| 摘 要： | 通过中试考察了曝气生态浮床/可渗滤反应墙(EAFB-PRB)组合工艺对重污染河水的净化效果.结果表明:组合工艺对COD、TN、NH_4~+-N和TP都有较好的去除效果,平均去除率分别为79.5%、27.9%、36.8%和87.0%;经处理后,水体的平均DO浓度由0.09 mg/L提高到1.7mg/L;对TSS的平均去除率达95.4%,出水清澈透明,感官效果好.可见,该组合工艺是改善重污染河水水质的有效方法.

| Abstract: | The purification effect of heavy polluted river water by combined process of ecological aeration floating bed and permeable reactive barrier (EAFB-PRB) was investigated in a pilot study. The results show that the combined process has high removal efficiencies of COD, TN, NH_4~+ -N and TP, with the average removal rates of 79.5%, 27.9%, 36.8% and 87.0%, respectively. The concentration of DO increases from 0. 09 mg/L to 1.7 mg/L. Moreover, the average removal rate of total suspended solids (TSS) can reach 95.4%. The outflow is clear and transparent. It is obvious that the combined process is an effective method for improving heavy polluted river water quality. |
