| 中文摘要 |
| 从印染厂污水中筛选到7株高效脱色菌,其中Pse4、Pse29两菌在非固定化条件下,分别对10mg/L阳离子桃红FG、活性艳红K-2BP溶液在染料为唯一碳源、能源时,12d脱色80%以上。这2菌都属于假单胞菌属。将各菌等量混合进行脱色,没有协同作用。采用凹凸棒粘土颗粒或塑料环为载体固定化脱色菌,能大大缩短反应时间,提高脱色率。凹凸棒颗粒固定化柱在6h即对60mg/L混合染料脱色91%,是一种具有较高实用价值的固定化技术。 |
| 英文摘要 |
| Seven strains were isolated from the drainage of wastewater treatment plant of a textile factory. Each of these strains candecolor different dye in dye containing water.For example, Pse 4 and Pse29 could decolor more than 80% of the dye Basic Red 13 and the Reactive Red respectively in 12 days when 10mg/L dye in solution was used as sole source of carbon and energy for bacteria. These two strains belong to Pseudomonas.There were no conjunctive function when 7 strains were simply mixed for decolor of mixed dyes in water.However, these strains seem to cooperate effectively when they were immobilized on Attapulgus or plastic rings. Immobilized microbe on Attapulgus candecolor 91% of 60mg/L mixed dyes in 6h. It is supposed to be a good immobilization technology for practical use. |
