【摘要】：構(gòu)建了基于正交設(shè)計(jì)-水質(zhì)模擬-方案評(píng)價(jià)的污染物總量控制方案的方法體系,并應(yīng)用于滇池流域.選擇TN、TP作為總量控制指標(biāo),將滇池流域劃分為6個(gè)子區(qū)單元,通過設(shè)計(jì)5水平(0%,5%,10%,15%,20%)6因素的正交試驗(yàn)表,得到25種不同削減方案;耦合EFDC模型模擬得到25種不同削減情景條件下湖泊水質(zhì)的TN、TP濃度分布,計(jì)算各方案綜合營(yíng)養(yǎng)狀態(tài)指數(shù)(TSI),篩選符合中度富營(yíng)養(yǎng)化標(biāo)準(zhǔn)(60TSI(Σ)≤70)的方案,引入數(shù)據(jù)包絡(luò)分析(DEA)計(jì)算各方案的效率得分,得分最高的方案為最優(yōu)削減方案.研究表明,滇池的葉綠素a平均濃度與TP平均濃度具有極強(qiáng)的相關(guān)性,最優(yōu)方案下滇池流域6個(gè)子區(qū)TN、TP在原排放量的基礎(chǔ)上,削減比例均為20%,15%,10%,5%,0%,20%.
[Abstract]:The method system of total pollutant control scheme based on orthogonal design-water quality simulation-scheme evaluation was constructed and applied to Dianchi Lake Basin. TNT TP was selected as the total control index. Dianchi Lake Basin is divided into 6 sub-area units. By designing an orthogonal experimental table of 5 levels, 10 and 10 and 20 and 6 factors, 25 different reduction schemes are obtained. The combined EFDC model was used to simulate the concentration distribution of TNT in lake water under 25 different reduction scenarios, and the comprehensive nutritional status index of each scheme was calculated. According to the medium eutrophication criterion (60TSI (危) 鈮，
