System and method of reducing organic contaminants in feed water |
摘要 |
A zero liquid discharge (ZLD) power plant ( 20 ) includes an advanced oxidation system ( 72 ) for reducing contaminants in source water ( 70 ) to form feed water ( 40 ) for a boiler ( 24 ). The system ( 72 ) includes an ozonation module ( 86 ) for applying high concentration ozone to the source water ( 70 ) to form a mixed stream ( 104 ), an ozone reactor ( 92 ) in which the mixed stream is retained ( 104 ) under pressure, an ultraviolet reactor ( 98 ) downstream from the ozone reactor ( 92 ) for enhanced contaminant reduction, and a retention tank ( 103 ) downstream from the reactor ( 98 ). In one configuration, the source water ( 70 ) is evaporator distillate from an evaporator ( 52 ) that recycles cooling tower blowdown 30 . The system ( 72 ) achieves organic contaminant reduction at total organic carbon (TOC) levels of less than three hundred parts per billion.
