The ozone generator converts the oxygen delivered by the oxygen generator into ozone gas under the excitation of high-voltage electric energy, and delivers the ozone gas to the ozone water preparation device.
The ozone water preparation device is connected with the negative pressure pump, and the oxygen conveyed by the oxygen generator, the ozone conveyed by the ozone generator and the water mist conveyed by the magnetization atomization device are physically mixed in a negative pressure or vacuum state to form high-concentration ozone water.
In the embodiment, the magnetized high-pressure atomized water + ozone gas + oxygen gas are utilized to synthesize the high-concentration ozone water in a negative pressure or vacuum state, and compared with the traditional ozone water preparation method, the ozone water preparation process has the main advantages that:
the conventional ozone water preparation method adopts ozone gas to be mechanically mixed with water, for example, by a venturi tube, an aeration pump, etc., and has the following problems:
the first problem is that: the ozone gas has low utilization rate, only about 20 percent of the ozone gas can be combined with water, and the rest about 80 percent of the ozone gas can escape from the water and is discharged into the atmosphere, so that the electric energy is wasted, and the discharged ozone gas can pollute the atmosphere;
the second problem is that: the binding force between ozone molecules and water molecules is weak, the half decay period of ozone in water is only 30-60 minutes, and the ozone cannot be stored for a long time;
the third problem is that: the prepared ozone water has low concentration and can not be prepared into high-concentration ozone water;
the fourth problem is that: in the ozone water preparation process, the amount of ozone gas discharged to the air often exceeds the national requirements for ozone discharge standards.
Compared with the traditional method, the ozone water preparation process of the embodiment comprises the following steps:
the method has the advantages that: the ozone gas has high utilization rate, the ozone gas prepared by the ozone generator can completely enter water, energy is saved, and no pollution is caused to the atmosphere;
the advantages are two: when ozone water is prepared, the binding force between ozone molecules and water molecules is strong, the half decay period of ozone in water can be increased to 300-600 minutes, and is about 10 times longer than that of the traditional ozone water, and the half decay period is prolonged, so that the storage of the ozone water and the application of the ozone water in a new field are favorably expanded;
the advantages are three: the prepared ozone water is high in concentration, and the ozone concentration of the traditional ozone water is generally 3-10 ppm; the ozone water prepared by the embodiment has the ozone concentration of 20-80 ppm, and can be used for sterilizing and disinfecting sewage treatment or high-risk space in high-difficulty fields;
the advantages are four: in the embodiment, when ozone water is prepared, because the molecular interfaces of ozone molecules and water molecules have strong binding force under a negative pressure state and are not easy to separate from each other, the ozone molecules cannot be discharged from water under a non-stirring state, and therefore, the concentration of ozone in the air can meet the requirement that the leakage concentration of ozone discharge specified by national standards is less than 0.1ppm in the production and application processes of the ozone water;
the advantages are five: in the ozone water preparation process, pure oxygen is added in the negative pressure state, the chain reaction of ozone molecules is facilitated, the ozone concentration is improved by 2-5 times, and meanwhile, the residual oxygen and water molecules are tightly combined in the physical state in the reaction, so that oxygen-enriched drinking water is formed, which is not available in the traditional process.
The ozone water producer delivers the produced high concentration ozone water to the hydroxyl radical generator for producing the hydroxyl radical aqueous solution. Specifically, in the present embodiment, an ultraviolet lamp is incorporated in the hydroxyl radical generator to emit ultraviolet rays. Under the irradiation of ultraviolet rays, ozone is decomposed to generate active hydroxyl radicals, and then hydroxyl radical aqueous solution is formed and conveyed to a hydroxyl radical aqueous solution storage tank for storage.

The two sets of hydroxyl radical aqueous solution generating devices can be mutually backed up and alternately operated and can also be simultaneously operated.
Since the hydroxyl radical aqueous solution decays more than 10 times slower than the concentration of the conventional ozone water, it can be stored in the storage tank for a certain period of time. In order to expand the application field of the system, the present embodiment may be configured with a water outlet pipe capable of outputting the hydroxyl radical aqueous solution to the outside on the hydroxyl radical aqueous solution storage tank, so as to provide the hydroxyl radical aqueous solution to the user for daily disinfection or sewage treatment.

And a water pump M3 and a water solution outlet valve K3 are arranged on the other liquid outlet pipe, and the other liquid outlet pipe can be externally connected with a sewage treatment pipeline and is used for conveying the hydroxyl radical water solution to water mixing devices such as an aerator pipe of a sewage treatment system for sewage treatment.

When drinking water needs to be supplemented to the water storage tank, the controller detects the water quality condition of the raw water after physical purification through the water inlet detection device, and judges whether the hydroxyl radical aqueous solution needs to be utilized to sterilize and disinfect the inlet water according to the water quality condition. If necessary, the controller controls the second solenoid valve K2 to open, and injects the hydroxyl radical aqueous solution stored in the hydroxyl radical aqueous solution storage tank into the mixer MIX to be mixed with the inlet water into the mixer MIX. Meanwhile, the mixing proportion of the hydroxyl radical aqueous solution and inlet water can be adjusted by adjusting the opening degree of the second electromagnetic valve K2, so that the device is suitable for different water quality conditions.

In the hydroxyl radical sterilizer, hydroxyl radicals are utilized to kill pests in the water, reduce the Chemical Oxygen Demand (COD) in the water, decompose pesticide residues, degrade harmful organic matters in molecular level to form micromolecule oxygen-enriched water which is easy to be absorbed by human bodies, and then convey the micromolecule oxygen-enriched water to a micromolecule mineral adder.
