- Abstract:
- Wastewater treatment can definitely improve the water environment and also cause other negative environmental impacts due to pollutant discharge and energy/resource input. As a tool comprehensively assessing the total environmental impact and also potentially alleviating the impact, life cycle assessment (LCA) has been widely used in wastewater treatment at home and abroad. However, imperfect and unreasonable target scoping and selection of evaluation parameters could result in unfair evaluation results and hinder LCA development space in sewage treatment field. Moreover, the lack of resource/energy recovery module in LCA would always make traditional sewage treatment technology undertake the negative name of its total environmental impact as a “pollution source”. Therefore, it is necessary to review the LCA progress of assessment theories and methods, to analyze the application status of LCA at home and abroad, to point out the LCA questions applied in China, and to summary the future development direction of LCA in wastewater treatment. Based on the review, it is expected to promote the wide application of LCA in China to realize the goal of “net-zero” environmental impact of wastewater treatment.
