This study explored the feasibility and estimated the environmental impacts of two novel wastewater treatment configurations. Both include combined bioflocculation and anaerobic digestion but apply different nutrient removal technologies, i.e. partial nitritation/Anammox or microalgae treatment. The feasibility of such configurations was investigated for 16 locations worldwide with respect to environmental impacts, such as net energy yield, nutrient recovery and effluent quality, CO emission, and area requirements. The results quantitatively support the applicability of partial nitritation/Anammox in tropical regions and some locations in temperate regions, whereas microalgae treatment is only applicable the whole year round in tropical regions that are close to the equator line. Microalgae treatment has an advantage over the configuration with partial nitritation/Anammox with respect to aeration energy and nutrient recovery, but not with area requirements. Differential sensitivity analysis points out the dominant influence of microalgal biomass yield and wastewater nutrient concentrations on area requirements and effluent quality. This study provides initial selection criteria for worldwide feasibility and corresponding environmental impacts of these novel municipal wastewater treatment plant configurations.
本研究探索了两种新型废水处理配置的可行性，并估算了它们的环境影响。这两种配置都包括组合生物絮凝和厌氧消化，但采用了不同的营养物质去除技术，即部分亚硝化/厌氧氨氧化或微藻处理。针对全球 16 个地点，从环境影响（如净能量产量、营养物回收和出水质量、CO 排放以及面积需求）方面，评估了这些配置的可行性。研究结果从定量上支持了部分亚硝化/厌氧氨氧化在热带地区和一些温带地区的适用性，而微藻处理仅适用于接近赤道线的热带地区全年。与部分亚硝化/厌氧氨氧化配置相比，微藻处理在曝气能耗和营养物回收方面具有优势，但在面积需求方面没有优势。差异敏感性分析指出，微藻生物量产量和废水营养物浓度对面积需求和出水质量的主导影响。本研究为这些新型城市污水处理厂配置在全球范围内的可行性及其相应的环境影响提供了初步的选择标准。
