| 摘 要： | 在常温条件下进行兼性生化处理生活污水试验,研究COD去除率与HRT、MLSS、进水有机物浓度和混合液水温的关系。在试验中最佳的水平搭配为MLSS=5500mg/L,进水有机物浓度=180mg/L,HRT=8h和混合液水温=20℃,与回归分析所得出MLSS=5881mg/L,进水有机物浓度=192.7mg/L,HRT=8.9063h和混合液水温=21.3790℃的最佳工艺条件相吻合。最后通过等高线分析得出常温下生活污水兼性生化的适宜范围。

| Abstract: | Facultative biochemical technology was used for sewage treatment through a lab-scale experiment under room temperature condition to discuss the relationship of removal efficiency of COD with HRT, MLSS, influent organic density and mixed liquor temperature. Results showed that the best conditions obtained in the lab-scale experiment are identical to that obtained by regression. The suitable conditions of facultative biochemical technology for sewage treatment is obtained through response curved surface analysis under room temperature condition. |
