To investigate the overall effects of carbon source types on wastewater treatment plant (WWTP) performance, this study compared the impacts of three external carbon sources—a composite carbon source, sodium acetate and glucose—on the overall operational process. The results demonstrated that different carbon sources led to variations in the metabolic performance of heterotrophic microorganisms. Under the influence of the three carbon sources, the heterotrophic yield coefficients YH were 0.703 (composite carbon source), 0.676 (sodium acetate), and 0.889 (glucose), respectively. The heterotrophic decay coefficients bH were 0.405, 0.433 and 0.775d-1, while the maximum heterotrophic growth rates μmH were 2.146, 3.071 and 6.078d-1 respectively. Using GPS-X software, a model of the target WWTP was constructed and calibrated. The kinetic parameters under each carbon source were incorporated into the model for simulation. The results indicated that changes in kinetic parameters directly affected the treatment efficiency, energy consumption, sludge production, and greenhouse gas (GHG) emissions of the WWTP. In terms of total nitrogen removal efficiency, the composite carbon source and sodium acetate exhibited more significant advantages, albeit with increased energy consumption and GHG emissions. In contrast, while glucose was more energy-efficient and reduced carbon emissions, it resulted in lower nitrogen removal efficiency and potentially higher sludge production. After considering market pricing, the composite carbon source was found to be a more competitive option for denitrification.

为探究碳源种类对污水处理厂运行的整体影响,对比了某复合碳源,乙酸钠以及葡萄糖3种外加碳源对污水处理厂整体运行过程的影响,结果表明,碳源种类的不同造成了异养微生物代谢性能发生变化,三种碳源影响下的异养菌产率YH为0.703(复合碳源),0.676(乙酸钠)与0.889(葡萄糖);异养菌衰减系数bH为0.405,0.433与0.775d-1;异养菌最大生长比μmH为2.146,3.071与6.078d-1.应用GPS-X软件对目标污水厂进行了模型构建与校正,并将各碳源影响下的动力学参数代入模型进行模拟,结果显示:动力学参数的变化直接影响了污水处理厂的处理效率,电能消耗,污泥产量及温室气体排放.在TN去除率方面,复合碳源,乙酸钠有着更为显著的优势,但伴随着耗能与温室气体排放的增加;而葡萄糖虽更加节能降碳,但除氮效率较低,且可能导致污泥量增加.在综合了市场价格考量后,认为复合碳源作为反硝化碳源更具竞争力.

为探究碳源种类对污水处理厂运行的整体影响,对比了某复合碳源,乙酸钠以及葡萄糖3种外加碳源对污水处理厂整体运行过程的影响,结果表明,碳源种类的不同造成了异养微生物代谢性能发生变化,三种碳源影响下的异养菌产率YH为0.703(复合碳源),0.676(乙酸钠)与0.889(葡萄糖);异养菌衰减系数bH为0.405,0.433与0.775d-1;异养菌最大生长比μmH为2.146,3.071与6.078d-1.应用GPS-X软件对目标污水厂进行了模型构建与校正,并将各碳源影响下的动力学参数代入模型进行模拟,结果显示:动力学参数的变化直接影响了污水处理厂的处理效率,电能消耗,污泥产量及温室气体排放.在TN去除率方面,复合碳源,乙酸钠有着更为显著的优势,但伴随着耗能与温室气体排放的增加;而葡萄糖虽更加节能降碳,但除氮效率较低,且可能导致污泥量增加.在综合了市场价格考量后,认为复合碳源作为反硝化碳源更具竞争力.

To investigate the overall effects of carbon source types on wastewater treatment plant (WWTP) performance, this study compared the impacts of three external carbon sources—a composite carbon source, sodium acetate and glucose—on the overall operational process. The results demonstrated that different carbon sources led to variations in the metabolic performance of heterotrophic microorganisms. Under the influence of the three carbon sources, the heterotrophic yield coefficients YH were 0.703 (composite carbon source), 0.676 (sodium acetate), and 0.889 (glucose), respectively. The heterotrophic decay coefficients bH were 0.405, 0.433 and 0.775d-1, while the maximum heterotrophic growth rates μmH were 2.146, 3.071 and 6.078d-1 respectively. Using GPS-X software, a model of the target WWTP was constructed and calibrated. The kinetic parameters under each carbon source were incorporated into the model for simulation. The results indicated that changes in kinetic parameters directly affected the treatment efficiency, energy consumption, sludge production, and greenhouse gas (GHG) emissions of the WWTP. In terms of total nitrogen removal efficiency, the composite carbon source and sodium acetate exhibited more significant advantages, albeit with increased energy consumption and GHG emissions. In contrast, while glucose was more energy-efficient and reduced carbon emissions, it resulted in lower nitrogen removal efficiency and potentially higher sludge production. After considering market pricing, the composite carbon source was found to be a more competitive option for denitrification.
