| 摘 要： | 采用自主设计的序批式生物膜反应器(SBBR)处理城市污水,在常温(25～27℃),pH值7.2～7.6条件下,通过恒定低曝气量实现了稳定的短程同步硝化反硝化。试验还考察了碳氮比对SBBR系统短程同步硝化反硝化的影响。结果表明:在SBBR中处理城市污水实现短程同步硝化反硝化较为适合的碳氮质量比在5～8之间,亚硝酸盐氮积累率在85%以上,TN去除率可以达到80%以上。 |

| Abstract: | An independently designed sequencing biofilm batch reactor(SBBR) was used to treat urban sewage. At normal temperature(25 - 27 ℃), when the pH value was 7.2 - 7.6, the stable shortcut simultaneous nitrification denitrification could be realized as long as the aeration amount was remained at low level. The effect of carbon-nitrogen mass ratio on the shortcut simultaneous nitrification denitrification in SBBR was also investigated through the test. The results showed that: 5 - 8 was the proper carbon-nitrogen mass ratio for the realization of shortcut simultaneous nitrification denitrification in SBBR when treating urban sewage, the accumulation rate of nitrite nitrogen and the removal rate of TN could be above 85% and above 80% respectively. |
