摘要： PURPOSE:To increase the rate of settling and to decrease the surface area in a separating part by preparing media having different grain sizes, charging the medium of samllest grain sizes first then increasing stepwise the grain size of the medium to perform in this way a biological treatment of waster water using a fluid medium. CONSTITUTION:In a biological treatment method of a fluid medium type, >=2 kinds of media having different grain sizes, such as sand, active carbon, anthracite, or the like are prepared. A medium of the smallest grain size is charged in the initial period when the operation is started, and when activated sludge sticks to the medium a medium of the grain size larger than the grain sizes charged in the 1st time is charged in the 2nd time. When the activated sludge sticks to these media as well, the media of further larger grain sizes are charged and such operations are repeated plural times, whereby the biological treatment is accomplished. According to the above-mentioned method, the sufficient activated sludge is stuck to the media in about 15-20 days after the start of the operation.

摘要： PURPOSE:To produce a circulating flow of a liquid and contact a gas with the liquid at a high efficiency by a method wherein downwardly extending pipes are connected to a perforated plate provided in the interior of a tank main body and a gas diffuser is provided below the lower openings of the pipes. CONSTITUTION:The perforated plate 3 is fitted in the interior of the tank main body 1, and hollow pipes 5 are connected to the perforated plate 3 in such a manner as not to project above the plate 3. The diffuser 2 is provided in the tank main body 1 below the lower openings of the pipes 5. A gas introduced through the gas diffuser 2 forms gas bubbles, which contact with the liquid and then moves up to a place beneath the perforated plate 3 without entering the pipes 5. Then, the gas bubbles pass through the holes of the plate 3, and after rediffusing, they flow downward into the space below the plate 3 through the pipe 5. Accordingly, since the circulating flows of the gas and the liquid are generated, the efficiency of mixing is enhanced and the mixing time is shortened, resulting in an effective gas passing type agitator.

摘要： PURPOSE:To reduce the installation cost and the running cost of the waste water treatment, by introducing the waste water passed through the anaerobic atmosphere into the aerobic atmosphere parallelly existing in the upper part for the purpose of nitrifying the nitrogen included in the waste water, and by returning the waste water again to the anaerobic atmosphere in order to decompose the nitrated nitrogen. CONSTITUTION:The waste water 18 including nitrogen is introduced from the inlet port 23 into the lower contact basin 2 being kept under the anaerobic condition; after that, the waste water 18 enters into the aerobic contact basin 1 parallelly existing in the upper part through the communicating passage 21; in which, the nitrogen included in the waste water 18 is nitrified to the nitrite or nitrated nitrogen. Next, this waste water 18 flows down through the communicating passage 20 and is returned to the anaerobic contact basin 2. In the anaerobic contact basin 2, the organic substances included in the waste water 18 react on above stated nitrite or nitrated nitrogen and are decomposed to N2 and CO2 gas. In the aerobic contact basin 1, the nitrification reduces the pH; and in the anaerobic contact basin 2, the denitrification raises the pH; since the adjustment of the pH is hus proceeded, the conventional pH modifier can be made unnecessary.
