SOLID MATERIAL CAPTURE DEVICE AND SOLID MATERIAL CAPTURE METHOD

摘要

PROBLEM TO BE SOLVED: To efficiently capture a solid material such as a pollutant flowing in a water passage.SOLUTION: A solid material capture device 100 installed in a water passage for making a solid material flow together with water and capturing the solid material, comprises a shaft 110, a filter blade 120 having a filter function part 122 for forming a plurality of holes, erected in the radial direction from the shaft 110 and provided in a plurality by separating by a predetermined angle in the circumferential direction of the shaft 110, and rotary means 140 for rotating the filter blade 120 by rotating the shaft 110. The filter function part 122 of at least any one filter blade 120 among a plurality of filter blades 120 captures the solid material by becoming the positional relationship opposed to the water flowing direction, and the rotary means 140 rotates the filter blade 120 positioned in the water passage toward the upstream side of water.SELECTED DRAWING: Figure 2
