Zusammenfassung: | The invention provides an intelligent remediation process for heavy metal and organic matter combined contaminated soil, and relates to the technical field of soil remediation, and the remediation process comprises soil hydraulic screening treatment, leaching treatment, slurry filter pressing treatment, wastewater treatment, microwave treatment and waste gas treatment. The heavy metal concentration in the polluted soil is reduced through the technological steps of leaching treatment, slurry filter pressing treatment, wastewater treatment and the like, whether the heavy metal concentration of the leached soil reaches the remediation target or not is judged through online wastewater monitoring and PLC calculation, and the soil destination is controlled according to the judgment result. Organic matters in the polluted soil are degraded through the process steps of microwave treatment, waste gas treatment and the like, and waste gas treatment and up-to-standard emission are controlled by utilizing waste gas on-li |
