| 摘 要： | 对再生水补给河流后水质的风险状况进行分析,参考土壤的生态风险评价体系,构建新的水质风险等级制度,对由再生水补给的河流的水质进行风险管理.仿真结果验证了评价体系的有效性和可信性.新构建的风险评价体系不但反映了某一特定环境下各种污染物对水环境的影响,也反映了水环境中多种污染物的综合效应,并能运用定量方法划分出潜在生态风险程度,可为水质管理提供更好的参考和依据.

| Abstract: | Ecological risk of water quality was analyzed for the river recharged with reclaimed water.A new risk rating system of water quality was developed according to the soil ecological risk evaluation system,and ecological risk of water quality was managed.Simulation results verified the validity of the risk evaluation system.The new risk evaluation system not only reflected the impact of each kind of pollutant on the water environment respectively,and also reflected the combined effects from all pollutants on the water environment. The potential ecological risk degree was divided based on the quantitative methods, and this could provide better reference and basis for water quality management. |
