  • 摘要: 通过对复合垂直流渗滤系统中增加球型填料，利用生物强化提高系统对城市生活污水污染物去除能力的研究，优化了复合垂直流渗滤系统。并且通过研究，探索了系统非生物作用与生物作用对氮的降解机制。结果表明，通过生物强化系统生活污水中COD的去除率由原来的74.7%提高到85.3%；对NH3-N的去除率由原来的28.7%提高到52.9%；对TN的去除率从31.0%提高到41.7%；系统对TP的去除率由30.9%提高到49.3%。球形填料通过提高系统的硝化活性，增加对氨氮的降解转化效率，同时生物量的大小，也是影响氨氮的降解转化效率的重要因素。系统对污水中氮的降解是以生物作用为主，氮转化以硝化效果较强，反硝化效果比较弱。
    Abstract: The effects of contamination removal were researched to treat municipal wastewater by biodegradation enhanced with adding spherical fillings in integrated verticalflow infiltration system(IVIS).The IVIS technological parameters were optimized by experiments.The result showed that the removal rates of contamination in wastewater were increased by biodegradation enhancement,COD from 74.7% to 85.3%,NH3-N from 28.7% to 52.9%,TN from 31.0% to 41.7% and TP from 30.9% to 49.3% respectively.The degradation efficiency of NH3-N was increased with the increase of nitrification by adding more spherical fillings in IVIS.The quantity of microorganism is an important factor affecting degradation efficiency of NH3-N.The biodegradation is the main process compared with abiotic interception in removal of nitrogen in the system.Nitrogen transformation is mainly result of nitrification,and denitrification is relatively weak in IVIS.
