摘　　要：采用自行设计的室内土柱实验装置模拟渭河渗滤系统,研究了含有硝态氮污染的河水以及苯胺污染的河水在渭河渗滤系统中的环境行为及净化机制,得出:河流渗滤系统对硝态氮污水有很大的净化作用,其净化机制主要是反硝化作用,对硝态氮的去除率达到100%;河流渗滤系统对硝态氮和苯胺共存的污水也有很大的净化能力,其净化机制主要是反硝化作用和生物降解作用,对硝态氮和苯胺的去除率均达到100%。最后定量研究了二者在河流渗滤系统中净化程度。A self-designed experimental instruments of laboratorial soil column was made to simulate the infiltration system of Weihe River. The environmental behavior and purification mechanism of river water with nitrate-nitrogen and aniline were studied. It is concluded that the river filtration system is contributive to the purification of nitrate-nitrogen wastewater, and the main purification mechanism is denitration, with a removal efficiency of 100%. Besides, the river filtration system is capable of treating wastewater with nitrate-nitrogen and aniline by denitration and biodegradat the removal efficiency can also reach 100%. Finally, the purification degree of nitrate-nitrogen and aniline ion, and by river infiltration system was studied quantitatively.
