Hollow plate type ceramic membrane bioreactor and wastewater treatment method

Abstract

The invention discloses a hollow plate type ceramic membrane bioreactor and a wastewater treatment method, relates to the technical field of sewage treatment devices, and aims to solve the problem ofhigh use cost due to the fact that a membrane assembly generally has the service life of about 5 years and needs to be replaced after expiration. A biochemical tank is arranged on one side of a ceramic membrane tank, a control chamber is arranged on the other side of the ceramic membrane tank, five ceramic membrane mechanisms are arranged in the ceramic membrane tank at equal intervals, hollow plate type ceramic membranes are arranged in the ceramic membrane mechanisms, and cleaning brush frames are arranged outside the ceramic membrane mechanisms. Cleaning brushes are arranged on the two sides of the hollow plate type ceramic membrane and fixedly connected with the cleaning brush frames, a mud scraping motor fixing base is fixedly installed at the lower end of the interior of the ceramicmembrane tank, a mud scraping motor is fixedly arranged above the mud scraping motor fixing base, and a mud scraping mechanism is arranged at the output end of the mud scraping motor.

Description

technical field [0001] The invention relates to the technical field of sewage treatment devices, in particular to a hollow plate ceramic membrane bioreactor and a wastewater treatment method. Background technique [0002] Membrane bioreactor is a new type of wastewater treatment system that organically combines membrane separation technology and biological treatment technology. Replace the terminal secondary sedimentation tank of traditional biological treatment technology with membrane modules, maintain a high concentration of activated sludge in the bioreactor, increase the organic load of biological treatment, thereby reducing the footprint of sewage treatment facilities, and reduce the remaining sewage by maintaining low sludge load amount of mud. Mainly use membrane separation equipment to intercept activated sludge and macromolecular organic matter in water. [0003] The high cost of membrane modules in membrane bioreactors leads to an increase of project investment ...
