摘要
根据土壤中重金属元素含量的不同,可以将其分为轻度、中度和重度重金属污染。不同污染程度的土壤,其再利用价值,以及修复治理措施也存在较大差异。近年来,国内关于土壤重金属释放规律的研究较多,但是大多数都是在单一维度开展试验,例如温度维度、光照维度等,具有很强的局限性。为了进一步提高试验结果的参考性,需要同时模拟多个变量,这样才能让样品试验结果,更加接近于现实情况。本文介绍含重金属土壤强化模拟试验的基本流程,通过三次试验的对比,证明含重金属土壤强化模拟试验方法的可行性。
According to the different contents of heavy metals in soil, it can be divided into light, medium and heavy metal pollution.There are also great differences in reuse value and remediation measures of different contaminated soils. In recent years, there have been many studies on the release of heavy metals in soils in China, but most of them are carried out in a single dimension, such as temperature dimension and light dimension, which have strong limitations. In order to further improve the reference of the test results, it is necessary to simulate multiple variables at the same time so as to make the sample test results closer to the reality. In this paper, the basic process of soil strengthening simulation test with heavy metals is introduced firstly, and then the feasibility of soil strengthening simulation test method with heavy metals is proved by comparison of three tests.
