项目摘要

Primary sludge fermentation has recently been implemented in many centralized wastewater treatment plants worldwide, which provides a breakdown of unsaturated fats into volatile fatty acids (VFAs). The VFAs-rich sludge fermentation liquor can be utilized on-site as an exogenous carbon source for the biological nutrient removal (BNR) processes. The proposed collaborative research focuses on developing efficient operational strategies for sludge fermentation that suit Canadian climate conditions. Due to the more stringent regulations for nutrients (nitrogen and phosphorus) removal, many wastewater treatment plants across Canada have already adopted or are considering implementing primary sludge fermentation to produce readily biodegradable carbon sources for the effective operation of the BNR process. The residual solids from the fermentation process are usually mixed with waste activated sludge and processed in an anaerobic digestion (AD) facility. Thus, in addition to BNR, the performance of sludge fermentation operation would also influence the AD process. In general, various process parameters of the fermentation process can influence VFAs yields and spectrums, including temperature, sludge characteristics, residence times, pH, etc., ultimately influencing the operation of BNR and AD. Thus, holistic process optimization is critically needed to effectively deploy sludge fermentation in wastewater treatment plants. Consequently, this proposed project aims to develop fundamental knowledge and engineering approaches toward optimizing the primary sludge fermentation process in wastewater treatment plants considering the diverse climate conditions in Canada between the summer and winter months. In this proposed project, the research team will undertake detailed and systematic bench-scale studies, machine learning and process simulation activities, and pilot validation of the lab and modeling results. In addition to improving the existing operation of the partner organization's full-scale facility, the experience and knowledge generated in this project will enhance operational approaches to sludge fermentation in other wastewater treatment plants across Canada.
世界各地的许多集中式污水处理厂最近实施了一次污泥发酵,将不饱和脂肪分解为挥发性脂肪酸(VFA)。富含VFAS的污泥发酵液可作为外源碳源用于生物脱氮(BNR)工艺。拟议的合作研究重点是开发适合加拿大气候条件的高效污泥发酵操作策略。由于对营养物(氮和磷)的去除规定更加严格,加拿大各地的许多污水处理厂已经采用或正在考虑实施初级污泥发酵,以产生易于生物降解的碳源,以实现BNR工艺的有效运行。发酵过程中的残余固体通常与废弃的活性污泥混合,并在厌氧消化(AD)设施中进行处理。因此,除BNR外,污泥发酵运行的好坏也会对AD工艺产生影响。总体而言,发酵过程的各种工艺参数都会影响VFA的产量和光谱,包括温度、污泥特性、停留时间、pH等,最终影响BNR和AD的运行。因此,为了有效地在污水处理厂中部署污泥发酵,迫切需要进行整体工艺优化。因此,这个拟议的项目旨在开发基础知识和工程方法,以优化污水处理厂的初级污泥发酵过程,考虑到加拿大夏季和冬季之间不同的气候条件。在这个拟议的项目中,研究小组将进行详细和系统的实验室规模研究、机器学习和过程模拟活动,以及实验室和建模结果的试点验证。除了改进合作伙伴组织全面设施的现有运营外,该项目产生的经验和知识还将加强加拿大其他废水处理厂的污泥发酵操作方法。
