といった不都合が防止される。[0008] SS in the inflowing wastewater is mixed with a sludge bed mainly composed of anaerobic microorganisms, but except for SS which has strong adhesiveness, SS has finer particles and smaller sedimentation property. Gather higher. When the wastewater continues to flow in and the SS layer expands and rises in the reaction section to reach the upper part of the umbrella-shaped member, the hydrostatic pressure causes it to be extracted from the extraction pipe provided at the top of the umbrella-shaped member. The phase separation portion is not reached, and the inconvenience of clogging the three phase separation portion and lowering the processing capacity is prevented.

Further, although the anaerobic microorganisms do not mix with the SS layer, some of them float while being stirred by the gas, but inside the umbrella-shaped member, the stirring of the gas disappears, and the sludge bed is suspended by its own weight. Since the microorganisms fall, the microorganisms do not move laterally (horizontally) to be extracted from the extraction tube and reduced.

る。Further, SS in the inflowing wastewater is mixed with the sludge bed 7 mainly composed of anaerobic microorganisms. However, except for SS having strong adhesiveness, SS has finer particles and smaller settling property. Collect above the sludge bed 7. Then, as the wastewater continues to flow in, as shown in FIG. 1, when the SS layer expands and rises in the reaction section 6 to reach the upper part of the umbrella-shaped member 9 of the gas collecting member 8, the hydrostatic pressure of the umbrella causes the umbrella to move. It flows into the extraction pipe 10 provided at the top of the member 9 and is discharged to the SS storage tank 11 provided at the end thereof. Therefore, this SS does not reach the three-phase separation unit 3, and the inconvenience of clogging the three-phase separation unit 3 and lowering the processing capacity is prevented.

The gas is collected by the umbrella-shaped member 9 of the gas collection member 8 and collected at the top thereof, passes through the gas guide pipe 12 connected to the top and reaches the three-phase separation unit 3, where it is separated. The gas is discharged from the gas discharge pipe 4. Most of the gas G discharged from the gas discharge pipe 4 contains methane gas as a main component, and can be effectively used such as being used as a fuel gas. In addition, the anaerobic microorganism is SS
Although it does not mix with the bed, the gas is partly stirred and floats along with it, but the gas G is no longer stirred above the gas collection member 8 and falls onto the sludge bed 7 due to its own weight. Since the anaerobic microorganisms are then returned again, the anaerobic microorganisms are prevented from moving laterally (horizontally) and being extracted from the extraction tube 10 to be reduced.

In addition, the gas G generated in the reaction section 6 is collected and SS
By providing the umbrella-shaped gas collecting member 8 for extracting the gas, it is possible to prevent the SS layer from rising and prevent the processing performance of the three-phase separation unit 3 from being deteriorated. Therefore, it is possible to prevent anaerobic microorganisms from being extracted together with SS. Further, when the reactor 1 is a UASB reactor, the above-described effects are remarkably exhibited, but the present invention can be applied as it is because other upward-flow anaerobic reactors often form granules. In addition, a part of the granules of the anaerobic microorganisms adheres to the gas and rises in parts other than the umbrella-shaped member 9 to be separated from the gas in the three-phase separation unit 3, and then settles to separate the umbrella-shaped member 9. Even if it falls on the upper surface, it will fall further downward along the inclination, so that it will be deposited on the umbrella-shaped member 9 or from the extraction pipe 10 to S.
There is no inconvenience that it will be extracted together with S.

At the upper end of the plate 2, an inclined plate 14 that serves as a gas collecting member 8 is provided in a tank 13
It is installed so as to incline diagonally downward on the a side, and this tank 1
The sludge bed 7 is formed at the inner bottom portion of 3a, and the wastewater introducing pipe 2 is directly connected to the sludge bed 7. That is, in this embodiment, the inside of the vertical reactor 1 is divided into two tanks 13a and 13b by the partition plate 2, one tank 13a is used as the above-mentioned sludge bed 7, and the other 13b is used as the above-mentioned SS tank.

It is different from the above-mentioned invention in that it is not introduced into the 3b side but is directly introduced into only one tank 13a side and the other layer 13b is used as a storage tank for SS. That is, the layer of SS in the wastewater is accumulated on the side of the tank 13a, so that it gradually rises, and when it exceeds the height of the top of the inclined plate 14 of the gas collection unit 8, the tank 13b adjacent to the tank 13a. And will be stored temporarily. Then, the discharge pipe 15 is provided in the tank 13b and the SS is withdrawn as necessary, so that the accumulation of SS in the reactor 1 is prevented in advance.
