This experiment proposed aerated active sand biofilter (AASB) to strengthen biological effects in sewage treatment. It explores the method of biofilm accretion and start-up by AASB, then inoculated by active sludge and incremental flow rate to accelerate the start-up ,when HRT is 3h, the temperature is 21.0 ~ 26.5?, gas-water ratio is 3:1, biofilm accretion and start-up of AASB can be completed in 23d.At this point removal rates of COD,NH3-N and turbidity are stabilized at 70%,38%,92%, which are better than common active reactor to be a new way to treatment domestic sewage.
