脱臭する脱臭方法に関する。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a deodorizing method. In particular, the present invention relates to a deodorizing method for biologically deodorizing odors generated from human waste treatment plants, sewage treatment plants, and various other factories.
アンモニア、硫化水素、メチルメルカプタンおよび硫化
メチル等の悪臭物質を含有する臭気を脱臭材と接触させ
、脱臭材の表面に生息する微生物によって、悪臭物質を
酸化あるいは資化する脱臭方法が知られている。A deodorizing method is known in which odor containing malodorous substances such as ammonia, hydrogen sulfide, methyl mercaptan, and methyl sulfide is brought into contact with a deodorizing material, and the malodorous substances are oxidized or assimilated by microorganisms living on the surface of the deodorizing material. .
脱臭材としては、土壌、コンポスト化汚泥のほか、ビー
ト活性炭、ゼオライト等の担体の微生物を植種したもの
が使用されている。As deodorizing materials, in addition to soil and composted sludge, carriers such as beet activated carbon and zeolite inoculated with microorganisms are used.
この従来法においては、脱臭材の充填層には微生物の活
性を維持するため適時散水を行って、含水率を５０〜８
０ｃｓに保持していた。In this conventional method, the packed bed of deodorizing material is sprinkled with water at appropriate times to maintain the activity of microorganisms, and the moisture content is maintained at 50 to 8.
It was kept at 0cs.
このための散水用水としては、工業用水や井水が用いら
れていた。Industrial water or well water has been used as water for this purpose.
しかしながら、散水用水として工事用水、井水を用いる
方法は次のような問題があった。However, the method of using construction water or well water as watering water has the following problems.
■ 悪臭物質の処理に伴って、層内に硫酸、亜硫酸など
が生成し、層のｐＨが低下する。■ As malodorous substances are treated, sulfuric acid, sulfurous acid, etc. are generated within the layer, and the pH of the layer decreases.
■ 硫化メチルなど難分解性の悪臭成分の除去率が低い
。■ The removal rate of persistent malodorous components such as methyl sulfide is low.
本発明は、以上のような従来法の問題点を解決する簡単
な脱臭方法を提供することを目的とする。An object of the present invention is to provide a simple deodorizing method that solves the problems of the conventional methods as described above.
本発明の脱臭方法は、悪臭物質を分解する微生物が付着

のである。The deodorizing method of the present invention is a method of biologically decomposing and deodorizing malodorous substances by aerating odor through a layer of filler to which microorganisms that decompose malodorous substances are attached, in which biologically treated wastewater is filled. By spraying the filler material onto the filler layer, water is supplied to the filler layer and decomposition products are washed away.
汚水の生物学的処理水としては、通常悪臭は下水処理場

酸素曝気法などが採用されているが、本発明においては
、既設の処理場の処理水を利用すればよい。Biologically treated sewage water is generally used at sewage, human waste, or various sewage treatment plants, as bad odors are usually generated from sewage treatment plants, human waste treatment plants, and other factories, as well as treatment plants for wastewater discharged from those factories. Biologically treated water can be used. Biological treatment of sewage can be carried out depending on the type of sewage, including the standard activated sludge method and its modified methods, oxidation silanditch, sprinkled P bed method, rotating disk method, catalytic oxidation method, fluidized bed method, deep aeration method,
Oxygen aeration methods have been adopted, but in the present invention, treated water from an existing treatment plant may be used.
充填材層への散水量は、充填材の種類、充填密度などに
よるが、一般的に゛は充填材層単位体積当り１日に同体
積の５／１０００〜４０／１０００を目安とする。散水
は、連続でも間欠でもよいが、１日に１〜２回程度、間
欠に散水した方が処理操作が簡単であるので好ましい。The amount of water to be sprinkled on the filler layer depends on the type of filler, packing density, etc., but in general, the standard value is 5/1000 to 40/1000 of the same volume per unit volume of the filler layer per day. Watering may be continuous or intermittent, but it is preferable to sprinkle water intermittently once or twice a day because the treatment operation is simpler.
充填材は、ビート（泥炭）、活性炭、ゼオライト、木材
チック、わら、グラスチック成形物など表面積が大きく
て、微生物が付着するものならば使用できるが、通気抵
抗の少ないものが好ましい。Fillers that have a large surface area and allow microorganisms to adhere to them, such as beets (peat), activated carbon, zeolite, wood tick, straw, and molded glass materials, can be used, but fillers with low ventilation resistance are preferred.
充填材層に微生物を植付けるには、活性汚泥を１０倍程
度に希釈したもの、活性汚泥処理水、河川水を散布すれ
ばよい。In order to inoculate the filler layer with microorganisms, activated sludge diluted approximately 10 times, activated sludge treated water, or river water may be sprayed.
このように、微生物が付着した充填材の層に、悪臭物質

分解される。たとえば硫化水素は硫酸となる。悪臭物質
としてアンモニアが含まれている場合は、その硫酸と・
反応して硫酸アンモニウムとなることもある。In this way, when the odor containing the malodorous substance is passed through the filler layer to which the microorganisms have adhered, the malodorous substance is decomposed by the microorganisms. For example, hydrogen sulfide becomes sulfuric acid. If ammonia is included as a malodorous substance, its sulfuric acid and
It may also react to form ammonium sulfate.
また、アンモニアは硝化細菌の作用により、硝酸や亜硝

充填材層の水分が蒸発し、充填材層の含水率が低下する
ので、散水によって水分を補給し、微生物の活性を高く
維持する。Ammonia can also be converted into nitrate or nitrite by the action of nitrifying bacteria. If these decomposition products or their reaction products accumulate in the filler layer, they will have a negative effect on the activity of microorganisms, so biologically treated waste water is sprayed over the filler layer to wash them away. Also, due to ventilation,
Since the water in the filler layer evaporates and the water content of the filler layer decreases, water is replenished by sprinkling water to maintain high microbial activity.

ている。The present invention will be described in detail below with reference to the drawings. The drawing shows a deodorizing device used in the present invention. 1 is a biological deodorizing tower, and this tower is filled with beet fibers to form a beet layer 2. The odor enters the biological deodorizing tower IK from the gas inlet pipe 3, is decomposed by microorganisms in the beet layer 2, and then passes through the pipe 4.
The deodorized gas will leak out. Biologically treated sewage water is supplied from the pipe 5 and sprinkled through the sprinkler pipe 6 to supply water to the packing material layer, and the decomposition products or reaction products accumulated in the bed are also discharged from the tower through the pipe 7. It is meant to be washed away.

の生物処理水を１日１回４０１３／ｒｒ？−充填材層、
散布して脱臭処理したところ、次表に示す結果を得た。The biological deodorizing tower 1 has an inner diameter of 5007+1111 mm and is filled with beet fibers to a height of 0.5 m. The beet fibers used were those that were sieved through a sieve with a mesh size of s+m to remove short fibers. Two biological deodorization towers are prepared, and they are used to store high-concentration odors from the human waste treatment plant (human waste storage tank, human waste temporary storage tank,
Odors generated from pre-treatment equipment, etc.) are aerated at a space velocity (SO) of 20 hr, respectively, and biologically treated water from a human waste treatment plant is pumped once a day into a 4013/rr?-filling material layer.
When sprayed and deodorized, the results shown in the following table were obtained.
表
この処理を８週間継続したところ、硫化メチルの除去率
は、生物処理水を散布する本発明においては１週間後か
ら９９．９％を維持していたが、井水を用いた場合は９
６％のままで、向上することがなかった。Table: When this treatment was continued for 8 weeks, the removal rate of methyl sulfide was maintained at 99.9% after 1 week in the present invention where biologically treated water was sprayed, but when well water was used, the removal rate of methyl sulfide remained at 99.9%.
It remained at 6% and did not improve.
本発明においては、充填材層に生物処理水を散布するの
で、ｐＨに対しバッファー効果がある。そのため硫酸の
生成によるｐＨ低下が緩和され、微生物の活性が維持さ
れるので、硫化メチルの除去率が高い。生物処理水には
微生物が含まれているほか、窒素、リンの栄養源もある
ので、水分と微生物が補給されると共に、生息する微生
物の活性が維持される。In the present invention, since biologically treated water is sprayed on the filler layer, it has a buffering effect on pH. Therefore, the decrease in pH due to the production of sulfuric acid is alleviated and the activity of microorganisms is maintained, resulting in a high removal rate of methyl sulfide. Biologically treated water contains microorganisms and is also a source of nutrients such as nitrogen and phosphorus, so water and microorganisms are replenished and the activity of the living microorganisms is maintained.
さらに、生物処理水を使用するので、用水を特に必要と
せず、散水後のドレン水は、し尿や下水の処理施設に戻
せばよいので、施設の処理水量を増加させることがない
。Furthermore, since biologically treated water is used, no special water is required, and the drain water after watering can be returned to the human waste and sewage treatment facility, so there is no need to increase the amount of water treated at the facility.
