摘 要: | 为研究在本源微生物菌剂治理污染河流的过程中DO、COD和氨氮随时间的变化规律,以河流自净原理为理论基础,从反映微生物增殖的Monod模型、着重于生物处理过程基本原理的活性污泥1号模型(ASM1)和水质模型Streeter-Phelps三方面对微生物在污染水体中的降解活动进行数学描述,利用耦合模型模拟甘坑河治理过程中DO、COD和氨氮的浓度变化。结果表明,DO、COD和氨氮的模拟值与实测值较吻合,耦合模型对本源微生物菌剂治理污染河流的过程的模拟较为理想。

Abstract: | On the basis of river self-purification theory, this paper described the process of microbial degeneration in polluted water using Streeter-Phelps model, ASM1 model and Monod model and developed a model coupling these three models and simulated the change of DO,COD and NH3-N concentration in the process of Gankeng River treatment by origin-microorganism bacteria. The results show that the simulation value is consistent with the actual measured value and the simulation results of river treatment by origin-microorganism bacteria is ideal. |
