摘要
通过摸拟实验,研究了氮化物在土层中的迁移与转化作用。结果表明,土层对NH_4^+有很强的吸附作用,NH_4^+难以通过土层进入地下水中:NO_3^--N基本上不被土层吸附,能顺利通过土层进入地下水,故是地下水氮污染的主要形式。
Several kinds of simulation experiments have been studied thoroughly for migration and inversion of nitrogenous compounds in soil. The result showed that soil has strong adsorption to NH_4^+, and difficult to permeate into ground water directly. NO_3^- -N is hardly to be adsorbed, it has strong ability of migration in soil and be able to permeate into ground water through soil easily, so it is a major form of nitrogen polution in ground water.
