| 摘 要： | 运用生命周期评价(LCA)方法,以西安市北石桥污水净化中心的污水处理与再生利用全过程为例进行环境影响评价,通过清单分析、当量计算和权重分析等一系列分析过程,计算出污水处理过程的投入成本及污水再生处理前后对环境的影响,得出污水在经过处理后,能够很大程度上减小其对环境的影响,从而产生环境正效益。该研究明确了污水处理在环境保护中的重要地位,同时对优化污水处理与再生利用工艺过程具有重要的参考价值和指导意义。

| Abstract: | Life cycle assessment(LCA) is applied in this paper to evaluate the environmental impact of the whole process of urban wastewater treatment and reuse in Xi'an Beishiqiao Sewage Purification Centre.Inventory analysis,equivalent calculation and weight balance were used to calculate input costs and unified the environmental impacts before and after treatment.The conclusion is that after the sewage treatment,the environmental impact is greatly reduced.This paper defines the important position of sewage treatmen... |
