黄河流域支流金堤河汛期水质变化分析及治理对策研究
Study on Water Quality Variation in Flood Season of Jindi River,A Tributary of the Yellow River Basin and Control Countermeasures
摘要
Abstract
In the flood season of 2021,Anyang City has many heavy rainfall processes,among which the precipitation of Jindi River basin in Hua County was 3.2 times that of the same period in previous years,resulting in significant deterioration of the water quality of Jindi River in the flood season.In this paper,single factor evaluation,average comprehensive pollution index,water environment carrying capacity evaluation and other methods were used to analyze the change of water quality in flood season in Jindi River.The results showed that the bearing capacity of Jindi River was overload in 2021.The water quality deteriorated continuously during heavy rainfall in flood season.The highest concentrations values of permanganate index,biochemical oxygen demand,ammonia nitrogen,total nitrogen and total phosphorus were found in the wet period.The pollutant discharge mainly comes from sewage treatment plant discharge and agricultural non-point source pollution.This paper focus on the influence of heavy rainfall on the water quality of Jindi River in flood season and the solutions,in order to provide technical support for Anyang City to further strengthen the protection of water environment in the Yellow River basin,do a good job in regional water pollution prevention and control,and solve the water environment problems of Jindi River.关键词
