Abstract:
A purifying apparatus for purifying water flowing in a flowing direction over a flowing-water bed, comprising: a negative electrode plate to be disposed on the flowing-water bed; and a positive electrode plate to be disposed at an upper surface of the flowing water opposite to the negative electrode plate so as to have upstream and downstream end portions and opposing side portions with respect to the flowing direction of the water; said positive electrode plate being adapted so as to be dipped below the upper surface of the flowing water with floats being disposed at least at one of the upstream and downstream end portions of the positive electrode plate and the opposing side portions of the positive electrode plate; wherein structure is provided to position said positive electrode plate at a position of the upper surface of the flowing water opposite the negative electrode plate; and wherein said positive electrode plate and said negative electrode plate are provided with an electric field generator so that water pollution substances contained in the flowing water are oxidized and decomposed by a generation of high electric field pulses; and wherein said positive electrode plate has a concave curved face opposite to said negative electrode plate.
