河道一維污染源控制反問題

摘要: 在天然河道一維水質(zhì)數(shù)值模擬中,對初始條件、邊界條件及污染源條件分別構(gòu)造基本解,以此為參數(shù)將任一斷面的污染物濃度表示為初始條件、邊界條件及各污染河段污染物排放量的線性函數(shù)。從模擬水域需滿足的水環(huán)境功能提出約束條件,以污水處理費用最小為目標(biāo)函數(shù),構(gòu)造污染源控制問題,并用遺傳算法求解。 Abstract: By simulating one dimensional water quality of naturalchannel,three groups of the basic solutions calculated from the initial pollutant concentration,the boundary pollutant concentration and the pollutant amount into channel,can be obtained respectively.Basing on the basic solutions,the pollutant concentration in any section of channel is expressed mathematically by a linear function of the pollutant amount.The optimization model for pollutant amount control is set up,in which the restraint conditions of the model are deduced from river’s environment plan and the object function of the model from the function of pollutant treatment fee.The genetic algorithm is used to solve the optimization model successfully. 作 者: 韓龍喜   作者單位: 河海大學(xué)水文水資源及環(huán)境學(xué)院,  期 刊: 水科學(xué)進(jìn)展  ISTICEIPKU   Journal: ADVANCES IN WATER SCIENCE  年,卷(期): 2001, 12(1)  分類號: X522 O242.1  關(guān)鍵詞: 河道    污染源控制    反問題    遺傳算法
