摘要

生物过程将进入单个或多个反应器系统的材料组分从一种转变为另一种,而不改变系统中固体、水相或气相的总物质。如果进行了可以量化生物工艺产物(输出)的物质含量的正确测量,则可以通过化学计量学从生物工艺产物确定生物工艺反应物(输入)的物质含量。基于这一质量守恒原理,提出了增强生物甲烷(AugBMP)和生物硫化物(AugBSP)电位测试程序,将BMP从独立测试转变为生物反应器,在生物反应器上进行一系列附加测试,以确定可生物降解有机物的组成。AugBSP基于生物硫酸盐还原,可以用更精确的水硫酸盐和硫化物测量取代BMP中不准确的气体测量。从理论和模型的角度评估了这两种程序的适用性。确定了以CxHyOzNaPbSc表示的进水有机物组成所需的分析测试。根据试验结果给出了计算过程的实例。由此得出结论,增强BMP (AugBMP)和BSP (AugBSP)测试程序,辅以厌氧消化动态建模,与确定可生物降解有机物组成的分析测量一样准确,并且还可以确定可生物降解有机物的水解速率和有机物的不可生物降解部分。了解厌氧消化池中有机物的这些特性对预测厌氧消化池的性能和稳定性具有重要意义。

Integration of complete elemental mass-balanced stoichiometry and aqueous-phase chemistry for bioprocess modelling of liquid and solid waste treatment systems − Part 3: Measuring the organics composition
Bioprocesses transform the components of the material entering single or multiple reactor systems from one kind to another without a change in total material exiting the system(s) in the solid, aqueous or gas phases.  Provided that the correct measurements are made that can quantify the material content of the bioprocess products (outputs), the material content of the bioprocess reactants (inputs) can be determined from the bioprocess products via stoichiometry. Based on this principle of mass conservation, the augmented biomethane (AugBMP) and biosulphide (AugBSP) potential test procedures are proposed, which change the BMP from a stand-alone test to a bio-reactor on which a range of additional tests are made to determine the composition of biodegradable organics. The AugBSP, which is based on biological sulphate reduction, can replace the inaccurate gas measurements in the BMP with the more accurate aqueous sulphate and sulphide measurements. The suitability of these two procedures is evaluated from a theoretical and modelling perspective. The analytical tests required to determine the composition of influent organics, expressed as CxHyOzNaPbSc, are identified. Examples of the calculation procedure from the test results are given. It is concluded that the augmented BMP (AugBMP) and BSP (AugBSP) test procedures, supplemented by anaerobic digestion dynamic modelling, are as accurate as the analytical measurements for determining the composition of biodegradable organics, and also allow the hydrolysis rate of the biodegradable organics and the unbiodegradable fraction of the organics to be determined. Knowing these characteristics of organics fed to anaerobic digesters is important to predict the anaerobic digester performance and stability.
