摘　　要：通过在室外大型平板式光生物反应器中培养小球藻,来考察小球藻处理市政污水的能力。实验结果表明,小球藻在各个季节均对污水的脱氮除磷效果显著,总氮去除率达51.76%~97.66%,总磷去除率达79.37%~97.85%,处理后总氮和总磷均能在短时间达到城镇污水一级A排放标准,COD经小球藻培养系统处理虽达到一级A排放标准,但用时略长。每个污水处理周期可收获小球藻干物质0.43~0.47g/L进行资源化利用。研究结果表明本研究所选用的小球藻应用于城市污水处理产业的潜力巨大。In this study,the Chlorella zofingiensis was cultured in outdoor large flat plate photobioreactor in urban wastewater to investigate the urban wastewater treatment ability of chlorella zofingiensis under different seasons.The results showed that the effect of Chlorella zofingiensis in every season for denitrification and dephosphorization was significant,TN removal rate of 51.76%-97.66%,TP removal rate of79.37%-97.85%.TN and TP after treatment could achieve the discharge standard of urban wastewater A level in a short time,the removal of COD was slightly longer when it was treated by chlorella zofingiensis culture system.Each wastewater treatment cycle could be harvested about 0.43g/L-0.47g/L of dry matter of chlorella for resource utilization.These results indicated the chlorella strain used in this study has great potential to be applied to urban wastewater treatment industry.
