摘　　要：利用琼脂包埋微藻制成颗粒,设计柱状光连续处理反应器,探讨反应器系统对NH^+4-N、PO^3-4-P的去除效果,并进行实际废水处理效果评价。实验结果表明:在HRT=24 h,曝气500 mL·min^-1,室温条件下,系统稳定运行后对NH^+4-N、PO^3-4-P去除率达到97.35%、96.13%;在进行实际废水处理中,出水口流出液NH^+4-N、PO^3-4-P、COD平均浓度为0.82 mg·L^-1、0.24 mg·L^-1、74 mg·L^-1,NH^+4-N、PO^3-4-P达到《城镇污水处理厂污染物排放标准》(GB18918-1002)一级标准,COD达到二级标准。Microalgae was embedded into agar to make particles,and a columnar photo-continuous treatment reactor was designed.The removal effect of NH^+4-N and PO^3-4-P by the reactor system was discussed,and the actual wastewater treatment effect was evaluated.The experiment results showed that,in HRT=24 h,500 mL·min^-1 aeration,at room temperature,the removal efficiencies of NH^+4-N and PO^3-4-P reached 97.35%,96.13%respectively during stable operation of the system.In the real wastewater treatment,the average concentration of NH^+4-N,PO^3-4-P,COD in the effluent were 0.82 mg·L^-1,0.24 mg·L^-1,74 mg·L^-1,respectively.The NH^+4-N and PO^3-4-P reached the first-level standard of Pollutant Discharge Standards for Urban Wastewater Treatment Plants(GB18918-1002),and the COD reached the second-level standard.
