Claims (1)

[Claims for Utility Model Registration] 1. A biological reaction tank in which a large number of tubular filtration membranes 3 are arranged in parallel, with the inlet/outlet 10 of the filtration membranes 3 in an open state at the upper part, and an aeration device 1 at the lower part. 2, the filtration membrane group 3 is composed of a plurality of membrane modules 5 stacked vertically on a pedestal 12, and the aeration A substantially cylindrical first guide wall 13 for guiding air bubbles from the device 1 to the membrane module 5 at the lowermost portion is provided on the periphery of the pedestal 12 to guide the air bubbles to the membrane module 5 adjacent to the upper part. A substantially cylindrical second guide wall 14 for guiding is provided around the periphery of the membrane module 5, and is formed to have a vertical length such that when the membrane modules 5 are stacked vertically, adjacent ones are substantially in communication with each other. Membrane built-in microbial treatment or solid-liquid separation equipment. 2 A built-in membrane structure in which a large number of tubular filtration membranes 3 arranged in parallel are immersed in the liquid of a biological reaction tank 2, which has an inlet/outlet port 10 for the filtration membranes 3 in the upper part and an aeration device 1 in the lower part. type microorganism treatment or solid-liquid separation device, in which the three groups of filtration membranes are mounted on a pedestal 1.
It is composed of a plurality of membrane modules 5 stacked vertically on top of each other, and guides air bubbles from the aeration device 1 to the lowest membrane module 5. A first guide wall 13 is provided on almost the entire circumference of the pedestal 12, and a second guide wall 14 for guiding the air bubbles to the membrane module 5 adjacent to the upper part is provided on the upper part closer to the center of the membrane module 5. A device for microbial treatment or solid-liquid separation with a built-in membrane, which is provided around the membrane module 5 so as to be inclined to the side. 3. The membrane built-in type for microbial treatment according to claim 1 or 2, wherein the laminated membrane modules 5 are arranged in parallel in the horizontal direction in a state where a large number of the membrane modules 5 are immersed in the liquid of the biological reaction tank 2.
