退役硫酸厂场地土壤污染状况调查研究

Investigation and Research on Soil Pollution Status of Decommissioned Sulfuric Acid Plant Site

随着工业化进程的深入推进,我国产业转型速度加快,大量工业企业搬迁或关停,遗留了很多污染场地。本文选择六安市某退役硫酸厂作为研究对象,采集土壤样品,测定了样品的pH以及其他特征污染物,分析了重金属污染物在该区域土壤中的水平与垂直分布特征,查明了土壤重金属污染现状。结果表明,研究区域土壤主要受到砷、钴、钒的污染;重金属污染严重区域主要集中在生产车间和尾矿堆;土壤中重金属污染最深为1.5 m,主要集中在1.0 m以内。研究结果和调查方法可以为同类场地的污染状况调查提供参考。

With the deepening of the industrialization process,the speed of my country’s industrial transformation has accelerated,and a large number of industrial enterprises have moved or shut down,leaving many contaminated sites.This paper selects a decommissioned sulfuric acid plant in Lu’an City as the research object,collects soil samples,and determines the pH and other characteristic pollutants of the samples,and analyzes the horizontal and vertical distribution characteristics of heavy metal pollutants in the soil in this area,and ascertaines the current status of soil heavy metal pollution.The results show that the soil in the study area is mainly polluted by arsenic,cobalt,and vanadium;the heavy metal pollution areas are mainly concentrated in production workshops and tailings piles;the deepest heavy metal pollution in the soil is 1.5 m,which is mainly concentrated within 1.0 m.The research results and investigation methods can provide reference for the investigation of the pollution status of similar sites.
