Description

technical field

[0001] The invention relates to a phytoremediation technology for polluted environment, in particular to a method for remediating soil polluted by heavy metals by using hyperaccumulator phytoremediation. technical background

[0002] There are usually two ways for heavy metals to pollute soil: one is the environmental pollution caused by metal mining activities. Serious soil; heavy metal polluted soil caused by leaching and other reasons during the stacking of mining waste rocks; soil pollution caused by mine wastewater containing high concentrations of heavy metals, etc. The second is heavy metal polluted soil caused by industrial sewage irrigation of farmland. The phenomenon of lead-contaminated soil is relatively common in some parts of my country, and it is especially serious in some non-ferrous metal mining areas and surrounding areas of smelters in Yunnan Province. The average lead content in the soil of a typical non-ferrous metal mining area in south...
