Abstract

The invention discloses a filter device comprising transmission cross-flow flat sheet membrane members and a method, and belongs to the technical field of environmental engineering. The filter devicemainly comprises the transmission cross-flow flat sheet membrane members, a water inlet tank, a collection tank, a pressure pump, a pressure gauge, an electronic flowmeter and a water quality detector, wherein the three cross-flow flat sheet membrane members operate in a parallel manner in the filter device, each cross-flow flat sheet membrane member comprises a casing, a movable door, a driving shaft, a driven shaft, a roller I, a roller II, a transmission membrane assembly and a driving motor, the transmission membrane assembly is stretched and arranged on the roller I and the roller II in asleeving manner, and the ring-shaped transmission membrane assembly can rotate at a uniform speed under drive of the driving shaft. By means of moving permeable membranes, transverse shear force between wastewater and the permeable membranes can be increased, so that the permeable membranes are prevented from being blocked, bacteria breeding can be prevented to a certain extent by the increased transverse shear force, and permeability is improved.

Description

Technical field [0001] The invention belongs to the technical field of environmental engineering, and specifically relates to a filter device and a method composed of a transmission cross-flow flat membrane member. Background technique [0002] Vitamin C is currently the world's largest production and sales volume and the widest application range of vitamins. my country's vitamin C production ranks first in the world, and its production process consumes huge amounts of water and waste water. Therefore, the advanced treatment of vitamin C wastewater and the realization of regeneration and reuse are of great significance. Vitamin C wastewater, as a typical fermentation and pharmaceutical wastewater, has the characteristics of high color, high salinity and high concentration of organic matter. The water quality is complex. Its biochemical tail water contains organic matter, inorganic salts and microorganisms. Among them, dissolved organic matter such as polysaccharides, proteins, h...
