きである。Embodiment 1 is a tank main body, in which a raw solution supply port 2 is provided at the bottom of the tank main body 1, and a treated liquid outlet 3 is provided at the top of the tank main body 1. Furthermore, in the upper part of the tank body 1, there is an outlet 4 for taking out the treated liquid and digestion gas, and a downward spout hole 6 in the tank below the outlet 4.
A liquid supply pipe 5 is provided, and the outlet 4 and the liquid supply pipe 5 are communicated through a circulation pipe 7.
8 is a pump. The circulation pipe 7 has an ejector 9
is provided, and the sludge mainly consisting of carriers carrying anaerobic bacteria accumulated at the bottom of the tank is pulled out from the sludge extraction port 10 provided at the bottom of the tank body 1 by the flow in the circulation pipe 7. , mixed into the circulating fluid. In addition to the ejector, a pump or the like may be used as a means for mixing the sludge into the circulating fluid. 11 is a gas vent provided at the top of the tank body 1.

る。 In the anaerobic digestion tank configured as described above, the raw liquid to be treated is supplied from the raw liquid supply port 2, the treated liquid flows out from the treated liquid outlet 3, and the entire liquid to be treated flows upward in the tank. It is formed. On the other hand, the treated liquid or digestion gas in the circulation pipe 7, or a mixed fluid thereof is transferred to the ejector 9.
The sludge mainly composed of carriers 12 such as vermiyquilite and vermiculite carrying anaerobic bacteria, which have settled and accumulated at the bottom of the tank, is pulled out from the sludge extraction port 10 and mixed in, and is mixed into the liquid supply pipe 5 at the upper part of the tank. The liquid is ejected downward from the ejection hole 6, facing the liquid to be treated which flows upward as a whole. As a result, the carrier falls into the liquid to be treated while flowing uniformly, increasing the bacterial cell concentration in the liquid to be treated, and digestion proceeds efficiently.
