By putting waste liquid containing oil from above into the treatment tank where the oil adsorbent is placed, the oil adsorbent is adsorbed with oil, mixed with the stored water, and the waste liquid mixed water is filtered from the bottom. The oil is separated by passing through the wastewater and purifying it by returning to the treatment tank from the upper part for a predetermined time and purifying it, and draining the purified water obtained by this circulation from the treatment tank. Features.
Moreover, the oil-water separator of the present invention comprises a filter medium laid at the bottom as described in claim 2, stores a predetermined amount of water, and places a floating oil adsorbent on the liquid surface. After the waste liquid containing the oil component is introduced from above and the oil component is adsorbed to the oil adsorbent, the waste solution is mixed with the stored water, and the waste mixture water is discharged through the filter medium from the bottom. Further, it is characterized in that it comprises at least a circulation means for performing a circulation for returning to the treatment tank from the upper part for a predetermined time and a drainage means for draining the purified water obtained by this circulation from the treatment tank.

本発明によれば、油分を含む廃液に対し、効率よく、廃液の浄化が行えるとともに、油分の回収が行える、油水分離方法および油水分離装置を提供することができる。   According to the present invention, it is possible to provide an oil-water separation method and an oil-water separation device that can efficiently purify waste liquid and recover oil components from waste liquid containing oil.

以下、本発明の油水分離方法および油水分離装置について、図面を参照しながら説明するが、本発明は以下の記載に何ら限定して解釈されるものではない。   Hereinafter, the oil-water separation method and the oil-water separation device of the present invention will be described with reference to the drawings, but the present invention is not construed as being limited to the following description.

図１は、本発明の油水分離方法を実施する際の一形態を示す装置概念図である。油分を含む廃液（例えばラーメンの汁の飲み残し）Ｘが投入される処理槽１は、底部に濾材２が敷設されてなり、配管３から供給された所定量の水Ｙを貯留してその液面に水に浮遊性の油分吸着材４が配置されてなる。ここで、濾材２としては、袋詰めした活性白土などを用いることができる。水に浮遊性の油分吸着材４としては、各種の有機繊維や無機繊維からなるパッド形状のものを用いることができるが、とりわけ、カボック（Ceiba pentandra：アジア・アメリカなどの熱帯地方に分布するキワタ科インドワタノ属の高木）由来の天然繊維からなるものを好適に用いることができる（株式会社大和ホーム工業から商品名「ノヴァパッド」として販売されている）。処理槽１の上部には、食物くずを捕捉するためのバスケット５が設けられており、処理槽１の濾材２の下部には、袋からこぼれ出た濾材２が底部から流出しないように濾紙６が敷設されている。符号７は、廃液混合水の排出を容易にするとともに、濾紙６の形状を保持するために設けられた金網である。   FIG. 1 is an apparatus conceptual diagram showing an embodiment when the oil-water separation method of the present invention is carried out. The treatment tank 1 into which waste liquid containing oil (for example, left over ramen juice) X is placed has a filter medium 2 laid at the bottom, stores a predetermined amount of water Y supplied from the pipe 3, and the liquid The surface is provided with an oil adsorbent 4 which is floatable in water. Here, as the filter medium 2, activated clay packed in a bag can be used. As the water-floating oil adsorbent 4, pad-shaped materials made of various organic fibers and inorganic fibers can be used, but in particular, KAWOKA (Ceiba pentandra: KIWATA distributed in tropical regions such as Asia and America) Can be suitably used (sold under the trade name “Novapad” from Daiwa Home Industry Co., Ltd.). A basket 5 for catching food waste is provided at the upper part of the treatment tank 1, and a filter paper 6 is provided at the lower part of the filter medium 2 of the treatment tank 1 so that the filter medium 2 spilled from the bag does not flow out from the bottom. Is laid. Reference numeral 7 denotes a wire mesh provided to facilitate the discharge of the waste liquid mixed water and to maintain the shape of the filter paper 6.

処理槽１に、上方から油分を含む廃液Ｘを投入すると、油分は油分吸着材４に吸着され、油分吸着材４を通過した廃液は、貯留した水に混合される。槽内の廃液混合水の量が所定量に達すると、循環用ポンプ８の電源がオンになり、廃液混合水は、底部から濾材２を通過して排出され、配管９，１０，１１を経て再び処理槽１に上部から戻される。この循環を所定の時間行うことで、廃液に含まれていた種々雑多な成分が濾材２により捕捉され、廃液混合水を浄化することができる。所定の時間経過後に得られる浄化水は、配管１２を経て排水するか、配管１３を経て処理槽１の外部に設けた濾過器１４を通過させてさらに浄化してから配管１５を経て排水する。浄化水をこのように排水すると、油分を吸着した油分吸着材４が徐々に下降し、やがて濾材２に積層される。   When the waste liquid X containing oil is introduced into the treatment tank 1 from above, the oil is adsorbed by the oil adsorbent 4, and the waste liquid that has passed through the oil adsorbent 4 is mixed with the stored water. When the amount of the waste liquid mixed water in the tank reaches a predetermined amount, the circulation pump 8 is turned on, and the waste liquid mixed water is discharged from the bottom through the filter medium 2 and passes through the pipes 9, 10, 11. It returns again to the processing tank 1 from the upper part. By performing this circulation for a predetermined time, various miscellaneous components contained in the waste liquid are captured by the filter medium 2, and the waste liquid mixed water can be purified. The purified water obtained after the elapse of a predetermined time is drained through the pipe 12 or is further purified by passing through a filter 14 provided outside the treatment tank 1 through the pipe 13 and then drained through the pipe 15. When the purified water is drained in this way, the oil adsorbing material 4 that has adsorbed the oil gradually descends and is eventually stacked on the filter medium 2.

以上のようにして油分を含む廃液を油水分離した後は、油分を吸着した油分吸着材４と、廃液に含まれていた種々雑多な成分を捕捉した濾材２を処理槽１から取り外して廃棄すればよい。   After separating the waste liquid containing the oil as described above, the oil adsorbent 4 that has adsorbed the oil and the filter medium 2 that has captured various components contained in the waste liquid are removed from the treatment tank 1 and discarded. That's fine.

図２は、本発明の油水分離方法を実施する際のその他の形態を示す装置概念図である。この形態では、水Ｙをその液面がバスケット５の底面近くになるように貯留し、水に浮遊性の油分吸着材４をバスケット５の底面でその上部が押圧されるようにすることで水面下に沈降させて用いる（全部を沈降させずに一部を沈降させる配置であってもよい）。この形態によれば、上方から投入される油分を槽内に飛散させることなく油分吸着材４に確実に吸着させることができる。なお、槽内の廃液混合水の量は、図略のコントローラーにより排水と循環を制御することで一定に保てばよい。   FIG. 2 is an apparatus conceptual diagram showing another embodiment when the oil-water separation method of the present invention is carried out. In this embodiment, water Y is stored so that the liquid level is close to the bottom surface of the basket 5, and the upper surface of the floating oil adsorbent 4 is pressed against the water by the bottom surface of the basket 5. It is used by being allowed to settle down (may be an arrangement in which a part is settled without being completely settled). According to this embodiment, the oil component input from above can be reliably adsorbed to the oil component adsorbent 4 without being scattered in the tank. In addition, what is necessary is just to keep the quantity of the waste liquid mixed water in a tank by controlling drainage and circulation with a controller not shown.

なお、本発明の油水分離方法および油水分離装置は、油分を含む工業廃液を油水分離する際などにも利用することができる。   In addition, the oil-water separation method and the oil-water separation device of the present invention can also be used when, for example, oil-water separation of industrial waste liquid containing oil.

本発明は、油分を含む廃液に対し、効率よく、廃液の浄化が行えるとともに、油分の回収が行える、油水分離方法および油水分離装置を提供することができる点において産業上の利用可能性を有する。   INDUSTRIAL APPLICABILITY The present invention has industrial applicability in that it can provide an oil-water separation method and an oil-water separation device that can efficiently purify waste liquid and also recover oil from waste liquid containing oil. .
