Analysis on Water Quality Characteristics of Leachate from Typical Landfills in Guizhou
A significant volume of leachate is generated during the landfilling process of municipal waste.To gain insights into the water quality characteristics and pollution status of landfill leachate in Guizhou,we select-ed 7 typical domestic waste landfills to analyze the water quality index of leachate,and evaluated the pollution level by using a single-factor evaluation method.Moreover,we conducted analyses on the organic functional groups and organic components in the leachate through Fourier transform infrared spectroscopy and three-di-mensional fluorescence spectroscopy.The results show that,the leachate from landfill in Guizhou exhibits cer-tain biochemical properties.The heavy metal pollution levels in 7 domestic waste landfills are all severe,and the comprehensive pollution index order is Pingtang＜Qianxi＜Tianzhu＜Panzhou＜Suiyang＜Renhuai＜Libo.The results of Fourier transform infrared spectroscopy indicate that,there are abundant types of organic functional groups in the leachate.The results of three-dimensional fluorescence spectroscopy further prove that,the dis-solved organic matter in the leachate is mainly humic-like substances.This study can provide data support for the treatment of landfill leachate.
