Abstract

Abstract:

As an effective remediation method for heavy metal pollution of soil，solidification remediation technology has become more mature and been widely used due to its low investment，quick response，simple operation and other advantages.Xiangtan manganese mine had rich manganese reserves and greatly promoted the economic development of Xiangtan area.However，the exploitation of mineral resources and the disorder accumulation of manganese residues result in the environmental problems of soil heavy metal pollution in Xiangtan manganese mine area.In order to explore the solidification remediation effect of solidification remediation technology on heavy metals in soil of Xiangtan manganese mine area，in the experiment，quicklime（CaO） and hydroxyapatite（HAP） were selected as curing agents to study the curing effect of their single and combined treatments on manganese（Mn），lead（Pb） and chromium（Cr） in the soil of Xiangtan manganese mine area.The specific research process is as follows：First of all，the soil samples were taken from the surrounding land of Xiangtan manganese mine（27°78′N，112°47′E），the soil at the depth of 0~20 cm was collected from five different sites and mixed evenly，and then brought back to the laboratory，the relevant parameters of the soil and the contents of Mn，Pb and Cr in the soil were determined.Secondly，0.10 mol/L hydrochloric acid reagent was used to extract effective Mn，Pb and Cr from soil，and the content was determined.Thirdly，the effect of curing treatments on the content of available Mn，Pb and Cr in soil was explored through variance analysis and correlation analysis.The results manifested that the content of available Mn and Pb in soil could be decreased significantly（p<0.01） by all curing treatments.The single curing treatments of CaO could reduce the content of available Cr in soil significantly（p<0.01），and there was a significantly（p<0.01） negative correlation between the dosage of CaO and the content of available Mn in soil，the application dosage of HAP had a significantly（p<0.01） negative correlation with the content of effective Mn and Pb in soil.The results show that the single and combined treatments of the two reagents have a good curing effect on available Mn and Pb in the soil of Xiangtan manganese mine area，and the single treatments of CaO generated good curing effect on available Cr in the soil of Xiangtan manganese mine area.

Key words: Xiangtan manganese mine area, heavy metal pollution, quicklime, hydroxyapatite, single treatments, combined treatments
