Problems solved by technology

However, the UASB process also has the following disadvantages: First, although it can treat high-concentration organic wastewater, it is generally difficult to discharge it up to the standard; second, it takes a long time to start up, and sludge granulation has an important impact on the wastewater treatment effect; For wastewater, the treatment effect of ammonia nitrogen is poor. If denitrification and denitrification are not considered, it is mainly used to remove organic pollutants

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, sludge bed (2) on the lower part of cylinder (1), three-phased separator (4) on the top, biomembrane of flexible fill between sludge bed (2) and three-phased separator (4), wherein multiple microbe is set on the bottom of sludge bed (2), which contains anaerobic ammoxygen bacteria on the microbe layer to denitrify partial wastewater.

Description

technical field [0001] The invention relates to a UASB-biofilm anaerobic ammonium oxidation equipment, specifically a kind of UASB by adding soft fillers in the UASB reactor and using the combined action of the anaerobic sludge bed and the biofilm after the activated sludge is domesticated to promote UASB - A new type of bioreactor equipment for anaerobic ammonium oxidation by biofilm composite 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. UASBT technology 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 zone. The reaction zone is composed of the sludge bed and the sludge blanket, and the settling zone is composed of the settling compartment and the gas-liquid-solid separ...
