摘要
对落马湖的水质进行分析,结果表明其主要污染物为TN(总氮)、TP(总磷)和挥发酚等;结合化学需氧量、溶解氧和叶绿素a的值,利用综合营养状态指数法判定落马湖处于重度富营养化状态,水体在Ⅳ~Ⅴ类水质标准范围.湖中氮元素充足,藻类的生长速度取决于磷元素的含量,落马湖属于磷控制性湖泊.
Analyzed the water quality in Lake Luoma,the results indicate that its major contaminants are TN(total nitrogen),TP(total phosphorus)and volatile phenol.Based on the parameters of Chemical Oxygen Demand,Dissolved Oxygen and Chlorophyll a,the comprehensive trophic state index method are applied for assessing the eutrophication of Lake Luoma,and the results confirm that its water quality is heavy eutrophic.The water quality of Lake Luoma meets the level ofⅣtoⅤclassification of surface water environmental quality standards.The nitrogen in the lake is sufficient,and the growth of algae is controlled by the phosphorus.Water eutrophication of the lake is phosphorus-controlled.
