To understand the influence of blending antibiotic filter residue on the combustion performance of municipal solid waste,this paper selected a typical streptomycin residue and studied the combustion characteristics and synergies of municipal solid waste mixed streptomycin residue by thermogravimetric analyzer.The kinetic characteristics of the samples were analyzed by the Kissen-Akahire-Sunose(KAS)method and Flynn-Wall-Ozawa(FWO)method,and the NO emission characteristics of the samples were studied by blended combustion experiments on a fixed bed.The results showed that when the mixture ratio was 10％,the flammability index of the sample increased by 9.7％,the comprehensive combustion characteristic index increased by 11.1％,and the average activation energy decreased by 6.9％.The synergistic effect of the mixed combustion process of the two substances is mainly the promotion on the combustion of fixed carbon.With the increase of the mixing ratio from 10％to 30％,the flammability index and comprehensive combustion characteristic index of the sample gradually decreased,the average activation energy gradually increased,and the synergistic effect changed to inhibit the combustion of fixed carbon.The concentration of NO emission increased with the increase of the mixing proportion of streptomycin residue,and the interaction between streptomycin residue and municipal solid waste further promoted the emission of NO.
