| 摘 要： | 利用外热式下吸固定床气化实验装置，以空气为气化剂对五种不同性质污泥的气化特性进行了研究。结果表明，升高气化温度有利于提高气化气的品质，气化气中CO、CH4和H2的含量和气化气热值随气化剂流量的减小而增加。污泥厌氧消化过程使气化气品质降低；污水处理工艺对污泥气化气组成和热值亦产生影响，其中连续SBR工艺的未消化污泥气化气中CO、CO2的含量最高，而H2、CH4和CmHn的含量最低；活性污泥法的未消化污泥气化气中H2和CmHn含量最高；A2/O工艺的未消化污泥气化气中CO、CO2的含量最低，而CH4的含量最高，且三个污水工艺污泥的气化气热值依次升高。

| Abstract: | The air gasification characteristics of five different sewage sludges were carried out in an external heated downdraft fixed-bed.The results show that the higher gasification temperature can improve the quality of product gases,and the contents of CO,CH4,H2 and the lower heating value(LHV) of the gases decrease with the increase of air flux.Anaerobic digestion process of the sewage sludge reduces the quality of the gases which is also affected by wastewater treatment of the sludges.The contents of CO,CO2 in... |
