Problems solved by technology

[0002] At present, the EGSB in domestic sewage anaerobic treatment systems mostly adopts one or two sets of three-phase separators in the form of gas collecting hoods. This form of EGSB can achieve a COD removal rate of about 80% for most wastewater, but it is not suitable for high-concentration chemicals. In the case of wastewater, the reactor sludge is difficult to granulate, and the sludge loss is serious. The anaerobic sludge reactor needs to be replenished frequently to operate normally, and its COD removal rate is generally below 50%, or even less than 30%.
The cost of sewage treatment is high

Abstract

The invention discloses an EGSB solid-liquid-gas phase separation system. The system adopts a forward and reverse flow shallow layer precipitation principle for solid-liquid separation of EGSB reactormixed liquid and a baffling principle for gas-liquid separation, and comprises a solid-liquid separation device and a gas-liquid separation device that are communicated with each other. The forward and reverse flow solid-liquid separation device can effectively separate anaerobic sludge and treated sewage in the EGSB mixed liquid, prevents effluent from carrying the anaerobic sludge, and ensuresthe anaerobic sludge can stay in the reactor, so that the EGSB treatment efficiency is improved. The gas-liquid separation device adopting the baffling separation principle can mostly separate methaneentrained by the treated sewage and effectively prevents the methane from entering subsequent treatment facilities.

Description

technical field [0001] The invention belongs to the technical field of sewage treatment, and in particular relates to an EGSB solid-liquid-gas three-phase separation system. Background technique [0002] At present, the EGSB in domestic sewage anaerobic treatment systems mostly adopts one or two sets of three-phase separators in the form of gas collecting hoods. This form of EGSB can achieve a COD removal rate of about 80% for most wastewater, but it is not suitable for high-concentration chemicals. In the case of wastewater, the reactor sludge is difficult to granulate, and the sludge loss is serious. The anaerobic sludge reactor needs to be replenished frequently to operate normally, and its COD removal rate is generally below 50%, or even less than 30%. As a result, the cost of sewage treatment is high. Contents of the invention [0003] The purpose of the present invention is to overcome the defects of the prior art and provide an EGSB solid-liquid-gas three-phase sep...
