Abstract

The invention provides an alternate two-stage aerobic membrane bioreactor. The alternate two-stage aerobic membrane bioreactor comprises a first reactor MRR1, a second reactor MBR2, a regulating tank I, a flow meter, a valve, a centrifugal pump, an automatic-control motor case II, a water storage tank IV, an alkali liquor box III, an acid liquor box V, a first air blower GFJ1, a second air blower GFJ2, a perforated pipe aerating apparatus and an inka aeration apparatus. The invention can realize that after high concentrated organic waste water is hydrolyzed and acidized, the effluent is not subjected to methanogenic-phase reaction but directly enters into the aerobic membrane bioreactor for treatment, so that the effluent has qualified quality; and in the process, the effluent is ensured to be continuous, membrane fouling is retarded, membrane flux is recovered to the maximum limit, and full-automatic control, safety, stability and high efficiency are achieved.

Description

technical field [0001] The invention relates to a sewage treatment device. Background technique [0002] Membrane bioreactors have only been developed for decades, but they are developing rapidly, mainly because membrane bioreactors (MBR) combine biological treatment units and membrane treatment technologies, and the quality of effluent water even reaches the standard for reclaimed water reuse. However, due to serious membrane fouling, limited organic load rate, low level of self-control, and discontinuous effluent, its further popularization and application are affected. The membrane bioreactor disclosed in the Chinese patent application number 02104266.7 is composed of a membrane module, a clean water tank, a water pipeline, a gas pipeline and a water pump. The membrane module is composed of a hollow fiber bundle, an aeration tube, an aeration nozzle, a collection Composed of water pipes, its characteristics are: online monitoring measures are used to effectively detect m...
