城市污水对环境的影响已经引起了越来越多的关注，污水处理能够很大程度上减小其对环境的影响，因此具有重要的意义。为了表征污水处理过程对环境改善的程度，采用生命周期评价方法。以西安市第三污水处理厂的污水处理过程为例进行投入成本和对环境影响的分析，最终得出一种评价污水处理过程单位成本环境效益的模型。明确了污水处理在现代社会的重要地位，为选择和优化污水处理工艺提供了方法。

The impact of urban wastewater on the environment has caused more and more attention, wastewater treatment can greatly reduce the impact on the environment, which is of great significance. In order to characterize the extent of the wastewater treatment process to improve the environment, life cycle assessment has been used to analyse the input cost and en- vironmental impact of Xi'an No. 3 wastewater treatment plant, eventually a model of evaluating the environmental benefits of u- nit cost of the wastewater treatment process is obtained, making clear the important position of wastewater treatment in modern society, to provide a method for the selection and optimization of wastewater treatment process.
