Problems solved by technology

Although the MBR flat separation membrane provided by this patent solves the problems of heavy weight and difficult free flow of water in the traditional MBR flat membrane, the honeycomb flexible support three-dimensional grid is fixed on the inner surface of the flow guide cloth, and its mechanical stability is poor. Easily damaged during use

Abstract

The invention belongs to the field of water processing equipment, and discloses an MBR flat membrane element, which comprises a support plate, guide cloth, and filter membranes. The guide cloth is welded on two lateral surfaces of the support plate. The filter membranes are arranged on the external surfaces of the guide cloth and welded on the external frame of the support plate. Two lateral surfaces of the support plate are provided with guide grooves. The guide grooves are vertically arranged in the inner surfaces of the guide cloth; the direction of the guide grooves is the same as the flowing direction of fluids; and the guide grooves are staggered from each other. By arranging guide grooves in the support plates, the resistance during the filtering process is reduced, the water flux is increased, and the operation cost is reduced.

Description

technical field [0001] The invention belongs to the field of water treatment equipment, in particular to an MBR flat membrane element. Background technique [0002] The submerged membrane bioreactor (MBR) is an organic combination of membrane separation technology and biotechnology. It replaces the secondary settling tank and conventional filtration unit of the traditional activated sludge method with ultrafiltration or microfiltration membrane separation technology, so that the hydraulic retention time ( HRT) and mud age (STR) are completely separated. The submerged membrane bioreactor (MBR) has high-efficiency solid-liquid separation capability, the effluent water quality is good, the suspended solids and turbidity are close to zero, and it can intercept biological pollutants such as Escherichia coli. The water quality is obviously better than the traditional sewage treatment process. It is an efficient and economical sewage resource technology; and the submerged membrane...
