某市工业源重金属污染源评价

针对某市工业源废水中6种重金属污染物产生现状,利用全国第一次污染源普查云南省数据,用等标污染负荷法计算出各种重金属污染负荷和负荷比,及每个工厂(地区)总的重金属污染负荷和负荷比,对某市工业废水重金属污染源进行评价,利用ARCGIS对该区域重金属产生量进行分析,明确重金属污染源空间分布规律,画出有重金属产生的企业的分布图,各种重金属产生空间分布图,和某市各乡镇的污染负荷等级图。结果表明该地区重金属污染源污染负荷的大小排列顺序是砷>汞>铅>六价铬>铬>镉。各企业的重金属源总污染负荷大小为化工厂>盐化昆明盐矿>盐化厂分厂>蓄电池厂>金属原料加工厂>电源厂>材料厂>废旧电瓶场>铸件厂。某市各镇的重金属污染源污染负荷大小排序为B镇>G镇>D镇>E镇。

Heavy Metal Pollution Evaluation from Industrial Sources in A City

Source of water for the peace of six Industrial emissions of heavy metals pollution status,using the first national pollution census data,Yunnan Province,with equal standard pollution load to calculate the pollution load of heavy metal pollution load and load ratio,and each plant(region),total heavy metal pollution load and load ratio of heavy metal pollution of industrial wastewater in A city to evaluate the use of heavy metals emissions in the region ARCGIS analysis,a clear spatial distribution of heavy metal pollution,emissions of heavy metals to draw a map of the distribution companies,all kinds of heavy metals spatial distribution of emissions.And A city of the township of pollution load level map.The results show that heavy metal pollution peaceful area the size of the order of pollution load is As>Hg>Pb>Cr(VI)>Cr>Cd.The company’s total pollution load of heavy metal the size of the source Chemical factory>Kunming Salt Mine salt>Salt Works factory>Battery factory>Metal Processing plants>Peace Power plant>Material factory>Used Battery field>Casting plant.Towns of heavy metal pollution with pollution load size in A city and then sort of town B town>G town>D town>E town.
