摘　　要：从本质上说,污水生物处理的过程就是微生物能量代谢的过程,从能量的角度出发,在质量守恒与能量守恒的基础上建立了能量代谢方程,同时通过模型试验求解出其中的参数。该方程从微观的角度解释了活性污泥系统中泥龄选择的理由,可运用该方程优化低负荷下活性污泥工艺的系统泥龄,从而优化活性污泥系统的能量配置,达到节能降耗的目的。Substantially, the process of biological treatment for wastewater is the process of bacterial energy metabolism. In this paper, from the viewpoint of energy and based on the conservation of mass and energy, an energy metabolism equation is constructed. Through the experimentation, the parameters in equation are measured. Through this equation the reason for SRT choice of activated sludge system is explained from the viewpoint of microcosmic. This equation is adaptable to optimizing the SRT of activated sludge system in the condition of low-organic load thereby to optimizing the energy distribution of activated sludge system for energy saving
