摘要
煤中含有多种重金属元素,火力发电厂通过燃煤排放影响周围土壤中重金属元素的含量与分布,本文以Cu元素为例主要研究安庆市火力发电厂周围土壤中重金属元素的含量及其分布,分析火力发电厂对周围土壤中重金属污染的贡献程度。研究发现该区域重金属含量并未超过国家标准,但根据主导风向比较,Cu的含量以电厂为中心,随距离增加含量呈递减趋势,其他方向上无规律可循,说明电厂对周围主导风向上的土壤中铜含量有一定影响,但因投产不久影响不明显。
The coal contains many kinds of heavy metal elements.The fire-power station by the way of burn coal to affect the heavy metal elements,contend and distributing in surrounding soil.This article will take Cu for example to study the heavy metal elements,contend and distribu-ting all aroud the firepower station.It will also analyze what extend the firepower station pollute the surrounding soil.The study discover this area＇s keavy metal elements,contend doesn＇t exceed the country,standard.But according to the compare with the dominant direction of the wind.The Cu,contend take firepower station for a center,the diatance increase,the Cu,contend descend.However,the other direction have no regularity to follow,note the leading wind power plant on the surrounding soil on the copper content have a certain influence,but soon put into production was not obvious.
