陕西某氧化锌冶炼企业拟退役地块污染特征调查研究

Investigation and study on pollution characteristics of plot to be decommissioned of zinc oxide smelter in Shaanxi province

针对陕西某氧化锌冶炼企业拟退役地块土壤环境质量进行了地块历史和现状调查、地块污染识别、土壤样品的采集及分析。通过研究污染物的回转窑烟尘浓度分布规律,分析厂区土壤环境中的铅、铜、镍、砷等重金属污染物的含量,最终确定拟退役地块为非污染地块,满足地块后期规划用途为工业用地的要求。

In this paper,the soil environmental quality of a certain zinc oxide smelter in Shaanxi province was investigated,the soil pollution was identified,and the soil samples were collected and analyzed.By studying the distribution law of the concentration of dust from rotary kiln and analyzing the contents of heavy metal pollutants such as lead,copper,nickel and arsenic in the soil environment of the plant,the proposed decommissioned land parcel was finally determined to be a non-polluted land parcel,which could meet the requirements of industrial land planned in the later period of the land parcel.
