This paper presents a theoretical framework to model anaerobic digester structures and define performance targets using regions of attainability constructed using kinetic models and fundamental processes: mixing and biodegradation. Two digestion cases, diary manure (case 1) and diary manure + lagoon inoculum (case 2) were considered and the following main findings were obtained. Case 1 presents a linear acidogenic and exponential methanogenic uncoupling, an optimized performance target of 216.45% with optimal digester structure consisting of CSTR (continuous stirred reactor) + PFR (plug flow reactor) run in parallel with a CSTR (6 days retention time, RT) or a CSTR with bypass from feed (2days RT). Case 2 presents a linear methanogenic response, an optimized target of 142.47% with optimal digester structure consisting of a CSTR + PFR with bypass (2 & 6days RT). The framework presented in this study can be used for simultaneous optimization of performance targets and digester networks.

本文提供了一个理论框架，用于对厌氧消化池结构进行建模，并使用动力学模型和基本过程（混合和生物降解）构建的可达到性区域来定义性能目标。考虑了两个消化案例，即日记粪便（案例1）和日记粪便+泻湖接种物（案例2），并获得了以下主要发现。情况1显示了线性的产酸和指数产甲烷解耦，优化性能目标为216.45％，具有由CSTR（连续搅拌反应器）+ PFR（活塞流反应器）与CSTR并行运行（6天保留时间，RT）组成的最佳消化器结构）或CSTR，并从Feed中绕过（RT 2天）。情况2呈现线性产甲烷响应，优化目标为142。47％的最佳消化池结构由CSTR + PFR（带旁路）（RT 2和6天）组成。本研究中提出的框架可用于同时优化性能目标和摘要网络。
