Abstract
A purifying apparatus for purifying flowing water includes a negative electrode plate disposed on a flowing water bed and a positive electrode plate disposed at an upper face opposite to the negative electrode plate, wherein the positive electrode plate is adapted to be dipped below a water surface of the flowing water with floats being disposed at least at upstream and downstream end portions or opposing side portions of the positive electrode plate in a flowing direction of the flowing water. A structure is provided for positioning the positive electrode plate at a position opposite the negative electrode plate. Also, as necessary, a vertical-movement structure is provided to allow vertical movement of the positive electrode plate and of a gas collecting unit. The positive electrode plate and the negative electrode plate are provided with an electric field generator.
