Description

Technical Field

[0001] The utility model relates to the technical field of MBR membrane bioreactors, in particular to an MBR membrane bioreactor which is easy to assemble. Background Art

[0002] MBR membrane bioreactor is a new type of wastewater treatment system that organically combines membrane separation technology and biological treatment technology. It uses membrane components to replace the terminal secondary sedimentation tank of traditional biological treatment technology, maintains a high activated sludge concentration in the bioreactor, and increases the organic load of biological treatment, thereby reducing the footprint of sewage treatment facilities. It also reduces the amount of residual sludge by maintaining a low sludge load. It mainly utilizes the activated sludge and macromolecular organic matter in the retention tank of the membrane separation equipment immersed in the aerobic biological pool.

[0003] When installing the existing MBR membrane bioreactor, since the exposure component and the membrane installation component are a whole, multiple workers and multiple sets of machinery are needed to complete the installation work, and the work efficiency is also low. After installation, the current device is not convenient for removing and replacing the MBR membrane, which reduces the applicability of the device. Therefore, it is necessary to improve the existing device to meet actual needs. Utility Model Content
