Research on the Treatment for Ozone-Flocculation Filter from Yellow River

This paper mainly based on the new processes of ozone-floating filter and ozone floatation which were tested in the water from the Queshan Reservoir. The process of ozone floating filter stated that little influence ccurred when the raw water was pre-treated by the ozone. UV254(Ultraviolet Rays)was removed in large amount (76.47%) if the ozone oxidation had been adopted. The removal rate could achieve 100% when the air flotation and activated carbon filtration were used. Ozone oxidation has good effects on the removal of COD (Chemical Oxygen Demand)
_Mn
, the total removal rate was increased 7.0% in average rather than the technology without ozone, and the final content in the effluent was 1.87mg/L. in the new technology, ozone flotation did little job to decreasing turbidity. And the great progress was the removal of UV254 through the strong ability of oxidation. The removal rate was increased 9.80% in average rather than floating filter technology.
