| 中文摘要 |
| 以凹凸棒粘土颗粒为载体,混合固定化筛选出的7株高效脱色菌,组装成固定化微生物反应柱。该生物柱对各种染料废水均有良好的脱色作用,在染料为唯一碳源和能源时,对60mg/L的混合染料6h能脱色91%,对于用染槽废液与食堂废水配制的实际废水,能在72h的连续流动状态下,保持80%以上的脱色率。固定化微生物柱的脱色机理是凹凸棒颗粒对染料的吸附和细菌对染料的降解的双重作用。 |
| 英文摘要 |
| A experimental system including water pump,air pump,flowmeter and a Plexiglas column etc.for treatment of dye containing water was set up.The key element of the system was the immobilized microbe column which was 100cm high and 6 8cm in diameter and packed with granulated Attapulgus clay (3—5mm),on which microbe were immobilized.Solution containing different kinds of dyes can be decolored by the system.For example,solution of mixed dyes could be decolored 91% in 6h when 60mg/L dye was used as the sole source of carbon and energy.Real dying wastewater mixed with kitchen drainage could be decolored more than 80% continuously in 72h by this system.The decoloring is supposed to be a combining function of degradation of microbe and adsorption of Attapulgus. |
