The spore bacteria in the water body cannot withstand the instantaneous change from high pressure to low pressure, and burst, thereby achieving a sterilization effect; the primary pressure pump 1 provides initial power to the water flow, and then after forced oxygenation by the oxygen injection system 2, the water flow initially dissolves part of the oxygen and mixes with the undissolved oxygen. The gas-liquid mixture is simultaneously pressurized by the secondary pressure pump 3, and passes through the gas-liquid mixer 4 in a high-pressure and high-speed flow state, and the oxygen is fully dissolved to reach a saturated state. The remaining undissolved oxygen is separated by the gas-liquid separator 5 and discharged, and enters the low-pressure injection valve 6 as a high-pressure liquid (without gas).
