| Abstract: | The improved rotating biological contactor was developed to treat the domestic sewage. The disks were changed as a rotating cage, in which granular active carbon were added as carriers. The results showed that in the conditions that the rotary speed was 15rpm, HRT were 10, 8, 6 and 4.5 respectively, average influent COD was 223mg/L, the average effluent COD were 15. 6, 17. 9, 23. 4 and 28. 2mg/L respectively, the average removal rates of COD were 93. 0%,91. 9%, 89. 5% and 86. 6% respectively; the average irrfluent NH3-N was about 22mg/L, the average effluent NH3-N were 0. 32, 1.13, 2. 30 and 5.71mg/L respectively and the average removal rates of NH3-N are 98.5% , 94. 8% , 89.7% and 74.6% respectively. |
