The invention provides a soil heavy metal passivation agent for remediation of soil contaminated by heavy metals and losing agricultural, industrial and commercial uses and the like. The method includes 1, contaminated soil mining; 2, medicament mixing; 3, soil backfilling; and 4, reuse of the ...
The electro-remediation method of soil contaminated by heavy metal was researched by means of experiment in this paper, and the characteristic and mechanism for distribution and migration of heavy metal under an electric field were analyzed too. The experimental results indicated that the concentrations...
Soil contamination by heavy metals constitutes an important environmental problem, whereas field applicability of existing remediation technologies has encountered numerous obstacles, such as long operation time, high chemical cost, large energy consumpt
The invention provides a heavy-metal-polluted soil remediation additive which is prepared from the following components in parts by weight: 85-92 parts of kaolin, 1-15 parts of sodium sulfide, 2-6 parts of ferric sulfate, 1-6 parts of magnesium-containing preparation, 5-10 parts of apatite...

The feasibility of treating a heavy metal-contaminated soil by means of a solidification/stabilization treatment consisting of a granulation process is discussed in the present article. The aim of the study was to attain contaminant immobilization within the agglomerated solid matrix. The soil under co...
Since heavy metals are nondegradable and strongly bonded in soils, remediation of heavy metal polluted soils by extraction is difficult and current extract... None - 《Journal of Soil Contamination》 被引量: 23发表: 2009年 Electrodialytic Remediation of Different Heavy Metal-Polluted Soils in Suspe...
will be selected and cultivated; soil heavy metal will be absorbed and enriched by macro fungi; multi-remediation technologies will be applied together; molecular biotechnology and genetic engineering technology will be integrated; and the effects of soil heavy metal pollution remediation will be ...
