摘要
考察了不同接种时间、矿浆浓度、氮源、催化剂对烧渣脱硫效果的影响，还考察了铁精矿的脱硫情况。得出结论：在单因素下，前3天脱硫速度快，3—6天脱硫速度缓慢；接种菌的培养时间为72h，矿浆质量浓度80g／L，氮源硫酸铵1g／L，催化剂硝酸银0．02g／L等条件下脱硫效果较好，此时．处理3天后含硫量能从1．07％降至0．40％，脱硫率62．6％；对铁精矿（含铁65．30％）脱硫，处理4天后，含硫量从1．44％降至0．44％，脱硫率达69．4％，铁精矿满足冶炼要求。
The effects of inoculated time, pulp density and catalyst and nitrogen source on desulphurization result are investigated and desulphurization of iron concentrate is also investigated. The conclusions include ; under each single factor, the speed of dusulphurization is fast in the first 3 days, slow in the following 3 ～ 6 days; the conditions of desulphurization are best when the incubating time of inoculated bacterial is 72 hours, the pulp density is 80g/L, the amount of nitrogen source（ NH4）2SO4 IS lg/L and the amount of catalyst - AgNO3 is 0.02 g/L, in this way, the sulfur is reduced from 1.07% and the rate of desulphurizatlon is 62.6% after 3 days of treatment; to remove sulfur from iron concentrate（ Fe：65.30% ）, the sulfur is reduced from 1.44% to 0.44% and the rate of desulphurization is 69.4% after 4 days of treatment and the quality of iron concentrate meets the needs of smelting.
