摘要：
Nitrous oxide (N2O) emissions from primary and secondary wastewater treatment processes were measured during spring and summer 1993 in Durham, NH. The most significant emissions occurred during secondary aeration. Dissolved N2O generated as a result of denitrification during primary settling was stripped from the liquid during mechanical aeration. Emission factors derived from our field measurements included per capita emissions of 3.2 g of N2O person(-1) yr(-1) and flow based emissions of 1.6 x 10(-6) of N2O (L of wastewater)(-1).
