Abstract

Abstract

Reclaimed water has become one of the important ways to solve the water shortage because of its abundant water quantity， stable water source and less fluctuation by natural conditions. As a city with serious water shortage and high dependence on Yellow River water， efficient utilization of reclaimed water is particularly necessary and urgent in Yinchuan. However， as the application scope of reclaimed water continues to expand， its ecological and environmental risks are also gradually appearing. Based on the actual situation of reclaimed water utilization in Yinchuan， this study evaluated the potential ecological risks and proposed coping strategies for the specific situation of Yinchuan area， taking the cases and challenges of global reclaimed water application in the process of ecological water replenishment into account. The study explored in depth the three dimensions of water environment， water ecology and water security， and formulated ten feasible suggested measures， including formulating local regulations on reclaimed water utilization in Yinchuan City， Ningxia， reasonably determining the amount of reclaimed water to be recharged， planning a reasonable recharge cycle， upgrading the quality of the effluent from the reclaimed water treatment plants， reducing the discharge of trace pollutants， adjusting the disinfection measures for the effluent， maintaining the reclaimed water distribution system on a regular basis， real-time monitoring of hydrological conditions of recharged rivers and lakes， continuous tracking of the quality of receiving rivers and lakes and the quality of the soil of the irrigated green areas， and regularly assessing the water ecosystem health of the recharge rivers and lakes. Reasonable management and technical means will help to effectively control the ecological and environmental risks in reclaimed water utilization， promote the healthy development of reclaimed water utilization， and achieve the win-win goal of sustainable utilization of water resources and ecological protection.
