Description

Technical Field

[0001] The utility model relates to the technical field of water treatment, in particular to an elongation-adjustable MBR membrane device. Background Art

[0002] In the MBR process, the curtain membranes of each module are fixedly mounted on a support frame, so the elongation of each module's MBR membrane is fixed. Factors that contribute to sludge accumulation in the MBR membrane include the membrane material, packing density, purge air volume, and elongation. During the actual wastewater treatment process of the MBR process, the position of the curtain membranes is fixed, so their elongation is also fixed. Consequently, when treating different types of wastewater, large amounts of sludge accumulate in the curtain membranes, affecting the wastewater treatment effect. Frequent sludge accumulation in the curtain membranes shortens the cleaning cycle, reduces water production capacity, and increases cleaning costs. Utility Model Content

[0003] In response to the above-mentioned deficiencies in the related prior art, the present application provides an MBR membrane device with adjustable elongation, which can adjust the elongation of the MBR membrane, prevent mud accumulation, extend the service life, and has strong practicality.

[0004] In order to achieve the above purpose, the utility model adopts the following technologies:

[0005] An elongation-adjustable MBR membrane device comprises a support frame and a membrane assembly.

[0006] The membrane assembly includes two brackets that are detachably mounted on a support frame and movable along its length. The height of the brackets is adjustable, and a plurality of connecting pipes arranged at intervals along its length are provided between the two brackets. The connecting pipes are three-way pipes, and the lower ends are connected to a fixed frame, which is installed on the support frame. Telescopic pipes are provided on both sides of the connecting pipes, and one end of the telescopic pipes is connected to the bracket.

[0007] Furthermore, the telescopic tube includes a horizontal section and a vertical section, both of which are provided with a telescopic portion, the horizontal section is connected to the side of the connecting tube, and the vertical section is connected to the bracket.

[0008] Furthermore, the bracket is connected to the support frame through screws, and a plurality of gaskets are provided between the bracket and the support frame, and the gaskets are sleeved on the screws.

[0009] Furthermore, a water outlet is provided on the fixing frame, and an aeration outlet is provided on the supporting frame.

[0010] Furthermore, a plurality of sockets are provided on one side of the bracket along its length direction for placing the MBR membrane.

[0011] The beneficial effect of the utility model is that the elongation of the MBR membrane can be adjusted by the extension and contraction of the telescopic tube and the up and down movement of the bracket, thereby avoiding sludge accumulation, preventing the MBR membrane from quickly accumulating sludge in sewage treatment after the elongation exceeds the design range, and extending the service life.
