〔産業上の利用分野〕
本発明は油水分離装置に用いられる含油水濾過体に関し
、とくに微細に分散した油分を捕集し合体粗粒化させて
自ら浮上分離させる機能を有する構造化濾過体に関する
。[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to an oil-impregnated water filter used in an oil-water separator, and in particular has a function of collecting finely dispersed oil, coalescing it into coarse particles, and floating and separating it by itself. The present invention relates to a structured filter body having:
［従来の技術〕
含油水から油分を分離する処理方式としては、重力分離
法、濾過分離法、加圧浮」−法等の物理的処理、凝集沈
澱法、凝集浮上法等の薬剤処理、活性汚泥法等の生物学
的処理、吸着法等の物理化学的処理などが知られている
。[Prior art] Processing methods for separating oil from oil-containing water include physical treatments such as gravity separation, filtration separation, and pressurized flotation methods, chemical treatments such as coagulation-sedimentation and coagulation-flotation methods, and activated sludge. Biological treatments such as the method and physicochemical treatments such as the adsorption method are known.
このうち重力分離法に用いる装置として種々の形式のも
のが知られているが、分散油の径が比較的大きい場合に
は効果があるものの微細乳化油に対しては効果が少ない
ので、他の方法と併用して前処理として採用されること
が多い。また、濾過分離法は含油浮遊物及び一般の浮遊
物の除去には有効であるものの濾材の目詰まりが発生し
易く、詰まった油の除去が容易でない欠点がある。Among these, various types of devices are known for use in the gravity separation method, but although they are effective when the diameter of the dispersed oil is relatively large, they are less effective for finely emulsified oils, so other devices are used. It is often used as a pretreatment in conjunction with the method. Furthermore, although the filtration separation method is effective in removing oil-containing suspended matter and general suspended matter, it has the drawback that the filter medium is likely to become clogged, making it difficult to remove clogged oil.
凝集沈澱法、凝集加圧浮上法などは、残油分が５ ｐｐ
ｍ程度までの油分分離が可能であるが、薬剤を用いるた
め含油泥状物が発生して取扱いが面倒であるばかりでな
く原水中の油分の変動があると分離装置の運転制御が乱
れ易く、また装置の維持管理のために労力がかかる欠点
がある。Coagulation sedimentation method, coagulation pressure flotation method, etc. have a residual oil content of 5 pp.
It is possible to separate oil up to about 1.5 m, but since it uses chemicals, oil-containing sludge is generated, which is troublesome to handle, and if there is a fluctuation in the oil content in the raw water, the operation control of the separation device is likely to be disrupted. Another drawback is that it takes a lot of effort to maintain the device.
さらに、活性汚泥法は鉱物油を主成分とする含油水の処
理にはあまり有効でなく、また焼却処理は前述のような
処理方法によって濃縮された油分の処理には適するが、
未ｉ８ａ縮液の処理には経済的でない。Furthermore, the activated sludge method is not very effective for treating oil-containing water whose main component is mineral oil, and the incineration treatment is suitable for treating oil concentrated by the treatment method described above.
It is not economical to treat non-i8a condensate.
吸着法は、ポリプロピレン、ポリウレタン等の親油性合

を固定層内に充填し、これに含油水を通過させて油分を
吸着分離する方法であり、前述の各方法に比較して装置
が簡単で小型化でき、操作および保守管理も比較的に容
易である。しかしこの方法においても分離効率を高める
ために吸着体の充填密度を高めると通水圧損が大となり
、また吸着体の親油性を高めると油分が吸着飽和して分
離せずそれ以上の吸着能力が失われるのみならず共存す
る浮遊物質をも捕捉して通水圧損が一層大となる。そし
て逆洗によってもこれらの吸着油分や捕捉された浮遊物
質を取り除くごとは困難であり、使用寿命が短いなど経
済性に問題があった。In the adsorption method, a fixed bed is filled with a lipophilic synthetic resin such as polypropylene or polyurethane, an inorganic porous adsorbent such as diatomaceous earth or activated carbon, or a granular or fibrous adsorbent that is a combination of these. This is a method of adsorbing and separating oil by passing through it, and compared to the above-mentioned methods, the equipment is simpler and smaller, and operation and maintenance are relatively easy. However, even in this method, if the packing density of the adsorbent is increased in order to increase the separation efficiency, the water flow pressure loss will increase, and if the lipophilicity of the adsorbent is increased, the oil content will be adsorbed to saturation and will not be separated, resulting in no further adsorption capacity. Not only is it lost, but it also captures coexisting suspended solids, further increasing water flow pressure loss. Even by backwashing, it is difficult to remove these adsorbed oil components and trapped suspended solids, and there are problems with economic efficiency, such as a short service life.
また、これらの方法では除去しにくい乳化分散油滴を限
外濾過によって除去しようとすると、油が細孔に捕捉さ
れて濾過膜の寿命が極めて短いという欠点があり、実用
に適さない。Furthermore, when attempting to remove emulsified and dispersed oil droplets, which are difficult to remove by these methods, by ultrafiltration, the oil is trapped in the pores and the life of the filtration membrane is extremely short, making it unsuitable for practical use.
このような事情の下で、本発明者らは微細に分散した油

−２７２９）。しかし、この油水分離用フィルターは油
水分離性能にすくれており寿命も長いものの、耐食性が
不充分で反覆使用による劣化を避けることができなかっ
た。Under these circumstances, the present inventors developed a water-permeable water-absorbing filter that is mainly composed of a water-insoluble water-absorbing gel layer and is capable of efficiently collecting finely dispersed oil, coalescing it into coarse particles, and separating it. An oil/water separation filter characterized in that an oil/water separation functional layer having oil repellency due to occluded water is formed on a surface portion of a porous sheet that is to be brought into contact with oil/water and/or a liquid passage surface portion. Invented (Tokuko Sho 6) +
-2729). However, although this oil-water separation filter has excellent oil-water separation performance and a long service life, it has insufficient corrosion resistance and cannot avoid deterioration due to repeated use.
また一方、金属焼結体、磁器質多孔体、無機繊維質多孔
体等が固液分離用濾過体として用いられているが、これ
らの濾過体を油水分離処理に用いようとすると、油が濾
過体に付着して分離せず急速に濾過性能が低下するため
実用化し得るものではなかった。On the other hand, metal sintered bodies, porous porcelain bodies, inorganic fibrous porous bodies, etc. are used as filter bodies for solid-liquid separation, but when these filter bodies are used for oil-water separation, oil is filtered out. It could not be put to practical use because it adhered to the body and did not separate, resulting in a rapid decline in filtration performance.
本発明は前記のような事情に鑑みて、耐久性に優れかつ
従来の油水分離用フィルターでは適用不可能であった悪
条件下でも有効に使用できる改良された含油水処理用の
濾過体を、無機質材料を利用して実現しようとするもの
である。In view of the above circumstances, the present invention provides an improved filter body for oil-containing water treatment that has excellent durability and can be effectively used even under adverse conditions to which conventional oil-water separation filters cannot be applied. This is what we are trying to achieve by using inorganic materials.

。That is, as a result of carrying out various studies for such purposes, the present inventor has found that a filter body for oil-containing water treatment that promotes the physical association of fine oil cake in the pores inside the filter body; The destabilization of the emulsified state of oil cake, the adhesion and collection of oil cake to the filter body, and the desorption of the collected oil from the filter body must each exhibit harmonious effects. I was able to elucidate this. Based on this knowledge, we have completed the present invention.

When incorporated into paper, a sheet-shaped sintered body having desired properties can be obtained by low-temperature firing.

て実用上使用に耐えない。The sintered body of inorganic filler paper used in the present invention is selected to have an apparent specific gravity within the range of 2.0 to 3.0 and a porosity within the range of 8 to 30 mlf1/kg. It is used as a carrier. If the apparent specific gravity is smaller than this range, the strength as a filter, such as folding strength, will be insufficient and it will not be suitable for practical use.

On the other hand, the larger the porosity is, the more uniform the distribution of adhesion of water-absorbing particles to the carrier is, which is preferable; however, if it is too large, defects will increase, and if it is too small, it will be difficult for the collected oil to separate, leading to an increase in filtration pressure loss. .

The material may have various shapes obtained by, for example, making it into a cardboard shape and then firing it. However, it is desirable that the thickness of the sheet-like bodies constituting each part of these sintered bodies is about 0.1 to 2 mm; if it is less than this range, the mechanical strength will be insufficient, and if it exceeds this range, The porosity distribution within the sheet becomes wider, the oil removal efficiency decreases, and the service life tends to be shortened.

いることが必要である。In the oil/water separation functional layer mainly composed of water-insoluble water-absorbing gel, lipophilic substances such as paraffin, higher fatty acids, and rosin acid soaps, and water- and oil-repellent substances such as fluorine-based polymers are dispersed. They can be contained and retained non-uniformly by mixing them together or by chemically bonding them to a water-absorbing gel. When these substances are present in the water-absorbing gel, the destruction of the oil-water emulsion is promoted, and the efficiency of oil droplet collection and coarsening and flotation separation is improved. If they exist, they have no effect; they must be dispersed into independent islands.

から・濾過抵抗か大きくて不都合である。The water-insoluble water-absorbing gel constituting the oil-water separation functional layer has a solid content of 0.3 to 0.02 g/m based on the pore volume of the carrier.
It is necessary to carry it within the range of ℃. If the amount is less than this range, the captured oil will not be desorbed,
Filtration pressure loss rapidly increased, making it impossible to continue operation.
Also, if there is too much oil, clogging of oil will not occur, but the filtration resistance will be large from the beginning, which is inconvenient.

離を繰り返す。When the filter body for oil-impregnated water treatment of the present invention configured as described above is installed inside an oil-water separation tank and oil-impregnated water is passed through it, the oil content settles on the surface of the pores of the filter body. The water is separated from the water and the oil content is removed, and the water flows out to the other side. As water filtration of oil-containing water progresses, the oil trapped in the pores coalesces into 1'H particles, which are pulled away from the filter surface by the shearing force accompanying the water flow and become large-diameter oil droplets, which are then filtered through the filtration. It flows out with water. The filter body from which the oil droplets have been separated in this way repeats the collection, aggregation, and separation of oil again.
こうして流出した油滴ば浮七分離し易いので、油水分離

を失わずに使用できるものである。Such a filter body for oil-containing water treatment of the present invention prevents oil droplets separated from water and collected from accumulating in the pores.
Since it has the unique property of coalescing into granules and easily separating from the filter body, it can be used for a long period of time without losing its oil/water separation ability.

う特長を有する。The filter body for oil-containing water treatment of the present invention has excellent oil content law and can efficiently capture oil, and the captured oil does not accumulate in the filter body but is coarsened and released, so it can be used for oil-containing water treatment. The filtration resistance does not increase even if this is done continuously for a long time. Furthermore, oil droplets adhering to the surface of the filter have the effect of trapping impurities in oil-containing water, and can be separated and removed extremely efficiently by backwashing. Even if the filtration efficiency decreases due to adhesion and filling, it is possible to remove the oil and regenerate it by applying harsh treatment conditions such as extraction and thermal decomposition9.
