摘要
为了提高传统SBR脱氮除磷效率,采用泥膜复合SBR工艺处理人工模拟生活污水,通过小试试验探讨了不同泥龄系统脱氮除磷能力的影响。结果表明:系统不仅对TN、TP表现出稳定良好的去除效率,出水TN、TP浓度符合《城镇污水处理厂污染物排放标准》(GB18918-2002)的一级A标准;而且提高了系统抗冲击负荷能力。
In order to improve the traditional SBR nitrogen phosphorus removal efficiency, the effects of different sludge age on nitrogen and phosphorus removal efficiency were studied through small tests with the artificial domestic sewage simulated by sludge and membrane compound SBR process. The results show that this system not only presents preferable and stable removal efficiencies for TN and TP, the effluent TN and TP can meet the first level A criteria specified in Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant （GB18918-2002）, but also improved the system＇ s capacity to resistance to impacts.
