摘　　要：针对重庆市某地生活垃圾焚烧企业焚烧炉排放口烟气的监测数据进行了统计,选取镍、铜、锰等3种重金属排放浓度和5个影响因素,采用SPSS逐步回归法对重金属排放浓度影响因素进行了回归分析,建立了影响因素模型。结果表明:生活垃圾焚烧烟气中镍排放浓度受氧含量和一氧化碳排放浓度的显著影响,氧含量与镍排放浓度成反比,一氧化碳排放浓度与镍排放浓度成正比;烟气中铜排放浓度与氮氧化物排放浓度具有显著相关性,与其成反比;烟气中锰排放浓度与氧含量有显著相关性,与其成反比。Through the statistics of the monitoring data of the flue gas from the incinerator discharge of a domestic waste incineration enterprise in a certain place in Chongqing,the emission concentrations of 3 heavy metals such as nickel,copper and manganese and 5 influencing factors were selected,and the SPSS stepwise regression method was used to calculate the emission of heavy metals.Regression analysis was carried out on the influencing factors of concentration,and a model of influencing factors was established.The results indicated that the emission concentration of nickel in the exhaust gas had significant correlations with oxygen and carbon moNO_(x)ide emission concentrations.Furthermore,the oxygen emission concentration was inversely proportional to the concentration of nickel emission;the carbon monoxide emission concentration was proportional to the concentration of nickel emission.The emission concentration of copper in the exhaust gas had a great relationship with nitrogen oxides emission concentration,and inversely proportional.The emission concentration of manganese in the exhaust gas had a great relationship with oxygen emission concentration,and inversely proportional.
