摘要
为深入研究唐山市老自行车厂场区六价铬污染机理和确定治理方案,本文通过一系列的浸泡和土柱试验,查明了六价铬在场地包气带中的污染原理和硫酸亚铁还原固定治理土壤六价铬污染的可行性与相关参数。试验结果表明:污染场地内包气带中六价铬的运移主要受吸附和解析作用的控制。使用PH值为3.0,质量浓度为2.4%的硫酸亚铁溶液作为治理药剂,可将污染场地包气带中93.24%的六价铬去除。
In order to study the chromiumⅥ pollution mechanism in the old bike factory area in Tangshan and determine the treatment method,this paper comes out with the mechanism of chromiumⅥ pollution in the aeration zone of the site and the feasibility of the ferrous sulfate reduction in the treatment of the chromiumⅥ pollution of the soil as well as its relevant parameters.The experiment shows that the migration of chromiumⅥ in the aeration zone of the polluted site is mainly controlled by the adsorptions and resolutions.The ferrous sulfate solution,with a PH of 3.0 and mass concentration of 2.4%,can eliminate 93.24% of chromiumⅥ in the aeration zone of the polluted site.
