| 摘 要： | 以二相颗粒活性炭生物流化床(FBBR)为反应器,对以有机物和NH4+N为主要污染物的某大城市内河原水进行了预处理试验研究,在HRT12～18min,气水比20～25∶1,回流比3～4∶1的条件下FBBR对CODCr、NH4+N、NO2-N、浊度、色度的去除率分别为4132%、100%、97%～100%、6880%、30%～50%,而且对NH4+N和NO2+N有较强的抗冲击负荷能力。

| Abstract: | A two phase granular activated carbon fluidized bed bioreactor (FBBR) was tested in this study to treat the raw water with COD Cr and NH + 4 N as its main pollutants from a river in the urban area of a big city. Under such operating parameters as HRT=12～18min,aeration rate=2～2.5∶1,back flow ratio=3～4∶1,it could remove 41.32% of COD Cr ,100% of NH + 4 N,97～100% of NO - 2 N,68.8% of turbidity,30～50% of color in average, respectively.This processalso had a high resistance against drastic concentration changes in NH + 4 N and NO - 2 N. |
