The invention provides an off-line regeneration device for a ceramic membrane. The off-line regeneration device comprises a device body, a hot air heating furnace, a fan and a ceramic diaphragm bearing platform, wherein an air outlet of the hot air heating furnace is connected with an air inlet of the fan; an air outlet of the fan is communicated with the device body, and feeds air into the device body; a cavity is formed in the device body which is provided with an opening and closing door; the ceramic diaphragm bearing platform enters and leaves the device body through the opening and closing door and is located at an upper part of the air outlet. The off-line regeneration device has the advantages that the ceramic membrane regeneration device has characteristics of simple structure, high safety and reliability, high operating efficiency and low loss; the device can effectively remove pollutants attached to a membrane surface by drying and dewatering a ceramic diaphragm and baking the diaphragm when the membrane flux is attenuated during online operation or still cannot be recovered after online cleaning, realize complete regeneration of a ceramic membrane module in an offline manner, improve the anti-pollution ability of a flat membrane bioreactor, avoid structural injury and damage easy to occur in a general acid-base cleaning method, and solve a problem that the ceramic membrane cannot be cleaned thoroughly by a chemical method after long-term pollution and blockage.
Description
technical field [0001] The invention relates to an off-line regeneration device for ceramic membranes. Background technique [0002] The ceramic membrane bioreactor is a flat membrane placed in the reactor, which meets the needs of microbial growth through aeration and support, and then removes pollutants. This treatment technology can meet a variety of sewage treatment processes. The subsequent membrane fouling will cause the membrane flux to decrease and the water production rate to decrease. In order to reduce the degree of membrane fouling, off-line or on-line chemical cleaning is usually used, but after long-term use, even long-term cleaning will still cause the attenuation of membrane energy, making the system unable to meet the treatment requirements. At this time, the recovery of membrane flux can only be achieved by off-line means, mainly by chemical cleaning method soaked in chemical solution, but this cleaning method may damage the structure of the diaphragm, ca...
