摘　　要：利用嗜酸氧化亚铁硫杆菌对典型川煤进行脱硫实验研究，考察了FeSO。质量、Tf菌接种量、处理时间、煤浆质量分数、煤粉粒度等因素对脱硫效果的影响，并对煤系嗜酸氧化亚铁硫杆菌（煤系Tf茵）和非煤系氧化亚铁硫杆菌（非煤系1rf茵）的煤炭脱硫效果进行了比较。结果表明：煤系Tf菌最优条件为：FeSO。质量为0，接种量为9mL，处理时间为28d，煤浆质量分数为10％，煤粉粒度为0．150～0．075mm，其脱硫率分别为43．35％、48．50％、49．36％、42．06％和57．71％；非煤系Tf菌最优条件为：FeSO。质量为1．12g，接种量为9mL，处理时间为28d，煤浆质量分数为10％，煤粉粒度为0．150～0．075mm，其脱硫率分别为20．60％、42．06％、50．64％、39．06％和53．30％。Study the Acidithiobacillus ferrooxidans desulfurization of typical Sichuan coal. Investigate the influence of FeSO4 inoculation amount, bacteria quantity, treatment time, coal slurry concentration and coal particle size etc. on desulfurization effect. In the experimental process, compare the desulfurization effect of different acidithiobacillus ferrooxidans. The optimized experiment conditions of coal series aeidithiobacillus ferrooxidans is,when the mass of FeSO4 is zero,desulfurization degree is 43. 35% ,which reaches 48. 50% while the bacteria inoculation amount is 9 mL. The desulfurization rate is 49. 36% ,42. 06% ,57. 71% respectively,when the treatment time is 28 days,mass fraction of slurry is 10% , particle size of pulverized coal varies from O. 150 mm to O. 075 ram. The optimized experiment conditions of non-coal series acidithiobacillus ferrooxidans is,when the mass of FeSO4 is 1.12 g, desulfurization rate is 20.60% ,which reaches 42.06% while the bacteria inoculation amount is 9 mL. The desulfurization degree is 50.64% ,39.06% ,53.30% respectively under same conditions of those of coal series acidithiobaeillus ferrooxidans.
