The invention provides an air diffusion header, an air diffusion apparatus, a membrane module unit and a water treatment method. The air diffusion header is easy to assemble, and can be flexibly adjusted in length in accordance with the number of membrane modules and highly precisely connected with air diffusion branches. The air diffusion header (4) is used for supplying air for air diffusion foran air diffusion branch (5) for washing a membrane assembly for water treatment. The air diffusion header (4) comprises multiple cylinder parts (41). The cylinder parts (41) comprise cylinder main bodies (42), wherein the end part (42a) of at least one of the cylinder main body is opened. The cylinder parts (41) are mutually connected successively in an airtightness manner through the end parts (42a) of the cylinder main bodies (42). At least one cylinder part (41) in the cylinder parts (41) comprises a connection part (45) which is connected with the air diffusion branch (5) and used for supplying air for air diffusion to the air diffusion branch (5). At least one cylinder part (41) of the cylinder parts (41) comprises a supplying opening (43) for supplying air for air diffusion to the interior of the cylinder main body (42).
Description
technical field [0001] The invention relates to an air diffuser main pipe, an air diffuser, a membrane module and a water treatment method. Background technique [0002] In water treatment such as water purification and wastewater treatment, various methods of solid-liquid separation of water to be treated are being studied using membrane modules equipped with separation membranes such as microfiltration membranes and ultrafiltration membranes. High-quality treated water can be obtained by filtering the water to be treated using a membrane module equipped with a separation membrane. As a method of performing solid-liquid separation of water to be treated using such a membrane module, for example, a method of performing solid-liquid separation using a hollow fiber membrane module in which a plurality of hollow fiber membranes are fixed in a sheet shape is known. In addition, a method is known in which a plurality of membrane modules are connected to a cylindrical water colle...
