摘要
活性污泥法水处理过程是一个复杂的生化反应过程,伴随有物理化学反应、生化反应、相变过程及物质与能量的转化和传递过程。通过对微生物动力学方程的讨论,进而建立动力学模型,比较了Monod方程和Contois方程分别来模拟有机碳在曝气条件下的生化去除过程。模型主要预测底物浓度、溶解氧、微生物增长等引起的系统响应,为污水处理厂的运行提供指导。
Activated sludge method is a complicated biochemical process in water treaunent, with physical and biochemical reaction, phase change and the transformation and transmission process of matter and energy. After the discussion on the kinetic tquation, the dynamics model is set up and Monod kinetics equation and Contois equation are compared to simulate the biochemical removal process of organocarbon at the condition of airing. The model mainly fotecasts the response of the system, resulted from some factors, such as nutrient concentration, dissolved oxygen and microbion growth and the results will instruct the run of sewage disposal plant.
