To provide a dredge pump device which prevents agitated water with deposits at a water bottom from diffusing into and contaminating areas around the site of dredging and downstream regions during dredging, and also to provide a dredging system causing no environmental contamination.
The dredge pump device is provided with a jet pump 41 for sucking and discharging sludge at a water bottom using a high-pressure jet of water, and a cylindrical suction control cylinder 11 provided around the jet pump 41 for controlling a suction range. The deposits dredged by the dredge pump device are dried and cultured to refine methane gas. Electric power produced by driving a fuel cell with the methane gas is used as a drive source for a variety of dredging systems.
