摘要： PURPOSE:To treat sewage efficiently, by passing raw water into which oxygen has been dissolved through a ceramics fixed bed to which bacteria have been attached, passing thereafter water through a filtration tank of ceramics filter medium. CONSTITUTION:A mixed liquid of activated sludge is passed through ceramics fixed beds 5 of a bioreactor A to conduct aeration, thereby attaching bacteria to the ceramics. And raw water to be treated 1 is supplied to the bottom of the bioreactor A by means of a raw water feed pump 2 and at the same time aeration is carried out from an aeration pipe 4. While the raw water flows upwardly through an air lift pipe 5, oxygen is caused to be dissolved into the raw water to treat it biochemically. After the treatment, biochemical membrane treated water 8 is introduced into a ceramics filtration tank 12 to be filtered from the upper part of a ceramics filtration device B, while clean treated water 10 is discharged from the bottom thereof. In this manner, organic substances can be treated at a high efficiency.

摘要： PURPOSE:To prepare a carrier for immobilizing a microorganism without requiring a high temp. furnace and high temp. gas in baking the granulated slag of a shaft furnace, by kneading the granulated slag of the shaft furnace with a synthetic resin and molding the resulting mixture into a saddle or ring shape. CONSTITUTION:A thermosetting resin such as a phenol resin or a thermoplastic resin such as polyethylene is mixed with the granulated slag with a particle size of about 20-500mum in a compound ratio smaller than a shaft furnace granulated slag/synthetic resin + 1 on a wt. basis and the particles of the granulated slag of the shaft furnace are mutually bonded and molded into a saddle or ring shape at extremely low temp. without performing baking. Since the particles of the granulated slag of the shaft furnace are easily concentrated to the inside of the molded body, in this case, the molded body is treated so that the surface layer part thereof is peeled off by a mechanical means such as cutting to expose the much granulated slag of the shaft furnace to the uppermost surface. By this constitution, since the granulated slag of the shaft furnace is molded in a bonded state using the synthetic resin, a baking process reaching about 800 deg.C is omitted and a molded carrier can be obtained at low cost.

摘要： PURPOSE:To produce an optimum microorganism immobilized carrier for waste water treatment by compounding clay and pore forming material with blast furnace granulated slag and molding and calcining the mixture. CONSTITUTION:The clay such as KIBUSH clay is compounded at 0-40pts.wt. and the pore forming material such as sawdust at 5-20pts.wt. with 60-90pts.wt. blast furnace granulated slag having about 40-150mu grain size, then water is added to the mixture and the mixture is kneaded and is molded to the shape of a ring, saddle, etc., by extrusion molding or press molding. The molding is calcined. For example, the max. temp. at the time of the calcination is set at 900 deg.C and the temp. increase up to said temp. and the temp. decrease from said temp. down to

摘要： PURPOSE:To purify waste water with high efficiency by forming a packed bed with a ceramic having a specified shape as the filter medium in the biochemical treatment of waste water. CONSTITUTION:A ceramic filter bed 8 is provided in the ceramic filter A, and a ceramic saddle or ring having large surface area per unit area and void ratio is packed as the filter medium. Waste water is introduced into the filter bed 8 from the upper part of the filter A, the SS is collected by the ceramic, hence the water is purified, and the clean treated water 6 is discharged from the lower part. When the filter bed 8 is practically clogged, air is introduced from an air diffuser pipe 5 by a backwashing blower 4, water is also introduced by a backwashing pump 3, and the deposited SS is almost completely removed.

摘要： PURPOSE:To treat waste water with high efficiency by using saddle type or ring type ceramic as a ceramic carrier consisting mainly of blast furnace slag. CONSTITUTION:When mixed liquid of activated sludge of sewage is introduced into an aeration tank as seeding sludge, activated sludge is infiltrated into the gaps of ceramic. A first aeration tank 2 and a second aeration tank 3 become nearly transparent when a given time elapses. Then the first and second aeration tanks 2, 3 are aerated by sucking air or oxygen through diffusers 11 for aeration. Waste water is passed to regulate apparent passage time wherein waste water passes through the first and second aeration tanks 2, 3 to prescribed value and treating time is successively shortened for acclimatization of activated sludge. The aeration amount of gas for aeration is controlled via a solenoid valve 10 with an ORP controlling device 5 activated by an ORP sensor 4. Thereby necessary motive power can be reduced.

摘要： PURPOSE:To prepare a carrier for immobilizing a microorganism without required a high temp. furnace or high temp. gas in baking the granulated slag of a shaft furnace, by adhering the particles of the granulated slag of the shaft furnace to a carrier material molded into a saddle or ring shape through an adhesive layer. CONSTITUTION:An adhesive layer having a thickness of about 0.1mm or more is formed to the surface of a carrier material composed of a synthetic resin molded into a saddle or ring shape using an adhesive composed of a thermosetting resin such as a phenol resin, an adhesive composed of a thermoplastic resin such as vinyl acetate or an inorg. adhesive such as Portland cement. Next, the particles of the granulated slag of a shaft furnace having a particles size of about 20-500mum are adhered to the carrier material through the adhesive layer and the adhesive is cured in such a state that the particles of the granulated slag of the shaft furnace are bonded. In this case, the adhesive layer many be formed by melting the surface of the carrier material composed of the synthetic resin by heat or a solvent such as methanol to embed the granulated slag of the shaft furnace in the molten layer. By this method a baking process reaching 800 deg.C is omitted and the molded body of a carrier can be obtained at low cost.

摘要： PURPOSE:To make it possible to treat water drained from a step of manufacturing cold-rolled steel sheets at high efficiency after pressurized floatation by treating drained water using microbes acclimatized with the help of activated mud or sludge for treating sewage and industrial waste water in a fluidized bed-type bioreactor. CONSTITUTION:An activated mud mixed liquid for treatment of sewage and industrial waste water is poured into a fluidized bed-type bioreactor 1, and water drained from a cold-rolled steel sheet manufacturing step is gradually supplied while maintaining the conditions suited for the decomposition of a COD component contained in the drained water after pressurized floatation. Thus, microbes which decompose the COD component by oxidation are allowed to proliferate easily. In this case, if a suspended substance which contains a sufficient amount of flocculating agent generated at the time of pressurized floatation is added thereto, activated mud is granulated, then the washout of useful microbes decrease and the microbes are easily acclimatized. As described, water drained from a step of manufacturing the cold-rolled steel sheet after pressurized floatation is treated by using the microbes which decompose the COD component used for the acclimation and culture of the microbe.
