摘要 采用SBR工艺对校园生活污水进行试验研究,考察了系统对COD、TP、NH4+-N的去除效果。通过正交试验确定了最佳的运行工况为:瞬时进水,厌氧1 h,曝气3 h,沉淀1 h。在最佳工况下运行时,COD、TP、NH4+-N的去除率分别达到89.5%、85.7%、68.1%左右,且通过20 d稳定运行试验,处理效果一直保持良好,为校园生活污水的中水回用提供了重要的技术参数。 According to the characteristics of schoolyard sewage, sequencing batch reactor(SBR) was conducted and the optimum operation parameters were determined: instant water coming-in, anaerobic 1 h, aeration 3 h, sedimentation 1 h. The experimental results showed that under this optimum conditions, COD, NH^4+-N and TP could be effectively removed by the efficiencies about 89.5, 85.7 %, 68.1%, and the treatment efficiencies always keep well after the following 20 day's stable operation. These important parameters were provided for the reuse of schoolyard sewage.
