Embodiment Construction

[0044] The following combination image 3 and Figure 4 , the structure of the flat-plate membrane filter element of the present invention will be described.

[0045] The present invention provides a flat-plate membrane filter element 2 , which has a membrane support 21 and a non-woven fabric membrane 22 . The membrane support 21 is in the shape of a flat plate, and the surface of the membrane support 21 has flow channels 24 distributed in a serpentine shape. The non-woven membranes 22 are respectively located on the surface of the membrane supports 21, and the non-woven membranes 22 are bonded to the membrane supports 21 by the edges around them to cover the serpentine distribution channels 24 on the membrane supports 21 on the non-woven membranes. Under the cloth membrane 22. There is a protruding structure 23 in the area where the surface of the membrane support 21 is covered by the non-woven membrane 22, and the protruding structure is used to prevent the non-woven memb...

Abstract

The invention relates to a flat-type membrane filtration element and a manufacturing method thereof, a flat-type membrane filtration assembly and a membrane bioreactor. The flat-type membrane filtration element comprises a membrane support member in the shape of a flat plate, each surface of the membrane support member is provided with a snakelike flow channel, and two end openings of each flow channel are at one side of the membrane support element; non-woven fabric membranes are disposed at the upper and lower surfaces of the membrane support member, the periphery of each non-woven fabric membrane is bonded to the membrane support member for covering the flow channels on the membrane support member; and a water outlet pipe is communicated with the openings at two ends of the flow channel. The flat-type membrane filter element is high in strength, long in service life, easy to manufacture and high in filtering efficiency.

Description

technical field [0001] The invention relates to a membrane filter element, in particular to a flat membrane filter element for sewage purification and a manufacturing method thereof, as well as a flat membrane filter assembly and a membrane bioreactor comprising the membrane filter element. Background technique [0002] At present, the biochemical treatment process is widely used in the field of sewage purification, and the pollutants in the sewage are removed through the biochemical reaction of microorganisms. Membrane bioreactor, as an emerging water treatment technology, can combine biological treatment and membrane separation process to treat sewage. Such as figure 1 As shown, the purification system 1 of the prior art generally consists of a water inlet part 11, a reaction part 12 and a water outlet part 13, and the reaction part 12 is usually provided with a non-woven membrane reaction tank 14, and the non-woven membrane reaction tank 14 has a The aeration device 15 ...
