中文摘要：
进行了1种新型的动态膜生物反应器（DMBR）和复合垂直流人工湿地（IVCW）的耦合工艺处理生活污水的研究。结果表明,3个阶段耦合系统对COD的去除率分别为90.34%、93.35%和93.68%,对TN去除率分别为93.84%、89.77%和85.13%,对TP去除率分别为85.36%、87.99%和90.39%,对浊度去除率分别为86.74%、97.30%和98.60%。各项出水指标均达到GB18918-2002一级A排放要求和CJ25.1-89要求,可作中水回用。DMBR单元可以有效去除COD以及浊度,同时在抗击污染负荷和水力负荷方面也有稳定表现;而IVCW作为DMBR的生物强化单元,主要是去除N、P等营养物质。
英文摘要：
A new hybrid system of DMBR-IVCW,which combines a dynamic membrane bioreactor（DMBR） unit and an integrated vertical-flow constructed wetland（IVCW） unit,was applied to treat domestic sewage.The results showed the total removal efficiencies of DMBR-IVCW system at three different operation conditions were 90.34%,93.35% and 93.68% for COD,93.84%,89.77% and 85.13% for TN,85.36%,87.99% and 90.39% for TP,and 86.74%,97.30% and 98.60% for turbidity,respectively.The effluent reaches the first level A criteria of GB 8978-1996,and can be directly used for water reclamation and reuse.It was found that the DMBR unit had good efficiency on removing COD and turbidity,together with great steady performance to buffer organic loadings and hydraulic shocks,while the IVCW unit acted more like an ecological enhanced treatment for the DMBR unit,removing N,P and other nutrients.
