The invention provides an axial-flow coaxial membrane tube microbubble uniform mixing device which is used for floatation treatment of oily sewage and industrial wastewater. By adopting the coaxial membrane tube/electric-drive multistage-series helical blade special structure, the axial-flow coaxial membrane tube microbubble uniform mixing device implements organic combination of the microporous cyclone foaming and bubble crushing pressurized uniform mixing technique. The membrane tube assembly completes microporous cyclone primary foaming and generates a microbubble-carrying two-phase flow, and the large-diameter membrane tube is combined with the cyclone teeth and high-speed rotating blades, thereby increasing the foaming area of the rotating liquid flow, enhancing the utilization ratio of the floatation gas and implementing the membrane tube inside/outside bidirectional jet high-efficiency foaming. The pressurized uniform mixer completes axial-flow crushing secondary foaming and generates a small-particle-size bubble flow, the multistage-series helical blades shear and crush the bubbles, and the mixing uniformity between the microbubbles and sewage is high, thereby simultaneously implementing the functions of bubble spiral pressurization and self-cooling. The foaming uniform mixing control system remotely and automatically controls the floatation gas flow rate in the gas supply manifold, the sewage flow rate in the liquid supply manifold and the rotating speed of the variable-frequency motor.
