| 摘 要： | 利用自制的悬浮式活性炭纤维帘生物膜反应器处理模拟的氮污染水源水,考察了载体上生物膜驯化过程中生物相的变化和反应器内基质浓度的降解情况.试验结果表明,当进水中CODCr、NH3-N和TN的浓度分别达到37.1、1.79和2.04 sg/L时,出水中的浓度分别为15.3、0.39和0.48 mg/L,基本达到《地表水环境质量标准》（GB2002-3838）的Ⅱ类水质要求,去除率分别达到58.7％、78.4％和76.2％.与仅靠悬浮式活性炭纤维帘反应器吸附降解的去除率相比较,悬浮式活性炭纤维帘生物膜反应器的去除效果有明显提高.

| Abstract: | A homemade suspended activated carbon fiber curtain biofilm reactor was used to treat simulated nitrogen polluted raw water. The changes of the biological phase of the biofilm and the degradation of the substrate in the reactor during the biofilm domestication process were in- vestigated. The results of the test showed that, when the mass concentration of CODcr, NH3-N and TN in the wastewater were 37.1, 1.79 and 2.04 mg/L respectively, after the treatment, the corresponding indexes of the effluent water were 15.3, O. 39 and O. 48 mg,/L respectively, which met the second grade quality requirement of surface water quality standard（ GB 3838-2002）, and the removal rates reached 58.7% ,78.4% and 76.2% respectively. Compared with the removal rates of CODc,, NH3-N and TN by adsorption and degradation of suspended activated carbon fiber curtain, the removal rates by suspended activated carbon fiber curtain biofilm reactor were obviously higher. |
