PROBLEM TO BE SOLVED: To provide a technology for stably and safely deodorizing, decolorizing and sterilizing water, concretely, a technology for deodorizing, decolorizing and sterilizing raw water for purifying water or wastewater for detoxifying, producing water suited for drinking in case of purified water, and safely discharging to rivers in case of wastewater. SOLUTION: In this method, the liquid obtained by the electrolysis of hydrochloric acid in a non-diaphragm electrolysis cell is continuously injected to raw water. Since the non-diaphragm electrolysis cell is used, the clogging and consumption of the diaphragm do not occur, and also since the electrolyte is acidic, the deposition of scale to a cathode does not occur, thereby stably and continuously obtaining the liquid high in deodorizing, decolorizing and sterilizing effects. Also, since the produced liquid can be made into an optional acidity, it is possible to prevent the liquid from becoming alkaline when being mixed with the water to be treated, so that there is a merit having no possibility of producing trihalomethane.
