Abstract
The invention discloses a method for maintaining activity of an electrolytic ozone generator. The electrolytic ozone generator comprises an ozone generator, a deionized water tank and an air/water mixing device. A communicating pipe, an ozone water outlet pipe and a tap water inlet pipe are all provided with control solenoid valves. All the control solenoid valves form a machine control system. The method is characterized in that when the machine control system works, a direct current power supply (1) supplies control current to the control solenoid valves; a direct current power supply (2) supplies full-loaded membrane electrode working current to the ozone generator; and when the machine control system stops working or does not work, the direct current power supply (1) stops outputting current and the direct current power supply (2) continually supplies membrane electrode afterflow current less than the membrane electrode working current to the ozone generator. In the method, different direct current power supplies are used for respectively supplying power to the machine control system and the membrane electrode of the electrolytic ozone generator to maintain the membrane electrode system of the electrolytic ozone generator in high activity state all the time so that the ozone generator gives play to high performance immediately after being used at any time and further generates high yield ozone immediately after being started.
