为减少高硫煤矸石对环境的污染，并对其进行综合利用，研究了煤矸石粒度、pH、温度、接菌量、培养时间、干湿条件和振荡等条件对硅酸盐细菌分解高硫煤矸石的影响。结果表明：10．00 g 粒度为200目的煤矸石在硅酸盐细菌接种量为1．0×1017～1．5×1017 cfu/g、体系 pH7．0～8．0、25～30℃的条件下培养15 d，其有效磷、速效钾和有效硫的含量分别是原煤矸石的7．18倍、21．05倍和3．40倍，有效钙和有效硅的含量分别是原煤矸石的1．12倍和1．16倍。

Aiming at the serious environment pollution caused by abundant dumped coal gangue in Guizhou,the authors studied that silicate bacteria act on high-sulfur coal gangue to make invalid nutrient elements in gangue into effective.The factors which influence the decomposition effect of high-sulfur coal gangue such as the particle size of coal gangue,pH,incubation time,culture temperature,bacteria quantity,humidity and oscillation were studied.The results showed that the coal gangue possessed the best performance when the particle size of coal in 200 mesh,system pH 7.0~8.0,besides,the inoculation quantity of 1.0 × 1017 ~ 1.5 × 1017 cfu/g,culture temperature reached 30℃ for 15 days.The effective phosphorus,available potassium and effective sulfur contents of coal gangue were 7.18 times,21.05 times and 3.40 times relative to the original coal gangue;The effective calcium and effective silicon contents of coal gangue were respectively 1.12 times and 1.16 times relative to the original coal gangue.
