Abstract

The invention discloses a co-flocculation air-floating anaerobic bioreactor and a method thereof. The co-flocculation air-floating anaerobic bioreactor mainly comprises a biological reaction area, a dosing Mixed Zone and a flocculation air flotation area, wherein the biological reaction area is provided with a sludge discharge pipe, a three-phase separator and a lifting pipe; the dosing Mixed Zoneis provided with a dissolving tank, a flow control valve and a jet device; the flocculation air-floating zone is provided with a direct-current type vortex reaction tank, a flow-reducing chamber, a slag-scraping machine, a slag-collecting tank, a drop-down pipe and a current-collecting chamber. The co-flocculation air-floating anaerobic bioreactor combines the anaerobic biological reaction and the co-flocculation air flotation process, and uses the biogas generated by the anaerobic biological reaction for air-floating removal of the particulate matter, and meanwhile, generates the copolymerization adhesion effect. The method has the advantages of good water quality, high medicament saving, high efficiency and low energy consumption.

Description

technical field [0001] The invention belongs to the field of environmental protection equipment, and in particular relates to a co-flocculation air flotation anaerobic bioreactor and a method thereof. Background technique [0002] Anaerobic bioreactor is a device that uses anaerobic microorganisms to convert organic matter in wastewater into biogas, thereby achieving water purification. The main advantages of anaerobic bioreactors are: no need for oxygen supply, generation of biogas energy, less residual sludge, and low nutritional requirements. Therefore, anaerobic bioreactors are widely used in the field of treating high-concentration organic wastewater. After years of development, anaerobic bioreactors have various configurations and have experienced three stages of development. The first generation anaerobic bioreactors are mainly represented by traditional anaerobic digesters; the second generation anaerobic bioreactors are mainly The above flow sludge bed reactor (UAS...
