摘　　要：通过对城市生活垃圾焚烧处理各工艺环节进行具体分析,结果表明:垃圾焚烧系统宜采用机械分选预处理技术、热电联产的能源利用方式、半干法+烟气催化+布袋除尘的烟气处理技术及飞灰固化处理技术相结合。在补贴为140元/t的条件下,从项目投产年算起,流化床、炉排炉和气化熔融技术投资回收期分别为4、5、9 a,等离子体气化焚烧技术在运行年限中不能收回投资。若要推行气化熔融焚烧技术和等离子体气化焚烧技术,一方面可提高这2种技术的垃圾处理补贴,另一方面也可将其环境效益考虑进技术的综合效益。Each process of municipal domestic waste incineration was analyzed in detail.The results showed that the combination of mechanical separation pretreatment technology,cogeneration way of energy utilization,semi-dry ＋ flue gas catalytic ＋ bag filter technology,and fly ash solidification processing technology was best suited to waste incineration system.If the disposal subsidy is 140 RMB/t,the payback period of fluidized bed technology,grate furnace technology and gasification-melting technology is required to 4 years,5 years and 9 years,respectively.Plasma gasification technology cannot recoup their investment in the operating life.To implement gasification-melting incineration technology and plasma gasification incineration technology,waste disposal subsidies of 2 technologies should be improved on the one hand,the environmental benefits of2 technologies in the comprehensive benefits can be taken into account on the other hand.
