摘要： PROBLEM TO BE SOLVED: To provide a sterilizing device for toilet stool flushing water which has a function of preventing the sticking of fur and slime to a flush toilet stool and occurrence of odor and which is also easy to fit and does not require labor for replacement. SOLUTION: A water storing part of a flush tank is provided with at least one pair of electrodes 6a and 6b at least one of which is a silver one. By impressing the silver electrode used as an anode, therefore, a current flows between the electrodes and silver ions dissolve from the silver electrode being the anode and are supplied into toilet stool flushing water. Since the toilet stool flushing water being present in the flush tank 22 and containing the silver ions is supplied to a flush toilet stool 1 after the flush toilet stool 1 is used, the toilet stool flushing water containing the silver ions stay in a trap part of the flush toilet stool 1 after filth is flushed away. According to this constitution, the inside of the flush toilet stool is sterilized by the silver ions and sticking of fur and slime due to propagation of miscellaneous bacteria and the consequent of occurrence of odor can be prevented.

摘要： PURPOSE:To enhance the efficiency of regenerating the active carbon of the water purifier of an active carbon cartridge type. CONSTITUTION:After all valves are closed, the valve 7a is opened to discharge the water remaining in the cartridge 2 and thereafter, the pressure in the cartridge 2 is reduced by closing the valve 7a and opening the valve 8a. The low boiling point org. matter, such as trihalomethane, adsorbed on the active carbon 4 is then desorbed. The active carbon restores the ability to adsorb the trihalomethane, etc., again and the regeneration is finished.
