耐铅锌微生物对矿山酸性废水中Zn2+和pb2+吸附性能分析
Adsorption properties of microbe resistant to lead and zinc on Zn2+ and Pb2+ in acid mine drainage(AMD)
摘要
Abstract
With the strain T1 which separated from drains soil of certain lead-zinc ore dressing as the research object, the effect on strain T1 adsorbing Zn2+ and Pb2+ in AMD was investigated under influence factors such as the initial consistence of Zn2+and Pb2+, pH, time, temperature and cell concentration. The results indicate that, the maximum adsorptions of Zn2+ and Pb2+ respectively reach to 79.86% and 69.04%, given the optimization of both treatment effect and economic costs, meanwhile, the adsorption capacities are 26.62 mg/g and 6.9 mg/g, when the initial mass concentrations of Zn2+ and Pb2+ are individually 100 mg/L and 30 mg/L, the pH is 4.0, cell mass concentration is 3 g/L, time is 6 h and temperature is 30 ℃. The process of strain T1 adsorbing Zn2+ and Pb2+ is in line with Langmuir isotherm model under the mass concentration range of 25-125 mg/L Zn2+ and 10-50 mg/L Pb2+, which is priority to surface adsorption.关键词
