  • 摘要: 根据硫酸盐还原菌(SRB)的生物矿化原理设计了一套连续碱度产生系统(SAPS)反应器,以市政污水处理厂的活性污泥为SRB提供源,南方常见的香芋柄为有机物碳源,选用石灰石为反应器中碱度层填充物,进行实验室模拟SAPS处理酸性矿山废水(AMD)的应用研究,实验结果表明,SAPS处理酸性矿山废水的方法是具有技术可行的:SRB利用有机碳源生长代谢,产生碱度、还原SO42-和降解COD。最终废水pH从进水4.0左右上升到出水7.0左右;出水COD降低到约200 mg/L; SO42-还原为各种硫化物,其还原率约为61%;不同金属离子在有机层和碱度层发生反应产生沉淀,其中Fe2+、Cu2+和Zn2+的去除效率分别约为76%、78.5%和82%,而主要靠物理吸附作用的Mn2+去除率较低;初次模拟SAPS运行到56 d时,系统最终因有机碳源不足而各项指标不再改变。
    Abstract: A successive alkalinity producing system(SAPS) reactor including an organic layer and an alkaline layer was designed according to the bio-mineralization mechanism of sulfate-reducing bacteria (SRB). The organic layer was made up of the activated sludge got from the municipal wastewater treatment plant and henry steudnera tuber which is a common plant in South China. Natural limestone was chosen as the main filled substance in alkaline layer. The applied research about SAPS treating acid mine drainage (AMD) in the laboratory was done and showed that the method was practicable. During the growth of SRB using organic carbon, the sulphate would be reduced, the COD could be degraded and the pH would increase simultaneously. The results showed that the pH of effluent increased from around 4.0 to approximately 7.0, COD decreased to around 200 mg/L and the removal efficiency of SO42- reached 61%. In addition, as different metal ions precipitated in the organic layer and alkaline layer,the removal efficiencies of Fe2+, Cu2+ and Zn2+ were 76%, 78.5% and 82%, respectively. However, the removal efficiency of Mn2+ was only 30% since it was absorbed mainly by physical adsorption. Due to the absence of organic carbon source, the system finally ran out after 56 days of normal operation.
