Abstract

The invention relates to an ultrasound vibration type rolling type ultrafiltration membrane group device and an ultrafiltration device thereof. The ultrasound vibration type rolling type ultrafiltration membrane group device comprises a rolling type ultrafiltration membrane, a membrane shell and ultrasonic wave oscillators, wherein the rolling type ultrafiltration membrane is arranged in the membrane shell, the ultrasonic wave oscillators are arranged on an end socket and are arranged outside the membrane shell in horizontal and vertical directions, and the improvement of a membrane flux and deceleration of membrane pollution by the ultrasound vibration can be enhanced; and the rolling type ultrafiltration membrane comprises a ultrafiltration membrane group, a water collecting pipe, the end socket and a flow channel, and at least one ultrafiltration membrane group and the flow channel are successively overlaid so as to be rolled on the water collecting pipe and arranged in the membrane shell after being sleeved with the end socket. According to the ultrasound vibration type rolling type ultrafiltration membrane group device provided by the invention, the flux is large, the antifouling property is good, the service life is long, and the cost is low.

Description

technical field [0001] The invention belongs to the technical field of environmental protection, and in particular relates to an ultrasonic vibration roll-type ultrafiltration membrane assembly and an ultrafiltration device thereof. Background technique [0002] As a new type of fluid separation technology, ultrafiltration has become a very competitive fluid in the fields of biochemistry, food, and environmental protection due to its remarkable advantages such as normal temperature operation, no phase change, high separation efficiency, and stable permeate quality. Separation technology and is highly valued worldwide. Although ultrafiltration membrane technology has achieved industrial application, it is still in the stage of development and perfection, and there are still some defects that need to be further solved. For ultrafiltration membranes, concentration polarization and membrane fouling are the main bottlenecks restricting its development. Concentration polarization...

Problems solved by technology

However, the roll-type membrane also has the disadvantages of strict water pretreatment requirements, high membrane strength requirements, and flow channels are easily blocked by fouling. It is necessary to reduce concentration polarization and reduce membrane fouling through the structural design of the membrane stack.
