INJECTION DEVICE OF SODIUM HYPOCHLORITE

摘要

PROBLEM TO BE SOLVED: To provide an injection device of sodium hypochlorite so as to exhibit bactericidal effect especially against viruses, etc., even by a low concentration and capable of aiming at the effective regeneration of using water in fishery used water. SOLUTION: This injection device of sodium hypochlorite equipped with a stock liquid injection pump 4 for feeding the stock liquid to a sodium hypochlorite-added liquid preparation tank 2 from a sodium hypochlorite stock liquid tank 1, and a prepared liquid injection pump 5 for injecting the sodium hypochlorite-prepared liquid into using water is provide by setting so that light from a light source 3 is irradiated to the prepared liquid of sodium hypochlorite in the sodium hypochlorite-added liquid preparation tank 2 and also installing a sodium hypochlorite prepared liquid-bypassing passage at the sodium hypochlorite-added liquid preparation tank 2 so as to circulate the sodium hypochlorite-prepared liquid while irradiating the light.
