摘要：

NH3 and H2S emissions play an important role in the total odor emission during kitchen waste composting. In order to reduce odor emission, this study designed experiments to investigate the effects of nitrification inhibitor addition on H2S and NH3 emissions during kitchen waste composting. All experiments were performed in simulated composting device. The results showed that the addition of NaNO3 and ammonium molybdate can effectively restrain H2S emissions, while adding NaNO2 not only failed to restrain the H2S emission but increased the emission concentration. NaNO3 can be used as the first choice to control the H2S emission. The addition of nitrification inhibitors increased the pH of compost materials, from this the NH3 emission was increased during kitchen waste composting. In kitchen waste composting process, once adding nitrification inhibitors to reduce the H2S emission, it is bound to be the same time to strengthen the emission reduction measures of NH3.
