Description
technical field [0001] The invention belongs to the field of membrane separation devices, in particular to a rotary cross-flow flat ceramic membrane separation turntable. Background technique [0002] In recent years, with the rapid development of membrane separation technology, from microfiltration, ultrafiltration, nanofiltration to reverse osmosis, it has been widely used in sewage treatment, drinking water purification, seawater desalination, industrial separation and other fields. At present, the preparation technology of membrane materials (including polymer organic membranes and inorganic membranes) is quite mature, but the industrial application of membranes is relatively backward. For example, the membrane components of flat membranes and hollow fiber membranes of polymer materials are static. Cross-flow filtration is formed by aeration; inorganic tubular membranes mainly rely on pumps to increase the flow rate of the liquid to be treated to form cross-flow filtrati...
