WATER AREA PURIFYING DEVICE

摘要

PROBLEM TO BE SOLVED: To remarkably accelerate a purification of the water area in a water area purifying device. SOLUTION: A water intake mechanism 1 intaking the water in the water area an air intake mechanism 4 intaking air, a nitrogen adsorbing implement 5 removing the nitrogen from the air intaken by the air intake mechanism 4 and an aqueous stream generating machine 7 mixing the water intaken by the water intake mechanism 1 and the air from which the nitrogen is removed by the nitrogen adsorbing implement 5 and injecting the resulting mixture into the water area are provided to increase a dissolved oxygen amount in the water injected into the water area from the aqueous stream generating machine 7. Moreover, the purification of the water in the water area is accelerated by using a permeable pipe 9 made of an oxygen molecule permeable membrane or a UV-ozone pipe or a titanium oxide pipe together with the nitrogen adsorbing implement 5 or the instead of the nitrogen adsorbing implement 5.
