Abstract

The invention discloses a temperature-control UASB anaerobic ammoxygen denitrifying method and equipment, which comprises the following parts: cylinder (1) of UASB biological reactor, anaerobic sludge bed (2) on the lower part of cylinder (1), three-phased separator (3) on the top, temperature-control system (4) on the exterior of anaerobic sludge bed (2), wherein the anaerobic sludge bed (2) is active sludge after aerobic and anaerobic disposal in the SBR reactor, which cultures anaerobic ammoxygen strain tamed by microbe rapidly.

Description

technical field [0001] The invention relates to a temperature-controlled UASB anaerobic ammonium oxidation denitrification method and its equipment, specifically a method for removing the three-phase separator in the original UASB reactor, constructing a temperature control system outside the anaerobic reaction bed, and simultaneously passing the landfill leachate The role of anaerobic sludge bed after aerobic anaerobic activated sludge domestication to promote a new type of bioreactor equipment for anaerobic ammonia oxidation in a temperature-controlled UASB bioreactor. Background technique [0002] UASB is the abbreviation of Up-flow Anaerobic Sludge Blanket. In 1982, Lettinga first used this reactor for anaerobic treatment of organic wastewater. The UASB process is an anaerobic treatment technology for treating high-concentration organic wastewater (especially wastewater containing carbohydrates). The UASB reactor consists of two parts: a reaction zone and a settling zon...
