煤的微生物脱硫的实验研究

煤中硫的脱出可以减轻对环境的污染，而煤的生物充是很有前景的一种脱硫方法，利用空气搅拌法，研究了内蒙古自治区酸性矿井水、土壤液、城市污未和工厂废液对乌达雀儿沟煤中硫的脱出能力，经过２ｄ细菌２和１５ｄ脱硫，发现除城市污水外，其余的均能脱掉煤中部分硫，硫脱除率２６．９５－３８．７７％；而且，中性环境与酸性环境有着几乎一致的硫脱除率。

Experimental study on microbial desulfurization of coal

The removal of sulfur in coal may decrease environmental pollution.And microbial desulfurization of coal is very prosperous. The microbial desulfurization of Wuda Que er gou's coal was carried out in acid mine water,soil water,city sewage and factory outlet water of inner Mongolia by means of air agitations(blastiny and oscillating).After cultiviating bacteria for two days and desulfurization for 15 days,all but city sewage were observed to remove sulfur in coal to some extent. The desulfurization rate ranges from 26.95% to 38.77%. Furthermore,the desulfurization efficiency of pH at about 2 is almost identical with that of pH at about 7.
