中文摘要：

研究黑曲霉真菌和假单胞菌对模拟废水中Pb^2＋、Hg^2＋、Cu^2＋和Zn^2＋的吸附，结果表明：实验条件下，4种金属的最佳质量浓度吸附范围是60～80mg／L；在同一浓度情况下，4种金属离子的去除率大小为Zn^2＋〉Pb^2＋〉Cu^2＋〉Hg^2＋；黑曲霉真菌和假单胞菌最适合的加菌总量为10％（体积分数）；取样时间为20min；废水中的菲、芘、苯并（a）芘时Pb^2＋、Hg^2＋、Cu^2＋和Zn^2＋的去除均有一定的影响，影响强弱顺序为菲〉芘〉蓉并（a）芘：对4种金属离子的最适合的吸附温度差25℃。

英文摘要：

The biosorption of Pb^2＋、Hg^2＋、Cu^2＋ and Zn^2＋ ions was investigated by the fungus Aspergillus niger and Pseudomonas. The result showed that the optimal concentration range of the four heavy met al ions was 60～80 mg/L; removal rate of the four heavy metals followed the order： Zn^2＋ 〉 Pb^2＋ 〉 Cu^2＋ 〉 Hg^2＋ ; total adsorbent dose of the two microorganisms was 10 %, and the optimal biosorption time was 20 min;Phenanthrene, pyrene, benzopyrene could influence the removal rate of the four irons, and the order from strong to weak effect was ： phenanthrene 〉 pyrene 〉 benzopyrene; the optimal biosorption temperature was 25 ℃.
