| 摘 要： | 基于降雨对河流有机污染物稀释和降解的确定性数学模型,运用未确知数学中盲数等工具,对降雨期间的河流水质情况进行了研究。结果表明,由于降雨的影响,河流在丰水年丰水期的水质较枯水年枯水期得到明显的改善,自净能力得到很大的提高。同时,利用盲数运算方法得到了洋河3个断面对应不同可信度的COD浓度区间,其中对应最大可信度的COD浓度区间,可以为制定雨水对河道的清污作用方案提供理论依据。。

| Abstract: | Based on the ascertained model of the dilution and degeneration on the dystrophication from rainfall,river water quality during rainfall was studied through the way of blind number calculation of unascertained mathematics.The result showed that the river water quality in wet year was much better than which in low water year.Meanwhile,ρ_(COD) ranges of three sections in Yang river were gotten,from which the ρ_(COD) range corresponding to the biggest reliability can be used to institute the water pollution scheme during rainfall. |
