摘要： PROBLEM TO BE SOLVED: To effectively increase the amt. of water to be permeated through a membrane and to suppress the decrease thereof with lapse of time by adding a ceramic powder to a mixed soln. contg. a formed sludgy reactant, fluidizing the mixture and cleaning the surface of the membrane with the ceramic powder in the liq. mixture. SOLUTION: The original waste water contg. org. matter is introduced into a regulating tank 21 and then supplied to a bioreactor 22. The org. matter contained in the waste water is oxidized and decomposed with the aerobe in an oxygen-contg. gas from a blower 23a to form a mixed soln. contg. a sludgy reactant, and a ceramic powder is supplied to the soln. from a powder feeder 29. The secondary side of a membrane module in a membrane separator 27 in the mixed soln. is sucked by a vacuum pump 28 and evacuated, and treated water is obtained as the water permeated through the membrane. At this time, since the ceramic grain is fluidized at all times, the membrane surface is ground and cleaned, and the deposition of an org. high molecular substance on the membrane surface is suppressed.

摘要： PURPOSE:To obtain the deodorizing method and device which form a deodorant mixture composed of earthworm excreta earth and granular active carbon and can remove even the malodorous components which are relatively hardly removable by passing gases before deodorization through this deodorant mixture. CONSTITUTION:While the gases contg. the bad odors via a suction pipe 4 pass vent holes 8a of a perforated plate 8, the gases pass among grains 10 and the inside of the layer of the deodorant 12, the malodorous components are removed by the earthworm excreta earth and the granular active carbon. The gases are then discharged from the upper part of a box body 2 to the outside. The earthworm excreta earth tends to solidify on long-term use but since the deodorant 12 is formed by mixing the earthworm excreta earth and the granular active carbon, the deodorant hardly solidifies. The air permeability is thus assured and the deodorizing effect is continued. Then, even the malodorous components which are relatively hardly removed by the earthworm excreta earth are adsorbed and removed to and by the granular active carbon. The gases contg. the various combined components are thus effectively deodorized and the high deodorizing capacity to various smells is exhibited.

摘要： PROBLEM TO BE SOLVED: To obtain a method for treating waste containing a large quantity of moisture and utilizing the treated refuse as fuel or reducing agent by concen trating water separated from the waste and combusting it together with the waste, partially oxidizing/gasifying it under existence of a gas containing oxygen or distilling/carbonizing it. SOLUTION: Separation water standing in the bottom part of a pit for water containing refuse is heated and concentrated by means of a concentrator 30 disposed in a separation water treating unit to reduce a concentrated matter. The concentrated matter is fed to a combustor, a partially oxidizing/gasifying unit or a distilling/carbonizing unit, where it is combusted together with the refuse or partially oxidized or distilled/carbonized under coexistence with oxygen gas. Refuse containing a large quantity of moisture, e.g. sewage sludge or raw refuse, can be treated without lowering the capacity of a refuse treating facility and treated refuse can be utilized effectively as fuel or a reducing agent.

摘要： PROBLEM TO BE SOLVED: To suppress a reduction of a membrane permeated water quantity with time due to an adhesion.deposition of a high polymer, etc., to a membrane module by subjecting a mixed soln. containing a slurry product formed in an aeration tank to an ozone treatment, then obtaining a treated water by subjecting this mixed soln. to a solid liq. separation with a membrane separating device. SOLUTION: When a raw waste water containing an org. material is supplied to an aeration tank 12 from a regulating tank 11, the org. material in the waste water is decomposed oxidatively with an aerobic bacteria working actively by aeration to an air sent from an air diffuser 14 and an activated sludge is formed. In this case, an ozone treating device 22 is connected to the aeration tank 12 with a piping, and after subjecting the mixed soln. (activated sludge) 15 containing the slurry product formed in the aeration tank 12 to the ozone treatment, the mixed soln. 15 is subjected to the solid-liq. separation with the membrane separating device 16. That is, a fibrous material inflowing from the raw waste water and preventing the membrane separation is decomposed and conveted into low molecule by the ozone treatment, and also sugars are reduced to reduce a viscosity of the mixed soln. 15 and the reduction of the membrane permeated water quantity with time is suppressed.

摘要： PURPOSE:To remove not only phosphorus or biodegradable org. matter and hardly biodegradable org. matter but also nitrogen by forming a soil trench having an upper permeable trench pipe and a bottom water gathering trench pipe built therein in soil and forming an anaerobic region to the bottom part of the soil trench so as to freely adjust the volume thereof. CONSTITUTION:After a water impermeable sheet 1 is laid, upper water permeable trench pipes 2 and a bottom water gathering trench pipe 3 are arranged. Sewage secondary treated water 4 is allowed to flow in the upper water permeable trench pipes 2 to be allowed to penetrate in soil. The treated water 4 is purified by aerobic bacteria in soil to be recovered from the bottom water gathering trench pipe 3. At this time, the part above the water level in the bottom water gathering trench pipe 3 is unsaturated with water but the part therebelow is saturated with water and the saturated region becomes an anaerobic region 6, and nitrogen can be removed by the denitrifying action of anaerobic bacterial. By this method, not only phosphorus or medium and low concn. org. matters but also nitrogen can be removed and, by properly controlling the anaerobic region 6, high order treatment of a high removing rate can easily be carried out.

摘要： PROBLEM TO BE SOLVED: To effectively suppress secular decrease of a membrane-transmitted water quantity and to increase the treating quantity by filtering a mixture solution incorporating sludge substance formed in an aeration tank with a membrane module, also feeding alkaline water produced with a membrane type electrolysis device to a secondary side of the membrane module and washing the membrane. SOLUTION: Raw discharge water containing organic substance passes through from an adjustment tank 11 to an aeration tank 12 and is oxidized and decomposed with aerobic bacteria working with aeration from a diffuser 14 and forms a sludge-like reaction substance-containing mixture solution 15, namely activated sludge. Also the treated water is obtained as the membrane-transmitted water by immersing the membrane module 17 into the aeration tank 12, and sucking the secondary side of the membrane module 17 with a suction device 18 and evacuating. At this time, acidic water and alkaline water are produced by the membrane type electrolysis device 20 and the acidic water is fed to the treated water at an operation time of a membrane separation device 16 to neutralize the treated water, and the alkaline water is fed to the secondary side of the membrane module 17 at a stop time of the membrane separation device 16 to wash the membrane module 17.
