摘要： PROBLEM TO BE SOLVED: To provide a nitrogenation method effective even on the waste water with the temperature lowered and the load fluctuated as a nitrogenation process using a fixed carrier. SOLUTION: A part or the whole of the sludge settled in a settling tank set up in the rear of a denitrification tank or a nitration tank is circulated to the nitration tank or the denitrification tank. Consequently, the activated sludge concentration is secured in the denitrification tank or the nitration tank even when the water temperature is lowered or the load is fluctuated and the microbial biomass is dificient, and nitrogenation is stably performed.

摘要： PROBLEM TO BE SOLVED: To prevent the degradation in treatment efficiency by nitrite nitrogen and to execute stable nitrogen removal by oxidizing the ammonia nitrogen included in waste water to the nitrite nitrogen by a biological treatment, then reducing the nitrite nitrogen to gaseous nitrogen and removing the same from the waste water by a biological denitrification method using autotrophic bacteria. SOLUTION: The nitrite nitrogen is reduced to the gaseous nitrogen by using the autotrophic bacteria having resistance to the nitrite nitrogen in the denitrification stage. The autotrophic bacteria, such as hydrogen bacteria and sulfur oxidation bacteria, are respectively microorganisms for synthesizing and propagating microbial cells from the energy generated when hydrogen and a reducing sulfur compound are oxidized and carbon dioxide in the air. More particularly, the sulfur oxidation bacteria among the autotrophic bacteria have a self-granulation effect and, therefore, facilitate the enhancement of the efficiency of the concentration increasing treatment in a reactor and are optimum as the autotrophic bacteria. The autotrophic bacteria having the resistance to the nitrite nitrogen are used in the manner described above, by which the stable treatment of the waste water containing a high-concentration ammonia is made possible.

摘要： PROBLEM TO BE SOLVED: To treat water efficiently by restraining photorectivation of microorganisms while defects of ultraviolet disinfecting and phtocatalytic disinfection are compensated as a disinfecting method in place of a chlorine disinfection method. SOLUTION: When water to be treated is irradiated with ultraviolet radiation from ultraviolet lamp 2, a photoreactivation phenomenon of microorganism is restrained by irradiating cylindrical platy photocatalytic supports 9 to 12 arranged so that a photocatalyst having titanium dioxide, etc., as a main constituent and water to be treated come to be contact with each other simultaneously with ultraviolet radiation. As the ultraviolet lamp 2, a medium pressure or high pressure mercury lamp is preferably used. Thereby, the photoreactivation phenomenon of the microorganisms is restrained by a disinfection effect of free radicals having intensive oxidation force generated with the photocatalyst irradiated with ultraviolet radiation in addition to a direct disinfection effect of ultraviolet radiation, and effective disinfection can be executed.

摘要： PURPOSE:To make water pass thoroughly all over a valve so as to enhance cooling performance by disposing a partition plate along the outer periphery of a valve plate, and forming passages inward in sequence in multiple structure when the valve plates are partitioned by the partition plate and the passage is formed. CONSTITUTION:A butterfly valve is provided with hollow valve shafts 6, 7 each having a cooling water passage, which is partitioned by a partition wall 10. On both sides of the valve shafts 6, 7, upper and lower valve plates 2, 3 are disposed opposite to each other with a clearance, which is covered with a casing 1. Numerous partition plates 5 are disposed inside the clearance defined as described above in such a manner that a meandering passage where cooling water flows is formed. Cooling water supplied into the passage formed on the valve shaft 6 flows into the clearance through two openings 8, flows along the meandering passage into the passage inside the valve shaft 7 through openings 9 formed on the valve shaft 7, and then, is discharged through the passage. Consequently, the valve plates 2, 3 can be cooled.
