固定化优势降解菌群处理制浆造纸废水

摘要

This study evaluated the treatment efficiency of pulp and paper effluent by immobilization of four dominant bacterial strains, which were screened by the method of statistical analysis. Results showed that the average removal of COD,, was 50. 34% (Agrobacterium sp. ) . 34. 57% ( Bacillus sp. ) , 57. 58% ( Gordonia sp. ) , 43.09% (Pseudomonas putida. ), respectively. High CODcr degradation (70. 87% ) was achieved by immobilization of four dominant bacterial strains, which was improved by 5. 57% comparing with the treatment by free bacterium.%利用统计学分析方法筛选得到优势降解菌群,然后对其进行固定化,并用于制浆造纸废水的处理.结果表明,固定化单株菌的CODCr,降解率分别为:50.3％(土壤杆菌)、34.6％(杆状菌)、57.6％(戈登氏菌)、43.1％(恶臭假胞杆菌)；而固定化优势降解菌群对制浆造纸废水的降解能力有所提高,CODCr降解率为70.9％,较游离菌群的处理提高了5.6个百分点.
