Abstract

The invention discloses a membrane unit provided with a scrubbing mechanism and a water purifier using the membrane unit, and belongs to the technical field of drinking water purification equipment. The membrane unit is provided with a scrubbing part; the scrubbing part is driven by a water solution or external power to do a reciprocating motion for performing frictional cleaning on the surface of a separation layer of a membrane element; the flowing water solution is used for performing hydraulic cleaning on the scrubbing part and the membrane element; the water purifier using the membrane unit is short in water treatment process; a system is simple; the service life of the membrane element is long; the concentrated water solution in a preparation process of purified water does not serve as wastewater to be discharged.

Description

technical field [0001] The invention relates to a membrane unit with a scrubbing mechanism and a water purifier using the membrane unit, in particular to domestic drinking water treatment, and belongs to the technical field of membrane water treatment equipment. Background technique [0002] Membrane water treatment has been widely used in the fields of deep purification of tap water, seawater desalination, industrial pure water preparation, sewage treatment and reuse, and industrial concentration. [0003] In the field of membrane water treatment, membrane fouling and membrane cleaning industry common key technical issues, high water recovery rate and long service life of membrane elements are the most common goals of the industry. [0004] At present, household reverse osmosis water purifiers continue to use industrial reverse osmosis water treatment technology, mainly using roll-type reverse osmosis membrane elements, 5-stage purification process, and cross-flow filtratio...
