Document Type and Number:
Japanese Patent JP6938349
Kind Code:
B2
Abstract:
To provide a siphon type air diffusion pipe which can adjust a size and an intermittent time of air bubbles, a membrane separation activated sludge device, and a water treatment method.SOLUTION: A siphon type air diffusion pipe 1 comprising a housing 50 which is provided with an upper wall 1A, a side wall 1B and a bottom wall 1C so that a space is formed in the interior of the housing, and a first partition wall 4a and a second partition wall 4b which are provided at an interval so that faces of both walls face each other, and partition the space in the housing 50. A space from a lower end 4aof the first partition wall 4a to an upper end 4bof the second partition wall 4b on a treatment water inflow port 7 side with respect to the first partition wall 4a in the housing 50 becomes a siphon chamber 2, any or both of the first partition wall 4a and the second partition wall 4b, and the housing 50 are relatively moved in a vertical direction, whereby a volume of the siphon chamber 2 is changed.SELECTED DRAWING: Figure 3
