<p>PURPOSE:To contrive an improvement of water quality through prevention of oxygen deficiency by arranging diffuser pipes in an underwater construction, wherein underwater inhabitants live, installing a blower and a solar power generation equipment at a site above the water and sending air to the diffuser pipes so as to aerate the inside of underwater construction. CONSTITUTION:A porous underwater construction 80, wherein underwater inhabitants live, is arranged under the water and quipped with diffuser pipes 10 in it. Furthermore, a solar power generation equipment consisting of solar panels 30 is installed as a power source of a blower 20, which is connected to the diffuser pipes 10 by an air hose 40. The air, which is ejected from the diffuser pipes 10 by driving the blower 20, passes through clearances of the porous underwater construction 80 and makes a surrounding environment aerobic. An environment of good water quality is, therefore, formed through promoted decomposition of egesta by air bubbles, promoted rate of organic substance incorporation by living things adhering to the underwater construction 80 and food chains.</p> |
