清江恩施城区段水质降解系数及纳污能力研究

Analysis of Water Pollution Capability in the Enshi City Part of Qingjiang River under Measuring the Water Degradation Factor

根据清江流域恩施城区段河流特性,本文将COD和NH3-N确定为本次污染物分析指标,水质变化浓度计算水质降解系数,以近10年最小月平均流量作为设计流量,计算实际总纳污能力,比较分析在推荐水质降解系数下的总纳污能力,为清江恩施城区段水生态文明建设和水污染防治提供技术支撑。

According to the characteristics of rivers in the Enshi City section of Qingjiang River,COD and NH3-N were determined as the pollutant indicators in this paper.The measured water quality change concentration was used to calculate the water quality degradation coefficient,and the minimum monthly average flow rate in the past 10 years was used as the design flow rate to calculate the actual total pollution capacity.Then,comparative analysis the total pollution capacity of the river section in both cases of measuring water quality degradation coefficient in river and recommended water degradation coefficient,and provide technical support for water ecological civilization construction and water pollution prevention and control in the Enshi City section of the Qingjiang River.
