PROBLEM TO BE SOLVED: To reduce the injecting quantity of hydrogen peroxide by injecting hydrogen peroxide to a water to be treated introduced into a reaction vessel in a water treatment system for decomposing organic compounds in the water to be treated. SOLUTION: The water treatment system is provided with the reaction vessel 1 in which a hydrogen peroxide decomposition catalyst 2 composed of a metal compound selected from the group composed of nickel, manganese, iron, copper and cobalt and activated carbon is packed, a water-to-be-treated introducing means 3 for introducing the water to be treated in the reaction vessel 1, a treated water discharge means 4 for discharging treated water from the reaction vessel 1 and hydrogen peroxide injection means 5a-5c for injecting hydrogen peroxide into the reaction vessel 1.
