摘要
利用具有解钾功能的硅酸盐细菌和具有解磷功能的巨大芽孢杆菌一起处理高硫煤矸石来生产煤矸石肥料,并研究了两种细菌的混合比例、高硫煤矸石的粒径、接菌量、体系的pH值、培养时间、培养温度、干湿条件、振荡等因素对制备煤矸石肥料的影响。研究表明：当巨大芽孢杆菌和硅酸盐细菌的混合比例为4∶1、煤矸石的粒径为60目、体系pH值为7.0~8.0、接菌量为3.0×1014~6.0×1014/g、30℃下培养9 d时煤矸石中的碱解氮、有效磷和速效钾的含量分别是原煤矸石的13.33倍、68.70倍和11.08倍;有效硫、有效钙和有效硅的含量分别是原煤矸石的3.60倍、1.32倍和1.24倍。
Aiming at the serious environment pollution caused by abundant dumped coal gangue in Guizhou, this paper studies that silicate bacteria （ GY03 ） and bacillus megaterium （ ACCC10011 ） act on high-sulfur coal gangue together to produce a new type of fertilizer. The factors which influence the preparation of gangue fertilizer such as the proportion of the two bacteria, the particle size of coal gangue, the inoculation amount, pH of the system, incubation time and culture temperature are studied. As a result, the experiment shows that the coal gangue fertilizer possesses the best performance when the mixing ratio of bacillus megaterium and silicate bacteria is 4： 1, the particle size of coal in 60 mesh, pH of the system is 7. 0-8. 0, besides, the inoculation quantity of 3. 0 x 1014-6. 0 x 1014/g, culture temperature reaches 30 ~C for 9 d. The readily available nitrogen, effective phosphorus and available potassium contents of coal gangue fertilizers are respectively 13.33 times, 68.70 times and 11.08 times relative to the original coal gangue; the available sulfur, effective calcium and effective silicon contents of coal gangue fertilizers are respectively 3.60 times, 1.32 times and 1.24 times relative to the original coal gangue.
