چکیده
Background: Wastewater treatment plants are important sources of emissions of greenhouse gases (GHSs) such as carbon dioxide and methane in the atmosphere. Also, energy consumption in the wastewater treatment process causes indirect carbon dioxide emissions. Methods: One hundred thirty-three operating wastewater treatment plants in Iran treat municipal wastewater. The carbon dioxide and methane emissions from the wastewater treatment plants for the year ۲۰۲۲ were estimated by establishing a calculation model according to the methods recommended by the Intergovernmental Panel on Climate Change for National Greenhouse Gas Inventories (۲۰۰۶) and United States Environmental Protection Agency (USEPA) guidelines. Results: Based on the Intergovernmental Panel on Climate Change guideline, the total methane emission was ۱۵۸.۶۳ tons. Based on the USEPA guideline, the total emissions of methane and carbon dioxide were ۴۷.۶۱ and ۳۵۱.۴۷ tons, respectively. This amount is ۳.۲% of all the methane and carbon dioxide emissions of Iran. Isfahan and Tehran provinces have the highest emissions rates of methane at ۳۱.۸۵ and ۲۲.۹۱ tons, respectively. While South Khorasan and Kerman provinces have the lowest methane emissions rates of ۰.۴۶ and ۰.۶۷ tons, respectively. Conclusion: The results will provide a scientific basis and effective strategies for policymakers to reduce the methane and carbon dioxide emissions from the wastewater treatment plants of Iran.کلیدواژه ها

COI مخفف عبارت CIVILICA Object Identifier به معنی شناسه سیویلیکا برای اسناد است. COI کدی است که مطابق محل انتشار، به مقالات کنفرانسها و ژورنالهای داخل کشور به هنگام نمایه سازی بر روی پایگاه استنادی سیویلیکا اختصاص می یابد.
کد COI به مفهوم کد ملی اسناد نمایه شده در سیویلیکا است و کدی یکتا و ثابت است و به همین دلیل همواره قابلیت استناد و پیگیری دارد.
