The invention relates to a water treatment system based on the technology of simultaneously generating ozone and hydrogen peroxide, which includes a gas-water atomization mixing device, a discharge reaction device and a plurality of sewage treatment devices. The gas-water atomization mixing device generates a gas-water mixture with a certain pressure and enters the In the discharge reaction chamber of the discharge reaction device, a large amount of active substances such as ozone and hydrogen peroxide are produced in the discharge reaction chamber. The strong oxidizing gas enters the next sewage treatment device in turn and circulates in turn. In this water treatment system, strong oxidative active substances such as hydroxyl radicals, hydrogen peroxide and ozone generated by the discharge of the gas-water mixture can not only pass through their own oxidation, but also use the synergistic environment between a large amount of hydrogen peroxide and ozone generated by the discharge. Hydroxyl radicals are rapidly generated under the environment, so as to achieve more rapid and thorough degradation of high-concentration sewage.
