一种全方位土壤重金属治理的环保技术

A Comprehensive Environmental Protection Technology for Heavy Metal Treatment in Soil

以江西南部某砒霜场污染土壤为研究对象,通过水平防渗+垂直防渗的方式建立原位处置场,再通过添加药剂的方式对污染土壤进行固化稳定化处理,经处理后达标的土壤即可运入原位处置场填埋,最终对原位处置场进行封场和覆土绿化,使原污染场地和周边自然环境融为一体。

Taking the contaminated soil of the arsenic trioxide yard in the south of Jiangxi praince as the research object,the in-situ disposal yard is established by means of horizontal anti-seepage and vertical anti-seepage,and the contaminated soil is solidified and stabilized by adding chemicals.After treatment,the soil can be transported to the in-situ disposal yard for landfill.Finally,the in-situ disposal yard is closed and covered with the soil for greening,so as to integrate the original contaminated site into the surrounding natural environment.
