| 摘 要： | 利用高速泳动床反应器作为预处理装置处理村镇微污染水体,出水进入组合人工湿地。结果表明,实验阶段高速泳动床在HRT为1.2 h时,尽管泳动床进水各污染物浓度较低,但反应器对COD、TN和TP仍具有较明显（P〈0.05）的去除效果,平均去除率分别为11.3%、14.6%和25.8%。高速泳动床反应器对氨氮去除效果尤为明显,去除率达到46.9%。此外,高速泳动床反应器内硝化作用较强,出水中硝态氮含量平均增加率为45.5%,弥补了后续人工湿地硝化作用不强、除氨氮效果不佳的缺点。

| Abstract: | Biofringe bed was applied to pretreat eutrophic micro-polluted water in village before flow into a constructed wetland. The results indicated that during experimental period, biofringe bed had significant （P 〈 0.05） purification effects. The average removal rates of COD, TN and TP were 11.3% , 14.6% , and 25.8% , respectively. Especially, the biofringe bed showed excellent transformation efficiency of NH3-N with the removal rate of 46. 9%. In the BF reactor, nitrification process was relatively powerful, and NO3^- -N in outlet increased by 45.5% on average, as compared to that in input, which can compensate for weakness of low nitrification and NH3-N removal rate in constructed wetlands. |
