中文摘要:

为了考察生物接触氧化法对供水原水的净化效果，以不同填料为基质构建了4组生物接触氧化池，开展野外现场试验。结果表明：组合填料、弹性填料、SDF阿科蔓和BDF阿科蔓4组生物接触氧化池对TP的平均去除率分别为59.4%、59.4%、44.7%和51.9%；对NH⁺₄—N的平均去除率分别为36.5%、33.4%、35.0%和36.6%；对TN的平均去除率分别为21.6%、18.8%、22.3%和18.0%；对COD_Mn的平均去除率分别为13.9%、13.7%、14.5%和13.4%；对TOC的平均去除率分别为10.7%、13.6%、13.4%和11.5%；对UVA₂₅₄的平均去除率分别为31.1%、34.0%、25.3%和26.2%；对UVA₄₁₀的平均去除率分别为54.2%、62.0%、47.2%和49.3%。综合而言，组合填料生物接触氧化池对原水氮、磷营养盐的净化效果最好，弹性填料生物接触氧化池对原水有机物的净化效果最好，其次是组合填料生物接触氧化池。

英文摘要:

In order to study the purification effect of biological contact oxidation process on source water, the paper took different fillers as matrix to construct four biological contact oxidation ponds and conducted field experiment.The result showed that the mean removal rates of TP of the four biological contact oxidation ponds such as combined medium (AM), elastic medium (EM), SDF AquaMats (SDFM) and BDF AquaMats (BDFM) are 59.4%, 59.4%, 44.7% and 51.9% respectively; the mean removal rates of NH⁺₄-N are 36.5%, 33.4%, 35.0% and 36.6% respectively; the mean removal rates of TN are 21.6%, 18.8%, 22.3% and 18.0% respectively. For organic matters, the mean removal rates of COD_Mn are 13.9%, 13.7%, 14.5% and 13.4% respectively; the mean removal rates of TOC are 10.7%, 13.6%, 13.4% and 11.5% respectively; the mean removal rates of UVA₂₅₄ are 31.1%, 34.0%, 25.3% and 26.2% respectively; the mean removal rates of UVA₄₁₀ are 54.2%, 62.0%, 47.2% and 49.3% respectively.Totally, the biological contact oxidation pond of combined medium has the best purification effect on nitrogen and phosphorus.The biological contact oxidation pond of elastic medium has the best purification effect on organic matter in raw water and followed by the biological contact oxidation pond of combined medium.
