Leachate Treatment

Organics in leachate from municipal solid waste landfills are notoriously difficult to treat by biological processes. These organics have high ultraviolet absorbance and can interfere with the ultraviolet disinfection process at the wastewater treatment plant that receives leachate if the leachate flow contribution is large enough. With more wastewater treatment plants switching to ultraviolet disinfection, landfills face increased pressure to treat leachate further. This study used size exclusion chromatography, fluorescence spectroscopy and ultraviolet/Vis spectrophotometry to characterise the bulk organic matter in raw landfill leachate and the biorecalcitrant organic matter in biologically treated leachate from the same site. The results indicate that biorecalcitrant organics have the polyphenolic absorbance peak at 280 nm, fluorescence peak at 280 nm excitation and 315 nm emission, and molecular size range of 1000–7000 Da, all of which are consistent with lignin. The lignin-like nature of biorecalcitrant leachate organics is supported by the fact that 30%–50% of municipal solid waste consists of plant debris and paper products. These findings shed light on the nature of biorecalcitrant organics in leachate and will be useful for the design of leachate treatment processes and further research on leachate treatment methods.
