摘要

政府间气候变化专门委员会(IPCC)已将工程生物去除营养物(BNR)过程确定为大气中氧化亚氮(N2O)排放的潜在贡献者。这对污水处理公司来说是一个重要的问题,因为按质量当量计算,一氧化二氮排放的温室效应是二氧化碳的300倍。本研究量化了大规模和实验室规模的废水处理过程中N2O的排放,并表征了N2O形成的微生物途径。随着生产和排放途径的了解,减少N2O排放的操作策略似乎很有可能。本文归属于WERF研究报告丛书ISBN: 9781780408057(电子书)

Greenhouse Nitrogen Emissions from Wastewater Treatment Operations: Phase II Molecular Level Through Whole Reactor Level Characterization
Engineered biological nutrient removal (BNR) processes have been identified by the Intergovernmental Panel on Climate Change (IPCC) as potential contributors to atmospheric nitrous oxide (N2O) emissions. This is an important concern to wastewater utilities because the greenhouse impact of nitrous oxide emissions on a mass equivalent basis is 300 times that of carbon dioxide. This study quantifies N2O emissions from full-scale and lab-scale wastewater treatment processes and characterizes the microbial pathways for N2O formation. As the production and emission pathways are understood, operational strategies to minimize N2O emissions appear highly likely. This title belongs to WERF Research Report Series ISBN: 9781780408057 (eBook)
