Abstract

Abstract

In the context of global climate change, urban domestic wastewater treatment plants, as a crucial component of urban water supply and drainage systems, are complex sources of greenhouse gas emissions. This study, based on the emission factor method, conducted a carbon emission accounting for four domestic wastewater treatment plants using different processes in a provincial capital city in southeastern China. Those processes include the Carrousel oxidation ditch (OD), anaerobic-anoxic-oxic (A²/O), anaerobic-anoxic-oxic combined with membrane bioreactor (A²/O+MBR), and cyclic activated sludge system (CASS). The results indicated significant differences in the total and structural carbon emissions among the four treatment plants. The A²/O+MBR process exhibits the highest carbon emission intensity, averaging 0.403 kg CO₂-eq/m³, due to its high energy consumption and chemical usage. The CASS process, with its cyclic operation mode, shows a significant proportion of N₂O emissions but has obvious advantages in terms of electricity and chemical consumption. The OD and A²/O process operate stably with relatively lower fluctuations in carbon emission intensity. The study also found that treatment water volume and influent TN concentration are key factors influencing carbon emission intensity, with the A²/O+MBR process demonstrating a significant scale effect. Based on the analysis, this paper proposed carbon reduction strategies for wastewater treatment plants in southeastern China, including optimizing process selection, addressing key influencing factors, proactively responding to low water quality issues, and establishing localized emission factors. Implementing these strategies can effectively reduce carbon emissions in the wastewater treatment process and promote the development of low-carbon and efficient wastewater treatment.
