Impact Persulfate on COD Analyze and Possibility Use it as Oxidant of Leachate

Abstract

In this research, the performance of persulfate (PS) for the removal the chemical oxygen demand (COD) of raw leachate landfill was studied. The experiments were conducted in a batch reactor. The effects pH (2-11), PS/COD ratio (2-10), and reaction time (0-240 min) on the removal of leachate landfill. The Maximum removal efficiencies of COD and NH3 at optimize operational conditions (pH 4, PS/COD ratio: 6 and reaction time: 45 min) were 48.33% and 45.83%, respectively.
