Optimization of ozone with ozonolysis catalyst
Ozone treatment of wastewater speed, high efficiency; Its processing technology is relatively simple, easy to operate; And it no secondary pollution , the remaining gas after ozone treatment can be converted into oxygen, no secondary pollution.
However, the concentration of ozone is too high to cause harm to the human body, in the process of sewage treatment, when the ozone concentration exceeds a certain level, it will strongly stimulate the human respiratory tract, and then cause headaches, ozone may also destroy vitamin E in the human skin, vitamin E is an important nutrient to maintain retinal health and vision. Long-term exposure to high concentrations of ozone may not only lead to vision loss or blurring, but also accelerate the aging process of the eye leading to skin aging, wrinkling and dark spots. The harm of ozone to the human body should not be ignored, especially its impact on the nervous system, which may lead to dizziness and headache and other symptoms; When the ozone concentration exceeds 140 micrograms/cubic meter, people will feel a sore throat and cough, this irritation may not only cause chest tightness and sore throat, but also may aggravate upper respiratory diseases.
Therefore, in the process of treating sewage with ozone, ozone decomposition catalyst can be added. Ozone catalyst will adsorb ozone molecules in wastewater or air, so that ozone molecules gather in the catalyst, which increases the contact chance of ozone and the active components of the catalyst, and can accelerate the catalytic reaction. Under the action of
ozone catalyst, ozone molecules adsorbed on the surface will decompose and form strong oxidizing free radicals, which can react with organic pollutants more efficiently, will form new free radicals, and the newly generated free radicals will continue to react with the surrounding organic pollutants. It can quickly degrade organic pollutants in wastewater or air into harmless substances, such as carbon dioxide, water, etc.
