Abstract

Wastewater treatment plants (WWTPs) have been recognized as one of the significant greenhouse gas (GHG) generators, due to the complex biochemical reaction and huge consumption of energy and materials. Recently, WWTPs have been built underground and they will be confronted with the challenges of mitigating GHG emissions and improving the quality of treated wastewater. Here, we focus on estimating GHG emissions to set up effective management plans for a WWTP built underground. First, we apply the process-based life cycle assessment (LCA) with an inventory database of the underground WWTP for a case study. Then, we identify significant factors affecting GHG emissions during service life using sensitivity analysis and suggest the proper tactics that could properly reduce GHG emissions from the WWTP.

地下污水处理厂温室气体排放量估算
污水处理厂由于其复杂的生化反应和巨大的能源和材料消耗,已被公认为是重要的温室气体(GHG)产生源之一。近年来,污水处理厂已建在地下,它们将面临减少温室气体排放和改善处理后废水质量的挑战。在这里,我们的重点是估算温室气体排放量,为地下污水处理厂制定有效的管理计划。首先,我们将基于过程的生命周期评价方法(LCA)应用于地下污水处理厂库存数据库的案例研究。在此基础上,通过敏感性分析找出影响污水处理厂使用寿命期间温室气体排放的重要因素,并提出相应的策略,以减少污水处理厂的温室气体排放。
