摘　　要：为探究不同光质对小球藻(Chlorella sorokiniana)脱氮除磷的影响,在红光、蓝光、白光、红蓝光交替照明下研究了其脱氮除磷效果。结果表明:在红蓝光交替照明下小球藻脱氮除磷效果最优,对COD、TN和TP的去除率分别为88.78%、97.93%和93.02%;装置出水NH3-N、TN、TP和COD的浓度分别为2.82 mg/L、7.04 mg/L、0.21 mg/L和27.86 mg/L,去除率分别为93.20%、84.15%、94.13%和85.15%;反应器中污染物的去除主要依靠平板光生物反应器和管式光生物反应器。因此,采用红蓝光交替照明模式能够提升脱氮除磷效果,为小球藻应用于污水深度处理提供技术参考。To investigate the effect of different light qualities on the nitrogen and the phosphorus removal of Chlorella sorokiniana,the effect of nitrogen and phosphorus removal was investigated under red,blue,white and alternating red and blue light illumination.The results showed that Chlorella sorokiniana was the most effective in nitrogen and phosphorus removal under alternating red and blue light illumination,and the removal rates of COD,TN and TP were 88.78%,97.93%and 93.02%,respectively;the concentrations of NH3-N,TN,TP and COD in the effluent of the device were 2.82 mg/L,7.04 mg/L,0.21 mg/L and 27.86 mg/L,and the removal rates were 93.20%,84.15%,94.13%and 85.15%,respectively;the removal of pollutants in the reactor mainly relied on the flat plate photobioreactor and the tubular photobioreactor.Therefore,the use of alternating red and blue light illumination mode can enhance the effect of nitrogen removal and phosphorus removal,and provide a technical reference for the application of Chlorella in deep wastewater treatment.
