| 摘 要： | 本研究通过对复合垂直流渗滤系统的模拟揭示了该系统非生物机制与生物机制对有机污染物、营养元素的降解效果。研究表明，系统对污水中污染物的去除是在非生物机制与生物机制协同作用下完成的。对污水中的有机污染物和氮的降解是以生物作用为主，非生物机制为辅；对磷的降解则以非生物机制为主，生物机制为辅。生物作用对有机污染物、氮的去除占80％左右，非生物作用对磷的去除占58％左右。系统中氮转化以硝化效果为主，反硝化效果比较弱。

| Abstract: | The system's non-biological and biological degradation mechanism for organic pollutants and nutrient elements was revealed through the simulation of integrated vertical flow infiltration system;it was shown that the pollutant removal by the system was filfulled under the synergetic action of non-biological and biological mechanism;biological action prevailed in degradation of organic pollutants and nitrogen in water with non biological mechanism as an auxiliary action,while non biological mechanism prevailed in phoshrous degradation with biological mechanism as auxilary.In the system,nitrification action prevailed in nitrogen conversion,while denitrification effect was weaker. |
