Optimization of biofilm and hydrodynamics for Anaerobic Biocord Bioreactors (AnBioCord)

厌氧消化是有机废物的首选处理工艺，因为其营养需求低，生物质产量低，沼气（CH 4）的生产。厌氧消化工艺已被广泛应用于各种复杂的原料，包括城市污水污泥，化工和农业工业废水。然而，目前常规的厌氧消化工艺需要长达40天的水力停留时间（HRT）来实现有机废物的必要稳定，这转化为大的足迹。 另一种方法是设计和开发一种可持续的厌氧生物膜消化系统，该系统不仅能够在高悬浮固体含量下集成功能，即生物降解、生物质-液体分离和生物质保留，同时降低能量需求，而且还可以容易地应用于改造现有的传统技术。与传统系统相比，AnBioCord具有许多优势，包括占地面积小，水力停留时间（HRT）与固体停留时间（SRT）分离，以及高生物质-液体分离。拟议的系统将用于改造和开发一种经济，稳健和有效的工艺，以提高生物甲烷形式的生物能源的生产，在高强度有机城市和工业流的处理过程中。这项研究的目的，在合作与主教水技术公司。(BWT)开发了一种新型厌氧生物膜BioCord消化系统（AnBioCord）。这将使用实验室规模的AnBioCord系统来实现，以了解生物膜过程的流体动力学，并优化环境参数（即营养成分和浓度、pH值和离子相互作用的强度）对生物膜的影响，以提高生物反应器效率，并在BioCord材料的影响和生物膜性能之间建立基本的科学关系。

Anaerobic digestion is the preferred treatment process for organic wastes due to its low nutrient requirements, low biomass yield, and biogas (CH4) production. Anaerobic digestion processes have been widely applied to various complex feedstocks including municipal wastewater sludge, chemical, and agricultural industry wastewater. However, current conventional anaerobic digestion processes require a hydraulic retention time (HRT) of up to 40 days to achieve the necessary stabilization of organic wastes, which translates to a large footprint. An alternative approach is to design and develop a sustainable anaerobic biofilm digestion system that is not only capable of integrating functions i.e. biodegradation, biomass-liquid separation, and biomass retention at high suspended solids content while reducing energy demand but also can be easily applied to retrofit existing conventional technologies. The AnBioCord offers numerous advantages over conventional systems including low footprint, decoupling of hydraulic retention time (HRT) from solids retention time (SRT), and high biomass-liquid separation. The proposed system will be used to retrofit and develop an economical, robust and efficient process to enhance the production of bioenergy in the form of biomethane during the treatment of high strength organic municipal and industrial streams. The objective of this research, in collaboration with Bishop Water Technologies Inc. (BWT), is to develop a new anaerobic biofilm BioCord digestion system (AnBioCord). This will be achieved using a lab-scale AnBioCord system to understanding the hydrodynamic of biofilm process and optimize the effect of environmental parameters (i.e. nutrient composition and concentration, pH, and the strength of ionic interactions) on biofilm to increase the bioreactor efficiency and develop a fundamental scientific relationship between the effect of BioCord materials and biofilm performance.
