Description

technical field

[0001] The invention belongs to the technical field of environmental protection equipment, and in particular relates to an improved filter device. Background technique

[0002] Membrane filtration technology has become a marginal science integrating polymer, chemical engineering, biology, physics and mathematics, which will have an immeasurable impact on changing the energy structure of the industry, environmental protection and the development of new technologies.

[0003] At present, membrane filtration technology has been widely used in sewage treatment. However, the existing membrane filtration devices generally adopt a static filtration method, which has the following disadvantages: after a period of filtration, colloidal particles and solute macromolecules are adsorbed on the membrane surface or in the membrane pores, and concentration differences on the membrane surface are prone to occur. Polarization and membrane fouling phenomena reduce the membran...
