Model for Sequencing Batch Reactor of Activated Sludge Processes Based on Cellular Automata

根据活性污泥法的去污机理和细胞自动机的特征,结合序批式反应池的特点,建立了序批式反应池的细胞自动机模型,并利用实际参数进行仿真实验。结果表明该模型能够描述出污水中有机物被吸附再被降解的过程和微生物的生长、繁殖及死亡等过程,从而描绘了有机物的去除过程和活性污泥的生长过程曲线,实现了污水处理过程的可视化,为复杂系统控制奠定基础。最后,分析了该模型的应用情况。

According to biological mechanism of activated sludge processes and the characteristics of cellular automata,a cellular automata model for a sequencing batch reactor was constructed.Simulations were made with practical parameters.The results indicate that the model replicates adsorption and biodegradation of organic matter,and simulates the growth,reproduction and death of microorganism.Therefore,it well describes the removal of organic matter and the growth of activated sludge.The model simulates activated sludge processes visually during reaction time,as a basis for the control.At last,the applications of this model were analyzed.
