Description

technical field [0001] The invention relates to an integrated membrane biological reaction water treatment equipment which combines a circulating activated sludge system process and a membrane filtration technology, and belongs to the technical field of environmental engineering. Background technique [0002] Membrane separation technology is considered to be one of the most promising high-tech technologies from the end of the 20th century to the middle of the 21st century. Combining membrane separation technology with traditional biological treatment in sewage treatment constitutes a Membrane Bioreactor (MBR for short). . Membrane bioreactor has been widely used due to its simple operation, low sludge yield, small footprint, effective removal of ammonia nitrogen, very effective treatment of refractory industrial wastewater, and reuse water treatment. In various fields, from water supply treatment to domestic sewage and many industrial wastewater treatment. [0003] In the...
