HEADER-EQUIPPED AIR DIFFUSION DEVICE, AND MEMBRANE SEPARATION ACTIVATED SLUDGE DEVICE

WIPO Patent Application WO/2019/189183

A1

The purpose of the present invention is to provide a header-equipped air diffusion device which can sufficiently suppress the intrusion of sludge into the air diffusion device from the header and allow stable operation even with repeated operating and stopping, and a membrane separation activated sludge device. The header-equipped air diffusion device (110) comprises an air diffusion device (112) and a header (114) which are immersed in water to be treated. The header (114) includes an air storage unit (140), on the lower end of which is formed an inlet (140a) for the water to be treated, and an air supply part (142) and an air sending part (144) provided on the upper section of the air storage unit (140). The air sending part (144) and a horizontal tube (116) of the air diffusion device (112) are connected, the air sent from the header (114) is diffused by the air diffusion device (112), and an air sending port (144a) of the air sending part (144) in the air storage unit (140) is positioned above an air supply port (142a) of the air supply part (142).
