For decades, there has been a strong interest in mitigating greenhouse gas (GHG) emissions from wastewater treatment plants (WWTPs). Numerous models were developed to measure the emissions and propose the quantification. Existing studies looked at the relationship between GHG emissions and operational cost (OCI), which is one of the most important indicators for decision-makers. Other parameters that can influence the control strategies include the effluent quality (EQI) and total environmental impacts. Plant-wide models are reliable methods to examine the OCI, EQI and GHG emissions while Life cycle assessment (LCA) works to assess the potential environmental impacts. A combined LCA and plant-wide model proved to be a valuable tool evaluating and comparing strategies for the best performance of WWTPs. For this study involving a WWTP, the benchmark model is used while LCA is the decision tool to find the most suitable treatment strategy. LCA adds extra criteria that complement the existing criteria provided by such models. Complementing the cost/performance criteria is proposed for plant-wide models, including environmental evaluation, based on LCA, which provides an overall better assessment of WWTPs. It can capture both the dynamic effects and potential environmental impacts. This study provides an overview of the integration between plant-wide models and LCA.
几十年来，人们一直强烈关注减轻废水处理厂（WWTP）的温室气体（GHG）排放。已经开发了许多模型来测量排放量并提出量化方法。现有研究着眼于温室气体排放与运营成本（OCI）之间的关系，这是决策者最重要的指标之一。其他可能影响控制策略的参数包括出水质量（EQI）和总环境影响。全厂模型是检验 OCI、EQI 和温室气体排放的可靠方法，而生命周期评估（LCA）则用于评估潜在的环境影响。事实证明，结合 LCA 和全厂模型是评估和比较 WWTP 最佳性能策略的有用工具。在这项涉及 WWTP 的研究中，基准模型被用于 LCA 作为决策工具，以找到最合适的处理策略。LCA 增加了额外的标准，补充了此类模型提供的现有标准。提出了一种针对全厂模型的成本/性能标准的补充方法，包括基于 LCA 的环境评估，这为 WWTP 提供了更全面的评估。它可以同时捕捉动态效应和潜在的环境影响。本研究概述了全厂模型与 LCA 的整合。
