以CMC-膨润土作为原料，运用包埋法将从活性污泥中驯化出的菌株进行固定，并对其对对硝基苯酚的降解性能进行研究。结果表明：固定化高效菌降解对硝基苯酚的最佳温度为35℃；随着对硝基苯酚初始质量浓度的增加，对硝基苯酚达到降解平衡所需要的时间逐渐增加；比较空白球株、CMC-膨润土包埋优势菌球株、游离菌3个系统对对硝基苯酚的降解，在35℃、120 r/min的条件下 CMC-膨润土对初始质量浓度为10 mg/L的对硝基苯酚降解率为74.28%；当废水中同时含有苯酚和对硝基苯酚时，该菌能以苯酚和对硝基苯酚为共代谢碳源。

CMC-bentonite was selected as a raw material to immobilize the strain isolated from the activated sludge and the process of degradation ofp-Nitrophenol with immobilized particles was studied. The studies indicated that the optimal temperature is 35℃ with the degradation ofp-Nitrophenol by ifxed efifcient bacteria. With increasing the initial concentration ofp-Nitrophenol, the time to reach equilibrium is increased. Through the comparative study of the immobilized beads without microorganism, the immobilized microorganism beads with CMC and Ca-bentonite, free strain, the results showed that the degradation rate ofp-Nitrophenol was up to 74.28%, when the initialp-Nitrophenol concentration was 10 mg/L. Phenol andp-Nitrophenol could be both degraded by the ifxed efifcient bacteria when they were both presented in the wastewater.
