Problems solved by technology
[0004] At present, the soil treatment methods of heavy metal pollution include physical methods, chemical methods and microbial treatment methods, but the current equipment for heavy metal-contaminated soil is generally complicated enough, and the work efficiency is low, and it is impossible to quickly and effectively remove heavy metal elements and ions from the soil. Separated, and may cause secondary pollution
