A water discharge port 611 is arranged below the slag discharge port and above the second inclined tube settler 63 of the main reaction pool. The part of the main reaction pool above the second inclined tube settler 63 is connected to the water discharge port 611 through a pipeline arranged with a third electric valve 69. A second agitator 65 is fixedly arranged at the top of the main reaction pool. The output shaft of the second agitator 65 is connected to an aeration stirring mechanism 66.

Perforations corresponding to the air injection nozzles are arranged on the barrel core. The barrel core is connected to a rudder to control the rotation of the barrel core. The star-shaped stirring frame is butt-jointed to the air inlet pipe 67 arranged in the main reaction pool. In the specific implementation process, one end of the air inlet pipe 67 is sealingly connected to the bottom of the star-shaped stirring frame through a bearing, so that the air inlet pipe 67 is connected to the star-shaped stirring frame.

The sludge particles will settle on the surface of the sludge bed, and the gas will be collected.
