Abstract

The invention discloses a membrane separation device which comprises a plurality of membrane assemblies arranged side by side, each membrane assembly comprises a membrane and water collecting pipes arranged at the two ends of the membrane respectively, the membranes are communicated with the water collecting pipes, at least one water outlet confluence pipe is arranged at one end of each membrane assembly, and at least one water inlet confluence pipe is arranged at the other end of each membrane assembly. The water outlet collecting pipe is communicated with the water collecting pipe through a plurality of branch pipes, each branch pipe is provided with a transparent part, and when the membrane separation device is placed in water, at least one part of each transparent part protrudes out of the water surface. The membrane separation device solves the problem of low sewage treatment efficiency caused by the fact that membrane leakage cannot be found in time by a membrane separation device in the prior art.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a membrane separation device. Background technique [0002] Membrane is a material with selective separation function. According to the size of membrane filtration pore size, it can be divided into microfiltration membrane, nanofiltration membrane, ultrafiltration membrane and reverse osmosis membrane. Membrane is also widely used because of its unique function of selective separation. In the MBR sewage treatment process. Generally, the membrane separation device is made of membrane material, and the secondary sedimentation tank is replaced by the selective separation function of the membrane to realize the separation of mud and water. [0003] Usually, the membrane separation device includes a diaphragm and a water collection pipe at one end of the diaphragm, and a water pump is provided at one end of the water collection pipe. Specifically, after the treated sewage en...
