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 g/L or less and to which carbon dioxide is added to adjust resistivity to be within the range of 0.03 to 5.0 Mcm.


A non-particulate organic porous material with optical resolution capability, the non-particulate organic porous material having a continuous pore structure, which comprises macropores and mesopores, the macropores being interconnected forming mesopores with a radius of 0.01-100 m in the interconnected parts, and optically active groups uniformly introduced therein possesses high physical stability, can be used under wide separating conditions, and has a large capacity for separating optically active substances (enantiometers).

Provided are a supply apparatus and a supply method for supplying fluid carbon dioxide that are energy-saving and efficient. The supply apparatus for supplying fluid carbon dioxide includes: a circulation system including a purifying unit that removes impurities and contaminants from the carbon dioxide, a storage unit that includes a condenser for changing gaseous carbon dioxide passed through the purifying unit into liquid carbon dioxide, a supply unit that includes a first pump for supplying the liquid carbon dioxide in the storage unit to a use point, and a return line through which excess carbon dioxide supplied from the supply unit but not used at the use point is returned to the storage unit; and a carbon dioxide introduction unit that introduces carbon dioxide, as a starting material or recovered gas, to the circulation system. The carbon dioxide introduction unit includes a second pump for increasing the pressure of the carbon dioxide and the second pump introduces the carbon dioxide to the circulation system.


Treating coal gasification wastewater to remove a cyan compound, a fluorine compound, a selenium compound, ammonia nitrogen and a COD component contained in the coal gasification wastewater to achieve satisfactory quality of treated water, to reduce the content of a toxic substance in produced sludge, and disposes waste materials easily. The system is equipped with a high-temperature alkaline chlorination treatment unit for decomposing at least a cyan compound, ammonia nitrogen and a COD component by such a high-temperature alkaline chlorination treatment that an oxidizing agent is added and the reaction is carried out under warmed conditions; a fluorination treatment unit for removing at least a fluorine compound by a coagulation-sedimentation treatment and/or an adsorption treatment; and a selenium treatment unit for removing a selenium compound that the selenium compound is reduced and then the reduced selenium compound is removed and/or an adsorption treatment.
