Decomposition of ammonia and hydrogen sulfide in simulated sludge drying waste gas by a novel non-thermal plasma

•A novel gliding arc discharge plasma was proposed to treat NH3, H2S and their mixture.•Removal efficiencies of NH3 and H2S strongly depend on the applied voltage and waste gas velocity.•Maximum removal efficiency is achieved at an applied voltage of 11kV and gas velocity of 4.72ms−1.•When NH3 and H...
