２５３９５６）。The sludge blanket type anaerobic digestion tank forms a sludge blanket with sludge mainly composed of anaerobic bacteria and brings it into contact with waste liquid to perform anaerobic digestion, but the gas generated during digestion rises and becomes sludge. Since the blanket is disturbed and solid-liquid separation cannot be performed, the digestion reaction section and the solid-liquid separation section are divided. Some of these digesters have a solid-liquid separation section with an inverted triangular cross section using partition plates with an inclination of 45 degrees (USPN Q4).

問題点があった。However, in such conventional anaerobic digestion tanks, it is not possible to completely collect the generated gas, and some of the gas adheres to the solids and enters the solid-liquid separation section, resulting in the solid-liquid separation. There was a problem in that the separability deteriorated and sludge was mixed into the treated liquid.

The gas generated by the digestion is collected in the gas collection section, and the digestive fluid partially mixed with the sludge flows into the solid-liquid separation section. In the solid-liquid separation section, air bubbles attached to the sludge are separated and floated along the lower side of the inclined plate, and the sludge flows down along the upper side of the inclined plate, so that solid-liquid separation is efficiently performed. The digestive fluid separated in the solid-liquid separation section is taken out from the upper part of the digestion tank by the treated liquid removal means.
