| 摘 要： | 摘要：采用移动床生物膜反应器(MBBR)处理低C/N生活污水，重点考察了填充率(PR)、水力停留时间(HRT)和溶解氧(DO)等对MBBR脱氮除磷及COD去除的影响.结果表明：在填充率为30%，控制HRT=6 h，DO=3.0±0.25 mg·L-1的条件下，经驯化的MBBR系统处理此类低C/N生活污水，COD、氨氮、TN及TP的平均去除率〖JP2〗分别为92.4%、85.8%、70.4%和40.1%，脱氮削碳效果较为理想，对于提高除磷需考虑联合其他工艺作进一步研究.

| Abstract: | Moving Bed Biofilm Reactor（MBBR） was used for treatment of domestic sewage with low C/N.The effects of packing rate（PR）,hydraulic retention time（HRT） and dissolved oxygen（DO） on COD,nitrogen and phosphorus removal have been studied.The result indicates that under the selected conditions which the PR is 30%,HRT is 6h and DO is 3.0±0.25 mg,the average removal efficiencies of COD,NH＋4-N,TN and TP are 92.4%,85.8%,70.4% and 40.1% with acclimated biofilm.There is good efficiency on removing COD and nitrogen.But to improve the efficiency of TP removal needs further study uniting other processes. |
