摘要：
针对南方特有的低浓度生活污水,研究了在低曝气条件下,气水比、水力负荷、进水有机负荷、碳氮比、填料层高度等因素对曝气生物滤池容积负荷的影响。结果表明,在气水比为3～1,碳氮比为3～4,水力负荷为1.1m3/(m2·h)条件下,CODCr和氨氮的去除率分别为97.37%和82.28%,出水有机物和氨氮质量浓度分别为3.4mg/L和6.94mg/L。碳氮比对反应器CODCr容积负荷的影响较对氨氮容积负荷的影响更为明显;氨氮的去除率受水力负荷的变化影响较小。

Abstract:
The main objective of the experiments is to study the influence of gas to liquid ratio,hydraulic and influent organic loading,carbon and nitrogen mass ratio and the bed material height on the volumetric loading of BAF operated under lower aeration conditions. The results show that, when the gas to liquid ratio is 3～1,carbon and nitrogen mass ratio is 3～4 and the hydraulic loading is 1.1 m3/(m2·d), the CODCr and total ammonia nitrogen (NH3-N) reductions averaged 97.37% and 82.28% respectively. Carbon and nitrogen mass ratio has more effect on the CODCrvolumetric loading than on the NH3-N. The hydraulic loadings has less effect on NH3-N removal.
