摘要： A water treatment method that uses a reaction tank and involves repeatedly performing an operation cycle including: an inflow step for causing an inflow of waste water; a biological treatment step for subjecting the waste water to biological treatment using biological sludge; a sedimentation step for causing the biological sludge to settle; and a drainage step for draining biologically-treated water that has undergone the aforementioned biological treatment. The reaction tank is provided with an inflow port that is disposed at a position lower than an interface position of a biological sludge bed formed at the bottom of the reaction tank in the sedimentation step, and an inflow pipe that extends upward in the vertical direction from the inflow port. In the inflow step, the waste water is caused to gravitationally flow down in the inflow pipe so as to be fed into the biological sludge bed from the inflow port.

摘要： Provided are a water treatment method and a water treatment device wherein in a biological treatment of ammonium nitrogen-containing water to be treated, the water to be treated can be treated stably at a high treatment speed even when the nitrogen concentration of the water to be treated is high. This water treatment device biologically treats ammonium nitrogen-containing water to be treated. The water treatment device (water treatment method) is provided with: a nitrification device (nitrification step) for oxidizing ammonium nitrogen to nitrite or nitrate nitrogen using nitrifying bacteria including autotrophic ammonia-oxidizing bacteria and nitrite-oxidizing bacteria contained in microbial activated sludge; and a nitrification rate control means which maintains a molybdenum compound in the nitrification device in such a manner as to control the molybdenum concentration of the water to be treated to 0.025 mg Mo/gN or more, and controls the nitrification rate for the sludge to 0.11 [kgN/(kgVSS·day)].

摘要： Provided is a method for producing a chelate resin, wherein a highly pure treatment liquid can be obtained by reducing the amount of metal impurities in a to-be-treated liquid containing metal impurities. The method for producing a chelate resin comprises a purification step for purifying a to-be-purified chelate resin by bringing the chelate resin into contact with at least 5 wt % of a mineral acid solution containing 1 mg/L or less of metal impurities, wherein the total amount of metal impurities eluted when 3 wt % of hydrochloric acid is passed through the purified chelate resin in an amount equal to 25 times the amount of the chelate resin by volume ratio is 5 μm/mL-R or less.

摘要： The water outlet of a subsystem that includes an ultraviolet oxidation device and the water inlet of each substrate treatment device are connected to each other via a main pipe. A hydrogen peroxide removal device is installed between the ultraviolet oxidation device of the subsystem and a non-regenerative ion-exchange device. In addition, a carbon dioxide supply device is installed at the middle of a pipe that branches from the water outlet of the subsystem to reach the substrate treatment device. According to an aspect, the hydrogen peroxide removal device is filled with a platinum-group metal catalyst. Thus, ultrapure water passed through the ultraviolet oxidation device is used as a base to produce carbonated water in which the concentration of hydrogen peroxide dissolved therein is limited to 2 μg/L or less and to which carbon dioxide is added to adjust resistivity to be within the range of 0.03 to 5.0 MΩ·cm.
