| 中文摘要 |
| 从反应器理论、生物膜动力学及水力学的角度对内循环式三相生物流化床反应器的流态、生物膜降解有机物及启动挂膜特性进行了分析,一认为在内循环三相流化床中D/ud=const,对于一般城市污水处理系统求出了效率因子,建立了内循环速度与反应器尺寸的关系,同时提出了可能进一步提高反应器处理效率的优化途径。 |
| 英文摘要 |
| An analysis on the flow pattern, the organic matter degradation by biofilm, and the biofilm forming in an internal circulating three-phase biofluidised bed was conducted, based on the reactor theory, biofilm kinetics and hydrodynamics, It was found that D/ud was constant in the reactorand the efficiency factor was calculated for a general municipal wastewater treatment system and the relationship between circulating velocity and reactor size was estabilished.Some possible optimization ways to increase the reactor efficiency was also suggested. |
