| 摘 要： | 以沈阳红阳三矿的煤样为研究对象，用氧化亚铁硫杆菌对其进行了生物直接浸出脱硫和生物预处理浮选脱硫的实验研究。结果表明，在煤样含硫（全硫）2.30%的条件下，用细菌浸出20d，可以使煤样的含硫量下降到1.20%，脱硫率达47.83%，当对煤样进行生物预处理浮选脱硫时，氧化亚铁硫杆菌菌液可明显改善脱硫效果，在适宜的菌液用量下，经过3～10min的预处理，可以使脱硫率比不经预处理时提高10%左右。 |

| Abstract: | This paper deals with the removing of pyritic sulfur from coal by means of biotechnology, which includes bioleaching and microbial retreat and floatation. The coal samples used , whose total sulfur was 2.30%, were taken from the Third Hongyang Mine in Shenyang. Through the process of bioleaching which lasted for 20 days, the total sulfur was reduced to 1.2% and the removing rate of sulfur was 47.83%. The suspension of thiobacillus ferrooxidans (T.f for short) can affect the desulphurizing results notably in the process of microbial retreat and floatation. Under the reasonable condition, the removing rate of sulfur can be increased by 10% or so in the period of microbial pretreatment which lasted for only 3 to 10 minutes. |
