Description

本発明は、工場排水や下水等の水処理で処理水に含まれる化学物質を除去するのに使用される活性炭吸着装置に関する。   The present invention relates to an activated carbon adsorbing device used for removing chemical substances contained in treated water in water treatment such as factory waste water and sewage.

活性炭吸着装置は、従来から工場排水処理や下水処理などにおける後段の処理で数多く使用されているが、粒状活性炭を収容した吸着槽内に原水に伴ってＳＳ（懸濁物質）が流入してくると、ＳＳによる活性炭吸着層の目詰まりやＳＳの固化により、流入水の流れで流動する活性炭が流動しなくなり、吸着層内での原水の流れにショートパスを起こして、活性炭の吸着性能が十分に発揮されなくなる。また活性炭吸着層内に堆積したＳＳが腐敗することにより、吸着層を通過した処理水の水質悪化を招くことがある。   Conventionally, activated carbon adsorption devices have been used in many subsequent processes in factory wastewater treatment, sewage treatment, etc., but SS (suspended material) flows into the adsorption tank containing granular activated carbon along with the raw water. Then, due to clogging of the activated carbon adsorption layer by SS and solidification of SS, activated carbon flowing due to the flow of inflow water will not flow, causing a short path in the flow of raw water in the adsorption layer and sufficient adsorption performance of activated carbon Will not be demonstrated. In addition, the SS deposited in the activated carbon adsorption layer may be spoiled to cause deterioration of the quality of treated water that has passed through the adsorption layer.

そこで、吸着性能を発揮させるための中間洗浄として、使用の途中で、吸着槽に洗浄水（清水または原水）を通水しながら活性炭吸着層の活性炭全体を撹拌、混合して、ＳＳを除去する洗浄を行っているが、十分な撹拌、混合が行われないために、活性炭全体を有効に洗浄することができない。   Therefore, as an intermediate cleaning for exerting the adsorption performance, the activated carbon in the activated carbon adsorption layer is stirred and mixed while passing washing water (fresh water or raw water) through the adsorption tank in the middle of use to remove SS. Although the washing is performed, the entire activated carbon cannot be washed effectively because sufficient stirring and mixing are not performed.

また新炭の活性炭を使用する際にも、新炭に含まれる微粉末炭や造粒時の油脂分を洗浄水で洗浄して除去する必要があるが、吸着槽に装入前に新炭を手作業で洗浄するのが現状であった。   In addition, when using activated charcoal of new charcoal, it is necessary to wash and remove the fine powder charcoal contained in the new charcoal and the fats and oils at the time of granulation with washing water. It was the present situation that was washed manually.

さらに、化学物質の吸着により活性炭が破過に達した際、破過に至った活性炭を廃炭として吸着槽外に取り出す必要がある。流動層式および移動層式の吸着装置では、吸着槽の下部等のバルブなどを開ければ、自動的に活性炭が抜ける構造になってはいるが、実際は水が先に抜けてしまい、上部からホースなどで水をかけて流しながら搬出することを要している。固定床式の吸着装置では、吸着槽のマンホールから人力で廃炭を搬出しなければならない。   Furthermore, when activated carbon reaches breakthrough due to adsorption of chemical substances, it is necessary to take out the activated carbon that has broken through to the outside of the adsorption tank as waste coal. In the fluidized bed type and moving bed type adsorption devices, activated carbon is automatically removed by opening a valve at the bottom of the adsorption tank, etc., but in reality, water will first escape and the hose from the top. It is necessary to carry it out with water. In the fixed bed type adsorber, waste coal must be carried out manually from the manhole in the adsorption tank.

なお、活性炭の中間洗浄として、原水の供給停止後、吸着槽の下部から原水通水方向と逆方向に洗浄用の空気を導入し、吸着槽内を空気の泡により流動化して撹拌し、活性炭に付着しているＳＳを洗浄、除去し、ついで吸着槽の下部から空気に代えて洗浄水を通水して、流動化しているＳＳを脱離して活性炭上方に洗い流し、吸着槽の上部の排出管から外部に排出する活性炭吸着装置が知られている（例えば、特許文献１参照）。
特開平６−２３３９７８号公報 As intermediate cleaning of activated carbon, after the supply of raw water is stopped, cleaning air is introduced from the lower part of the adsorption tank in the direction opposite to the direction of raw water flow, and the inside of the adsorption tank is fluidized by air bubbles and stirred. The SS adhering to the catalyst is washed and removed, and then the washing water is passed through from the lower part of the adsorption tank, and the fluidized SS is desorbed and washed above the activated carbon, and the upper part of the adsorption tank is discharged. An activated carbon adsorption device that discharges to the outside from a pipe is known (for example, see Patent Document 1).
JP-A-6-233978

上記特許文献の吸着装置では、空気による流動化で活性炭吸着層を撹拌するので撹拌力が弱く、またその撹拌も洗浄水を通水して混合することを行っていないので、活性炭の洗浄力が弱く、活性炭全体を有効に洗浄してＳＳを除去することができない。また該特許文献は、吸着槽からの破過に至った廃炭の抜き出しや新炭使用時の洗浄については何ら記載がない。   In the adsorption device of the above-mentioned patent document, the activated carbon adsorption layer is agitated by fluidization with air, so the agitation force is weak, and the agitation is not performed by passing washing water and mixing. It is weak and cannot effectively wash the entire activated carbon to remove SS. Moreover, this patent document does not describe anything about extraction of waste coal that has led to breakthrough from the adsorption tank or cleaning when using new coal.

本発明は、上記の現状に鑑み、吸着槽内の活性炭吸着層を十分に洗浄水（清水または原水）と撹拌、混合して、活性炭に付着したＳＳを有効に洗浄、洗浄し、吸着槽外に排出することができ、また吸着槽からの廃炭の抜き出しと新炭使用時の洗浄も容易に実施することを可能とした活性炭吸着装置を提供することである。   In view of the above situation, the present invention effectively stirs and mixes the activated carbon adsorption layer in the adsorption tank with cleaning water (fresh water or raw water) to effectively wash and wash the SS adhering to the activated carbon. And an activated carbon adsorbing device that can easily remove waste coal from the adsorption tank and clean it when new coal is used.

本実施形態の活性炭吸着装置１の機械的構成は以上の通りである。本装置１を運転して原水を吸着処理するには、図２に示すように、吸着槽２に原水供給管５から原水４を所定の運転水位まで供給し、その水位を維持させた状態で原水４の供給を続け、活性炭吸着層３を１０〜６０分程度かけて流下させ活性炭と接触させる。これにより、原水に含まれている化学物質が活性炭に吸着され、原水の臭気や色等も除去される。このようにしてきれいに処理された処理水は、吸着層３の下部から集水箱６の各集水室６ｂに上面の集水材（ストレーナ）６ａを通って集められ、ついで処理水は吸着槽２の水圧によって各集水室６ｂの上部から各集水管１９ａを通って共通集水管１９Ａに流れ、共通集水管１９Ａから集水本管に放流されて、吸着槽２外に取り出される。   The mechanical configuration of the activated carbon adsorption device 1 of the present embodiment is as described above. In order to operate the apparatus 1 to adsorb raw water, as shown in FIG. 2, the raw water 4 is supplied to the adsorption tank 2 from the raw water supply pipe 5 to a predetermined operating water level, and the water level is maintained. The raw water 4 is continuously supplied, and the activated carbon adsorbing layer 3 is allowed to flow down over about 10 to 60 minutes to contact the activated carbon. Thereby, the chemical substance contained in the raw water is adsorbed by the activated carbon, and the odor and color of the raw water are removed. The treated water thus cleaned is collected from the lower part of the adsorbing layer 3 into each collecting chamber 6b of the collecting box 6 through the upper water collecting material (strainer) 6a.

このような原水の処理を続けると、原水中に混入しているＳＳ（懸濁物質）により、活性炭吸着層３が目詰まりを起こし、原水の流れで流動する活性炭が流動しなくなり、吸着層３内での原水の流れにショートパスを起こして、活性炭の吸着性能が有効に利用されなくなる。このため、使用の途中で、半日〜５日に１回程度、活性炭吸着層３を中間的に洗浄する。   If such raw water treatment is continued, the activated carbon adsorption layer 3 is clogged by SS (suspension material) mixed in the raw water, and the activated carbon flowing in the flow of raw water does not flow, and the adsorption layer 3 This causes a short path in the raw water flow and the activated carbon adsorption performance is not used effectively. For this reason, in the middle of use, the activated carbon adsorption layer 3 is washed intermediately about once every half day to 5 days.

まず、集水箱６周りのバルブを全て閉じる。そして図３に示すように、吸着槽２に洗浄水として清水供給管９から清水または原水供給管５から原水（水処理の後段処理の原水は洗浄水として使用することができる）を供給し、ブロア１３を作動させて空気吹き込み管１４からエアリフトポンプ１２に空気を吹き込み、洗浄水供給下にエアリフトポンプ１２を運転する。エアリフトポンプ１２への空気の吹込みにより、エアリフトポンプ１２内の上方への空気の流れに随伴して下端の吸込み口１２ａから活性炭吸着層３の活性炭と水とが吸込まれ、エアリフトポンプ１２内を流れる間に水との撹拌混合により活性炭が洗浄されながら上端の吐出し口１２ｂに至り、原水供給部Ａ側に吐出される。この洗浄によって活性炭からＳＳなどの付着分が除去される。   First, all the valves around the water collection box 6 are closed. And as shown in FIG. 3, the raw water (raw water of the post-process of water treatment can be used as washing water) is supplied to the adsorption tank 2 from the fresh water supply pipe 9 as the washing water or from the raw water supply pipe 5. The blower 13 is operated to blow air from the air blowing pipe 14 to the air lift pump 12, and the air lift pump 12 is operated under the supply of cleaning water. By blowing air into the air lift pump 12, the activated carbon and water of the activated carbon adsorption layer 3 are sucked from the suction port 12a at the lower end along with the upward air flow in the air lift pump 12, and the inside of the air lift pump 12 is While flowing, the activated carbon is cleaned by stirring and mixing with water, reaches the discharge port 12b at the upper end, and is discharged to the raw water supply unit A side. This washing removes the deposits such as SS from the activated carbon.

上記の活性炭から除去された付着分は、水の流れと共に仕切り板７の小孔８を通る経路と仕切り板７の下側を回る経路で原水供給部Ａ側から流出して、洗浄水排出部Ｂ側に移行する。ついで排水トラフ１７の上端の切欠き１７ｃを水の流れと共に越流し、洗浄水排水管１６を経て吸着槽２外に排出される。一方、吐出された活性炭は、仕切り板７によって原水供給部Ａ側から洗浄水排水部Ｂ側に入るのを阻止され、比重により沈降する。洗浄水排出部Ｂ側の下方から舞い上がった活性炭は、排水トラフ１７の上端で阻止され、比重により沈降する。この中間洗浄を１０分〜６０分程度行う。   The adhering matter removed from the activated carbon flows out from the raw water supply part A side along the route passing through the small holes 8 of the partition plate 7 and the lower side of the partition plate 7 together with the flow of water, and the washing water discharge unit Move to B side. Next, the notch 17 c at the upper end of the drainage trough 17 overflows with the flow of water and is discharged out of the adsorption tank 2 through the washing water drainage pipe 16. On the other hand, the discharged activated carbon is blocked by the partition plate 7 from entering the washing water drainage section B side from the raw water supply section A side, and settles due to the specific gravity. Activated carbon that has risen from the lower side of the washing water discharge part B is blocked by the upper end of the drainage trough 17 and settles down due to the specific gravity. This intermediate cleaning is performed for about 10 to 60 minutes.

このように中間洗浄で、吸着槽２への洗浄水の供給下に、エアリフトポンプ１２で活性炭吸着層３から活性炭と水を吸い上げて撹拌混合するので、吸着層３の活性炭全体を十分に洗浄して、活性炭に付着したＳＳを除去し、吸着槽２外に排出することができる。したがって、吸着層全体の活性炭の吸着性能を有効に発揮させることができる。   As described above, since the activated carbon and water are sucked up and mixed from the activated carbon adsorption layer 3 by the air lift pump 12 while supplying the washing water to the adsorption tank 2 in the intermediate washing, the entire activated carbon of the adsorption layer 3 is sufficiently washed. Thus, SS attached to the activated carbon can be removed and discharged out of the adsorption tank 2. Therefore, the adsorption performance of activated carbon in the entire adsorption layer can be effectively exhibited.

その際、集水箱６の一方の集水室６ｂの集水管１９ａの開閉弁１９ａ１と、他方の集水室６ｂの戻し管１９ｂの開閉弁１９ｂ１とを開き、集水箱６からの配管の他の開閉弁を全て閉じ、その状態で逆洗循環ポンプ２１を作動する。これによって、一方の集水室６ｂの上部からの水を集水管１９ａおよび戻し管１９ｂを通って他方の集水室６ｂの下部に圧送し、他方の集水室６ｂの集水材６ａに付着しているＳＳを逆洗して除去するようにすることが好ましい。開く開閉弁を、一方の集水室６ｂの戻し管１９ｂの開閉弁１９ｂ１と、他方の集水室６ｂの集水管１９ａの開閉弁１９ａ１とに変えて、同様な集水材６ａの逆洗を行う。これを交互に繰返す。これにより、活性炭吸着層３内のＳＳを含め、吸着槽２内のＳＳを排出する効果が向上する。   At that time, the open / close valve 19a1 of the water collecting pipe 19a of one water collecting chamber 6b of the water collecting box 6 and the open / close valve 19b1 of the return pipe 19b of the other water collecting chamber 6b are opened, and the other pipes from the water collecting box 6 are opened. All the on-off valves are closed, and the backwash circulation pump 21 is operated in this state. Thereby, the water from the upper part of one water collection chamber 6b is pumped to the lower part of the other water collection chamber 6b through the water collection pipe 19a and the return pipe 19b, and adheres to the water collection material 6a of the other water collection chamber 6b. It is preferable to remove the SS being backwashed. The opening / closing valve to be opened is changed to the opening / closing valve 19b1 of the return pipe 19b of one water collecting chamber 6b and the opening / closing valve 19a1 of the water collecting pipe 19a of the other water collecting chamber 6b, and the same water-collecting material 6a is backwashed. Do. This is repeated alternately. Thereby, the effect which discharges SS in adsorption tank 2 including SS in activated carbon adsorption layer 3 improves.

その後、使用が進んで活性炭が化学物質の吸着により破過に達したとき、活性炭を廃炭として吸着槽２から抜き出す。そのために、図４に示すように、切替え弁１５ａにより廃炭抜き取り管１５を開に切替えると共に、吸着槽２内に循環水として清水供給管９から清水または原水供給管５から原水を供給し、該清水の供給下にエアリフトポンプ１２を運転して、下端の吸込み口１２ａから吸着層３の廃炭と水とを吸込む。吸込まれた廃炭と水とは、エアリフトポンプ１２の廃炭抜き取り管１５の接続部で該管１５に流れ込み、管１５を通って吸着槽２外に排出される。吸込まれた水の一部はエアリフトポンプ１２の上端に達し、原水供給部Ａ側に吐出される。このように吸着槽２内に水を供給しながらエアリフトポンプ１２で廃炭を抜き出すので、廃炭を吸着槽２内に残すことなく完全に抜き取ることができる。   Thereafter, when the use proceeds and the activated carbon reaches breakthrough due to the adsorption of chemical substances, the activated carbon is extracted from the adsorption tank 2 as waste coal. For that purpose, as shown in FIG. 4, the waste coal extraction pipe 15 is switched to open by the switching valve 15 a, and fresh water or raw water supply pipe 5 is supplied as fresh water from the fresh water supply pipe 9 into the adsorption tank 2, The air lift pump 12 is operated under the supply of the fresh water, and the waste coal and water of the adsorption layer 3 are sucked from the suction port 12a at the lower end. The sucked waste coal and water flow into the pipe 15 at the connecting portion of the waste coal extraction pipe 15 of the air lift pump 12 and are discharged out of the adsorption tank 2 through the pipe 15. Part of the sucked water reaches the upper end of the air lift pump 12 and is discharged to the raw water supply unit A side. As described above, the waste coal is extracted by the air lift pump 12 while supplying water into the adsorption tank 2, so that the waste coal can be completely extracted without leaving the adsorption tank 2.

吸着槽２に新規に新炭の活性炭を装入して使用する新炭使用時は、つぎのようにする。先ず、図５に示すように、洗浄水として清水供給管９から清水または原水供給管５から原水を供給して空の吸着槽２内を充たし、以後も洗浄水の供給を続ける。ついで搬送手段２２により新炭２３を搬送してホッパー１０内に供給し、活性炭加水器１１でホッパー１０内に清水を給水して新炭２３を加水しながら、ホッパー１０を通って吸着槽２内に投入し、吸着槽２内に運転に必要な量になるまで新炭２３を収容する。ついで洗浄水の供給継続下にエアリフトポンプ１２を運転して、下端の吸込み口１２ａから新炭と水とを吸込み、撹拌混合して洗浄しながら上端の吐出し口１２ｂから原水供給部Ａ側に吐出し、洗浄によって新炭から除去されたゴミや粉末炭などの夾雑物および新炭造粒時の油脂分を、仕切り板７の小孔８を通る経路と仕切り板７の下側を回る経路で洗浄水排出部Ｂに移行し、排水トラフ１７および洗浄水排水管１５を経て外部に排出する。これを１０〜３０分程度行う。 When using the new charcoal that is newly loaded into the adsorption tank 2 with activated charcoal, use the following. First, as shown in FIG. 5, fresh water is supplied from the fresh water supply pipe 9 as raw water or raw water from the raw water supply pipe 5 to fill the empty adsorption tank 2, and the supply of the washing water is continued thereafter. Next, the new charcoal 23 is transported by the transport means 22 and supplied into the hopper 10, and fresh water is fed into the hopper 10 by the activated carbon water heater 11 to hydrate the new charcoal 23, and then pass through the hopper 10 and into the adsorption tank 2. The new charcoal 23 is accommodated in the adsorption tank 2 until the amount required for operation is reached. Next, the air lift pump 12 is operated while the cleaning water is continuously supplied, and fresh coal and water are sucked from the suction port 12a at the lower end, mixed with stirring and washed, and then discharged from the upper discharge port 12b to the raw water supply unit A side. A route that passes through the small holes 8 of the partition plate 7 and the lower side of the partition plate 7 for dust, powdered coal, and other foreign matters discharged from the new coal by washing and cleaning, and oil and fat content during the granulation of the new coal. Is transferred to the washing water discharge section B, and is discharged to the outside through the drain trough 17 and the washing water drain pipe 15. This is performed for about 10 to 30 minutes.

このように新炭の使用時、吸着槽２への洗浄水供給下に、エアリフトポンプ１２で新炭と水を吸い上げ撹拌混合するので、吸着層２内に投入された新炭全体を十分に洗浄して、新炭に混入したゴミや粉末炭などの夾雑物および新炭造粒時の油脂分を除去して、吸着槽２外に排出することができる。したがって、新炭全体の吸着性能を有効に発揮させることができる。   Thus, when using fresh coal, the fresh coal and water are sucked up and mixed with the air lift pump 12 while the washing water is supplied to the adsorption tank 2, so the entire fresh coal introduced into the adsorption layer 2 is thoroughly washed. Thus, impurities such as dust and powdered charcoal mixed in the new coal and oil and fat during the granulation of the new coal can be removed and discharged out of the adsorption tank 2. Therefore, the adsorption performance of the whole new coal can be exhibited effectively.

以上説明したように、本発明の活性炭吸着装置によれば、吸着槽内の活性炭吸着層を十分に洗浄水と撹拌、混合して、活性炭に付着したＳＳを有効に洗浄し、吸着槽外に排出することができると共に、吸着槽からの廃炭の抜き出しと吸着槽への新炭使用時の洗浄も容易に実施することができる。   As described above, according to the activated carbon adsorption device of the present invention, the activated carbon adsorption layer in the adsorption tank is sufficiently stirred and mixed with the washing water to effectively wash the SS adhering to the activated carbon, and outside the adsorption tank. In addition to being able to be discharged, it is possible to easily remove the waste coal from the adsorption tank and clean the new adsorption coal in the adsorption tank.
