Current situation and policy suggestions on the utilization of regenerated water in Chinese cities
The total amount of water resources in China is abundant,but the per capita occupancy is severely insufficient and urban water problems such as water shortage,low development and utilization efficiency,and deteriorating water quality are major issues that constrain economic and social development.Regenerated water has the characteristics of large total amount,abundant availability,low treatment cost,and stable water quality.It can increase water supply,reduce pollu-tion,optimize water resource allocation system,and improve water resource utilization efficiency.It is an important resource to address urban water problems.This article introduces the basic concept,classification,relevant national stand-ard system and implementation status of regenerated water,as well as the current utilization status of typical cities.It analy-zes the shortcomings and problems in the current use of regenerated water,and provides relevant suggestions for future poli-cy formulation of urban regenerated water utilization in terms of formulating policies based on local conditions and regions,fully leveraging the role of market regulation,establishing a sound policy and regulatory system and encouraging innovative development of regenerated water utilization technology.
