城市河湖再生水生态补水研究进展
Research Progress of Ecological Water Recharge with Reclaimed Water for Urban Rivers and Lakes
摘要
Abstract
[Objective]This paper aims to explore the specific impact of reclaimed water replenishment on urban water ecology and water environment,ensure the safe and efficient utilization of reclaimed water,and provide a reference for the research on the reuse of reclaimed water in urban rivers and lakes.[Methods]Based on the application practice and research result of reclaimed water in the field of ecological water replenishment for urban rivers and lakes,through the China National Knowledge Infrastructure(CNKI)and Web of Science databases,more than 40 000 literatures related to"reclaimed water","reclaimed water ecological replenishment","reclaimed water"and"reclaimed water recharge"are retrieved,and research and analysis are conducted from the perspectives of annual publication volume,research focus,development trends and frontiers.[Results]Ecological water recharge with reclaimed water affects key parameters such as flow rate and flow volume,and it may contain nutrients,heavy metals and new types of pollutants,which changes the water quality,and affects the growth rate and community structure of aquatic organisms.Related literature statistics show that the overall water quality of the receiving water bodies has improved after the implementation of measures such as increasing the recharge frequency,setting up additional recharge points or doubling recharge volume.[Conclusion]Ecological water recharge with reclaimed water can improve water quality,but its consideration of ecological health is relatively insufficient,and there are differences in the number of binding indices and thresholds of the various water quality standards and norms,which further increase the potential ecological environmental risks.And the setup and regulation of water replenishment factors affect the effect of reclaimed water replenishment.At the same time,future research should focus on exploring the mechanism of reclaimed water replenishment to improve the water environment,upgrading the sewage treatment technology,improving the evaluation system and constructing a smart management platform,to control the risk of water replenishment,guarantee the safety of the ecological environment,optimize the replenishment mode,and promote the healthy,harmonious and sustainable development of urban water ecology.关键词
