Comb-like membrane-bioreactor having free end

Abstract

The invention discloses a comb shaped film-bioreactor with free end, which is characterized by the following: possessing film-biological reaction tank; equipping a baffle in the reaction tank; dividing the reaction tank into a sludge mixing oxidation area and a film component part water outlet area with the baffle; communicating the bottom of the sludge mixing oxidation area and the bottom of the film component part water outlet area; arranging a liquid level controller at the upper of the sludge mixing oxidation area; equipping an aeration head at the bottom of the film-biological reaction tank; assembling a comb shaped film-component part with a free end in the film component part water outlet area; connecting to third valve, outflow tube, subatmospheric pressure gage, water outlet sorption pump and pure water tank; connecting the water outlet sorption pump with a time delay relay; connecting the siphon tube road to the subatmospheric pressure gage and the pure water tank; connecting the aeration head to gas flow counter, second valve and aeration pump; connecting the liquid level controller to the first valve and raw water tank. This invention possesses the advantages of simple structure, convenient production and low energy consumption.

Description

technical field [0001] The invention belongs to the field of sewage treatment, in particular to a comb-shaped membrane-bioreactor with free ends. Background technique [0002] Membrane Bioreactor (MBR) is a new and efficient process for wastewater treatment that combines membrane separation technology with microbiology and biochemistry. Compared with traditional biochemical wastewater treatment technologies, it has solid-liquid It has the advantages of good separation effect, high biochemical efficiency, excellent effluent quality, centralized equipment, small footprint, high sludge concentration, low sludge load, easy management and automatic control. Membrane-bioreactor is mainly composed of two parts: bioreactor and membrane separator (membrane module). The bioreactor is mainly the main place for the degradation of pollutants in wastewater; the membrane separator (membrane module) is mainly for solid-liquid separation and interception of some macromolecular compounds.
