| 摘 要： | 生物陶粒滤池是我国目前最常见的一种地表水生物处理工艺,但目前缺乏简单实用的动力学模型来指导工程的应用设计或进行可行性论证。根据陶粒生物滤池的内部流态建立了推流式反应器模型来模拟生物陶粒滤池对有机物的去除,并采用中试规模的生物陶粒滤池处理受污染程度差异很大的两种地表水取得的实际运行数据加以验证。结果表明,对于有机物含量较低或很高的地表水,都可用一级反应的推流式反应器模型来模拟生物陶粒滤池对CODMn的去除。

| Abstract: | Bio-ceramic filter is one of the most widely used surface water treatment units in China.However,there is no simple and practical model to guide engineering design or aid the investigation of feasibility.According to the inner characteristics of fluid motion of bio-ceramic filter,plug-flow reactor model was applied to simulate organic removal of surface water.Moreover,the model was verified using the experimental data,based on the treatment of two surface waters with greatly different degree of organic pollution using pilot-scale bio-ceramic filter.The result indicates plug-flow reactor model with first-order reaction could ideally simulate the COD_ Mn removal using bio-ceramic filter. |
