SUBMERGED COMBINED AERATOR

摘要

PROBLEM TO BE SOLVED: To provide a submerged combined aerator effectively agitating surface layer water to uniformize water temperature and to inhibit the growth of algae, even if surplus air accumulated in an air sump chamber in an aerator body is non-compressed air.

SOLUTION: An air diffusion pipe 27 having an exhaustion control valve (float valve 33C) is provided on the aerator body 24 moored on the bottom 1 of a dam lake or the like and circulating bottom layer water near the bottom 1 by aeration. The submerged combined aerator 22 is configured such that the air diffusion pipe 27 diffuses the surplus water d accumulated in the air sump chamber 10 in the aerator body 24 into the water to agitate the surface layer water. The air diffusion pipe 27 is provided with fragmentation members 38A-38D fragmenting air lump of the non-compressed surplus air d discharged into the water from the air diffusion pipe 27.
