The invention discloses a membrane component of a membrane bioreactor, wherein the membrane component comprises a support membrane box, microporous membranes and edge sealing frames; two opposite side walls of the support membrane box are respectively provided with a plurality of through water inlet holes, one end of the support membrane box is provided with a drain hole, and the drain hole is connected with an output water pipe; the outer sides of the two side walls are respectively laid with the microporous membranes, the microporous membranes are polyester membrane nets, non-woven fabric membrane nets, nylon nets or stainless steel wire nets, and the pore diameters of the microporous membranes are 10-200 microns; and the edge sealing frames are used for sealing the outer edges and the two side walls of the microporous membranes and are mounted on the two side walls. According to the invention, the problem that an existing MBR process cannot be widely applied due to high price of a membrane component is solved.
Description
technical field [0001] The invention relates to the technical field of water treatment equipment, in particular to a membrane module of a membrane bioreactor. Background technique [0002] At present, most sewage treatment plants mainly adopt traditional activated sludge process and biofilm process, but these two types of processes have obvious shortcomings: such as large footprint, poor effluent quality, large amount of excess sludge and high energy consumption. [0003] The increasingly serious water pollution situation also requires further improvement of effluent water quality. In recent years, various new and improved high-efficiency sewage treatment technologies have emerged as the times require. Among them, the membrane bioreactor combined process has the advantages of good effluent quality, small equipment footprint, high sludge concentration, and low residual sludge output, and has been widely used in various types of wastewater. [0004] However, membrane fouling ...
