【摘要】 采用包埋复合菌处理抗生素废水中的COD,考察了不同因素对COD去除效果的影响,并对处理过程的动力学进行了初步的研究。结果表明,包埋固定化增强了复合菌抵抗极端条件的能力,使得复合菌处理抗生素废水的最适温度、pH和进水COD范围变宽。在最适条件下,经过6d的处理,包埋复合菌对抗生素废水中COD的去除率能达到60%左右,且处理COD的动力学过程可用幂函数进行模拟。更多还原

【Abstract】 Embedded-immobilized compound bacteria have been used for treating the COD of antibiotic wastewater.The effects of different influencing factors on COD removing efficacy are investigated.The dynamics of treatment course is studied.The results indicate that embedding-immobilization enhances the resistibility of compound bacteria to extreme conditions,so as to broaden the ranges of optimum temperature,pH and influent COD concentration.Under the optimal conditions,after a 6-day treatment,the embedded-immobilized compound bacteria could remove 60% of COD from antibiotic wastewater.The dynamics course of treatment process could be simulated by power function.更多还原
