摘要

为了更好地掌握煤矿污染土壤现状,需要评估污染土壤修复方法的优劣,提出了基于形态法评估的矿区污染土壤修复方法,该方法在研究区域布设采样点采集煤矿污染土壤样品,并对采集获得的土壤样品进行进一步处理及测定,并采用形态法对处理、测定后的矿区污染土壤样品中的污染物进行形态分级,实现了煤矿污染土壤修复评估;在此基础上,在模拟室温条件下,以煤矿区铅、锌重金属污染土壤为例,分析了不同P处理对煤矿污染土壤pH和水溶性P的影响、不同P处理对煤矿污染土壤水溶性Pb、Zn的影响,以及不同P处理对煤矿污染土壤中交换态Pb、Zn含量的影响情况。
        In order to better grasp the status quo of contaminated soil in coalmines,it is necessary to evaluate the advantages and disadvantages of contaminated soil remediation methods. A method for remediation of contaminated soil in mining areas based on morphological method is proposed. This method is to collect sampling points from coalmines in the study area and collect samples from coal mines. The obtained soil samples were further processed and measured,and the morphological method was used to analyze the pollutants in the contaminated soil samples in the treated and measured areas,and the soil remediation evaluation of the coal mines was realized; on this basis,under simulated room temperature conditions Taking the lead and zinc heavy metal contaminated soil in coal mining area as an example,the effects of different P treatments on the pH and water-soluble P of coal mine contaminated soil,the effects of different P treatments on water-soluble Pb and Zn in coal mine contaminated soil,and the different P treatment pairs were analyzed. The influence of exchangeable Pb and Zn content in coal mine contaminated soil.
