摘要
煤中硫的脱出可以减轻对环境的污染 ,而煤的微生物脱硫是很有前景的一种脱硫方法 利用空气搅拌 (鼓风与振荡 )法 ,研究了内蒙古自治区酸性矿井水、土壤液、城市污水和工厂废液对乌达雀儿沟煤中硫的脱出能力 经过 2d细菌培养和 1 5d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 2 6 95%～ 38 77% ;而且 ,中性环境 (pH≈ 7)与酸性环境 (pH≈ 2 )
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.
