This study aims to define effects of industrial wastewater treatment (IWT) and water recovery (WR) processes by using Life Cycle Assessment (LCA) and Environmental Life Cycle Cost (ELCC) methodologies. The functional unit was applied as 1 m³ of treated water. The environmental impacts were evaluated using CML-IA baseline and ReCiPe midpoint (H) impact assessment methods. According to the results, abiotic depletion potential fossil fuel (ADP_ff) (14.1 %), global warming potential (GWP) (9.6 %), marine ecotoxicity potential (METP) (43.9 %), photochemical oxidation potential (POP) (9.4 %), acidification potential (AP) (16.9 %) are main impact categories for CML-IA whereas human carcinogenic toxicity potential (6.6 %), human non-carcinogenic toxicity potential (6.8 %), and water consumption potential (81.2 %) are those for ReCiPe midpoint (H). The LCA results show that electrical energy is the dominant process with higher than 90 % of these main impacts except METP (17 %). WR process has remarkable benefits from the point of impact categories such as ADP_ff, GWP, POP, and AP. ELCC value of WR process is approximately 20 % higher than that of IWT process. As a conclusion, electricity consumption is the first step of more efficient energy use and the general and local authorities for industrial parks need to create an appropriate energy policy for wastewater treatment plants.

本研究旨在通过使用生命周期评估 (LCA) 和环境生命周期成本 (ELCC) 方法来定义工业废水处理 (IWT) 和水回收 (WR) 过程的影响。功能单元以 1 m ³处理水的形式应用。使用 CML-IA 基线和 ReCiPe 中点 (H) 影响评估方法评估环境影响。根据结果​​，非生物耗竭潜力化石燃料（ADP _ff) (14.1 %)、全球变暖潜能值 (GWP) (9.6 %)、海洋生态毒性潜能值 (METP) (43.9 %)、光化学氧化潜能值 (POP) (9.4 %)、酸化潜能值 (AP) (16.9 %) CML-IA 的影响类别，而人类致癌毒性潜力 (6.6 %)、人类非致癌毒性潜力 (6.8 %) 和水消耗潜力 (81.2 %) 是 ReCiPe 中点 (H) 的影响类别。LCA 结果表明，除了 METP (17%) 之外，电能是主要影响的 90% 以上。_{WR 流程从 ADP ff}等影响点类别中具有显着优势、GWP、POP 和 AP。WR 工艺的 ELCC 值比 IWT 工艺高约 20%。总而言之，电力消耗是提高能源使用效率的第一步，工业园区的一般和地方当局需要为污水处理厂制定适当的能源政策。
