<p>PURPOSE:To increase the concn. of oxygen in water in a water tank for breading, etc., by treating the hydrogen generated on a cathode plate disposed in the water tank on the outside of the water tank, recovering oxygen by an anode plate, supplying the oxygen to a 2nd water tank and recovering the diffused oxygen. CONSTITUTION:Plates 3, 4 are provided in the water tank 1 and a DC power source 5 is so provided that the plate 3 acts as the cathode and the plate 4 as the anode. Further, a water replenishing pipe 6 is installed. The plate 3 is provided with a hydrogen recovering device 7 to treat the recovered hydrogen on the outside of the water tank 1. The plate 4 is provided with an oxygen recovering device 8 and an oxygen piping 11 is installed from an air pump 10 down to the bottom of the water tank 2 to release the oxygen into the water in the tank 2. An oxygen recovering device 9 is provided in the perpendicular upper part of the oxygen supply port of the piping 11 to recover the oxygen diffused in the air in the oxygen released into the water. The recovered oxygen is reutilized. The concn. of the oxygen in the water in the tank 2 is increased in this way and the growth of living things is assisted.</p> |
