| 摘 要： | 研究了啤酒酵母对废水中镉离子的生物吸附过程，分析了啤酒酵母吸附镉离子的速度、pH、温度等的影响。实验表明，啤酒酵母对镉离子的吸附时间短（15min）；pH值范围宽（4～8）；酵母的单位吸附量大（46．5mg／g）。对于高浓度的含镉废水，酵母具有较强的吸附能力；废水经二次吸附处理后均能达到排放标准。用啤酒废酵母作为重金属离子的吸附剂，可提高啤酒企业的附加值和科技含量，也可降低啤酒企业排放废水时对环境的污染。（孙悟）

| Abstract: | Biosorption of cadmium in wastewater by beer yeast was studied.Influencing factors on the removal of Cd ions were analyzed such as absorption speed,pH,and temperature etc.The experiments indicated that the absorption time was short(15 min) and the absorption quantity per unit beer yeast was high(46.5 mg/g) with pH range between 4 to 8.The wastewater containing high concentration Cd ions treated by beer yeast absorption twice was in accord with discharge standards.The application of beer yeast to absorb heavy metal ions could increase the additional value of breweries and reduce the environmental pollution. |
