摘要
从活性污泥法污水处理过程的复杂性和丰富的动力学行为出发,结合活性污泥去污机理及其生长规律,建立了活性污泥吸附和稳定过程的细胞自动机模型,并利用实际参数进行仿真实验。结果表明,该细胞自动机模型能复现活性污泥的吸附和稳定过程,反映BOD(生化需氧量)的去除情况和活性污泥的生长状况,实现活性污泥系统曝气池内污水处理过程的动态可视化模拟,展现了细胞自动机模拟污水处理过程的优势,并为类似复杂系统建模提供基本思路。
Considering the complexity and abundant kinetics behaviors in activated sludge wastewater treatment, a cellular automata model （CA） for adsorption and stabilization processes in activated sludge was established based on the biological mechanism and the growth law of activated sludge, and the simulation experiment was made using practical parameters. The results indicate the CA model well reappears the complex adsorption and stabilization processes, and well describes the removal rate of BOD and the growth of activated sludge. The CA model simulates activated sludge wastewater treatment in the bioreactor dynamically and visually, and exhibits advantages of modeling wastewater treatment by CA, while offering basic means for similar complex systems.
