Technical Field

[0001] The utility model relates to the technical field of sewage treatment, in particular to a sewage membrane treatment device. Background Technique

[0002] In the application number: CN201920335622.8, an integrated high-efficiency sewage membrane treatment device is disclosed, which realizes that the sewage treatment device can switch to a suitable treatment mode according to the sewage quality for sewage treatment, ensuring the treatment efficiency as much as possible and reducing the energy consumption of the sewage treatment device and the loss of treatment agents. However, the above design still has deficiencies. The device discharges sewage into the device through the water inlet pipe, but the water inlet pipe has a single function problem and cannot pre-treat the sewage. During the use of the water inlet pipe, impurities in the sewage will adhere to the inner wall. With the long-term use of the device, the impurities on the inner wall of the water inlet pipe will accumulate, which will affect the flow rate of the water inlet pipe and reduce the working efficiency of the device.

[0003] Therefore, we propose a sewage membrane treatment device. Content of the Utility Model
