Application of Micro-Flocculation Direct Filtration for Reservoir Water Derived from Yellow River
Aiming at the water quality characteristics of low turbidity and low temperature of the Reservoir Water derived from Yellow River(RWDFYR), the technology of micro-flocculation direct filtration for RWDFYR was studied. The effluent index such as CODMn, UV254, TOC and turbidity was investigated under the different filtration rate conditions of 4m/h, 5m/h, 6m/h, 8m/h and 10m/h. The results show that the value of removal efficiency of turbidity reached at 98%, and the value of removal efficiency of organic matter was 40% also. In this study, the removal effect was good under the filtration rate of 6m/h. Moreover, the removal effect of different filter layers was also carried out. Finally, it concluded that the backwashing cycle of filter layer should not exceed 3days.
