【摘要】 实验将黄孢原毛平革菌接种至含不同浓度（0,100,200,300,500μg/L）诺氟沙星和镉离子的固体培养基中，考察黄孢原毛平革菌对诺氟沙星和镉离子复合污染的耐受性。结果表明，诺氟沙星和镉离子对黄孢原毛平革菌有一定抑制作用，黄孢原毛平革菌对高浓度敏感性较强；以海藻酸钠、沸石粉等为载体固定化黄孢原毛平革菌，研究了固定化黄孢原毛平革菌不同条件下处理诺氟沙星和镉离子复合污染废水效果。实验结果表明，在投加量为8 g,葡萄糖浓度为10 mg/L,Mn²⁺浓度为0.1 mmol/L时，诺氟沙星和镉离子去除率较高，Cd²⁺去除率为82.11%,NOR去除率为90.42%。表明固定化黄孢原毛平革菌对重金属Cd²⁺和诺氟沙星复合污染的溶液具有一定耐受性，具备处理该类复合污染废水的应用潜力。更多还原

【Abstract】 The tolerance of Phanerochaete chrysosporium to the combined contamination of norfloxacin and cadmium ions was investigated by inoculating P.chrysosporium in solid medium containing different concentrations of norfloxacin and cadmium ions（0,100,200,300,500 μg/L）.The results showed that norfloxacin and cadmium ions had certain inhibitory effects on P.chrysosporium,and P.chrysosporium was more sensitive to high concentration.Sodium alginate, zeolite and other carriers were used to immobilize phanerochaete chrysosporium.The effects of immobilized P.chrysosporium on the treatment of wastewater polluted by norfloxacin and cadmium ions under different conditions were studied.The experimental results of influencing factors showed that an optimun norfloxacin and cadmium ions removal were available when the dosage was 8 g, the concentration of glucose was 10 mg/L and the concentration of Mn²⁺ was 0.01 mmol/L,the removal rate of Cd²⁺was 82.11%,the removal rate of NOR was 90.42%,it’s showed that the immobilized P.chrysosporium had a certain tolerance to the sdution of heavy metal Cd²⁺ and norfloxacin combined pollution, and had the potential of application in the treatment of this kind of combined pollution wastewater.更多还原
