| 摘 要： | 采用自主设计的序批式生物膜反应器(SBBR)处理南方地区城市污水,在常温(25～27℃)条件下,pH值7.2～7.6,通过恒定低曝气量实现了稳定的亚硝酸型同步硝化反硝化(SND)。试验还考察了ρ(C)/ρ(N)对SBBR系统SND的影响。结果表明:在SBBR反应器中处理城市污水实现SND的较为适合的ρ(C)/ρ(N)在5～8,亚硝酸氮积累率在85%以上,TN去除率可以达到80%以上。 |

| Abstract: | Simultinious nitrification denitrification via nitrite was steadily realized in sequencing biofilm batch reactor (SBBR) designed independently with urban sewage in south China at normal temperature(25—27 ℃) and pH:7.2—7.6 of controlling low oxygen. The effect of C/N ratio on SND was examined. The results indicated that C/N ratio realizing SND in SBBR with urban sewage was 5—8. Nitrite nitrogen accumulated rate was over 85% and TN removal efficiency of 80% could be achieved. |
