The utility model discloses mainly belong to the sewage treatment field, concretely relates to high energy oxygen generating device and water processing system. The device is including casing and cavity, the cavity by the internal surface of casing constitutes, high pressure rivers and gas mixing get into the cavity, the structure of cavity makes rivers and gas high -speed vortex in the cavity move, takes place gaseous cutting production high energy oxygen. The utility model discloses provide a water processing system based on this high energy oxygen generating device simultaneously, this water processing system is portable, can become to accord with the water of index automatically with sewage treatment. This water processing system only consumes the electric energy, and operation mode isintermittent type formula, no other fees moreover. The simultaneous processing water yield is big, consumption of electric energy is few, with low costs. There are not other investment costs. The simple easily maintenance of equipment reduces expense cost and the human cost moved.
