Ozone has a toxicity, ozone concentration in the air to 0.1mg/m3 when the human eyes, nose, throat and respiratory tract irritation in the 0.01-0.02mg/m3 can be smelled when the odor; therefore, in the ozone equipment should be set up between the ventilator in the event of leakage of ozone can be discharged in a timely manner. Ozone is heavier than air, the ventilator should be installed near the ground.
The ozone pipeline and ozone equipment must be sealed to prevent leakage
Before the operation of the equipment should be checked for leakage, once the leakage occurs in the operation of the ozone generator should be immediately turned off the power supply, open the exhaust fan to discharge the ozone, and then overhaul.
High-efficiency ozone generator for high-voltage discharge equipment, should be set up grounding device, grounding resistance should be less than 4 ohms. Operation should be in strict accordance with the instructions for use of the equipment and the requirements for the use of electrical appliances.
Tail gas treatment or tail gas recovery device must be set up, the ozone tail gas discharged after the reaction must be decomposed and destroyed or recycled to meet the emission standards, otherwise it will pollute the atmosphere.
The use of ozone disinfection of sewage, pretreatment is very important, often due to the degree of pretreatment is not enough to affect the effect of ozone disinfection, the degree of sewage treatment to be determined by technical and economic comparison. Sewage disinfection is best after secondary treatment and then use ozone disinfection. This can reduce the amount of ozone dosage, reduce equipment investment costs and operating costs.
