhaust pipe 41 is connected to the upper portion of the processing tower 31 so that the processing gas is exhausted.
[0030]
Such a biological deodorization apparatus 30 is the same as the conventional biological deodorization apparatus except that the seed filler conditioned by the seed filler acclimation apparatus 10 is used from the beginning as at least a part of the filler 33. That is, appropriate watering is performed through the watering nozzle 34 while introducing the gas to be treated. However, by using the seed filler as described above, a deodorizing environment can be prepared in a short period of time after installation, and the state in which the processing gas contains malodor can be reduced in a very short time.
[0031]
The added amount of the seed filler is, for example, about 1/10 to 1/2 of the entire filler 33, but the entire amount may be used as the seed filler.
[0032]
(Example)
Using the seed filler acclimatization apparatus 10 shown in FIG. 1, the packed tower 11 having a capacity of 9 m 3 is filled with one stage of ceramic artificial bulk material having a particle diameter of 10 mm and circulated in the seed filler acclimatization apparatus 10. Hydrogen sulfide gas is added to the packed column 11 so that the hydrogen sulfide concentration of the atmospheric gas is 50 cm 3 / m 3, and methane is added to the water tank 19 so that the methyl mercaptan concentration of water sprayed to the filler 13 is 20 mg / L. It was added thiol sodium, with circulating atmospheric gas in air volume of 4m 3 / min, and watering 2 minutes every 30 minutes at 0.25 m 3 / min, repeated this operation every time the odor is removed, 30 By operating continuously for days, the microorganisms were acclimatized, and the microorganisms were supported and seed fillers were obtained. During continuous operation, the water stored in the water tank 19 was kept warm by a heater installed in the water tank 19 so that the temperature was 30 to 40 degrees.
[0033]
A quarter amount of this filler 13 was mixed with the new filler for a column test. Hydrogen sulfide was introduced at 3 cm 3 / m 3 as an odor gas while sprinkling water at 150 mL / min for 20 seconds at 15-minute intervals, but the concentration of hydrogen sulfide in the treated gas was 0.3 cm 3 / m 3 or less after 1 day. (Removal rate 90% or more).
[0034]
(Comparative example)
Except not using this seed filler, the biological deodorization apparatus 30 shown in FIG. 2 was operated in the same manner as in the example. As a result, 10 days were required until the hydrogen sulfide removal rate reached 90% or more.
[0035]
【The invention's effect】
As described above, according to the present invention, the use of the seed filler conditioned by the seed filler cultivating apparatus separately provided as a part of the filler of the biological deodorizing apparatus provides a deodorizing environment in a short period of time, and biological deodorization. There is an effect that the apparatus can be started up quickly.
