<p>PROBLEM TO BE SOLVED: To provide a dredging slurry processing device capable of separating sand to be effectively utilized from the dredging slurry at a low cost during the time for carrying the dredging slurry to a slurry pond or the like, and to provide a dredging slurry processing method using the same. SOLUTION: Sand separating parts 1, 2, 3, 4 forming a part of a dredging slurry carrying passage and for separating the sand are arranged in plural series along a carrying route in a dredging slurry processing device. The sand separating parts 1, 2, 3 are provided with flow passages 15, 25, 35 for flowing the slourry from inflow ports 13, 23, 33 to outflow ports 14, 24, 34 and sand discharge ports 171, 271, 371 for discharging the sand settled on bottom parts 161, 261, 361 of the flow passages 15, 26, 35 and to be freely opened and closed. Flow speed of the dredging slurry flowing inside of the upstream side sand separating parts 1, 2 is set higher than the flow speed of the dredging slurry flowing inside of the downstream side sand separating parts 2, 3.</p> |
