Based on activated sludge model No. 2 (ASM2), the anaerobic/aerobic kinetic model of phosphorus-accumulating organisms (PAO) was established with mixed short-chain fatty acids (SCFAs) as the base substance in enhanced biological phosphorus removal process. The characteristic of the PAO model was that the anaerobic metabolism rates of glycogen degradation, poly-beta-hydroxyalkanoates synthesis and polyphosphate hydrolysis were expressed by SCFAs uptake equation, and the effects of anaerobic maintenance on kinetics and stoichiometry were considered. The PAO kinetic model was composed of 3 soluble components, 4 particulate components and a pH parameter, which constituted the matrix of stoichiometric coefficients. On the basis of PAO model, the GAO kinetic model was established, which included 7 processes, and phosphorus content influenced the aerobic metabolism only.
基于活性污泥2号模型（ASM2），以混合短链脂肪酸（SCFAs）为基础物质，建立了强化生物除磷过程中聚磷菌（PAO）的厌氧/好氧动力学模型。PAO模型的特点是，糖原降解、聚β-羟基烷酸酯合成和聚磷酸盐水解的厌氧代谢速率由SCFAs吸收方程表示，并考虑了厌氧维持对动力学和化学计量的影响。PAO动力学模型由3个可溶性组分、4个颗粒性组分和1个pH参数组成，它们构成了化学计量系数矩阵。在PAO模型的基础上，建立了GAO动力学模型，该模型包括7个过程，且磷含量仅影响好氧代谢。
