Abstract

The invention discloses a pulse turbulence membrane bioreactor. The pulse turbulence membrane bioreactor comprises a hollow fibrous membrane bioreactor, an air blower, a suction pump, a sludge pump and a pulse generator, wherein the air blower is communicated with an aerator pipe at the bottom of the hollow fibrous membrane bioreactor through an electromagnetic valve and a pipeline; one end of the suction pump is communicated with the water outlet of the hollow fibrous membrane bioreactor; the suction pump is connected to a sludge outlet formed in the bottom of the hollow fibrous membrane bioreactor; the pulse generator comprises a water storage tank, a bell jar, an exhaust pipe, a siphon breaking pipe, a siphon manufacturing exhaust pipe and a pulse drain pipe. The pulse turbulence membrane bioreactor disclosed by the invention has the advantages that the purpose of washing a membrane is achieved in the water filtration process of the hollow fibrous membrane, sludge or particles are unlikely to be adsorbed on membrane fibers to cause blockage, the service life of the membrane fibers is prolonged, and the water filtration efficiency of the membrane bioreactor is improved.

Description

technical field [0001] The invention relates to a membrane bioreactor, in particular to a hollow fiber membrane bioreactor with pulse and turbulence functions. Background technique [0002] Membrane Bio-Reactor (MBR) is a new type of water treatment technology that combines membrane separation unit and biological treatment unit. Retention, saving the secondary settling tank, thereby reducing the footprint of the sewage treatment facility, and reducing the amount of residual sludge by keeping the sludge load low. However, membrane bioreactors are susceptible to clogging caused by sludge or particles adsorbed on the membrane filaments, resulting in discontinuous water discharge, low water filtration efficiency, and short service life of the membrane. This situation is very serious during shutdown. Contents of the invention [0003] The purpose of the invention is to disclose a membrane bioreactor which is difficult for sludge or microparticles to be adsorbed on the membran...
