Abstract
The invention relates to a modularized flat-plate type filter membrane element used for a membrane bioreactor, and belongs to the field of sewage treatment. The modularized flat-plate type filter membrane element comprises a plurality of stacked rectangular inner membrane sheets. Each of the rectangular inner membrane sheets comprises a guiding sheet in the middle and straight frames at the two sides. Each of the straight frames at the two sides of each of the inner membrane sheets is provided with a concave-convex plug-in structure. The inner membrane sheets are assembled into one part by the concave-convex plug-in structures. The two side surfaces of each of the inner membrane sheets are respectively covered with a filtering membrane. One of the straight frames of each of the inner membrane sheets is provided with square filtrate guiding outlets fixed to suction pipes. The suction pipes are connected to connecting pipes. The modularized element is utilized to replace a single-sheet flat-plate type filter membrane element, and is light in weight, convenient to transport and install, and easy to maintain and change. The total membrane area volume of a single filter membrane module assembled by the modularized element is larger. The modularized flat-plate type filter membrane element can be widely used in designing and manufacturing field of the membrane bioreactor in a sewage treatment technology.
Description
technical field [0001] The invention belongs to the field of sewage treatment, in particular to a membrane bioreactor for sewage biological treatment. Background technique [0002] Membrane Bio-Reactor (MBR) is a new and efficient sewage treatment process that combines high-efficiency membrane separation technology with traditional biological methods. It is the latest technology for environmental engineering sewage treatment and the realization of sewage resources. Now It has become one of the most active projects in the research and development of membrane separation technology. [0003] This technology combines sewage biological treatment technology with membrane separation technology. First, it uses biochemical technology to degrade organic matter in water, domesticates dominant fungi, and blocks bacteria. The secondary settling tank at the end of traditional biological treatment technology maintains a high concentration of activated sludge in the bioreactor and increase...
