| 中文摘要 |
| 采用间歇式复合生物反应器处理人工配制的氨氮废水,进水NH3-N浓度约为160mg/L,HRT为12h,SRT为10d,NV可达0.15g/(L·d).重点比较了反应器中附着相和悬浮相微生物的硝化特性。结果表明,此时悬浮相和附着相微生物比NH3-N降解速率分别为0.68和0.53g/(g·d),附着相微生物的硝化活性稍低于悬浮相微生物。但当苯酚、喹啉、吡啶等毒性有机物存在时,附着相微生物抗有机物抑制能力明显强于悬浮相微生物。 |
| 英文摘要 |
| Artificial ammonia wastewater was treated with a batch hybrid biological reactor, concentration of influent NH3-N being about 160 mg/L, HRT being 12h, SRT being 10d, NV may reach 0.15g/(g·d).The emphasis was put on comparison between nitrification characteristics of the suspended microorganism and that of the attached microorganisms in the reactor. The results reviewed that the attached microorganism showed a little lower nitrification activity than the suspended microorganism, with specific degradation rate of NH3-N was respectively 0.53 and 0.68 g/(g·d),but higher ability of resistance to inhibition of toxic organic compounds for the attached microorganism was found, while phenol, quinoline or pydine existed. |
