| 中文摘要: |
| 为研究生物接触氧化工艺强化城市河道沿程污染物自净能力,在夏季丰水期选择昆明入滇大清河污水,利用弹性填料作为微生物载体,沿程取样并定期监测水质变化情况.结果表明:在出水DO为1.5 mg/L的情况下,强化河道流速在0.02 cm/s时出水效果较为理想,经强化河道处理后CODCr、TP、TN去除率可达63%～69%、43%～50%、30%～39%;通过去除悬浮物质可以去除相当一部分CODCr和少量TP、TN,可溶性CODCr、TP、TN通过载体微生物的代谢得到进一步去除. |

| Bio-contact oxidation process was used to simulate urban rivers and analyze pollutants’ degradation by strengthening their natural restoration abilities.During summer rainy period,taking wastewater of Daqinghe River as the influent,variations of water qualities were studied on different time points,with plastic bio- media as the carrier of microorganism.Experimental results show that under the velocity of 0.02 cm/s,removal rates of CODCr、TP、TN reach 63%～69%、43%～50%、30%～39%.respectively,with DO of effluent of 1.5 mg/L.Removal of suspended solids helps to decrease a great part of CODCr and a little part of TP、TN.Dissolved CODCr、TP、TN can be further degraded through metabolism of microorganism. |
