Description

Technical Field

[0001] The utility model belongs to the technical field of membrane bioreactors, in particular to a membrane stack water collecting pipe. Background Art

[0002] The submerged membrane bioreactor (MBR) is an organic combination of membrane separation technology and biotechnology. It uses ultrafiltration or microfiltration membrane separation technology to replace the secondary sedimentation tank and conventional filtration unit of the traditional activated sludge method, so that the hydraulic retention time (HRT) and sludge age (STR) are completely separated. This is an efficient and economical sewage resource technology with efficient solid-liquid separation capabilities. Not only is the effluent water quality good, the suspended solids and turbidity are close to zero, but it can also intercept biological pollutants such as Escherichia coli. And because the effluent water quality is significantly better than the traditional sewage treatment process, the treated water can be directly reused, and it has a wide range of application prospects.

[0003] The existing standard modular membrane module has a stainless steel bracket and two membrane stacks installed therein in an integrated manner. The membrane stack water collecting pipe connecting each diaphragm in the membrane stack is welded to the water collecting pipe of the stainless steel bracket. The integrated installation is not conducive to the integration of the membrane module, and the installation work is cumbersome and the installation efficiency is low. A long water collecting trough is axially arranged on the outer wall of the membrane stack water collecting pipe, which is connected to each diaphragm through the water collecting trough to collect the water produced by the diaphragm. The sealing effect between the long water collecting trough and the diaphragm is not good, which affects the sealing performance.

[0004] Therefore, it is necessary to provide a membrane stack water collecting pipe to solve or at least partially solve the above problems. Utility Model Content
