Embodiment 1

[0030] like Figure 1-5 As shown, a combined MBR membrane structure for sewage treatment includes two upper and lower aeration shells 1, at least one roll-type MBR membrane structure 2 detachably installed between the two aeration shells 1, and two aeration shells. The aeration system 3 communicated with the air shell 1.

[0031] The rolled MBR membrane structure 2 includes a fixing strip 21, membrane fibers 22 and aeration strips 23. The membrane fibers 22 are evenly distributed in a row and both ends are clamped and fixed by the fixing strips 21 and the aeration strips 23 to obtain a strip. MBR membrane structure, the strip-shaped MBR membrane structure is wound along the length direction of the fixed strip 21 to obtain a rolled MBR membrane structure 2, and the wound aeration strip 23 is communicated with the aeration system 3 through the aeration shell 1, and the aeration system 3 is For the blower and the air pipeline connected to the aeration shell 1 , after the strip-s...

Embodiment 2

[0045] like Image 6 As shown, this embodiment is basically the same as Embodiment 1, the difference is that the inner cavity of the fixing bar 21 is hollow, the fixing bar 21 is provided with an inflation port 4, and a sealing plug is clamped at the inflation port 4.

[0046] When the fixing strip 21 is a rubber airbag, after installing the rolled MBR film structure 2 in the card slot 5, the rubber airbag can be inflated through the inflation port 4 to make it bulge to fill the gap of the card slot 5, the winding gap, etc. To avoid water leakage from gaps, the rolled MBR membrane structure 2 can be tightly connected with the aeration shell 1 .

[0047] In addition, in order to ensure the connection strength between the roll-type MBR membrane structure 2 and the aeration shell 1 , after the roll-type MBR membrane structure 2 is clamped into the clamping slot 5 , a glue sealing process can be performed.

Abstract

The invention relates to a combined MBR membrane structure for sewage treatment. The combined MBR membrane structure comprises an upper aeration shell, a lower aeration shell, at least one roll type MBR membrane structure detachably mounted between the two aeration shells, and an aeration system communicated with the two aeration shells, the roll type MBR membrane structure comprises a fixed strip, membrane fibers and an aeration strip, the membrane fibers are uniformly distributed into a row, two ends of the membrane fibers are clamped and fixed by the fixed strip and the aeration strip to obtain a strip-shaped MBR membrane structure, the strip-shaped MBR membrane structure is wound along the length direction of the fixed strip to obtain the roll type MBR membrane structure, and the wound aeration strip is communicated with the aeration system through the aeration shell. The spiral-wound MBR membrane structure and the aeration shell are combined into a whole and correspond to each other, and the aeration shell is connected with the aeration system, so that the combined MBR membrane structure which not only has the purification function of an MBR membrane, but also has the aeration self-cleaning function can be obtained, two-step installation is not needed, and the combined MBR membrane structure is simple in structure, convenient to assemble and disassemble, economical and practical.

Description

technical field [0001] The invention belongs to the technical field of sewage treatment, and in particular relates to a combined MBR membrane structure for sewage treatment. Background technique [0002] MBR (Membrane Bioreactor) process is a new type of water treatment technology that combines activated sludge process and membrane separation technology. According to the structure type of membrane, there are flat type, tube type, spiral type and hollow fiber type. Flat membrane or hollow fiber membrane modules need aeration at the bottom of the membrane modules during operation. In addition to the basic function of supplying oxygen to the microorganisms in the biological reaction tank, the membrane module aeration system is also an effective means to control membrane fouling. By using the gas-liquid two-phase flow generated by the aeration at the lower part of the membrane module to provide scouring on the membrane surface, the sludge adsorbed on the surface of the membran...
