活性污泥系统动力学模拟方法的综合分析

Comprehensive Analysis on Dynamic Simulating Method of Activated Sludge System

活性污泥法的应用现状和污水中氮磷排放标准的日益严格,使得传统数学模型已满足不了目前的要求,需要对活性污 泥系统复杂的动力学规律进行有效模拟。文章在综合分析活性污泥动态模型国内外研究现状的基础上,介绍了3种占主流地位的 模型:活性污泥数学模型、神经网络模型和混合模型。这3种模型在污水处理的设计、运行控制和工艺优化等方面各有其独到之处。

Application and the status QUO of activated sludge method and the criteria of nitrogen and phosphorus in sewage are required more strictly day by day, and the traditional mathematic model could not satisfy present requirement, so effective simulation of dynamic rule of complicated activated sludge system is necessary. In this paper, based on study the status QUO of comprehensive analysis on dynamic model of activated sludge from domestic and abroad to recommend three kinds of important models, such as: mathematic model, neural networks and hybrid model. Each model has its advantage in design, operation control and process optimization of sewage treatment.
