Abstract

The invention provides an oxidation ditch membrane bioreactor, a wastewater treatment process and an application thereof. An oxidation ditch is arranged in the oxidation ditch membrane bioreactor; the oxidation ditch membrane bioreactor comprises an anoxic zone and an aerobic zone which are continuously arranged or an anaerobic zone, the anoxic zone and the aerobic zone which are continuously arranged; one or more membrane bio-reaction zones are arranged in the aerobic zone; a sewage inlet is arranged in the anoxic zone or the anaerobic zone; the membrane bioreactor is organically combined with the oxidation ditch; the advantages of S-MBR and R-MBR are fully utilized; sludge backflow is reduced or cancelled; the technical process and the power equipment are simplified; as S-MBR running, the oxidation ditch membrane bioreactor can realize in-situ online cleaning and soaking cleaning; as R-MBR running, the oxidation ditch membrane bioreactor can increase the land use rate and simplify operation and maintenance; an aerating system is optimized; the pulse aeration is combined for guaranteeing the valid oxygen demand in each zone, so that energy consumption waste is avoided. According to the invention, through the optimal combination of the reactor, the processing effect of nitrogen and phosphorus removal can be enhanced, the energy consumption can be saved and the land occupation can be saved.

Description

technical field [0001] The invention relates to the technical field of biological treatment and reuse of biodegradable sewage, in particular to an oxidation ditch membrane bioreactor and its sewage treatment process and application. Background technique [0002] Membrane biological reactor is suitable for urban sewage and biodegradable industrial wastewater treatment and reuse projects. It is a new type of efficient sewage treatment process that combines membrane separation technology with traditional sewage biological treatment processes. Membrane is a sewage treatment process that replaces conventional gravity precipitation solid-liquid separation to obtain effluent, and can change the reaction process and improve reaction efficiency as the separation medium, referred to as MBR. [0003] In the MBR process, the concentration of microorganisms is high, the volume load of the device is large, the land occupation is small, the effluent water quality is good, and can be reused...
