ECOLOGICAL PROCESS OF WASTEWATER REGENERATION AND RECYCLING
Wastewater regeneration and recycling are essential means for developing unconventional water resources and reducing environmental pollutant discharge.However,in China,the regeneration and reuse efficiencies of wastewater remain low,and the energy and resource consumption for wastewater regeneration are relatively high,and the green circulation system has not yet been formed.This article,therefore,investigates and summarizes the ecological methods for wastewater regeneration from the perspectives of resources,environment,ecology,and safety.It outlines the relationship and implications of ecological treatment and ecologicalization treatment of regenerated water,analyzes the methods and key points for the ecological storage of regenerated water,and defines water quality conditions and environmental impacts for regenerating water resources.It discusses the ecological responses and risks of sensitive biological communities to regenerated water discharge and presents the main pathways to block pollutants'co-exposure risks.This article also elucidates the critical control factors for regenerated water as a key source of ecological water supply in urban surface water bodies,and proposes practical strategies for integrating regenerated water with aquatic ecosystems to promote ecological restoration.
