Problems solved by technology

As a result, sewage with suspended activated sludge is easy to form sludge between the membrane filaments during the process of membrane filtration, resulting in serious pollution of the membrane filaments
Although the flat membrane has advantages over the hollow fiber membrane in terms of anti-high sludge concentration, its filling area is small, and the integrated equipment with the same area has a large size and high maintenance cost

Embodiment Construction

[0015] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0016] Parallel channel membranes such as Figure 1-2 As shown, a plurality of cylindrical channels are arranged in parallel along the same plane, and the plurality of cylindrical channels are wrapped around the outer wall of the separation layer. The number of the plurality of cylindrical channels is 4-10. The cross-sectional outer periphery of the parallel channel membrane is made of straight lines (see figure 1 ) or composed of a round continuous curve with a periodic concave-convex structure (see figure 2 ).

[0017] The parallel channel film is produced through an extrusion die with parallel core liquid (gas) tubes and a common solution (or melt) flow channel outlet. The so...

Abstract

The invention discloses a parallel channel membrane and a parallel channel membrane assembly. The parallel channel membrane is formed by arranging a plurality of cylindrical channels parallelly alongthe same plane, wherein the plurality of cylindrical channels are wrapped with a separation layer outer wall. The parallel channel membrane assembly is formed by arranging a plurality of parallel channel membranes parallelly in a flow channel direction of the membranes, and planes where the parallel channel membranes are arranged also keep parallel arrangement, a casing is arranged outside the parallel channel membranes, and pouring is performed on two ends of the casing. According to the membrane products, sludge deposit between membrane filaments can be avoided effectively, and antifouling property of the membrane products is improved.

Description

technical field [0001] The invention relates to the technical field of water treatment, in particular to a parallel channel external pressure membrane for liquid separation and a membrane assembly thereof. Background technique [0002] The use of membrane technology, especially hollow fiber membrane or flat membrane technology for sewage treatment is the core technology in the field of sewage treatment, and it is also the most widely used technology. For the liquid flow channel, usually the cylindrical flow channel has no dead angle and the flow resistance is small, and the liquid flow is relatively smooth compared with the flow channels of other cross-sections. The main form of conventional cylindrical flow channel external pressure membrane is hollow fiber external pressure membrane, which has been widely used in the fields of environmental protection and water treatment. [0003] In recent years, with the integrated development of membrane technology and other technologi...
