| 摘 要： | 在静态条件下,研究了北京地区4种不同类型土壤对氨氮和有机物的吸附和降解效果,在室内进行了15℃和24℃情况下的静态吸附实验,以及室内静态降解实验.实验结果表明:氨氮在不同类型土壤中的吸附过程基本符合线性模式,有机物在不同类型土壤中的吸附过程基本符合指数模式,黏土和重粉质黏土试样对氨氮和有机物的吸附规律都是随着温度升高吸附量反而下降,氨氮和有机物在不同类型土壤中的降解过程符合一级动力学方程模式.

| Abstract: | Under static condition,the adsorption effect of ammonia nitrogen and organic matter on four kinds of soil in Beijing area was researched.The static adsorption and static degradation experiments were conducted indoors under two temperature condition.The experimental results indicate that adsorption course of ammonia nitrogen in different kinds of soil obeys to linear pattern,and the adsorption course of organic matter in different kinds of soil obeys to index pattern.In addition,the adsorption performance of... |
