Water Environment Characteristics and Water Quality Evaluation of the Heihe River Water Diversion System in the Northern Foot of the Qinling Mountains
In order to study the water environment characteristics of the Heihe River water diversion system,this paper analyzes the quality of canal blended water and source water based on water quality monitoring data from 2021 to 2022 using single-factor and comprehensive water quality index evaluation methods.The results show that the overall water quality of the Heihe River diversion system is excellent,with the main pollution factors being total nitrogen,permanganate index,pH value,total phosphorus,and five-day biochemical oxygen demand.On a temporal scale,water quality is better in winter and spring than in summer and autumn.On a spatial scale,the hardness and alkalinity of water sources in the western region are higher than those in the eastern region.These research findings can provide scientific basis for urban safe water supply.
