Problems solved by technology

But there are the deficiencies in the following aspects in the flat membrane device of the prior art, one, the height direction of the outlet pipe of the flat membrane in the flat membrane device is parallel to the plate surface direction of the flat membrane support plate, and the flexible pipe is connected on 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. The other is that the hose is easy to age and the third is that the hose is easy to fall off. The membranes are spaced apart, which is troublesome to assemble. In order to form a flow channel between the flat membrane and the flat membrane, a sealing plate needs to be installed

Abstract

The invention discloses a flat sheet membrane device capable of forming water outlet and circulation channels after splicing. The flat sheet membrane device comprises an aeration assembly at the bottom and a plurality of layers of flat sheet membrane assemblies stacked above the aeration assembly; the flat sheet membrane assemblies are limited by a limiting plate at the top of an aeration frame; 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; a plurality of first lugs are arranged at the edge strips of a membrane element supporting plate of the flat sheet membrane; a plurality of water outlet pipes are arranged on the first lugs; sealing plates are arranged at the edge strips on the two sides of the membrane element supporting plate; a water outlet channel is formed after the plurality of flat sheet membranes are overlapped; water outlets communicated with the water outlet channel are formed in the two side plates; a circulation channel with upper and lower openingsis formed between every two adjacent flat sheet membranes; and the upper-layer flat sheet membrane assembly is limited by a limiting plate at the top of the lower-layer flat sheet membrane assembly. The flat sheet membrane device is convenient and fast to assemble.

Description

technical field [0001] The invention relates to the field of flat membranes, in particular to a flat membrane device capable of forming 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. But there are the deficiencies in the following aspects in the flat membrane de...
