Emissions from municipal sewers are usually omitted from hazardous air pollutant (HAP) emission inventories. This omission may result from a lack of appreciation for the potential emission impact and/or from inadequate emission estimation procedures. This paper presents an analysis and comparison of the models available to estimate volatile organic HAP (VOHAP) emissions from sewers. Comparisons were made between the different theoretical foundations of the models, as well as between the emissions predicted by the models for a single sewer component. Sewer gas concentrations predicted by the models were also compared to measured sewer gas concentrations reported in the literature. Two of the models were compared in their ability to estimate sewer VOHAP emissions for a large U. S. city using National Pollution Discharge Effluent System data for the influent wastewater to the city's municipal wastewater treatment facilities. This estimate showed that, regardless of the model used, sewer emissions are a potentially significant source of VOHAP emissions in the urban environment. The choice of model, however, is thought to be less critical to sewer emission estimates than the source of sewer wastewater VOHAP concentration data.
城市下水道排放通常被排除在有害空气污染物(HAP)排放清单之外。这种遗漏可能是由于对潜在排放影响认识不足和/或排放估算程序不完善造成的。本文对可用于估算下水道挥发性有机有害空气污染物(VOHAP)排放的模型进行了分析和比较。比较了模型不同的理论基础,以及单个下水道组件模型预测的排放量。模型预测的下水道气体浓度也与文献中报道的实测下水道气体浓度进行了比较。利用美国一个大城市市政污水处理设施进水废水的国家污染排放消除系统数据,比较了其中两个模型估算该城市下水道VOHAP排放的能力。该估算表明,无论使用何种模型,下水道排放都是城市环境中VOHAP排放的一个潜在重要来源。然而,人们认为,对于下水道排放估算而言,模型的选择不如下水道废水VOHAP浓度数据的来源关键。
