| 摘 要： | 水环境容量测算是实施总量控制的前提,其大小与污染控制的模式有关.以四川省西南地区某河流的一段为例,在一维稳态条件以及两种计算单元划分依据下(以控制断面或概化排污口所在断面为节点),用段首法、段尾法以及控制断面法三种不同的污染控制模式进行水环境容量测算.测算结果表明:段首法最为严格,适于经济发达地区、水源地或旨在改善水质...

| Abstract: | Comparative study was carried out on a certain section of a river with regard to water pollution control in order to estimate its assimilative capacity under different contexts,i.e.,section-head control,section-end control and cross-section control.Based on the one-dimensional steady-state modeling and two different divisions of calculation unit,the authors found section-head control would give the most rigorous result in terms of the assimilative capacity,which meant it's suitable for pollution control in ... |
