The objective of this research was to study the treatment effect of micro-polluted water usingconventional activated carbon filter(CACF) andaeration activated carbon filter(AACF), test the effect of backwashing on the performance of carbon filters, and provide a reference for water plant upgrading. The removal efficiency of pollutants and the impact of backwash of AACF was studied and compared with CACF. The results showed that, with an influent turbidity of 0.67 versus 0.44NTU, CODMnof 2.48 versus 2.74mg / L, UV254of 0.045versus 0.045cm-1and NH4+-N of 0.15 versus 0.11mg / L, the removal effect of turbidity, CODMn, UV254,and NH4+-N are 36.19% versus 33.67%, 30.63% versus 21.53%, 23.06% versus 26.57% and 34.34% versus 19.62% . AACF improved the treatment of CODMn,and NH4+-N by 26.66% and 60%. Backwash is found to enhance the performance of AACF on CODMnwith the removal efficiency increases from the 25.82% to 29.75% after 2 hr backwash, and stabilizes at approximately 30% at the consequent 6 hrs; Backwash decreases UV254removal from 17.51% to 16.64% after 2 hr backwash, increases it to 19.64% to after 4 hr treatment, and drops to 13.44% after 8 hrs. Additionally, backwash has no significant effect on NH4+-N.
