摘要

Hydroxyl radical (center dot OH) water demand is a key parameter which impacts the design and operation of UV/H2O2 process for water treatment. Long-term monitoring of the center dot OH water demand in water sources used for drinking water production indicated significant seasonal variations of this parameter (1.59 X 10(4) to 4.98 X 10(4) s(-1)), which coincided with the occurrence of algal blooming events. Pilot-scale tests at a drinking water treatment plant confirmed that the UV/H2O2 process performance for contaminant removal is predictable when the center dot OH water demand is accurately determined through a validated experimental method. A predictive tool was developed to identify the optimum operating conditions of the UV system with the UV/H2O2 process and it was used to demonstrate the significant impact of seasonal variations of center dot OH water demand on the operating costs.
