The implementation principle of the first embodiment is as follows: the sewage enters the first sludge removing chamber 3 and the second sludge removing chamber 5 from the water inlet pipe 6, and the sewage passes through a sludge bed (not shown in the figure) to generate methane. The biogas and the sewage rise, and the biogas hits the lower end surface of the baffle 7, enters the exhaust chamber 4 from the exhaust port 8 along the baffle 7, and then flows out of the exhaust chamber 4 from the exhaust pipe 19. And sewage touches the lower end face of the baffle 7, and sludge is impacted to be separated from the sewage and fall to the bottom end of the cylinder body 1. The sewage flows upward into the first guide groove 11 and then flows along the first guide groove 11 into the exhaust chamber 4. When the sewage in the exhaust chamber 4 is fully accumulated to the diversion port 14, the sewage flows into the second diversion trench 12 from the diversion port 14, and finally flows out of the cylinder body 1 from the water outlet pipe 15. In the whole process, the end cover 16 is opened, the sewage is observed and detected, and the methane in the cylinder body 1 cannot overflow from the cylinder body 1.

Example two: referring to fig. 4, the difference compared to the first embodiment is that: an observation window 20 is embedded in the end cover 16, a water level line 21 is fixed on the side wall of the second diversion trench 12 in the length direction, the water level line 21 is distributed along the height direction of the cylinder body 1, and the diversion port 14 is detachably connected with a filter screen 17. A second diversion trench 12 is installed at the upper end of the second desilting chamber 5, the opening of the second diversion trench 12 is positioned on the top surface of the second desilting chamber 5, and the second diversion trench 12 is provided with a structure the same as that of the first diversion trench 11.

The second embodiment is implemented according to the following principle: the water level line 21 in the second diversion trench 12 is observed through the observation window 20, so that the treatment condition of the sewage can be known in real time. The sewage flows out of the second diversion trench 12 in the first silt removing chamber 3 and the second silt removing chamber 5 simultaneously, so that the flow speed of the sewage is increased, and the silt removing speed is increased. When sewage in the exhaust chamber 4 enters the second diversion trench 12 through the diversion port 14, sludge in the sewage is blocked by the filter screen 17, so that sludge in the second diversion trench 12 is reduced, the second diversion trench 12 is convenient to clean, and the sludge removal effect is improved.

The embodiment of this specific implementation mode is the preferred embodiment of the present invention, not limit according to this the utility model discloses a protection scope, so: all equivalent changes made according to the structure, shape and principle of the utility model are covered within the protection scope of the utility model.
