海绵城市水体污染负荷频谱分析与污染生态修复方法研究

为了建设海绵城市,研究水体污染净化是十分必要的。因此提出海绵城市水体污染负荷频谱分析与污染生态修复方法研究。首先检测水体中各种污染物含量,计算水体污染负荷指数和对应的累积频率,以此绘制水污染负荷指数-累积频率关系图,得到海绵城市水体污染负荷频谱。然后,采用生态混凝土、光催化+沉水曝气、生态浮岛组成的综合生态修复方法进行污染生态修复。实验结果表明:修复后,修复系数均达到了0.8以上,水体中污染物大量减少,COD数值均大幅度下降,水质得到了明显改善。该研究达到了修复目的,具有实际应用性。

Study on effects and treatment of ocean oil pollution

Because of the special physico-chemical properties and toxicity of oil in ocean, it causes the acute and chronic toxicity in marine life, through food chain comes into human body, has a serious harm on human＇s health. This test analysis influence of oil pollution in ocean, provides theoretical guidance of governing.
