摘　　要：该文分析了生活垃圾与脱水粪渣协同焚烧处理效果,对焚烧系统运行情况,以及排放指标进行对比分析研究。在粪渣掺烧比例为5%,即单台焚烧炉协同处置粪渣48.44 t/d的条件下,焚烧系统炉温平均降低5℃左右。为确保焚烧烟气达标,烟气脱酸系统中熟石灰用量增幅超过30%。烟气、飞灰螯合物等排放浓度均低于规定限值,焚烧烟气中氮氧化物的浓度有所增加,重金属等指标能够达标排放。协同焚烧处置能够对粪饼起到无害化处理的作用,该处理方式可作为粪渣的应急处置。This paper showed the effect of co-incineration of domestic waste and dewatered feces,by comparing and analyzing the operation conditions of the incineration system and the emission indicators.Under the condition that the proportion of dewatered feces blended was 5%,i.e.48.44 t/d of dewatered feces was co-disposed in a single incinerator,the furnace temperature of the incineration system was reduced by about 5℃on average.The incineration flue gas met the standards,while the amount of slaked lime used in the flue gas de-acidification system was increased by more than 30%.The emission concentrations of flue gas and fly ash chelate were lower than the prescribed limits.The concentration of nitrogen oxides in the incineration flue gas was increased accordingly,while the mass concentrations of heavy metals were able to meet the emission standards.This research showed that co-incineration could be used as a harmless treatment and a kind of emergency disposal method of the feces.
