摘要： PURPOSE:To circulate a mixed liquid by always positioning a hollow fiber membrane module in the mixed liquid even when the water level of the mixed liquid in a treatment tank is varied by providing a large number of hollow fiber membranes moving up and down along with a movable pipe moving up and down corresponding to the fluctuation of a water level and circulating the mixed liquid in the treatment tank. CONSTITUTION:A fixed pipe 7 is set to the central part of a treatment tank 1 and a movable pipe 8 is externally fitted to said fixed pipe 7 so as to be slidable up and down with the rising and falling fluctuation of a water level WL by a buoyancy means 9 such as a float ring. A hollow fiber membrane module 2 and the movable pipe 8 are integrally connected and moved up and down with the fluctuation of the water level. The mixed liquid in the pipes 7, 8 is discharged out of the pipes by a screw 10 to be circulated in the treatment tank. By this constitution, the movable pipe and the hollow fiber membrane module moves up and down corresponding to the fluctuation of the water level of the mixed liquid and the hollow fiber membrane module is positioned in the mixed liquid to make it possible to effectively circulate the mixed liquid.

摘要： PROBLEM TO BE SOLVED: To provide an immersion type membrane separation and activated sludge apparatus for which flow rate-adjusting tank is not needed, which provides treated water with high quality even through a compact size, in which the quantity of the blowing air can be remarkably lessened as a whole, and of which the treatment function can be made appropriate. SOLUTION: This apparatus is constituted of an aeration tank 1 housing a membrane module 2 and an aeration pipe 3 and a treated water tank 7 to take treated water put of the aeration tank 1 through a siphon 9. The apparatus is so designed as to keep the water level change of the aeration tank 1 within a range from the highest water lever HWL and the lowest water lever LWL based on the estimation of the maximum flow rate of organic wastewater flowing into the aeration tank 1 and also as to keep the membrane surface of the membrane module 2 always under the lowest water level LWL and immersed in the wastewater and at the same time the membrane module 2 is so constituted as to be possible to treat the wastewater at the maximum inflow amount. Furthermore, the quantity of the treated water to be taken out is controlled based in the highest water lever HWL and the lowest water level LWL.

摘要： PURPOSE:To efficiently control intermittent suction by placing plural hollow-fiber membrane modules in a liq. mixture and providing a control valve to a suction branch pipe. CONSTITUTION:The control valve V1 is opened at the timing of T1 and closed at the timing of T1', and the control valve V2 is opened at the timing of T2 and closed at the timing of T2'. When the control valve V is opened, only the liq. part in the mixture in a treating tank 2 except the solid matter, microbes, etc., is sucked into a suction chamber 1c through the tiny hole of the hollow-fiber membrane 1b, and the permeated liq. is collected in a suction main pipe 4 and sucked into a vacuum receiver tank 5. When the level is raised to a specified value in the tank 5, the fact is detected by a level controller 5a, and a suction pump 8 is operated. A desired suction is rapidly obtained in this way.

摘要： PURPOSE:To rapidly produce the hollow-fiber membrane bundle with high precision by applying an adhesive on many arranged hollow-fiber membranes to form a rolled junction and opening the hollow hole of the membrane at the tip surface of the junction to form a suction chamber. CONSTITUTION:Many hollow-fiber membranes 1 are closely arranged in parallel, and an adhesive is orthogonally applied to form a band-shaped junction having a specified width. The junction is rolled and rounded, and the adhesive is injected into the gap to form a rolled junction 5. The junction 5 is cut by a cutter at its center to form two sets of hollow fiber membranes. The hollow hole of the membrane 1 is opened at the tip surface of the junction 5, and a cap 8 is integrally fixed to form the suction chamber 8a. The free end of the membrane 1 is appropriately sealed. Consequently, the hollow-fiber membrane bundle is mass-produced rapidly, precisely and at a low cost.

摘要： PURPOSE:To eliminate the disorder and entanglement of hollow-fiber membrane, to prolong the service life, to easily exchange the membrane and to standardize the capacity, scale, etc., by intermittently sucking the inside of the hollow-fiber- membrane module packed in a solid-liq. separation tank. CONSTITUTION:A hollow-fiber-membrane module 13 is packed in a solid-liq. separation tank 12, and an activated sludge-mixed liq. 8 is introduced into the tank 12 from a bioreactor 3. The inside of the hollow-fiber membrane 13b in a suction chamber 13 is intermittently sucked by a suction device 15, and the liq. mixture 8 is separated into solid and liq. The operating time of the suction device 15 is appropriately set by an intermittent timer 16, and the sucking time and downtime are changed. As a result, the handling is facilitated, and the capacity can be standardized. Furthermore, the entanglement of the membranes is eliminated, and the service life is prolonged.

摘要： PURPOSE:To eliminate the disorder and entanglement of hollow-fiber membranes, to prolong the service life of the membrane, to easily exchange the membrane and to standardize the capacity, scale, etc., by packing many bundles of membranes freely movably into a honeycomb tube. CONSTITUTION:An air diffuser pipe 6 is arranged at the bottom of a bioreactor 3, air is supplied to the pipe 6 from an aeration blower 7, hence the org. matter introduced into the bioreactor 3 is adsorbed on an aerobe floc, oxidized and decomposed, and the sewage is purified. A liq. mixture introduced into a solid- liq. separation tank 12 is sucked into a suction chamber 13c through the micropores of the hollow-fiber membrane 13b in the honeycomb tube 13a, and the permeated liq. is drawn off from a water pipe 17 as treated water. Since many hollow-fiber membranes are packed in the honeycomb tube and modularized, the handling is facilitated, and the capacity can be standardized. The entanglement of the membranes is eliminated, and the service life of the membrane is prolonged.
