Abstract

The invention discloses a methane air floating anaerobic reactor, which comprises an anaerobic bioreactor body (3), wherein a waste water inlet pipe (1), a waste water distribution device (111), a sludge expanding bed region (2), a three-phase separator (4) and a clarified water outlet pipe (5) are sequentially distributed in the anaerobic bioreactor body (3) from bottom to top; an anaerobic air floating reaction region (16) is arranged above the three-phase separator (4), and is provided with a methane outlet pipe (8) and a return pipe (51) which extend outside the anaerobic bioreactor body so as to be connected with a dissolved air water preparation system (9); the dissolved air water preparation system (9) is connected with an air bubble releaser (12) above the three-phase separator (4) through a dissolved air water inlet pipe (10); and an air floating protection cover (11) is arranged on the air bubble releaser (12). The methane air floating anaerobic reactor integrates anaerobism, condensation, air floatation, drossing, sedimentation and sludge scraping into a whole. The COD (Chemical Oxygen Demand) removal efficiency is increased by 50 percent, and the equipment investment is reduced by 30 percent.

Description

technical field [0001] The invention relates to environmental protection equipment, in particular to an anaerobic bioreactor, in particular to a methane floating anaerobic reactor. Background technique [0002] Anaerobic contact method, also known as anaerobic biofilm method, is an anaerobic biological suspension growth treatment process. Microorganisms that stabilize wastewater, effluent, are removed from treated water by sedimentation or other methods and are either left in the treatment process or sent back to the treatment process to expedite treatment. During treatment, the raw wastewater is completely mixed with the return sludge, and then digested in an anaerobic reactor. The digested mixed solution is separated from solid and liquid in a clarifier or vacuum flotation equipment, and the supernatant effluent can be further treated. The sinking anaerobic sludge is returned to the influent wastewater as an inoculum to speed up the treatment. Due to the low synthesis ra...
