Description

Technical Field

[0001] The utility model relates to the technical field of MBR sewage treatment, in particular to an MBR sewage treatment device. Background Art

[0002] MBR sewage treatment is a common method of modern sewage treatment. It uses membrane bioreactor technology, which is a new technology that combines biological treatment technology with membrane separation technology. It replaces the secondary sedimentation tank in traditional processes. It can efficiently separate solids and liquids and obtain stable reclaimed water for direct use. An MBR sewage treatment device is now needed.

[0003] During the use of existing MBR sewage treatment equipment, the early filtration effect of sewage is generally poor, resulting in membrane fouling of the organic matter and sludge in the sewage on the MBR membrane, which affects the MBR membrane's purification of sewage and the sewage treatment effect. At the same time, the MBR membrane in the equipment needs to be cleaned after membrane fouling. In addition, existing sewage treatment devices have some shortcomings to a certain extent. The sewage contains some garbage and impurities. Existing sewage treatment devices usually do not have the function of collecting and filtering garbage and impurities in the sewage during use, which reduces the sewage treatment effect of the sewage treatment device. The sewage treatment device needs to replace the MBR flat membrane during use. The existing sewage treatment device is not convenient to replace the MBR flat membrane, which makes the sewage treatment device unable to guarantee the sewage treatment effect. The sewage treatment device has high requirements for the sealing performance between the outlet pipe and the pipe body during use. The existing sewage treatment device does not have good sealing performance between the outlet pipe and the pipe body during use. This easily leads to the phenomenon of treated reclaimed water leaking from between the outlet pipe and the pipe body during use of the sewage treatment device, which reduces the sealing effect of the sewage treatment device during use.
