Flat sheet membrane supporting plate capable of forming water outlet and circulation channels after being spliced

Abstract

The invention discloses a flat sheet membrane supporting plate capable of forming water outlet and circulation channels after being spliced. A 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 directions of the water outlet pipes are perpendicular to the plate surface of the membrane element supporting plate; a plurality of water outlet holes are formed in the side walls of the water outlet pipes; and a plurality of main water catchment ports for communicating the two sides of the flow guide plate with the water outlet holes are formed in the edge strips; the membrane element supporting plate is a square plate; sealing plates are arranged on two side strips of the square plate; the sealing plates are thicker than the membrane element supporting plate andequal to the water outlet pipe in height; and two side faces of each sealing plate and two ends of the water outlet pipe are located on the same plane. After the membranes are pressed, 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, and assembling is convenient and fast; the membranes and the sealingplates of the membranes are in butt joint to form the side plates, so that a circulation channel is formed between the membranes, and assembling is convenient and fast.

Description

technical field [0001] The invention relates to the field of flat membranes, in particular to a flat membrane support plate which can form water outlet and circulation channels 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...

AI Technical Summary

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, which is time-consuming and laborious. It is easy to fall off; (2) It needs an external slot to be inserted to separate the diaphragm from the diaphragm, which is troublesome to assemble. In order to form a flow channel between the diaphragm and the diaphragm, a sealing plate needs to be installed
