摘要： PROBLEM TO BE SOLVED: To provide a water purifier capable of preventing algae from growing in a water tank. SOLUTION: A water purifier D1 comprises a water tank, a filtration tank 30, a water receiving tank 2, a filtration tank 3, a decolorization tank 10, a pair of electrodes 4, 4, a direct-current power supply, a suction pipe 6, a circulation pump 7, and a return pipe 12. The iron ions eluted to a water receiving tank 2 by electrolysis react with phosphoric acid in water to produce water- insoluble phosphorus compounds, which are flocculated. A part of the flocculated water-insoluble phosphorus compounds floats on water, and the other part precipitates and accumulates in the water receiving tank 2. A control part 20 has a normal electrolysis mode to carry out control of drive of a circulation pump 7 and of a blower 18 and to perform electrolysis at a prescribed current value, and a strong electrolysis mode to carry out electrolysis at a prescribed current value higher than that of the normal electrolysis mode, and it controls the electrolysis in the water receiving tank 2.

摘要： PROBLEM TO BE SOLVED: To prevent that hydrogen gas generated from an electrode is stored in an elution tank to generate explosion by providing an air diffusion pipe aerating sewage in the elution tank in the elution tank above a discharge port and controlling the supply amt. of sewage by a supply means so as to reduce the same. SOLUTION: A control circuit stops a third blower 35 until a first air diffusion pipe 14 is exposed at every definite time to stop the new supply of sewage to an elution tank 8. Therefore, by exposing the first air diffusion pipe 14 at every definite time from sewage to reduce the water pressure to the first air diffusion pipe 14, the amt. of air supplied from a first blower 15 through the first air diffusion pipe 14 increases. Therefore, without increasing the amt. of air of the first blower 15, hydrogen gas generated from an electrode 12 by the electrolysis of an electrode 12 can be forcibly discharged from an exhaust port by the air supplied from the first air diffusion pipe 14 and a rise in the concn. of the hydrogen gas in the elution pipe 8 is prevented to prevent explosion.
