【摘要】 本文提出简单的一、二元稳态水质模型及污染带边界计算式;对模型参数的推算作了一些探索;在有密集排放口的清安河上游分别作了一元模型计算及一、二元模型联合演算,两法成果基本一致,故为了简化,全部采用一元稳态水质模型存清安河自上而下56公里河上进行连续演算检验,证明精度已符合要求,并进而用于预测该河设计水量条件下(较严重污染)及几种水质控制方案实施后可能的沿河水质分布.更多还原

【Abstract】 A simplified model of one-and-two dimensional steady-state water quality and an equation for calculating the boundary of polluted river areas are proposed. And some coefficients of the models have been studied. One-dimensional model caculation and one-and-two dimensional model calculation are carried out, respectively, on the upper stream of the Qingan River with densely distributed waste water effluents. The results of the two mothods are basically consistent with each other. For simplifiecation, one-dimensional steady-state water quality model is recommended. The one-dimensional steady-state water quality model has been verified on the 56km long reach of the Qingan River. It is proved that its accuracy answers the requirements and it is used to predict the probable distribution of water quality along the river under the condition of the design flow and of several schemes of water quality control.更多还原
