摘要 以自制粉煤灰/生物质生物陶粒作为固定化硫酸盐还原菌(SRB)载体,研究不同初始pH值条件下,陶粒与SRB的相互作用对陶粒表面微环境pH值的影响、pH值对细菌生长和固定的影响,及对SO42-去除率的影响。加有陶粒的培养基pH值迅速趋向6.5~7.5,使陶粒表面微环境有利于SRB的生长,固定在陶粒上的SRB比对应悬浮的SRB菌样的SO42-的去除率高出10%左右,SO42-的最大去除率为77.20%。说明固定在陶粒上的SRB比悬浮的SRB活性强,SO42-的还原能力大,提高了SRB对酸性矿山废水的适应能力与处理效率。 Under the conditions of different initial pH values,using the bio-ceramisite with coal fly ash/ biomass made at laboratory as the carrier to immobilize sulfate-reducing bacteria(SRB),the mutual effects between ceramsite and SRB to the influence on the pH value of the micro-surface environmental of the ceramsite,the influence of pH value on the growth and settling of SRB and the removal rate of SO42-were studied.The pH value of the medium with ceramite quickly tended to 6.5 ~ 7.5,which was in favour of the growth of SRB.Sulfate radical removal of SRB immobilized on ceramsite was higher above 10% than suspension one,which could achieve 77.20%.Results showed that biological activity and sulfate radical reducing capacity of SRB immobilized on ceramsite were higher than suspension one,that could improved adaptive capacity and processing efficiency of SRB to acid mine drainage.
