| 中文摘要 |
| 采用弹性填料微孔曝气生物接触氧化法对受污染的水源进行修复除NH4+-N效果研究.结果表明,在正常水温20℃～27℃条件下,当污染水源CODMn7～14mg/L,NH4+-N 0.7～2.0mg/L和生物修复工艺运行参数HRT为1.4h,气:水=0.5:1,DO为7～9mg/L时,生物修复工艺可去除水源中的NH4+-N为64%～95%;在较低水温7℃～12℃条件下,当污染水源CODMn6～11mg/L,NH4+-N 1.2～8.0mg/L和生物修复工艺运行参数HRT为1.4h,气:水=0.5:1,DO为8～10mg/L时,生物修复工艺可去除水源中的NH4+-N为40%～63%.

| 英文摘要 |
| The effect of NH4+-N removal in the polluted raw water of water sources by the bioremediation action of the biocontact oxidation process with the elastic packing and micropore aerator was studied in this paper. The research results showed the bioremediation process can reach a removal ratio of 64%～95% for NH4+-N of water sources under the condition of ordinary temperature 20℃～27℃ , CODMn 7～14mg/L , NH4+-N 0.7～2.0mg/L in the water sources and the running parameters HRT 1.4h , gas and water ratio 0.5∶1 , and DO 7～9 mg/L for the bioremediation process and a removal ratio of 40%～63% for NH4+-N of water sources under the condition of low temperature 7℃～12℃ , CODMn 6～11mg/L , NH4+-N 1.2～8.0mg/L in the water sources and the running parameters HRT 1.4h , gas and water ratio 0.5∶1, and DO 8～10mg/L for the bioremediation process. |
