| 中文摘要: |
| 考察了不同填料填充率下，组合式A2/O对某污染河水的净化效果.结果表明,好氧区填充率为20％和60％时，在进水水质COD：51.00～67.33 mg/L，NH+4-N：6.51～9.89 mg/L，TN：9.39～14.09 mg/L，TP：0.79～1.30 mg/L情况下，好氧区填料填充率60％的装置的去除效果好于填料填充率20％.考虑该工艺对污水较好的净化效果，该工艺适宜好氧区填料填充率为60％，此时主要污染指标平均去除率分别为COD：56.23％，NH+4-N：54.57％，TN：35.73％，TP：27.04％. |

| Purifying effect of the modular A2/O on the polluted river water at the different filler filling rates is investigated.The results show that while aerobic zone filling rate are 20% and 60%,the removal effect of the device with aerobic zone filling rate 60% is better than the device with aerobic zone filling rate 20% in the conditions such as COD:51.00～67.33 mg/L,NH+4-N:6.51～9.89 mg/L,TN:9.39～14.09 mg/L,TP:0.79～1.30 mg/L.This process is suitable for the aerobic zone filling rate 60% while the effect of this process on the polluted water is considered.And the average removal rates of the major pollution are COD:56.23%,NH+4-N:54.57%,TN:35.73%,TP:27.04%,respectively at this time. |
