| 摘 要： | 研究了循环流软性填料生物膜反应器的同时硝化反硝化。实验结果表明,反应器中确实存在着同时硝化反硝化现象。考察了碳氮比(C/N)和溶解氧(DO)对同时硝化反硝化的影响。在进水COD和NH4+—N浓度为500mg/L、15mg/L时,出水COD、NH4+—N和TN浓度<50mg/L、3.0mg/L、4.5mg/L,COD去除率、硝化率和反硝化率分别达到90%、80%和70%。

| Abstract: | SND(simultaneous nitrification and denitrification) is investigated using a circulation-flow fibrour-carriers biofilm reactor.The study result shows that SND are successfully carried out in the reactor.The effects of C/N rations and DO concentrations on SND are discussed.When the influent COD concentration is 500mg/L and NH_4~+-N concentration is 15mg/L,the concentrations of COD,NH_4~+-N and TN in the outlet are smaller than 50 mg/L,3mg/L and 4.5 mg/L,and COD removal rate,nitrification efficiency and denitrification efficiency are 90%,80% and 70% respectively. |
