Abstract

The disclosure is a method for recovering groundwater contaminated with organic phenols. The method includes the step of injecting a remediation agent into the groundwater extracted from the stratum to be rehabilitated or ex-situ extracted, followed by the step of injecting manganese-based oxidant. By adding a suitable proportion of soluble silicon to the water to be treated as a remediation agent, the efficiency of manganese-based oxidant in the treatment of phenolic pollutants is enhanced based on interface properties and stability of various manganese oxides in the regulating and recovering process. The method for recovering groundwater contaminated with organic phenols provided by the disclosure has a simple process and is convenient to operate, the adopted chemicals are inexpensive and easy to obtain, cause little corrosion to the injection equipment, and has a wide range of applications in practice. The adopted oxidant will not produce halogenated toxic by-products during the treatment process.
