摘要
通过微分方程的推导,提出了一个可估算具有非规则湖岸的排污口附近水域,水污染物浓度分布的湖泊水质扩散模式: C_i=C_0·exp{-(kHr^2)/(2q)[ω_1-(1-(R_1R_2)/r^2)△ω_1-…-(1-(R_(i-2)R_(i-1))/r^2)△ω_(i-2)-(1-R_(i-1)/r)~2/(1-R_(i-1)/R_i)△ω_(i-1)]}它考虑了因污水排入引起的平流输移和污染物降解的条件下得到的水质扩散微分方程的稳态解析解,是常用的降解物质湖泊水质扩散模式的推广,可适用于任意形状湖岸排污口附近水域水污染物浓度分布的估算。文章同时举例说明了模式的可行性。
Through differential equation inducing, a water quality dispersion model of irregular lake has been proposed:
This model was induced by considering the conditions of convection, purification of wastewater inflow and degradation of pollutants, then the stable state explanation of dispersion differential equation was obtained. This model is an extention of water quality dispersion model of irregular lake, which could be used for pollutants concentration distribution at the vicinity to any type of lake shore wastewater outlets.
