Hazard characteristics identification of concentrates produced by domestic waste landfill site leachate treatment system
This study evaluated the source and disposal process of concentrated liquor produced by the leachate treatment system in the landfill site located at Guangzhou,Guangdong Province,to clar-ify the hazardous characteristics of the concentrated solution.According to the current identification of technical specifications and standard methods,the hazardous characteristics of concentrated solution produced during landfill were identified by gas chromatography-mass spectrometry analysis.The re-sults showed that the concentrations of inorganic elements and organic pollutants in the concentrated solution were low,and the acute toxicity estimated value(ATEmin)of concentrated solution was much higher than the standard toxicity limit.Thus,the concentrated solution was identified as normal pollutant which possess no hazardous characteristics.
