PROBLEM TO BE SOLVED: To remove contamination substances such as organic matters and inorganic matters in water by simultaneously applying an oxidation work, are reduction work, an electrolytic corrosion work, an electric neutralization work and a flotation work, and the like, with respect to water. SOLUTION: Granular media 4 are provided between a minus and a plus electrodes 2,3 in an electrochemical tank, and an electric field work is formed between the minus and plus electrodes 2, 3 so that electrical chemistry is utilized. Between the contamination substances in the raw water in the tank and the granular media 4, an electron transfer mechanism is generated. Fine air bubbles generated by utilizing the oxidation-reduction reaction and an aggregation work or the oxidation-reduction reaction alone, float flocks generated by the aggregation work on a water level and the flocks are removed, and simultaneously, the organic and inorganic contamination substances in the waste water are removed.
