Abstract

The invention relates to an anaerobic reactor, in particular to a double-path circulation full-mixing type anaerobic reactor, mainly comprising a reactor body, a feeding device, a circular stirring device, a drainage device, a safety protection device, an effluent device, a heating device, a detection control device, a methane collection device and the like. The double-path circulation full-mixing type anaerobic reactor is provided with an internal circulation stirring device and an external circulation stirring device; the two circular stirring devices are combined to stir materials, internal circulation stirring plays a main role, while external circulation stirring plays an assistant role, so that the reactor has the characteristics of effectively trapping slurry, having high yield, obviously reducing operation cost, remarkably improving effluent quality and the like.

Description

technical field [0001] The invention relates to a two-way circulation fully mixed anaerobic reactor, which belongs to the technical field of anaerobic biological treatment. Background technique [0002] To improve the effect of anaerobic biological treatment, in addition to providing a good growth environment for microorganisms, maintaining a high sludge concentration in the reactor and maintaining a good mass transfer effect are also key elements. In the first-generation anaerobic reactor represented by the anaerobic contact process, the sludge retention time (SRT) and hydraulic retention time (HRT) are roughly the same, and the sludge concentration in the reactor is relatively low. If you want to achieve a better treatment effect, the wastewater usually stays in the reactor for several days to dozens of days. The second-generation anaerobic reactor represented by the upflow anaerobic sludge bed reactor wastewater anaerobic biological treatment technology (USAB) relies on ...
