Abstract

The invention discloses an in-situ remediation method of polluted soil. The method comprises the steps of primarily drying the polluted soil by air; turning over the polluted soil after air drying, and synchronously spraying a soil remediation medicine to the turned-over soil; collecting soil samples of the turned-over and sprayed polluted soil after passing the preset remediation reaction time, and performing pollution detection on the soil samples; if the pollution detection result shows that the soil remediation is qualified, finishing remediation; if the pollution detection result shows that the soil remediation is failed, turning over and spraying the polluted soil again until the polluted soil remediation is qualified. According to the technical scheme, the method has the advantagesthat the remediation efficiency and the remediation effect of the polluted soil can be improved; and moreover, the processes are simple; and the cost is low.

Description

technical field [0001] The invention relates to the technical field of pollution remediation, in particular to an in-situ remediation method for polluted soil. Background technique [0002] At present, the irrational mining of mineral resources and their smelting discharge, long-term sewage irrigation and sludge application to the soil, atmospheric deposition caused by human activities, and the application of chemical fertilizers and pesticides have caused serious soil pollution. [0003] For the current soil pollution remediation technology, it can be divided into in-situ remediation technology and ex-situ remediation technology according to the classification of disposal site. In situ restoration technology can be further divided into in situ treatment technology and in situ control technology. Commonly used in situ treatment technologies include physical, chemical and biological methods. Ex situ restoration technology can be divided into excavation and ex situ treatment ...
