<p>An ejector for aeration shown in Fig. 1, wherein a compressor connection part (15) communicating with a compressor is fitted into a small diameter pipe part (11) of a specified length formed so as to restrict the intermediate part of a specified length of a pipe body, a submerged pump delivery port is connected to a connection port (16) formed at one end part of the pipe body, air force-fed from the compressor is jetted to water force-fed from the submerged pump to generate water having a large amount of oxygen dissolved therein and the water is discharged from a discharge port (17) formed at the other end part of the pipe body, and the ratio A/B provided as the ratio of a distance (A) from the edge part of the small diameter pipe part on the discharge port side to the discharge port to a distance (B) from the edge part of the small diameter part on the submerged pump delivery port side to the connection port is set to approx. 0.40 to 0.84, whereby the water having the large amount of oxygen dissolved therein can be efficiently generated.</p> |
