The present invention relates to a membrane filtration bioreactor including a floating gas collector being used for advanced treatment in a wastewater treatment plant etc. A problem to be solved is to provide a membrane filtration bioreactor including an improved floating gas collector which can automatically react to the water surface fluctuation of a membrane filtration bioreactor tank, prevents the generation of scum, facilitates gas discharge, and generates complete mixture in the membrane filtration reactor tank. A solution to the problem is to form a reverse U-shaped water flow path by installing a gas capture tub (60) connected to a buoy at the upper part of the membrane filtration bioreactor tank and a guide water flow path (35) and to compose the membrane filtration bioreactor by installing a degassing unit. The present invention stably controls the concentration of dissolved oxygen by automatically raising and lowering the gas capture tub in case of the water surface fluctuation of the membrane filtration bioreactor tank and improves the effects of advanced treatment by preventing the generation of scum with flow on a water surface, facilitating the charge of carbonic acid gas, and generating complete mixture in the whole membrane filtration reactor tank, thereby improving effluent water quality and facilitating maintenance.
