    摘要: Deionized water from a deionized water source (21) for electrolysis is supplied by a pressurizing pump (20) to an electrolyzer (2) to obtain a hydrogen gas and ozone gas by means of electrolysis. The pressures of these gasses are maintained at not less than the atmospheric pressure. These gasses at a pressure of the atmospheric pressure or more are dissolved in high-purity water in gas dissolving units (6,7) to obtain ozone water and hydrogen water respectively. These ozone water and hydrogen water are introduced into mixer (8,9) to adjust pH respectively. In this way, highly-concentrated, gas dissolved cleaning solution is prepared in a short period of time.
