Reference numeral 1 in FIG. 1 denotes a sewage / sludge treatment device for effectively treating these sewage. The container body 2 into which the sewage is introduced has a substantially cylindrical shape. The container body 2 is made of a material such as stainless steel to prevent corrosion due to the sewage, and has a plurality of legs 4 extending vertically from the base 3. It is erected by
容器体 2の上方には、 汚水を容器体 2内部に導入させるための導入管 5 と、 容器体 2内部で発生するガスや空気やオーバーフロー水を排出さ せる排出管 6が取り付けられている。 容器体 2の下方には、 容器体 2内 部の水を排水させるための排水管 7が設けられている。 この排水管 7に は、 トラップ 7， が形成されており、 排水管 7は トラップ 7， に溜めら れた水によって栓がされているので、 容器体 2内部の空気が、 排水管 7 から外部に流れ出るのを防ぐことができる。 Above the container 2, an inlet pipe 5 for introducing sewage into the container 2 and a discharge pipe 6 for discharging gas, air and overflow water generated inside the container 2 are attached. Below the container 2, a drain pipe 7 for draining water inside the container 2 is provided. A trap 7 is formed in the drain pipe 7, and the drain pipe 7 is trapped in the trap 7. Since the water is plugged with the water, the air inside the container body 2 can be prevented from flowing out of the drain pipe 7 to the outside.
また、 容器体 2の上部には、 水を容器体 2内部に供給させることがで きる散水手段と しての散水管 8が設けられており、 水を容器体 2内部に シャワー状に散水させることができる複数の散水口 9が、 散水管 8に形 成されている。  At the upper part of the container 2, a water sprinkling pipe 8 is provided as a water sprinkling means for supplying water to the inside of the container 2, and the water is sprinkled into the container 2 in a shower. A plurality of water outlets 9 are formed in the water pipes 8.
容器体 2の下部には、 曝気用の空気を容器体 2内部に供給させること ができる、 散気手段と しての散気管 1 0が設けられており、 ブロアーモ 一ター 1 1から供給される圧縮空気を容器体 2内部に噴出させるこ とが できる複数の散気口 1 2が、 散気管 1 0に形成されている。  At the lower part of the container 2, there is provided an air diffuser 10 as an air diffuser capable of supplying air for aeration into the container 2, and is supplied from a blower motor 11. A plurality of air diffusers 12 through which compressed air can be blown into the container body 2 are formed in the air diffuser tube 10.
容器体 2の内部には、 容器体内部で自由に移動させるこ とができる微 生物担持用の担体 1 3が多数投入されており、 これら担体 1 3は、 好気 性微生物の菌床と して使用できるよ うに、 籾殻、 不織布、 スポンジなど の材質で構成されていることが効果的であり、 プラスチック材料等を多 孔質化させたポーラスなども使用させることができる。 単一の材質だけ ではなく、 複数の材質の担体 1 3を混合させて使用するこ ともでき、 好 気性微生物のみならず、 中和剤、 臭気抑制剤等を添加させることもでき る。  A large number of carriers 13 for supporting microorganisms, which can be freely moved inside the container, are loaded into the container 2, and these carriers 13 serve as a bed of aerobic microorganisms. It is effective to use a material such as rice husk, non-woven fabric, sponge, etc., so that it can be used even if it is made of a porous material such as a plastic material. Not only a single material, but also a mixture of carriers 13 of a plurality of materials can be used, and not only aerobic microorganisms but also a neutralizing agent, an odor suppressing agent, and the like can be added.
容器体 2内部の下方には、 仕切体と しての板状に形成されているパン チングメ タル 1 4が設けられている。 このパンチングメタル 1 4は、 多 数の小孔 1 5がステンレスの板に形成された多孔板よ りなり、 この小孔 1 5 の大きさは、 使用される担体 1 3の大きさよ り も小さ く形成されて いるので、 水や空気は容易に通過させることができるが、 担体 1 3は通 過させないよ うになっている。  Below the inside of the container 2, a punching metal 14 formed in a plate shape as a partition is provided. The punched metal 14 is made of a perforated plate having a number of small holes 15 formed in a stainless steel plate, and the size of the small holes 15 is smaller than the size of the carrier 13 used. Since it is well formed, water and air can be easily passed through, but the carrier 13 is not allowed to pass.
容器体 2内部の下方をパンチングメタル 1 4によつて仕切ることで、 担体 1 3を容器体 2内部の定位置に保持させることができるばかりカヽ 担体 1 3が排水管 7から容器体 2の外部に流出することを防ぐことがで きるよ う になつている。 また、 容器体 2内部の担体 1 3の上方もパンチングメタル 1 6 よって 仕切られており、 パンチングメ タル 1 6が設けられていることで、 容器 体 2内部の水がオーバーフローした際に、 担体 1 3が排出管 6から容器 体 2の外部に流出することを防止できるよ う になつている。 By partitioning the inside of the container body 2 with a punching metal 14, the carrier 13 can be held at a fixed position inside the container body 2. To prevent spills. In addition, the upper part of the carrier 13 inside the container body 2 is also partitioned by the punching metal 16, and the punching metal 16 is provided, so that when the water inside the container body 2 overflows, the carrier 1 3 can be prevented from flowing out of the container body 2 from the discharge pipe 6.
略円筒形状をした容器体 2の中心軸には、 シャフ ト 1 7が鉛直方向に 延ぴており、 このシャフ ト 1 7には、 攪拌手段と しての横方向を向いて 固着された複数の攪拌棒 1 8が取り付けられている。 シャフ ト 1 7の下 端は、 容器体 2の下方に設けられている駆動モーター 1 9に直結させら れており、 攪拌棒 1 8は、 図 2に示すよ うにシャフ ト 1 7を中心に四方 に延びて、 シャフ ト 1 7を中心軸と して矢印に示すよ うに回転させるこ とができるよ うになっている。  A shaft 17 extends in the vertical direction on the center axis of the container 2 having a substantially cylindrical shape, and a plurality of shafts 17 are fixed to the shaft 17 in a lateral direction as stirring means. A stir bar 18 is attached. The lower end of the shaft 17 is directly connected to a drive motor 19 provided below the container body 2, and the stirring rod 18 is centered on the shaft 17 as shown in FIG. It extends in all directions and can be rotated about the shaft 17 as a central axis as shown by the arrow.
汚水を処理させる際には、 先ず駆動モーター 1 9を駆動させると、 シ ャフ ト 1 7が回転し、 攪拌手段と しての攪拌棒 1 8が回転させられるの で、 容器体 2内部の多数の担体 1 3を攪拌させることができ、 導入管 5 から汚水を容器体 2内に導入させると、 汚水は攪拌棒 1 8によって担体 1 3 と混合攪拌されながら下方に流されるよ うになつている。  When treating sewage, first, when the drive motor 19 is driven, the shaft 17 rotates, and the stirring rod 18 as a stirring means is rotated. A large number of carriers 13 can be agitated, and when sewage is introduced into the container body 2 from the introduction pipe 5, the sewage flows downward while being mixed and stirred with the carriers 13 by the stirring rod 18. I have.
一旦担体 1 3に付着した水分は、 攪拌されることによって順次他の担 体 1 3に移動もしく はパンチングメタル 1 4を介して下方に流れ落ちよ うになる。 担体 1 3が水中に存在するのではなく 、 担体 1 3が常に濡れ た状態が維持されて攪拌されることによって、 空気が担体 1 3 の表面水 分に頻繁に接触して溶け込むよ うになり、 好気性微生物を常に活性化さ せることができるよ うになる。  The water once attached to the carrier 13 moves to another carrier 13 or flows downward through the punching metal 14 sequentially by being stirred. The carrier 13 is not present in the water, but is stirred while the carrier 13 is constantly kept in a wet state, so that air frequently comes into contact with the surface water of the carrier 13 and dissolves. Aerobic microorganisms can always be activated.
そして、 曝気用空気がブロア一モーター 1 1から供給させられて、 散 気管 1 0を通って、 散気口 1 2 よ り容器体 2の内部に噴出させられ、 パ ンチングメタル 1 4の小孔 1 5を通過し、 多数の担体 1 3の隙間を通り 上昇させられる。 担体 1 3の下方には、 仕切体と してのパンチングメタ ル 1 4が設けられていることで、 散気口 1 2 よ り噴出さられた十分な量 の新鮮な空気を下方から均等に担体 1 3 に接触させられるようになって いる。 Then, aeration air is supplied from the blower motor 11, passes through the air diffuser 10, and is jetted out of the air diffuser 1 2 into the container 2, and the small holes 1 of the punching metal 14 are formed. 5 and can be raised through the gaps between the large number of carriers 13. Under the carrier 13, a punching metal 14 is provided as a partition so that a sufficient amount of fresh air blown out from the air diffuser 12 can be evenly distributed from below. Being able to contact carrier 1 3 I have.
そのため、 常に多量の酸素を担体 1 3内の好気性微生物に与えること ができ、 微生物の働きが活性化させられるので、 汚水中の有機物等の分 解が促進させられ、 汚水を浄化させるこ とができるよ うになる。 容器体 2内部に空気が送り込まれることによって、 有機物のみならず、 その他 の物質等も酸化分解させること もできるよ う になつている。  Therefore, a large amount of oxygen can always be supplied to the aerobic microorganisms in the carrier 13 and the action of the microorganisms is activated, so that the decomposition of organic substances and the like in the sewage is promoted and the sewage is purified. Will be able to do it. By sending air into the container 2, not only organic matter but also other substances can be oxidatively decomposed.
また、 散水管 8 よ り供給させられた水が、 散水口 9からシャワー状に 噴射させられるので、 多量の水が汚水に加わることになり、 汚水の濃度 を薄めることができるばかりか、 多量の水分が微生物に与えられること で、 微生物の増殖が活発になり汚水を浄化させやすく なる。  Further, since the water supplied from the water sprinkling pipe 8 is sprayed from the water sprinkling port 9 in a shower shape, a large amount of water is added to the sewage, so that not only the concentration of the sewage can be reduced, but also a large amount. When water is given to the microorganisms, the growth of the microorganisms is activated and the wastewater is easily purified.
¾ 拌手段である攪拌棒 1 8によって、 担体 1 3 と空気と水が強制的に 混合攪拌されるので、 多量の空気を担体 1 3に触れさせることができ、 多量の酸素が好気性微生物に与えられて活性化させられるので、 微生物 が汚水を浄化させる能力を向上させることができるよ うになる。 そのた め汚水中の有機物等は、 微生物の働きによって水と二酸化炭素 ( C O 2 ) に分解され、 実質的にほぼ消滅させられるよ うになつている。 攪拌 The carrier 13 and the air and water are forcibly mixed and stirred by the stirring rod 18 as a stirring means, so that a large amount of air can be brought into contact with the carrier 13 and a large amount of oxygen is supplied to the aerobic microorganisms. Given and activated, the ability of microorganisms to purify sewage can be improved. For this reason, organic matter in sewage is decomposed into water and carbon dioxide (CO 2 ) by the action of microorganisms, and is almost completely eliminated.
汚水の浄化能力を向上させることで、 短時間で汚水を処理できるよ う になり、 汚水を容器体 2上方に設けた導入管 5から導入させながら、 浄 化させた水を容器体 2下方に設けた排水管 7から排水させることで、 汚 水を連続的に浄化させるこ とができるよ うになる。  By improving the purification capacity of sewage, sewage can be treated in a short time.While sewage is introduced from the introduction pipe 5 provided above the container body 2, the purified water is supplied to the lower part of the container body 2. By draining water from the provided drain pipe 7, sewage can be continuously purified.
容器体 2内部で発生するガスや散気口 1 2から噴出させた空気などの 排気は、容器体 2の上部に設けられている排出管 6 よ り排出させられる。 この排出管 6は、 途中で上下に分岐されており、 ガスなどの排気は上方 に向かって排出させ、 容器体 2内の水がオーバーフローした際には、 溢 れ出た水を下方に分流させるこ とができるよ う になっている。 オーバー フローした水は、 一時的にオーバーフロータンクに溜めることで、 再ぴ 導入管 5から容器体 2内へ導入させることもできる。  Exhaust such as gas generated inside the container body 2 and air ejected from the air diffuser port 12 is discharged through a discharge pipe 6 provided at an upper part of the container body 2. The discharge pipe 6 is branched upward and downward on the way, and exhaust gas and the like are discharged upward, and when the water in the container body 2 overflows, the overflow water is diverted downward. You can do this. The overflowed water can also be introduced into the container 2 from the regeneration introduction pipe 5 by temporarily storing the water in an overflow tank.
また、 排気をプロァーモーター 1 1 に流入ざせることもでき、 容器体 2内部で発生する臭気などを再び容器体 2内部に流入させて、 臭気を大 気中に放出させないよ うにもできる。 汚水 · 汚泥処理装置 1内で循環さ せることで、 臭気を微生物に分解させることができ、 汚水 . 汚泥処理装 置 1 .を脱臭装置と しても使用できる。 そのため、 排出管 6から排出され る排気中には、 ほとんど臭気が含まれなく なるので、 汚水 · 汚泥処理装 置 1周辺の環境が悪化せずにすむよ う になる。 Exhaust gas can also flow into the promotor 11 Odors and the like generated inside 2 can be re-introduced into the container 2 so that the odor is not released into the atmosphere. By circulating in the sewage / sludge treatment device 1, odors can be decomposed into microorganisms, and the sewage / sludge treatment device 1 can be used as a deodorization device. Therefore, the exhaust gas discharged from the discharge pipe 6 hardly contains an odor, so that the environment around the sewage / sludge treatment device 1 does not deteriorate.
複数台の汚水 · 汚泥処理装置 1 を直列または並列につないで使用させ ること もでき、 数台の汚水 · 汚泥処理装置 1 を直列につないだ場合、 そ れぞれ異なった微生物を使用させることで、 汚水の状態に適した装置の 構成が可能であり、 並列につないだ場合には、 汚水の処理速度を向上さ せることができるよ う になる。  Multiple sewage and sludge treatment equipment 1 can be connected in series or in parallel, and when several sewage and sludge treatment equipment 1 are connected in series, different microorganisms can be used respectively. Therefore, it is possible to configure a device suitable for the state of sewage, and when connected in parallel, it is possible to improve the processing speed of sewage.
