Domestic Sewage Treatment Plant UV Ozone Equipment
Till the ozone enter the field of water treatment, more and more show its superiority.
But there are still some problems in operation:
- Because thinking about the cost of ozone generator & mixing reaction tower, many users do not choose it.
- It is few kind of Gas-liquid mixing device, and low mixing efficiency, about 40-70% ozone can not be mixed in water. So for better efficiency, the suppliers should increase ozone output which will increase the cost.
- Hard to ensure the quality of mixing device, reaction tower and other components if buy them separately.
For several years researching, now we use UV & Ozone together for improving ozone dissolution ratio.
UV-O3 Disinfection system combined with ozone and ultraviolet.
1. Theory evidence:
Scientists have discovered that added UV in ozone disinfection system can stimulate activity of ozone, and catalyze ozone & water molecules to create plenty of hydroxyl radical (OH-). OH- is active material which was produced by reaction of ozone with water.
The oxidizing ability of OH- is 100 times higher than hypochlorite (OCI-).
The sterilization ability of OH- is 3000 times higher than hypochlorite (OCI-).
The sterilization ability with UV & Ozone is 1-2 times higher than use ozone individual.
2. System Structure
A. Use booster pump, injector and reaction tower for ozone mixing in water, then water return to tank. Because the irradiation of UV has greatly increased generate of OH-, OH- speeds up the oxidation and sterilization efficiency for water.
B. UV-O3 system, because it using UV, it not only have an excellent effects of sterilization & oxidation under low ozone output working condition, but also can avoid risk of high ozone concentration in aquaculture. With using UV for small size of reaction tower, there is no need to use activated carbon for ozone destructor which can save much cost.
C. UV-O3 can reduce the dosage of Chlorine. If the efficiency can match with requirements of sterilization and oxidation, the amount of Chlorine could be further decreased, combined Chlorine, free Chlorine can be respective lower than 0.2 mg/L, 0.4 mg/L in water. The Chloramines and THM have been substantially reduced to a certain extent. It will be the important part for meet with the requirements of environmental protection.
D. In UV-O3 system, OH- has strong oxygenolysis ability for organic pollutants. The production of OH- and its reaction with organic pollutant only can be carried out under UV.
E. Using UV-O3 system can save ≥40% cost than use ozone only.
