EGSB anaerobism return sludge reactor

The utility model belongs to the technical field of the return sludge reactor, a EGSB anaerobism return sludge reactor. Is related to its main technical characteristics does: be provided with the communicating pipe that has the intake pump between cell-out mouth and the EGSB anaerobic reactor's in allotment pond water inlet, said water inlet the place ahead is provided with the heating steam interface, be provided with the water distribution mechanism that is connected with the water inlet below the said EGSB anaerobic reactor, said EGSB anaerobic reactor top is provided with the marsh gas export, is being close to be provided with exteenal reflux export on the said EGSB anaerobic reactor lateral wall, this exteenal reflux export is connected with muddy water hydrocyclone separation mechanism through first pipeline, this muddy water hydrocyclone separation mechanism isolate the mud mouth and said allotment pond intercommunication, be provided with internal reflux export on the said EGSB anaerobic reactor lateral wall, the internal reflux pipe of this internal reflux export through having the internal reflux pump with communicating pipe intercommunication. Improved the sludge concentration in the anaerobic reactor, the poisonous difficult degradation material of intaking is diluted in can be better mix to improved EGSB anaerobic reactor's the ascending velocity of flow, the improvement waste water that can be better and the contact reaction of mud
