摘　　要：为了掌握抗生素菌渣掺混对城市生活垃圾燃烧性能的影响,选取典型的链霉素菌渣,利用热重分析仪研究了城市生活垃圾掺混链霉素菌渣的燃烧特性和协同效应,采用Kissinger-Akahire-Sunose(KAS)法和Flynn-Wall-Ozawa(FWO)法分析了样品的动力学特征,并在固定床上进行掺混燃烧实验,研究了样品NO排放特征。结果表明:当掺混比为10%时,样品的可燃指数提高了9.7%,综合燃烧特性指数提高了11.1%,平均活化能降低了6.9%,2种物质混燃过程的协同效应主要表现为促进固定碳的燃烧;随着掺混比从10%增加至30%,样品的可燃指数和综合燃烧特性指数逐渐下降,平均活化能逐渐升高,协同效应转变为抑制固定碳的燃烧。NO排放浓度随链霉素菌渣掺混比例的增加而升高,且链霉素菌渣与城市生活垃圾之间的相互作用进一步促进了NO的排放。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.
