PROBLEM TO BE SOLVED: To solve the problem that leakage of turbidity caused by a tidal current etc. occurs in the case of a conventional method for accelerating sedimentation of polluted particles in an anti-pollution frame.SOLUTION: In this method for accelerating the sedimentation of the polluted particles in the anti-pollution frame, the anti-pollution frame 1 for use in grab dredging is interiorly finished with a void material 2 with a porosity of 80-95%; turbid water in the anti-pollution frame passes through the void material; and thus, the sedimentation of the polluted particles is quickened by accelerating the agglomeration of the polluted particles and the formation of a flock of them in the turbid water. |
