Flat sheet membrane supporting screen plate capable of forming water outlet channel after being spliced

Abstract

The invention discloses a flat sheet membrane supporting screen plate capable of forming a water outlet channel after being spliced. The flat sheet membrane supporting screen plate comprises a membrane element support plate; the membrane element supporting plate comprises peripheral edge strips and a flow guide plate positioned in the edge strips; a plurality of lugs are arranged at the edge strips of the membrane element supporting plate; a plurality of water outlet pipes are arranged on the lugs; the height direction of the water outlet pipes is perpendicular to the plate surface of the membrane element supporting plate; the height of the water outlet pipes is larger than the thickness of the membrane element supporting plate; a plurality of water outlet holes are formed in the side walls of the water outlet pipes; a plurality of main water catchment openings for communicating the two sides of the flow guide plate with the water outlet holes are formed in the edge strips; and the flow guide plate is of a screen plate structure. After a plurality of membranes are overlapped, the water outlet pipes of the membranes are communicated to form a water outlet channel, a hose does not need to be connected in a sleeved mode, assembling is convenient and fast, the membranes are spaced through the spacing strips and then pressed, and the situations of falling off, aging and the like areavoided. The flow guide plate is changed into a screen plate structure, so that the cost is effectively reduced, and the water catchment flux of the membrane is increased.

Description

technical field [0001] The invention relates to the field of flat membranes, in particular to a flat membrane support screen capable of forming a water outlet channel after splicing. Background technique [0002] Membrane bioreactor (MBR), as a practical sewage advanced treatment technology, has obvious technical advantages compared with traditional biochemical technology, and has a broad market and development space. MBR is a new type of water treatment technology that combines membrane separation unit and biological treatment unit. It replaces the secondary settling tank at the end of traditional biological treatment technology with membrane modules, maintains high active sludge concentration in the bioreactor, and improves biological treatment. load, thereby reducing the footprint of the sewage treatment facility, and reducing the amount of excess sludge by keeping the sludge load low. The flat membrane element is an important core component in the MBR membrane bioreacto...

Problems solved by technology

The flat membrane element is an important core component in the MBR membrane bioreactor, and the support plate is an important core component of the flat membrane element. The flat membrane in the current technology has the following deficiencies: (1) The height direction of the outlet pipe and the flat plate The direction of the surface of the membrane support plate is parallel, and the hose is connected to the outlet pipe to collect the outlet water. There are several problems in the hose connection. One is that it is inconvenient to insert and connect, and it takes time and effort. The tube is easy to fall off; (2) The support plate is thick, and the support plate constitutes the main cost structure of the membrane element, resulting in high cost of the membrane element and low water catchment flux of the membrane
