1.
Aiming at the possible environmental impacts during mine-fill with the coal gangues from Yanma mine,two dynamic leach experiments were designed under simulation conditions in laboratory for analyzing the control effects: one is to mix coal gangues with clay uniformly,another is to fill the coal gangues and clay into layers seperately.
针对演马矿煤矸石矿井填充可能造成的环境影响,在实验室环境中制定了两种动态淋溶控制实验,来模拟煤矸石矿井回填后的控制效果。
2.
The release and leaching characteristics of N, P and K from sewage sludge applied to red soil were studied by field experiment and indoor incubation as affected by type, application method and rates of sewage sludge.
通过野外和室内培养方法研究了不同污泥处理方法、污泥施用量和污泥施用方式在红壤条件下N、P的释放和垂直淋溶特性,主要结果如下:1、施用污泥土壤电导率、N、P、K各元素形态的含量和在剖面各层的累积量随着污泥施肥量的增加而增加,随着培养时间的增加而减小,而释放量却随污泥用量的增加而减小。
3.
A lot of industrial solid wastes are brought in karst mountain area every year,these industrial solid wastes arose the secondary water pollution because of rain leaching and the others reason while they are deposited in there,and the secondary water pollution influences surface and ground water environment.
中国岩溶山区每年都要产生大量的工业固体废弃物,这些工业固体废弃物在堆存过程中,主要由于降水的淋溶作用,引起了二次水污染现象,对地表地下水环境产生了很大影响。
5)  Eluviate [英][i'lu:vieit]  [美][ɪ'luvɪet]
淋溶
6)  Leaching [英][li:tʃ]  [美][litʃ]
淋溶
1.
The Leaching and Transformation of β-Sodium Glycerophosphate in Yellow-brown Earths;
外源有机磷在黄棕壤中的淋溶和转化特征
2.
Analysis of characteristics of leaching release of some substances in coal gangue;
煤矸石中某些物淋溶释放特点的实验分析
3.
Effect of leaching solution at different oH Values on indexes released from swine feces;

补充资料:化学淋溶
分子式:
CAS号:

性质:天然降水在下渗到地表风化壳或土壤的过程中,其所含的化学物质(主要有氧、二氧化碳、硝酸盐、硫酸盐和氯化物等)所发生的氧化、溶解和下渗的作用。易溶性盐类(如硝酸盐、氯化物)经淋溶会大量进入水中,下渗到土壤深层;难溶性盐(如钙、镁的碳酸盐)较难进入水中,且下渗距离小。研究化学淋溶作用,可了解化学物质在土壤、风化垂直方向上的迁移规律,如酸雨中含硫化合物对土壤污染的问题等。
