摘要
为达到对填埋气进行加工的下游生产流程的要求,需要对填埋气进行净化,特别是要求总硫体积分数脱到1×10-6甚至0.1×10-6以下。使已经粗脱硫的填埋气依次经过铁系颗粒段和改性炭系颗粒段进行精脱硫,实验结果表明:总硫(包括无机硫和有机硫)体积分数能够脱到0.1×10-6以下。
In order to achieve the requirement of downstream processing of landfill gas,its purification is needed,especially,the total sulfur（including the inorganic sulfur and organic sulfur） should be off to 1 × 10-6 or even 0.1 × 10-6 below.The experiment was carried out on landfill gas of pre-desulfurization to let it pass through the section of particles with iron and followed by that of the modified activated carbon particles for fine desulfurization.The experimental result shows that the total sulfur can be off to 0.1 × 10-6 below.
