Abstract

The invention provides an upflow anaerobic sludge blanket (UASB) reactor adopting a guide impeller, relating to ASB reactors. The UASB reactor adopting the guide impeller comprises a tank, an upper cover, a scum separator, a three-phase hydrocyclone and inflow water distribution parts, wherein each inflow water distribution part comprises an inflow water distribution pipe and an impeller guide plate. The UASB reactor adopting the guide impeller adopts the guide impeller to guide wastewater to form sludge reaction cycle, takes full advantage of the wastewater impact to stir a sludge blanket, guides the sludge and wastewater mixed liquor to carry out interference-free zoned flow and sludge and water separation in the three-phase hydrocyclone and has the effect of overcoming the defect of existing three-phase separators that upward wastewater upflow and downward sludge return interfere with each other and the defect that existing UASB reactors have poor impact resistance.

Description

technical field [0001] The present invention is an upflow anaerobic sludge bed reactor with a guide wave wheel, which relates to an anaerobic sludge bed reactor, in particular to a process that adopts a guide wave wheel to guide the circulation of waste water and to guide the waste water in the swirl An upflow anaerobic sludge bed reactor for mud-water separation in a liquid three-phase separator. Background technique [0002] The upflow anaerobic sludge bed reactor (UASB reactor for short) consists of three functional areas: the water distribution area at the bottom, the sludge reaction area in the middle, and the gas-liquid-solid three-phase separation area (including the sedimentation area) at the top. The working process of the UASB reactor is: wastewater flows in from the bottom of the anaerobic sludge bed, the wastewater and the sludge in the sludge layer are mixed and contacted, and the microorganisms in the sludge decompose the organic matter in the wastewater and co...
