在农业化肥污染日益严重的今天,探讨污染物在地下水中的运移规律,提出合理的预测和治理污染的方法,是我们目前急需解决的问题之一。本文在实验的基础上,对NH4+在砂土与黄土中运移规律进行探讨与研究,以期对预测和控制N在砂土与黄土中污染治理能有所意义。
Nowadays, with the aggravating pollution of agricultural chemical fertilizers, it is one of the problems we urgently need to solve nowadays to discuss the transport of pollutants in groundwater and to put forward the reasonable methods of forecasting and controlling pollution. On the basis of experiments, this paper discusses and studies the NH4 + transport in sand and loess so as to be of significance in predicting and controlling N pollution in sand and loess.
