Sterilizing Effect of Ozone in Water Cooling Circulation Treatment

Using sulfate-reducing bacteria,iron bacteria and heterotrophic bacteria as paramaters,the sterilization effect of ozone on circulating cooling water of petrochemical plants was studied.The affecting factors of ozone dosage,disinfection time,temperature and pH were evaluated.When the ozone dosage was 100 mg / L and the sterilization time was 16 min,99.9% of the microbes could be sterilized,and the circulating cooling water quality standard of chemical enterprises could be satisfied.Temperature and pH of water almost had no effect on the treating.
