| 摘 要： | 利用红假单胞菌(R.S)和氧化亚铁硫杆菌(T.F)，对高硫煤表面预处理，进行浮选脱硫试验，重点考察了预处理时间、矿浆浓度、pH值、细菌浓度等因素对浮选脱硫效果的影响.结果表明：预处理时间、体系的pH值、矿浆浓度、细菌浓度等因素对脱硫效果有着显著的影响.红假单胞菌预处理时间15 min、矿浆浓度10 %，pH=7、菌液浓度1011个/L，氧化亚铁硫杆菌预处理时间10 min、矿浆浓度10%，pH=1~2时，脱硫效果最好.

| Abstract: | The floatation desulphurization experiments of high-sulfur coal for which surface pretreatment was made by utilizing rhodopseudomonas spheroides(R.S) and thiobacillus ferroxidant(T.F).The effects of pretreatment time,slurry concentration,pH values and bacterial concentration on floatation desulphurization were emphatically examined,with a result that all these factors play important roles on desulphurization results.One can obtain the best result when for rhodopseudomonas spheroides preparation time is 15 minutes,slurry concentration 10%,pH=7 and the number of bacterial per liter 10~(11),for thiobacillus ferroxidant preparation time is 10 minutes,pH=1~2. |
