Description

technical field

[0001] The invention relates to a vibrating device with an Oldham coupling, which is used to solve the problem of membrane pollution, and a membrane treatment system using the vibrating device, belonging to the technical field of membrane separation. Background technique

[0002] Membrane separation is a unit operation technology that separates components of different sizes in the feed liquid, and is widely used in sewage treatment, water supply and drainage, beverage production, pharmaceutical production and oil treatment and other fields. In the application of membrane separation technology, the problem of membrane fouling has a greater impact, which means that with the prolongation of use time, impurities in the high-pressure side feed liquid will gradually accumulate on the surface of the membrane or enter the pores of the membrane, resulting in a decrease in membrane flux and a decrease in treatment efficiency. Reduced, seriously affecting the service li...
