Abstract

The invention discloses an efficient sewage treatment system, which can simultaneously solve the problems of easy hardening and passivation of a micro-electrolysis filler and membrane flux reducing caused by interception of pollutants by an MBR membrane assembly by coupling a micro-electrolysis treatment device and an MBR membrane bioreactor so as to completely achieve the synergistic effect of the micro-electrolysis treatment device and the MBR membrane bioreactor. According to the invention, an iron-carbon filler is placed in a rotor core divided into a plurality of chambers by partition plates, the rotor core rotates during sewage treatment, the iron-carbon filler rolls in the chamber along with the rotation of the rotor core while the iron-carbon filler is subjected to a micro-electrolysis reaction so as to effectively avoid the hardening and passivation of the filler, the rotation of the rotor core can stir the sewage flow in the coupling reactor, and the disturbed water flow forms scouring on the surface of the membrane, so that the membrane flux reducing caused by retention of pollutants on the surface of the membrane can be effectively avoided, the cleaning and replacing frequency of the membrane is greatly reduced, and the production cost is reduced while the sewage treatment effects of micro-electrolysis and membrane biological reaction are fully exerted.

Description

technical field [0001] The invention relates to the field of water treatment, in particular to a sewage treatment system. Background technique [0002] Non-heavy-related wastewater includes waste water after pretreatment of waste emulsion, waste mineral oil regeneration system drainage, circulating cooling water system drainage, physical and chemical workshop scrubber wastewater, boiler regular drainage and waste gas treatment system drainage, non-heavy wastewater due to the high concentration of organic matter , Poor biodegradability leads to poor final effect of sewage treatment. Membrane Bio-Reactor (MBR) is a new type of water treatment technology that combines a membrane separation unit with a biological treatment unit. It uses biological reactions to biodegrade organic matter in sewage, and uses membranes as separation media to replace conventional Gravity sedimentation is a sewage treatment method for solid-liquid separation to obtain high-quality and stable effluent...
