<p>PROBLEM TO BE SOLVED: To generate water flow including fine bubbles sufficiently by constituting a bubble water generator connected to a flow outlet opened into water inside a water jet pump, a bubble container including porous member which is rotatably supported in a water tank, and a compressor for pressing air into the air container. SOLUTION: A duct 2 is suspended downward of a floating body 21 in a horizontal state, and a water jet pump 18 is concentrically arranged inside the duct 2. Water is supplied to the water jet pump 18 by a conveying pump 16 on the floating body 21. A bubble water generator K is connected to a bubble water flow outlet 30 opened to the water jet pump 18 through a leading pipe 29. In the bubble water generator K, compressed air is jetted into water in the water tank 20 from a porous member 3 arranged on the air container 1 into which compressed air is supplied from the compressor 14, the air container 1 is rotated, and thereby, the shearing of the bubble is carried out so as to generate fine bubbles, and then, bubble water is jetted form the water jet pump 18 toward a water region for purifying.</p> |
