| 摘 要： | 本文利用胶质芽孢杆菌(Bacillus mucilaginosus)和黑曲霉(Aspergillus niger)处理铜-苯酚(简称铜-酚)和镉-苯酚(简称镉-酚)这类有机-无机复合污染模拟废水,采用胶质芽孢杆菌和黑曲霉分别单独、联合或先后处理等5种方式,探讨了这两类菌体对复合污染模拟废水的处理效果及优化方法。结果表明,微生物对铜-酚废水的处理效果优于对镉-酚废水。对于铜-酚废水的处理表明,当废水中苯酚浓度为50~200 mg/L时,去除率可达80%以上,最高可达94.65%,其中铜的去除率较苯酚低;当模拟废水中铜浓度为30 mg/L时,可达最高去除率(60.02%)。微生物对镉-酚废水的处理表明,当废水中镉离子浓度为4 mg/L时,最高去除率为58.44%,苯酚的去除率一直保持在30%左右。

| Abstract: | Bacteria and fungi were used to deal with organic-inorganic complex wastewater containing Cu2+(or Cd2+)and phenol.5 different experiment methods,a method of using single Bacillus mucilaginosus,a method of using single Aspergillus niger,a multi-step method of using both B.mucilaginosus and A.niger,a sequential methods of first using B.mucilaginosus as flocculant and then using A.niger in the degradation step and vice versa,were set up and explored.The results showed that the treatment efficiency for Cu2+-phe... |
