摘要： PROBLEM TO BE SOLVED: To suppress the formation of an instable main stream part by minute turbulence to obtain an excellent cleaning effect of a membrane element. SOLUTION: In a biological treatment tank 1 filled with an active sludge mixture liquid 11, a membrane unit 2 composed of a plurality of membrane elements 21 having a filtration action is immersed, and an aeration tube 4 is provided below it. Air supplied from an aeration blower 5 is discharged as bubbles 12 from the aeration tube 4, and the discharged bubbles 12 form an elevating flow, pass through a flow speed adjuster 3 and flow into the inter-membrane flow path 22 of the membrane unit 2. A recessed part in an inverse chevron shape or a chevron shape is provided on the upper side or lower side of the flow speed adjuster 3, and the flow path resistance of a center part is small. Thus, a flow speed at the center part of the inter-membrane flow path 22 becomes high, and a stable main stream part is formed at the center part of the inter-membrane flow path 22. Since the bubbles 12 of the stable main stream part act on the membrane elements 21, the deposition of active sludge is prevented, and the formation of the instable main stream part is suppressed.
