厌氧生物法是一种适用于处理高浓度有机废水的高效低能耗的处理工艺,厌氧消化模型是表述兼性细菌和厌氧细菌将可生物降解的有机物分解成二氧化碳、甲烷和水的过程模型。它是一个具有分解和水解、产酸、产乙酸和产甲烷等过程的复杂的结构化模型。本文主要介绍了国内外污泥厌氧消化模型的研究现状及其进展,模型包括厌氧消化1号模型(ADM1)、好氧活性污泥-厌氧消化模型(ASM1-ADM1)、单相中温-厌氧消化模型(SPMT-ADM1)、单相高温-厌氧消化模型(SPHT-ADM1)、两相-厌氧消化模型(TP-ADM1)、厌氧消化-活性污泥复合模型(ADM1-ASMs)、硫酸盐还原-厌氧消化模型(SR-ADM1)、硝酸盐还原-厌氧消化模型(NR-ADM1)、产气-厌氧消化模型(GPAE-ADM1)、沉淀池-厌氧消化模型(ST-ADM1)和抑制因子-厌氧消化模型(IK-ADM1)。对这些模型进行了综述,根据目前存在的不足对今后的研究方向提出了建议。

The anaerobic biological method is a process of low energy consumption and high efficiency to deal with high concentration organic wastewater. An anaerobic digestion model describes how the bacteria and the facultative anaerobic bacteria decompose the biodegradable organic in the sludge into carbon dioxide, methane and water under anaerobic conditions. As a structure model, it contains all procedures, including the production processes of decomposition and hydrolysis, acid, acetic acid and methane. In this paper, some sludge anaerobic digestion models are reviewed, such as the single-phase anaerobic digestion model (SP-ADM1), the Two-Phase Anaerobic Digestion Model (TP-ADM1), the combination of the Anaerobic Digestion and the Activated Sludge (ADM1-ASMs), the Sulfate Reduction of Anaerobic Digestion Model (SR-ADM1), the Nitrate Reduction of Anaerobic Digestion Expansion Model (NR-ADEM1), the Gas Production and its Expansion of the Anaerobic Digestion Model (GPAE-ADM1), the Sedimentation Tank of Anaerobic Digestion Model (ST-ADM1), and the Inhibition Kinetics of Anaerobic Digestion Model (IK-ADM1). In addition, the anaerobic digestion models are evaluated in comparison with the anaerobic digestion model 1, and some suggestions are made for future researches.
