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.

对废水处理厂的温室气体的生命周期评估和全厂模式的排放控制策略进行严格审查。

几十年来，人们一直对减少废水处理厂（WWTP）的温室气体（GHG）排放有浓厚的兴趣。开发了许多模型来测量排放并提出量化方法。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。可能影响控制策略的其他参数包括废水质量（EQI）和总体环境影响。全工厂模型是检查OCI，EQI和GHG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。LCA和全厂范围的组合模型被证明是评估和比较污水处理厂最佳性能的策略的宝贵工具。对于涉及污水处理厂的研究，使用基准模型，而LCA是寻找最合适治疗策略的决策工具。LCA添加了额外的标准，以补充此类模型提供的现有标准。提议对整个工厂模型（包括基于LCA的环境评估）的成本/绩效标准进行补充，该模型可以更好地对污水处理厂进行总体评估。它可以捕获动态影响和潜在的环境影响。这项研究概述了整个工厂模型与LCA之间的集成。这样可以更好地评估污水处理厂。它可以捕获动态影响和潜在的环境影响。这项研究概述了整个工厂模型与LCA之间的集成。这样可以更好地评估污水处理厂。它可以捕获动态影响和潜在的环境影响。这项研究概述了整个工厂模型与LCA之间的集成。
