摘　　要：通过向污泥中添加不同配比的石灰,经TG-MS实验,在线分析检测热解过程中析出NH3和H2S两种气体浓度的变化规律。实验结果表明,石灰对污泥热解过程中NH3和H2S的析出有较好的抑制作用,且添加占污泥干重30%的石灰,对NH3和H2S的抑制效果最好。Through adding different ratio of lime to the sludge,in the TG-MS experiments,the rule of concentration change of NH3 and H2S in the process of pyrolysis was online analyzed and detected. The results showed that lime had very good inhibitory effects on generation of two kinds of gas（ NH3 and H2S） in the sludge pyrolysis process,and adding 30% of the dry weight of sludge lime would produce best inhibition effect.
