摘要： PURPOSE:To obtain the catalyst whose specific gravity and particle size can be freely adjusted, by sticking and supporting a metallic catalyst such as a porous metallic catalyst on the surface of foamed plastic particles such as the particles of foamed polystyrene to form the catalyst useful for the purification of waste water. CONSTITUTION:A granular or powdery metallic catalyst is stuck or applied to particles prepared by heating and foaming plastics such as polystyrene with gas or a foaming agent to form the catalyst useful for the purification of waste water. Foamed polystyrene, foamed propylene, foamed polyethylene, etc. may be used as the foamed plastics, and its particle size is generally at 1-10mm.. A metal itself or a metal supported on alumina, zeolite, active carbon or the like may be used as the metallic catalyst. The obtained catalyst is preferably used at a low temperature especially below 100 deg.C, preferably at an ordinary temperature.

摘要： PURPOSE:To avoid closure of powder bearing layer by bearing particles by supplying drainage in downstream flow to utilize a bearing fluidized floor floating on the water to thereby maintain high biological reaction speed so as to reduce the size of the device. CONSTITUTION:Drainage is treated by immersing powder bearing floawing on the water with lighter apparent specific weight than water in water, adhering biology thereto in floated state, introducing the drainage through the powder bearing layer in downstream flow, and treating it in contact with the biology upon passing thereof through the layer to thereby recover treated water layer from the bottom. According to this method, nitrogen gas produced by the denitrifying reaction becomes small bubbles to rise in the fluidized floor to eliminate the disadvantages of the conventional upstream flow method such as introduction of floating the bearing particles, the increase in the powder amount flown with the treated water, but to be preferable for formation of fluidized layer. Since it is aerobic treatment, the air fed from the bottom of the floor performs the same as the nitrogen gas as air bubbles.

摘要： PURPOSE:To accomplish re-use of water containing a carrier and a peeled off microorganism by circulating the water as is through the bottom of a fluidized bed in a method of denitrifying waste water by forming a fluidized bed empolying a carrier having the microorganism attached thereto. CONSTITUTION:Raw influent 1 is injected into the bottom of a reaction column and evenly dispersed by a dispersion plate 3. Then, together with circulating treating water fed on to the dispersion plate 3 with a circulating pump 12, it fluidizes a medium having microorganisms attached thereto in such a manner as to form a fluedized bed 4 for denitrification. A part of the treating water reaching the top of the column is withdrawn from a line 11 to be inducted into the column again as a circulating treating water with the circulating pump 12 while the remainder thereof is drained out of the top of the column as treated water. The circulating pump 12 sucks the medium with sludge attached, peels the sludge off the medium by a shearing force of sucking pump blades, and finally sends the sludge and the medium to the bottom of the fluidized bed.

摘要： PURPOSE:To carry out the membrane separation of low cost without providing excess membrane modules by presuming the fluctuation of permeating flow velocity according to the fluctuation of the temp. of water to be treated, and adjusting the membrane surface flow velocity so as to compensate the fluctuation of the permeating flow velocity to control the permeated water quantity to be constant. CONSTITUTION:Impurities are removed from the water to be treated the temp. of which is fluctuated in the passage of time by the circulating filtration system of a membrane unit 10. In this case, the temp. fluctuation of the water to be treated is detected by a water temp. measuring means 8, and the fluctuation of permeating velocity due to the detected temp. fluctuation is presumed by a data processing means 7. A circulation pump control means 6 adjusts the number of revolution of a circulation pump 5 to obtain a specified membrane surface flow velocity so that the presumed fluctuation of permeating velocity is compensated. As a result, the permeated water, quantity is kept constant, and the membrane separation of low cost, of saved space, and of saved energy is carried out without providing excess membrane modules.

摘要： PURPOSE:To make it possible to efficiently separate a reaction product substance, by sterically entangling fine wiry materials consisting of a microbial carrier, binding at least part of mutual contact parts of the wiry materials and using the resultant wiry materials for a bioreactor. CONSTITUTION:A biological reaction substrate is introduced into a reaction tank filled with a microbial carrier and microorganisms to carry out microbial reaction and take out the biological reaction product. In the process, the microbial carrier is constituted of fine wiry materials obtained by sterically entangling the materials and binding at least part of the mutual contact parts thereof and having complicated space are used to keep the microbial carrier and the microorganisms in an immobilized state. The reaction tank is divided into many stages by effective partition plates, and the microbial carrier having a large particle diameter is filled in the first stage. The microbial carrier is filled in the respective stages so that the particle diameter in the stages may vary with the stages one after another decreasing toward the final stage.

摘要： PURPOSE:To provide a carrier particle producible continuously at a low cost, capable of immobilizing microorganisms in high concentration, and useful for the stable bioreaction such as fermentation and water-treatment, etc., by winding a yarn or fiber around a plastic substrate having notches at the outer surface. CONSTITUTION:A yarn or fiber (natural or synthetic fiber, preferably a tape or sheet woven by filament of 0.1- several tens mu diameter or a yarn having a thickness of several tens - several hundreds mu in view of tensile strength) is wound around a plastic substrate having notches at the outer surface (a thermoplastic resin or thermosetting resin such as PE, PS, polyurethane, etc. preferably having a length and diameter of 1-50mm.), to obtain the objective carrier. It can immobilize microorganisms, etc. in high concentration. Although excess microorganisms are sometimes released from the gap between the yarns and fibers according to the progress of proliferation, and dissipated from the system by the flow and vigorous agitation of the carrier particles, however, the microorganisms retained in the inside of the carrier are resistant to the release. Accordingly, the carrier is suitable to use in the form of fluidized bed or mixed bed, etc.
