Title: Physicochemical treatment of nitrogen-containing waste water
Inventor: NANAUMI TAKUMI
IPC: B01D19/00
Filed: 1999-05-26
Abstract: PROBLEM TO BE SOLVED: To stably remove ammoniacal nitrogen in waste water containing metal components over a long period of time by adjusting the pH of the waste water to a specified range and passing the waste water through a column packed with cation exchange resin particles when the waste water is treated by catalytic wet oxidation treatment. SOLUTION: Waste water in a waste water storage tank 2 is transported by a pump 8 to a pipe 4. During the transport, the pH of the waste water is adjusted to 9-12 by adding an alkali with an alkali adding mechanism 10 to separate metal components in the waste water as hydroxides. The waste water is transported to a column 20 packed with cation exchange resin particles, where the separated metal hydroxides and suspended solids are captured and ionic metal components which remain as metal hydroxides without separating are adsorbed. The waste water is then successively transported to a heat exchanger 6, a heater 12 and an ammoniacal nitrogen removing unit 14, and ammoniacal nitrogen in the waste water is removed. The pressure difference before and after passing the column 2 is measured with a differential pressure gauge 22 and backward washing is carried out, if necessary.

Title: Biosensor and its manufacture
Inventor: FUKUDA YUKIHIRO
IPC: G01N27/28
Filed: 1992-05-12
Abstract: PURPOSE:To obtain a biosensor wherein the responsiveness of a measuring operation in a solution under test can be measured in a short time and to obtain its manufacturing method. CONSTITUTION:A discrimination layer 7 which has carried and held a biological substance is formed in such a way that it is deposited on a partitioned space at the bottom part of a measuring chamber 21. As a result, it can be formed in a prescribed thickness having a small irregularity and in a wide surface area. Since the irregularity in the thickness of the discrimination layer 7 can be reduced, an action pole 5 and a counter pole 15 can be formed at a narrow interval without bringing the discrimination layer 7 into contact with the counter pole 15 when an insulating layer 11 is interposed between the action pole 5 and the counter pole 15 so as to ensure a prescribed distance. Thereby, the line of electric force of an electric double layer which is formed between the action pole 5 and the counter pole 15 can be made short. As a result, a noise current which flows at the early stage of a measuring operation can be converged in a short time, and the measuring time of a substance under test can be shortened.
