摘　　要：[目的]研究光合细菌对废水中对硝基苯酚的降解。[方法]考察光照与溶解氧、pH值、通气量、菌体量、初始浓度等对硝基苯酚降解的影响。[结果]当对硝基苯酚浓度为100mg/L时,在光照曝气、pH8.0、通气量1.25vvm、菌体量15%的条件下,光合细菌降解对硝基苯酚的效果最好,12h后对硝基苯酚的降解率为100%。降解反应动力学研究显示,米氏常数Km为64.04mg/L,最大反应速度Vm为20.92mg/(L.h)。[结论]光合细菌在硝基苯酚废水处理中具有良好的应用前景。[Objective] The aim was to study degradation of 4-nitrophenol by photosynthetic bacteria in waste water.[Method] The effects of illumination,dissolved oxygen（DO）,pH,aeration rate,biomass content,4-nitrophenol concentration were investigated [Result] The results indicated that optimal conditions for degradation of 4-nitrophenol by photosynthetic bacteria were 100 mg/L of initial 4-nitrophenol concentration,illumination,pH 8.0,aeration rate 1.25 vvm,15% of biomass content,and the degradation rate of 4-nitrophenol reached 100% after 12 h.It was found that Km was 34.95 mg/L,Vm was 12.21 mg/（L·h）.[Conclusion] Photosynthetic bacteria had good application foreground in the treatment of nitrophenol waste water.
