摘　　要：以硫酸烧渣制备ＳＷ型脱硫剂，并对其进行沼气脱硫的研究。结果表明：用ＳＷ型脱硫剂进行沼气脱硫效果显著，可使Ｈ＿２Ｓ含量从３０００～５０００ｍｇ／ｍ￣３降到２０ｍｇ／ｍ￣３以下，符合国家规定的指标，饱和后的脱硫剂可作为制取硫酸的原料。该法以废治害，化害为利，具有一定的环境效益和经济效益。SW type desulfurizer is made from sintered dross of sulfurous ore and applied to removal of H_2S from marsh gas.It is showm that SW type desulfurizer is very effective,can decrease eontent of H_2S in marsh gas from 3000～5000 mg/m￣3 to below 20 mg/m￣2, national standard is achieved,thesaturated desulfurizer is used as raw material in producing of sulfuric acid.The process makes use of waste material and changes harm into good,hasenvironmental and economic benefit to a certain degree.
