摘要
借助混合率与保存率的概念,将累积流量模型应用到河流水质管理规划中,提出了一个新的可考虑横向扩散影响的规划模型,并将水质管理目标定在取水口水质达标上.模型应用结果表明,流域污水处理的优先区域因污染源和取水口所在岸边位置不同而异.与传统的只考虑河流断面平均水质达标的规划模型相比。
A river quality management model is proposed by applying the cumulative discharge model to the optimization of waste load allocation.Taking account the effect of transverse mixing in the tributaries and mainstream,the model is used to minimize the total wastewater treatment cost in a river basin while keeping the water quality at drinking water intakes meeting the environmental standard.The results of model application show that it could reflect the incomplete mixing to the strategy of river quality management and is proved to be superior to the traditional model.
