低劣生物质厌氧消化可以减少温室气体的排放并且生产生物甲烷作为能源。介绍了关于厌氧消化过程、底物的相关理论，还对目前主要用于厌氧产甲烷过程研究的数学模型以及碳氮磷转化的模拟研究进行了综述。其中，一级动力学模型是最为简单的数学模型，其可以通过简单的计算得到整个过程中甲烷产量随着时间的变化曲线，但是只限于较准确模拟甲烷产率的ADM1模型相对发展最为全面、应用最为广泛，且能够针对具体要研究的对象进行模型的修改。同时总结了较为常见的底物厌氧产甲烷研究模型、研究对象及结果、已有碳/氮/磷转化模拟研究及相关研究，并对开展针对厌氧产甲烷过程中碳氮磷转化的模拟研究进行了展望。

Anaerobic digestion of low-grade biomass has attracted increasing interest in reducing greenhouse gas emission and facilitating sustainable development of energy supply. The theory of anaerobic digestion biogas generation and feedstocks are presented in this paper. It provides a review on mathematical model of and simulation research on the conversion of C, N, P in the process of anaerobic digestion. First order kinetic model is the simplest mathematical model which can simulate the dynamics of methane production. The advanced mathematical ADM1 is most popular, and simulates the conversion of C, N, P in anaerobic digestion. The model, simulation subjects and results of anaerobic digestion biogas generation of common substrates are given. Methane yield is the main subject of simulation investigation which is studied inalmost all simulation researches on anaerobic digestion biogas generation, and some research reports the variation of volatile solid, volatile fatty acid, COD, CH4, CO2 and inorganic carbonate in the process of anaerobic digestion through mathematical modeling, with which the conversion of C can be determined. Simulation researches on the conversion of N include variations of ammonia nitrogen, inorganic nitrogen and total nitrogen. Simulation research on the conversion of P from sludge digestion is also presented. The challenges and future research trends of the conversion of C, N, P in the process of anaerobic digestion are forecasted.
