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

Abstract

The invention discloses a flat sheet membrane assembly capable of forming water outlet and circulation channels after splicing. The flat sheet membrane assembly comprises two side plates and a plurality of limiting strips for connecting the two side plates; a plurality of flat sheet membranes are clamped between the two side plates; the two side plates are connected through a tensioning rod; the flat sheet membrane comprises a membrane element support plate, flow guide cloth and a filter membrane; the flow guide cloth and the filter membrane are positioned on two sides of the membrane elementsupport plate; the membrane element support plate comprises peripheral edge strips and flow guide plates positioned in the edge strips; a plurality of first lugs are arranged at the edge strips of themembrane element support plate; a plurality of water outlet pipes are arranged on the first lugs; sealing plates are arranged on two side strips of the membrane element supporting plate; water outletpipes of the flat sheet membranes form a water outlet channel after the flat sheet membranes are overlapped; and water outlets communicated with the water outlet channel are formed in the two side plates. According to the flat sheet membrane assembly, the plurality of flat sheet membranes are superposed and assembled to form the water outlet channel and the circulation channel, so that the assembly is convenient and fast, and side plates and hoses are not needed.

Description

technical field [0001] The invention relates to the field of flat membranes, in particular to a flat membrane module 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. However, the flat membrane module in the prior art has the deficiencies in the foll...

Problems solved by technology

However, the flat membrane module in the prior art has the deficiencies in the following aspects. One, the height direction of the outlet pipe of the flat membrane in the flat membrane module is parallel to the direction of the plate surface of the flat membrane support plate, and the hose is connected to the outlet pipe to There are several problems in the connection of the hose when the water is collected. One is that it is inconvenient to insert and connect, which is time-consuming and laborious. On the other hand, the hose is easy to age. The third is that the hose is easy to fall off; The flat membranes are spaced apart, which is troublesome to assemble. In order to form a flow channel between the flat membranes and the flat membranes, it is necessary to set up a sealing plate
