step two: the gas enters the water washing tank (5) through the guide pipe (15), the water washing tank (5) is filled with washing water, the bottom end of the guide pipe (15) is buried, sulfide in the gas and water are dissolved, then the gas rises to enter the communicating pipe (16), the communicating pipe (16) enters the dissolving tank (6), span80 solution is filled in the dissolving tank (6) and the bottom end of the communicating pipe (16) is buried, after the gas enters, methane and Span80 solution contained in the gas are dissolved, then the gas is sucked into the filter element (18) through the hot discharge fan (17) in the discharge tank (7) to be subjected to water absorption and filtration again, and then the gas is discharged;
step three: the driving motor is used for driving the rotating shaft to rotate, the two groups of rotating plates (13) are driven to be opened, sludge falls to the sludge filter plate (14) from the bearing box (11), large-particle impurities in the sludge are filtered by the sludge filter plate (14), the sludge enters into the sludge conveying belt (19) inside the conveying box (1), an activating agent is fed into one end of the integrated pipe (22), the integrated pipe (22) distributes the activating agent to the dispersing spray heads (24) on the inner sides of the fixed frames (23) through the liquid inlet pipes (26), the rotating damping rotating shaft (25) adjusts the inclination of the dispersing spray heads (24), the agent is sprayed on the surface of the sludge, and the sludge is returned to the sludge treatment pool to finish the operation.
