Advanced redox in-situ treatment system and method for restoring polluted soil

The invention discloses an advanced redox innocent treatment system and method for waste pollutants, belonging to the technical fields of pollution treatment and restoration and environmental protection. The innocent treatment system comprises a waste degradation subsystem, a waste liquid treatment subsystem, an ozone water preparation subsystem, a degradation reagent addition subsystem, a detection control subsystem and a water level control subsystem. The method comprises the following steps: determining the type of waste pollutant, selecting the degradation reagent, pouring the waste pollutant into a treating pond, carrying out advanced redox treatment on the waste pollutant, carrying out innocent treatment on the treated waste liquid, reutilizing, and carrying out biodegradation treatment on the treated soil. The system and method have the advantages of obviously higher degradation efficiency and short time consumption, can treat organic pollutants within 2-3 days, can treat heavy metal pollutants within 3-5 days, greatly shorten the pollutant treatment time, and lower the cost by more than 70%.
