Problems solved by technology
For example, the EGSB reactor requires liquid reflux, which not only increases power consumption, but also makes the reactor fully mixed, making it difficult to further improve the treatment efficiency and effluent quality
IC reactor is prone to short flow before internal circulation is realized, and operation control is difficult

Embodiment Construction
[0010] As shown in the attached figure, the anaerobic bioreactor has a reactor body, and a water inlet pipe 1 and an upflow reaction chamber 2 are arranged at the lower end of the reactor body. The cylinders are connected, and the outer cylinder of the sedimentation chamber 11 is equipped with a three-phase separator I chamber 3 and a mud gas riser 4 connected to each other. The mud gas riser 4 is connected with a three-phase separator II chamber 5 and a three-phase separator II. The bottom of chamber 5 is the expander, the upper part of the three-phase separator I chamber 3 is the reducer, the lower part of the three-phase separator I chamber 3 is the gas collection hood 13, the gas collection hood and the expander at the lower end of the outer cylinder of the precipitation chamber 11 Settled sludge return joints 6 are arranged between them, and the mud gas riser 4 is connected to the outer cylinder through a horizontal support plate 14. The horizontal support plate 14 is conn...

Description
technical field [0001] The invention relates to an anaerobic bioreactor. Background technique [0002] Anaerobic biological treatment technology is the process of converting organic pollutants into biogas by using the metabolism of microorganisms under anaerobic conditions, so as to purify sewage. Compared with aerobic biological treatment, anaerobic biological treatment has the characteristics of low energy consumption, low sludge output, and the ability to recover clean energy (biogas). It is one of the effective means to realize circular economy and has broad application prospects. [0003] With the deepening of people's understanding of anaerobic biological processes and the popularization of the application of anaerobic biological treatment technology, anaerobic bioreactors have also been better developed. So far, anaerobic bioreactors have been developed to the third generation. The first generation of anaerobic bioreactor is represented by ordinary anaerobic digeste...
