Title:
PREVENTING METHOD OF POLLUTION OF WATER
Document Type and Number:
Japanese Patent JPH0747398
Kind Code:
A
Abstract:

PURPOSE: To surely prevent water pollution, to use a general-purpose device of rather simple structure, and to obtain significant effect in spite of low cost by setting silt which cause pollution by using a setting promoting means to the sea bottom in a water pollution generating area.

CONSTITUTION: A cylindrical positive electrode 10 is disposed in water just under the throwing point of silt which causes water pollution. A net-like negative electrode 12 is disposed around the positive electrode 10 to enclose the sea area for discharge. By energizing both electrodes 10, 12, soil particles electrified to have negative changes are withdrawn around the positive electrode 10 by an electric attracting force, then neutralized with cation released from the electrode 10, and lose repulsing force. Thus, aggregation and settlement of soil particles are promoted. On the other hand, the negative electrode 12 disposed to enclose the sea area for discharge acts to push back soil particles negatively electrified to the center part with repulsive force. Thus, flowing of the soil particles to the electrode 10 is promoted and diffusion of silt to the outer area of the sea area for discharge can be prevented.
