In the context of rapid economic growth and continuous population expansion,the virtuous cycle and sustainable utilization of water resources have attracted widespread attention.In the process of modernization construction in China,as an important measure to alleviate the shortage of water resources,there are certain objective obstacles to the promotion of recycled water reuse.The main reason for this is that investors generally pay attention to the economic benefits of recycled water reuse while neglecting environmental and social benefits,and urban residents have little understanding of the benefits of recycled water.This study established a comprehensive benefit evaluation system for recycled water based on economic evaluation method,which includes four aspects:resources,environment,society,and economy.The comprehensive benefit evaluation of recycled water was conducted by using Bishan District,Chongqing as an example.The results show that in 2021,the benefits generated from the utilization of renewable water resources in Bishan District are 30.837 6 million yuan,mainly environmental benefits,followed by resource benefits,economic benefits,and social benefits.The application practice taking Bishan District as an example has proven that the recycling of recycled water has rich hidden benefits,providing a theoretical research foundation and scientific basis for promoting the promotion of recycled water recycling in the region.
