Separated anaerobic baffled reactor and work method of separated anaerobic baffled reactor

Abstract

The invention discloses a separated anaerobic baffled reactor (an ABR (anaerobic baffled reactor) for short), which comprises a reactor body, a plurality of upper baffle plates and a plurality of lower baffle plates, wherein the upper baffle plates are arranged at the top of the reactor body, the lower baffle plates are arranged at the bottom of the reactor body, the upper baffle plates and the lower baffle plates respectively adopt the vertical installation, two ends of the reactor body are respectively provided with a water inlet pipe and a water outlet pipe, the reactor body are sequentially divided into six separation chambers in the water flow direction by the upper baffle plates and the lower baffle plates, and acid production and methane production are respectively carried out in different separation chambers so that the acid production and the methane production are physically separated. The separated anaerobic baffled reactor has the advantages that the structure is simple, the manufacture cost is low, the volume utilization rate is high, the blockage is avoided, no special requirements on the settling property of organisms exist, the sludge yield is low, the rest sludge quantity is small, the sludge age is high, the sludge growth on the carrier body is not needed, the operation of the mud and water separation process by a subsequent settling pool is not needed, the hydraulic detention time is short, the operation in the intermittent mode can be realized, the hydraulic resistance is realized, the organic impact load capability is high, and the reactor can be operated for a long time without sludge discharging. The invention also discloses a work method of the reactor.

Description

technical field [0001] The invention relates to the field of wastewater treatment, in particular to a separate anaerobic baffle reactor and a working method thereof. Background technique [0002] Anaerobic digestion is a complex biological process, and anaerobic fermentation also exists widely in nature. Under anaerobic conditions, where there is water, organic matter is easily digested anaerobically, and the representative products of anaerobic digestion are methane and hydrogen sulfide. Anaerobic microorganisms are microorganisms that can decompose organic matter in the absence of oxygen. Their distribution on the earth is very wide. These include the intestines and stomachs of humans and animals, the woody tissues of plants, the sediments of the seabed, lake bottom, pond bottom, and river bays, as well as various sludges, swamps, cesspit, and rice field soils. There are different numbers of anaerobic microorganisms. [0003] The anaerobic digestion treatment process de...

Problems solved by technology

Traditionally, the acidogenic phase and the methanogenic phase are combined in one reactor, but the acidogenic phase and the methanogenic phase require different dominant strains for different reaction requirements, so it is difficult to control the dominant strains
