Secondary pollution prevention and soil reconstruction using ex-situ washing remediation technology for heavy metal contaminated soil
Ex-situ washing technology for contaminated soil is a remediation method that excavates contaminated soil from its original location, cleans it with a suitable washing agent, and then backfills or transports the clean soil to other locations. This technology is suitable for remediation of soil conta
