考虑取水口和支流的河流纳污能力计算模型研究与应用
Study on the calculation model of river water environment capacity considering water intake and tributary
摘要
Abstract
In order to provide technical support for total amount control of pollutants and for defining red lines of received-pollutant limits in water function areas,a stepwise summation model is built to calculate water environment capacity,which considers water intake and tributary based on one-dimensional water quality model.The water function area was divided into several reaches to calculate water environment capacity by the control section with sewage outlet,water intake or entrance of tributary.Comparing to the traditional model,this model could control the function area of water quality target neatly,and avoid water environment capacity too strict or too loose.The model was adopted to Shaanxi section of the Weihe River.The calculated results of water environment capacity by the new model,segment first control model and the section-end control model were 73814.43,36159.96 and 85365.49t/a,respectively.The results show that the new model is more modest and it could calculate water environment capacity between any two control sections.Because of considered intake,tributary and sectional velocity,water environment capacity is also more accurate and reasonable.The new model could provide technical support for the total amount control of pollutants and for defining the red lines of water functional areas.关键词
