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 provided with a three-phase separator I chamber 3 and a mud gas riser 4. The mud gas riser 4 is connected with a three-phase separator II chamber 5 at the bottom of the three-phase separator II chamber 5. Expander, the upper part of the three-phase separator I chamber 3 is a reducer, the lower part of the three-phase separator I chamber 3 is a gas collection hood 13, and a settling sewage is arranged between the cylindrical gas collection hood and the outer cylindrical expander. The mud return joint 6 and the mud gas riser 4 are connected to the outer cylinder through the horizontal support plate 14, the water deflection baffle 7 is connected under the horizontal support plate 14, and the mud gas riser...

Description

technical field [0001] The invention relates to a high-efficiency 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 an...
