英文: Abstract: In this paper,river water quality prediction is integrated with water pollution control measures.Two parameters,water environmental capacity and Pollution Index are selected for pollution control measures.The objective is achieved after the deve
中文: 文摘:本文将水质预测及水污染控制措施有机地结合,选取水环境容量和污染指数作为水污染控制的参数.这样,一维对流-扩散水质方程的求解除就是实现本研究目的的关键.本研究采用的模型在现有的水质模型基础上有所改进,因为其采用四点隐格式对水质进行预测,推求可接纳污染物的环境容量值及为保证水质而限定的污染物浓度值,从而制定相应的水污染控制措施.为整体考虑各种污染物的情况,建议采用河流的污染指数进而推求综合污染指数.总之,本研究为水质保护提供了科学的计算方法,该法对水污染控制及污水对河道水质的影响是实用有效的.
