Abstract

The invention discloses a novel efficient low-consumption UASB (upflow anaerobic sludge blanket) +ABR (anaerobic baffled reactor) granular sludge process based brewing industrial wastewater treatmentmethod. A UASB+ABR reactor is adopted, a sewage speed-regulation constant-flow pump is mounted on the lower portion of the lateral side of the UASB+ABR reactor, a first liquid flow meter is arranged on the lateral side of the sewage speed-regulation constant-flow pump, and a backflow speed-regulation constant-flow pump, a second liquid flow meter and a sludge discharging pipeline are mounted on the lateral side of the UASB+ABR reactor. The inner bottom of the UASB+ABR reactor is provided with a first reaction chamber, and a three-phase separator is arranged above a second reaction chamber which is arranged above the first reaction chamber. The novel efficient low-consumption UASB+ABR granular sludge process based brewing industrial wastewater treatment method has advantages that by internal modification of the UASB+ABR reactor, a flow guide is additionally arranged below the three-phase separator, three reaction chambers are formed in the whole reactor, and accordingly an anaerobic sludge granulation process is quickly promoted by sludge floc to quickly degrade organics.

Description

technical field [0001] The invention relates to the technical field of environmental protection equipment, in particular to a novel high-efficiency and low-consumption UASB+ABR granular sludge method for treating brewing industrial wastewater. Background technique [0002] Alcohol lees and koji wine brewing wastewater are waste liquids discharged from the production of alcohol and koji wine, which contain a large amount of organic matter. The solid content is 5-6%, PH3.5-4.5, CODcr5-60,000 mg / L, BOD53-40,000 mg / L, and the main pollutants include starch, sugar, alcohol, aldehyde, ester, fiber Su and so on. The research and development of the effective utilization of these components is mainly the UASB+ABR granular sludge method, but the process of brewing wastewater entering the UASB+ABR reactor from flocculent to granular sludge after pretreatment is an extremely complicated microbial and biochemical process. A process that is jointly restricted by many factors. The main ...
