摘　　要：以污染物对流扩散理论为基础,在分析下水道系统水环境中各种物理、化学和生物现象的基础上,结合活性污泥数学模型(ASM)的相关理论,建立了下水道系统的微生物和水质转化数学模型,该模型考虑了多个水质变量间的耦合计算及其相互转化和迁移过程。应用实验室实测资料对模型进行验证分析,计算结果和实测值吻合较好,表明该模型可为下水道系统的设计、水质评估等提供指导,也可为污水处理厂等提供前期水质参考。Based on one-dimensional advection-diffusion equation, as well as the analysis of physical and biochemical process in combined sewerage systems and activated sludge model (ASM) theory, the integrated wastewater quality model was developed for combined sewerage systems, in which some contamination variables and transformations and transplant of contamination variables were considered. Data from the laboratory were used to validate the model, and simulated results were in well accordance with corresponding me...
