PURPOSE:To purify the seawater in a water tank and to obtain the seawater adequate for the breeding of the sea bream and flatfish by arranging the ozone purification reaction part and activated carbon-bed adsorption part in the same vessel and passing the seawater in a water tank successively through a filter, the ozone purification reaction part and the activated carbon-bed adsorption part and returning the purified seawater to the water tank. CONSTITUTION:An inner case 2 is provided in a vessel 1, an ozone purification reaction part 3 is formed, an activated carbon-bed adsorption part 4 is furnished between the inner case 2 and the vessel 1, and the lower part of the vessel 1 is communicated with the lower part of the inner case 2 through a communicating hole 5. The seawater sucked up from the water tank 12 such as a seawater fish farm by a suction pump 6 is filtered by an automatic backwashing- type filter 7, absorbs ozone gas supplied from an ozonizer 9 and is introduced into the reaction part 3. The seawater introduced into the reaction part 3 is allowed to flow into the adsorption part 4, oozed out into the space 31 between the upper presser net 20 and upper lid 30, and returned to the water tank 12 through a water pipeline 22 of the side wall of the vessel 1. |
