Provided are a rapid detection method for a condition of landfill leachate polluting groundwater and an application thereof. The rapid detection method includes: carrying out fluorescence detection on groundwater in a specific region of a landfill, and determining whether the groundwater is polluted according to a ratio of fluorescence intensities at specific excitation/emission wavelengths in a specific fluorescence region. The rapid detection method provided by the solution establishes characteristic fluorescence spectrum regions, fluorescence intensities and regular characteristics thereof of organic matters in leachate-polluted groundwater of a landfill in a fluorescence spectrum region, and can achieve the rapid detection of a condition of landfill leachate polluting groundwater by means of a portable fluorescence detector on site. The detection method provided by the solution is characterized by rapid detection, no need of chemical reagents, simple operation, high detection sensitivity and lower cost.

Rapid detection method for condition of landfill leachate polluting groundwater and application thereof

A method for repairing an organic polluted site includes the following steps: step 1, build a sunlight greenhouse; step 2, carry out pretreatment to the soil of the organic polluted site; step 3, perform a biological heap treatment on the pretreated soil; step 4, implement quality control on the biological heap for soil remediation. By constructing a sunlight greenhouse within the original site of organic pollution sites, placing a biological heap in the sunlight greenhouse for a biological heap treatment, using the heat accumulated in the sunlight greenhouse to promote the volatilization of volatile organic matters in the soil without causing secondary pollution, and meanwhile adding a microbial agent and a nutritional agent to the polluted soil to promote the degradation and conversion of adsorbed organic matters.
