PURPOSE:To enhance the dissolving efficiency of oxygen, by providing a jet stream generator injecting gas and a liquid from an external nozzle and a tubular flow distributor emitting the air bubble-containing stream injected from the external nozzle while mixing the same with peripheral water. CONSTITUTION:A jet stream generator 1 is constituted by arranging a fluid inlet 1, a gas inlet 4, an external nozzle 5, an internal nozzle 6 and a grinding means 7. The internal nozzle 6 and the grinding means 7 are present in the jet stream generator 1. A gas-liquid mixing apparatus is constituted of the jet stream generator 1 and the flow distributor 2. The flow distributor 2 is composed of a pipe opened at both ends thereof and the inner diameter thereof is largest at the inlet 9 thereof and gradually decreases at least up to the midway thereof from the inlet 9 toward the discharge port 10 thereof. Since the blow distributor has this configuration, even when the mixing ratio of gas/liquid of an air bubble-containing stream is increased to 2/1-3/1, the unification of air bubbles is not generated and a finely divided state of air bubbles can be held. |
