a sewage treatment system

Abstract

The invention discloses a high-efficiency sewage treatment system, which can simultaneously solve the problems of easy hardening and passivation of micro-electrolysis fillers and reduction of membrane flux caused by pollutants intercepted by MBR membrane components through the coupling of micro-electrolysis treatment devices and MBR membrane bioreactors. , give full play to the synergistic effect of the two. The advantage of the present invention is that: the present invention places the iron-carbon filler in the rotor core divided into a plurality of compartments by the separator, and the rotor core rotates when the sewage is treated. The rotation of the core rolls in the chamber, which can effectively avoid the hardening and passivation of the filler. On the other hand, the rotation of the rotor core can stir the sewage water flow in the coupling reactor, and the disturbed water flow forms a scour on the surface of the membrane, which can effectively avoid pollution. The membrane flux is reduced due to the stagnation of substances on the membrane surface, which greatly reduces the frequency of membrane cleaning and replacement, and reduces the production cost while giving full play to the role of micro-electrolysis and membrane biological reaction in sewage treatment.

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...
