HIGH EFFICIENCY ANAEROBIC DIGESTION REACTOR OF ORGANIC WASTEWATER

摘要

The present invention relates to a reactor with high efficiency for anaerobically digesting organic waste water. According to the present invention, microorganism in the reactor can drift or be attached on the reactor to grow when biogas is produced. Therefore, contact between the microorganisms and raw water in the reactor is maximized; reaction time is reduced; and a methane recovery rate is increased. The reactor includes: a reactor main body including a waste water supplying part, a biogas discharging part, a second entrance, a first entrance to which a portion of an anaerobic digestion liquid, an anaerobic solution discharging part which discharges the anaerobic digestion liquid to a device for a next process; an agitator installed on a lower part of the reactor main body; a microorganism attachment device including a microorganism attachment device main body, a strainer, media to which the microorganisms are attached; a media cleaning device including an inlet, a joining part, and a plurality of discharging parts, which discharges the anaerobic digestion liquid; and a scum discharging prevention device including a scum prevention part and an anaerobic digestion liquid inducing part. According to the present invention of the present invention, removal of an organic material by the microorganisms in high density and efficiency of biogas production can be maximized by preventing the anaerobic microorganisms from being discharged to the outside.
