), a discharge port (3) communicating with the upper part of the tank body (1), and an inclined plate (7JA, (7)B) installed in the tank (1).
上記構成にもとづく本発明の作用は下記の通シである。 The operation of the present invention based on the above configuration is as follows.

るＢＯＤ成分の嫌気性生物学的分解が起る。Inject the liquid to be treated into the lower part of the tank body from the injection port. The liquid to be treated ascends in the tank, and the sludge it contains settles out.
The supernatant liquid is discharged to the outside of the tank from the discharge port. At this time, the BOD component contained in the liquid to be treated is decomposed into methane gas by anaerobic biological decomposition, and the methane gas thus generated travels up the liquid to be treated and exits. The methane gas is mainly generated from the sludge layer with a high BOD value and disturbs the liquid to be treated as it moves upward within the liquid to be treated. The liquid to be treated is thus disturbed by the methane gas, but is rectified when passing between the inclined plates. Furthermore, a microbial film is formed on the inclined plate, and anaerobic biological decomposition of the BOD component contained in the material to be treated occurs at this location as well.

成分が更に分解され、ＢＯＤ成分の除去率も向上する。Therefore, in the present invention, since the liquid to be treated that is disturbed by the generated methane gas is rectified by the inclined plate, the sludge separation efficiency is increased, the entrainment of sludge into the supernatant liquid is prevented, and the inclined plate Since a microbial film is formed on the plate, this becomes a stationary phase and absorbs BOD contained in the processed material.
The components are further decomposed and the removal rate of BOD components is also improved.

るから略完全に行われる。In the above configuration, the liquid to be treated (5) is supplied to the bottom of the tank body (1) from the inlet (2), moves up inside the tank body (1), and overflows from the discharge port (3). During this time, the BOD component contained in the liquid to be treated (5) is decomposed anaerobically and the generated methane gas is guided by the gas separation plate (4) and ascends in the liquid to be treated (5) in the direction of arrow A, and is discharged as exhaust gas. It is discharged from the mouth (6). In addition, the liquid to be treated (5) is disturbed when the methane gas ascends, but it is rectified by the inclined plate (force A) to efficiently separate the sludge, and further rectified by the inclined plate (7) B to remove the accompanying sludge. If any, the liquid to be treated is efficiently separated.The rectification of the liquid to be treated by the inclined plate (7)B is almost completely effected because it is almost completely blocked by the gas separation plate (4) due to the influence of methane gas.

) overflows from the discharge port (3) after the BOD components and sludge are efficiently removed, but some of it flows through the reflux path (8).
The water is then refluxed to the injection port (2).
