Problems solved by technology

[0007] In order to solve the problem that the biogas generated in the related technology is easily affected when the bottom sludge is stirred, when the reactor operation effect is not good and the water inflow is small, it is easy to make the effect of the biogas stirring the bottom sludge not good, and the waste water and sludge have to be separated. To fully contact and react, resulting in serious sludge deposition at the bottom and poor sludge removal technical problems, the application provides an internal circulation anaerobic reaction system

Abstract

The invention relates to the technical field of industrial wastewater, and discloses an internal circulation anaerobic reaction system, which comprises an anaerobic tank body, and is characterized inthat a reaction region is arranged in the anaerobic tank body; A biogas collection chamber is arranged at the top of the anaerobic tank body and connected with the water seal tank through a biogas collection pipe and a biogas main pipe, the water seal tank is connected with a biogas outlet pipe, and biogas is discharged through the biogas outlet pipe; An effluent weir is arranged at the inner topof the anaerobic tank body and is provided with a water outlet pipe; A three-phase separator is arranged at the inner top of the anaerobic tank body; A water distribution device is arranged at the bottom of the anaerobic tank body; A jet device is arranged at the outer bottom of the anaerobic tank body, a water outlet of the jet device is connected with the part, located outside the anaerobic tankbody, of the water distribution device, a gas guide port of the jet device is connected with a biogas main pipe through a biogas guide pipe, and a water inlet of the jet device is connected with a circulating water pipe arranged between the three-phase separator and the effluent weir. The reaction speed of wastewater and sludge can be increased, the sludge removal effect is improved, and sludge deposition is avoided.

Description

technical field [0001] The present application relates to the technical field of anaerobic treatment of industrial wastewater, in particular to an internal circulation anaerobic reaction system with denitrification function. Background technique [0002] With the development of industrialization, the pollution of the water environment is becoming more and more serious. Anaerobic technology is usually used for the treatment of high-concentration sewage and wastewater. The mud can be in a mixed state as much as possible. [0003] In the process of implementing the embodiments of the present disclosure, it is found that there are at least the following problems in the related art: the generated biogas is easily affected by the quality of the influent water when the sludge at the bottom is stirred, and when the reaction system does not work well, the influent water is less or When it is large, it is easy to make the effect of biogas stirring the bottom sludge not good, the biog...
