摘要
借助活性污泥数学模型(ASM)能模拟污染物的微生物降解过程,是诊断和优化污水处理工艺的有效工具之一。随着人们对活性污泥法机理的深入认识,及新型污水处理工艺的开发,亟需研究者们对传统ASM进行改进。文中回顾了ASM模型的建立过程及特点,从模型结构修正、模型参数校正方法优化和多场耦合模型建立这3个方面,归纳分析了近年来国内外研究者对ASM模型改进的研究进展,并基于现有ASM在实际应用过程中的不足,对模型的改进工作提出以下几点建议:引入金属元素对污泥中微生物活性影响的动力学方程;多种方式结合改进模型参数的校正方法;耦合ASM与二次沉淀池的水力学模型,以期为ASM系列模型在活性污泥法中的推广应用提供理论参考。
Activated sludge mathematical model(ASM)can simulate microbial degradation process of pollutants by microbe,which is one of the effective tools for diagnosing and optimizing wastewater treatment process.Along with the deepening understanding of activated sludge process mechanism,and the development of new wastewater treatment technology,traditional ASM model is forced to improve by researchers.This article first reviews establishing process and characteristics of ASM model,and then reviews and discusses research progress of ASM model improvement in recent years from three aspects such as model structure modification,optimization of model parameter calibration and construction of multi-field coupling model.And based on existing deficiencies of traditional ASM in practical application process,model improvement can be started from the following aspects:introducing kinetic equations of influence of metals on microbial activity in activated sludge,combining several methods to improve model parameters calibration and coupling ASM with hydraulic model of secondary sedimentation tank,in order to provide a theoretical reference for the application of ASM models in activated sludge process.
