摘要： PURPOSE:To improve the removal effect of malodor, to prevent the degradation in catalytic activity and to extend the life of catalysts in removal of malodor by an ozone catalyst method by passing malodorous gases through an active carbon filter then injecting ozone thereto. CONSTITUTION:The malodorous gases generated from sewer treatment facilities, etc. are passed through an active carbon filter 2 whereby the hydrocarbons in the gases are adsorbed and removed. Ozone from an ozone generator is injected to the gases past the filter 2 and while these are mixed, the gases are fed to a gas mixing tank 4 where the gases and ozone are mixed thoroughly, and gas phase reaction is accelerated. The gaseous mixture is fed to a catalytic reactor 5, where the reaction of the unreacted malodorous components and the ozone is completed. By this method, the degradation in catalytic activity is prevented without adsorption and accumulation of the hydrocarbons on the catalyst surfaces of the reactor 5.

摘要： PURPOSE:To improve filtering capacity by washing a filtering cylinder sufficiently, by rotating a porous filtering cylinder in the inside of a cylindrical magnet having a lacked part, at a filtering apparatus which utilizes a magnetic field and purifies muddy water containing floating matters. CONSTITUTION:A cylindrical magnet 9 being lacked a part of it, is arranged at the lower outside of a vessel 3 of which lower part is formed into a cylindrical shape 3a. A porous filtering cylinder 5 made of a material easily being magnetized in a magnetic field and having small residual magnetism, is supported by bearings 4 in the vessel 3 and is rotated; air bubbles 16 are discharged from holes 17 of an air blow pipe 8 installed at the center of the cylinder 5. While raw muddy water 1 charged from the upper side passes through the cylinder 5, easily magnetizable floating matters are stuck to the cylinder 5 and magnetized by a magnetic field of a magnet 9. The cylinder 5 is degaussed by the magnet- lacked part, and the floating matters are separated from the cylinder 5, and are captured by rising bubbles into a muddy-water introducing cover plate 12 arranged at the upper side, and then discharged by an exhausting pipe 11. Purified water is extracted to the outside through the air blowing pipe 8 by a gutter 13.
