包气带土体NO-3污染的微生态修复实验研究

Experimental study of microecological remediation of soils in the nitrate-contaminated aeration zone

摘要: 社会经济的发展和资源的利用产生了一系列环境问题,尤其是化肥的超量施用,已经危及包气带土体和地下水的质量安全。大量的氮素没有被农作物吸收,经微生物硝化作用后,以硝态氮的形式进入包气带土体,使包气带土体普遍受到氮素不同程度的污染。本文简述了包气带土体硝态氮污染的室内微生态修复、阻控技术和实验研究,探讨了今后应用的可行性。

Abstract: With the social and economic development and utilization of resources, a series of environmental problems arise. Especially, the overuse of chemical fertilizers for agricultural purposes has endangered the safety of soils in the aeration zone and groundwa
