Abstract:BACKGROUND
Efficient pretreatment is key to improving landfill leachate biodegradability. This is the first study to combine hydrodynamic cavitation (HC) and potassium ferrate (K2FeO4) for the treatment of landfill leachate, using chemical oxygen demand (COD) and UV absorbance at a wavelength of 254 nm (UV254) as the main test indicators. The feasibility of HC combined with K2FeO4 as a mature leachate pretreatment method was explored.
RESULTS
The HC experiment used 40 L of mature landfill leachate raw water, w… Show more
“…In our previous study, 44 HC was used in combination with other AOPs (K 2 FeO 4 ) to treat landfill leachate. A Fourier-transform near-infrared spectrometer (FT-IR) was used to detect and analyze the freeze-dried samples of the stock and treated leachate solutions.…”
A new method of coagulation and hydrodynamic cavitation/chlorine was proposed to treat landfill leachate, and the combination treatment can significantly reduce the organic load of landfill leachate and improve its biodegradability.
