摘要
提出一种序批式活性污泥反应器(SBR)与微藻反应器(PBR)串联的工艺,利用SBRPBR串联体系进行生活污水的深度脱氮除磷。试验结果表明,当SBR在模式B(厌氧程序120min;好氧程序170min;缺氧程序120min)下运行,PBR的水力停留时间为2d时,SBR-PBR串联体系能达到最优的工况,其出水中的化学需氧量(COD)、总磷(TP)、氨氮(NH_(3)-N)以及总氮(TN)均能满足《城镇污水处理厂污染物排放标准》(GB 18918-2002)一级A标准,且较稳定。
This paper proposed a sequencing batch reactor(SBR)and photobioreactor(PBR)series system to deeply remove nutrient from domestic sewage.The results show that when SBR work with mode B and the hydraulic retention time of PBR is 2 h,the series system can achieve the best performance.The COD,TP,NH_(3)-N and TN of the effluent can meet the class A of Discharge standard of pollutants for municpal wastewater treatment plant.Besides,the SBR-PBR series system can work stably in at least 10 days.The study proves the feasibility of the SBR-PBR series system.
