| Abstract: | This study investigated the start-up of high-rate UBAF pretreating for micro-polluted raw water of Xijiang River.The results showed that mature biofilm was formed in the filter after 12 days.The removal efficiency of ammonia nitrogen,COD achieved about 60% and 20%,respectively.And the gas water ratio was 0.1:1.Backwashing was conducted by air-water combination flush.When the system was operated steadily,the level of ammonia nitrogen,CODMn and other index could well meet the national standards for the daily ... |
