Ozone is insoluble in water. Therefore, after adding new mineral water to a water dispenser washed with ozone, there will be no ozone in the water.
Ozone, whose chemical molecular formula is O3, is also called triatomic oxygen and superoxide. It is named after its fish-like odor and can reduce itself to oxygen at room temperature. The specific gravity is greater than that of oxygen, and it is easily soluble in water and easy to decompose.
Since ozone is composed of oxygen molecules carrying one oxygen atom, it is only a temporary state. The carried oxygen atoms are not only used for oxidation, but the remaining ones are combined into oxygen and enter a stable state, so Ozone has no secondary pollution.
The gas is insoluble in water and insoluble in liquid oxygen, but soluble in liquid nitrogen and alkali. Liquid ozone decomposes slowly at normal temperatures and rapidly at high temperatures to produce oxygen, which can explode when impacted or rubbed.

Wastewater treatment effect of ozone
1. Coagulation-ozone oxidation technology
Coagulation-ozone oxidation technology It uses ozone oxidation technology to treat wastewater under the condition of adding coagulant. Ozone can change the properties of suspended solids in the water, thereby changing the removal effect of the coagulation operation unit. This method can make the suspended particles in the water larger and turn the dissolved organic matter into mixable gel particles, thus reducing the amount of coagulant. quantity and reduce chemical consumption. Ozone-biochemical method
There have been many reports in recent years about the use of ozone catalytic oxidation combined with biological activated carbon filters to treat wastewater patents. It is collectively referred to as the use of ozone to pretreat wastewater to destroy refractory organic matter in the water and improve biodegradability. The technology of reusing activated carbon biological filter for further treatment. This technology makes full use of the strong oxidizing properties of ozone and the cost advantage of biological filters. The combination of the two has a good treatment effect.
2. Ozone-membrane treatment technology
A patent has published an ozone catalytic oxidation-ceramic membrane filtration depth treatment coking wastewater system, which is combined with ozone catalytic oxidation and ceramic membrane separation. The application of powder catalyst in dynamic reactor is realized.
The reaction system ensures segmented ozone oxidation and catalytic ozone oxidation in a single reactor, which reduces the mass transfer resistance in the individual ozone oxidation and catalytic ozone oxidation processes, and improves the utilization rate of hydroxyl radicals and organic matter. removal rate, and finally achieved the COD, color and turbidity standards of the effluent from the advanced treatment of coking wastewater.
3. Direct ozone aeration treatment
Adopt the two-stage biochemical effluent treatment method through two-stage ozone catalytic oxidation, that is, the bottom of the primary ozone catalytic oxidation tank and the secondary ozone catalytic oxidation tank Connected, the secondary ozone catalytic oxidation pool is equipped with a main water outlet to achieve energy saving and cost reduction. It can increase COD removal rate by 20%.
A patent has published an ozone treatment system for reducing the COD concentration in organic amine wastewater, using ozone oxidation to reduce COD in organic amine wastewater. This system divides the ozone reaction pool into three contact oxidation reaction pools: front, middle and back, which are divided by partitions, and the volumes of the three contact oxidation pools decrease in sequence. This method is used to conduct oxidation treatment in contact oxidation ground to achieve the treatment of wastewater containing organic amines and meet the discharge standards.
