Abstract

PURPOSE:To eliminate the entanglement of hollow fibers and to facilitate the handling and fabrication by fixing and supporting the ends of the hollow-fiber membranes by a suction pipe in communication with one another and forming the membrane with weft and warp in the shape of woven fabric. CONSTITUTION:When a housing H is arranged in an aeration tank to treat waste water, inclusions such as sludge are separated on the surface of a hollow- fiber membrane 2 by the operation of a suction pump, and the filtered water is passed through the weft and warp, collected in the suction pipes 1A, 1B, 1C and 1D on the circumference and further drawn off to the suction pump side through collecting pipes 3A, 3B, 3C and 3D. In this case, if the pitch of the weft and warp constituting the membrane 2 is decreased, the membrane area per volume is increased, and solid-liq. separating performance is enhanced. Further, the membrane 2 is formed as the woven fabric of weft and warp, hence the weft and warp are not entangled with each other, and the cleaning effect is heightened.

【0010】本例における前記中空糸膜2は、図2または図3で示すように、縦糸2aと横糸2bが織物状に織られて形成されたものであり、図2は平織り状に織られたものであり、また図3は綾織り状に織られたものである。 [0010] The hollow fiber membrane 2 in the present embodiment, as shown in Figure 2 or Figure 3, which warp 2a and weft yarns 2b are formed are woven into a fabric-like, FIG. 2 is woven into a plain weave form it is as hereinbefore, and FIG. 3 are those woven like twill. 各横糸2b,2b間のピッチaおよび各縦糸2a, Each weft 2b, pitch a and the warp 2a between 2b,
2a間のピッチb、および図3の綾織りにおける横糸間のピッチcは極力0に近いピッチ間隔にすることが好ましく、極力小さいピッチ間隔にすることによりa〜c間に夾雑物が挟まることを防ぐことができ、夾雑物が挟まりそれを起点にして髪の毛や糸くず,汚泥等が成長をすることを良好に防ぐことができ、また、容積当りの膜の集密度を高めることができる。 Pitch b between 2a, and pitch c is preferably set to minimize pitch near zero between the weft in twill in FIG 3, that contaminants sandwiched between a~c by as much as possible small pitch can be prevented, hair and lint as a starting point it contaminants caught, can be prevented satisfactorily the sludge to growth, also, it is possible to increase the current density of the membrane per volume. なお、各縦糸2aおよび横糸2bは、外径が0.4mm程度で内径が0.3mm程度の中空糸で形成されたものであり、中空糸の表面には微細な細孔が形成されている。 Each warp 2a and weft 2b are those outside diameter is formed in the hollow fiber inner diameter of about 0.3mm at about 0.4 mm, on the surface of the hollow fibers are fine pores formed . 例えば、前記縦糸2aおよび横糸2bはそれぞれ2千本から5千本程度の本数で織り上げて1枚の中空糸膜2を形成することができる。 For example, the warp 2a and weft 2b can form a hollow fiber membrane 2 in one weaving in the number of about 5,000 trees from 2 thousand respectively.

【0011】したがって、図1のようなハウジングHを曝気槽62内に配置させて排水処理を行なえば、吸引ポンプ65の作動により中空糸膜2の表面で汚泥等の夾雑物が分離され、濾過された状態の処理水が各縦糸2a, Accordingly, by performing the wastewater treatment by placing the housing H as shown in FIG. 1 to the aeration tank 62, contaminants sludge at the surface of the hollow fiber membrane 2 is separated by the operation of the suction pump 65, filtration state of the treated water each warp 2a,
横糸2b内を通り、四周の吸引管1A,1B,1C,1 Through the weft thread 2b, four sides of the suction pipe 1A, 1B, 1C, 1
Dに集められ、さらに集合管3A,3B,3C,3Dを介し吸引ポンプ65側へ引き抜かれるものであり、中空糸膜2を構成する縦糸2aと横糸2bの各ピッチ間隔を極めて小さいものとしておけば、中空糸膜2表面の夾雑物の集積量が極めて高くなり、コンパクトな形状にかかわらず容積当りの膜面積が極めて大となり、固液分離機能が極めて高くなる。 Collected in the D, further collecting pipe 3A, 3B, 3C, are those withdrawn to the suction pump 65 side through a 3D, Oke and each pitch interval of the warp 2a and weft 2b constituting the hollow fiber membrane 2 extremely small in the hollow fiber membrane 2 accumulated amount of contaminants on the surface is very high, membrane area is very large next per volume regardless compact shape, the solid-liquid separating function is very high.

【0012】また、中空糸膜2は縦糸2aと横糸2bを織物状として形成したものであるため、縦糸2aと横糸2bのそれぞれの糸同志の絡みあいが全くなくなり、従来のように糸が絡みあって束になることがなく、散気管63からエアを噴出させて表面を洗浄する時にも、エアおよびエアに伴う水流が良好に中空糸膜2の全域におよび、良好に表面に付着した夾雑物等を剥離させて脱落させることができ、洗浄効果が極めて高いものとなる。 Further, since the hollow fiber membrane 2 is obtained by forming a warp 2a and weft 2b as woven, entanglement of the respective yarn comrades warp 2a and weft 2b is eliminated completely, yarn entanglement as in the prior art without to be bundled there, when cleaning a surface by ejecting the air from the aeration tube 63, contaminating the water flow caused by the air and the air is better and the entire hollow fiber membrane 2, and adhere well to the surface can be shed by peeling things like cleaning effect is extremely high. また、織物状であるため、運搬中およびセット時等にも糸同志が絡み合うことがなくなり、取扱いが極めて容易なものとなる。 Moreover, because it is woven, it is not possible to intertwined threads each other even during the transport and set or the like, handling becomes extremely easy. また、縦糸2aと横糸2bにより織り上げられているため、局部的な糸の引っ張りがなくなり、糸切れを良好に抑止することができる。 Moreover, because it is woven by warp 2a and weft 2b, there is no tension localized yarn can be satisfactorily suppressed yarn breakage. なお、従来では膜と吸引管との固定が極めて困難であったのが(従来では糸の上下の順番を合わせて吸引管に固定する必要がある)、本案のものでは織物状となっているため、縦糸2 In the prior art (it is necessary to fix the suction tube to fit the order of upper and lower yarns in the conventional) that fix the membrane and the suction tube is very difficult, by way of merits has a woven Therefore, the warp 2
aおよび横糸2bはそれぞれ所定ピッチ間隔で最初から固定状態となっており、そのままの状態で吸引管1A, Each a and weft 2b has a first fixed state at a predetermined pitch, the suction pipe 1A as it is,
1B,1C,1Dに端部を差し込んで容易に糊付け等で固定することができ、固定作業を極めて容易に行なえるものである。 1B, 1C, insert the end can be fixed with ease gluing or the like to 1D, it is extremely easy to perform the fixing operation.

【発明の効果】本発明は、中空糸膜の端部を吸引管で連通状に固定支持してなる中空糸膜モジュールであって、 According to the present invention, a hollow fiber membrane module formed of a fixed support to the communication like the ends of the hollow fiber membranes by a suction tube,
前記中空糸膜は、横糸と縦糸で織物状に形成されていることにより、従来のような糸同志の絡みあいがなくなり、糸が束状になることがなく、エアおよび水流による洗浄を極めて良好に行なうことができ、洗浄効果が高いものとなる。 The hollow fiber membrane, by being formed into a fabric-like weft and warp, entanglement is eliminated in a conventional manner such yarns comrades without yarn is a bundle, very good cleaning with air and water flow can be done, it becomes cleaning effect is high. また、運搬中およびセット中等に糸が絡みあうことがないため、取扱いが容易なものとなり、また局部的な糸の引っ張りがなくなり、糸切れが抑止できる効果を有する。 Since it is not possible to each other yarn tangled during transport and set secondary, handling becomes as easy and there is no tension localized yarns, has the effect of yarn breakage can be prevented. さらには、容積当りの膜の集密度を高めることができ、モジュールをコンパクト化でき、また、 Furthermore, it is possible to increase the current density of the film per volume, can compact module, also,
吸引管に対し中空糸膜の上下位置を合わせる煩雑な製作加工が不要となり、モジュールの製作が容易で大量生産し易い効果を有する。 Complicated production process to align the vertical position of the hollow fiber membrane to the suction pipe is not necessary, having easily effect fabrication of a module is easy mass production.
