摘要: 对污水处理中的温室气体产生机理进行研究。采用生态环境部推荐的方法，对排放因子进行符合工程实际的调整，以甲醇工业污水处理厂的温室气体排放为例，探究不同N2O排放因子的影响，以及结果差异性。结果表明：污水中污染物去除与温室气体(GHG)有关联机制，COD的削减对应CH4，TN的削减会产生N2O；排放因子对结果影响显著，选择合适排放因子至关重要；从温室气体排放总量上来看，直接排放的总量最大，其次是能耗产生的间接排放。
Abstract: The mechanism of greenhouse gas generation in wastewater treatment was investigated. Using the method recommended by the Ministry of Ecology and Environment, the emission factors were adjusted to meet the engineering reality, and the effect of different N2O emission factors and the variability of the results were investigated with the example of GHG emission from A/O wastewater treatment. The results show that: there is a correlation mechanism between pollutant removal and GHG in wastewater, removal of COD corresponds to CH4, and removal of TN generates N2O; emission factors have a significant impact on the results, and the selection of appropriate emission factors is crucial; in terms of total GHG emissions, direct emissions are the largest, followed by indirect emissions from energy consumption.
