Embodiment 1

[0029] Refer to Figure 1 ~ Figure 4 , A new type of flexible flat membrane element includes diaphragm 1, diversion net 2 and water production port 3. Among them: diaphragm 1 includes diaphragm one 11 and diaphragm two 12, diversion net 2 includes diversion net 21 and guide Flow net two 22, diaphragm one 11 and diaphragm two 12 are connected and the diversion net 21 and diversion net two 22 are enclosed in diaphragm one 11 and diaphragm two 12, diversion net 21 and diversion net There is a water production port 3 between 22 and 22.

[0030] Combine figure 1 As shown in Fig. 4, the periphery of the diaphragm one 11 and the diaphragm two 12 are heat-sealed and bonded together with a hot-melt adhesive strip 4 of a certain width. Hot melt adhesive has the advantages of smooth surface, soft quality, acid and alkali corrosion resistance, oxidation resistance, etc., which avoids the problem of brittleness and cracking of flat film materials when using conventional adhesives or the temp...

Abstract

The invention discloses a novel flexible flat sheet membrane element which comprises membrane sheets, guide nets and a water generation hole, wherein the membrane sheets comprise a membrane sheet I and a membrane sheet; the guide nets comprise a guide net I and a guide net II; the membrane sheet I and the membrane sheet II are connected to seal the guide net I and the guide net II inside the membrane sheet I and the membrane sheet II; the water generation hole is formed between the guide net I and the guide net II. The invention provides a novel mode for reducing the manufacturing cost and theinvestment cost of flat sheet membranes, and provides the novel flexible flat sheet membrane element which is relatively simple to assemble and relatively low in manufacturing and investment cost.

Description

Technical field [0001] The invention relates to the technical field of membrane filtration and the technical field of sewage treatment, in particular to a new type of flexible flat membrane element, which is generally applicable to the field of membrane filtration, and is particularly suitable for sewage treatment processes. Background technique [0002] Membrane Bioreactor (MBR), as a new and efficient sewage treatment technology, has become an attractive and competitive choice for municipal sewage and industrial wastewater treatment and reuse. Membrane bioreactors are usually composed of membrane modules, aeration modules and power systems. Among them, the membrane module is the most important part of the membrane bioreactor, and the membrane in the membrane module is an indispensable element. At present, there are three types of membrane modules of membrane bioreactors conventionally used, namely hollow fiber membranes, tubular and flat membranes. The flat membrane module was...
