| 摘 要： | 为了探讨粉砂、粉质粘土、粉土对垃圾渗滤液中NH4+-N的吸附作用,在室内做了吸附实验,实验结果表明,三种土样吸附NH4+-N的等温吸附曲线均符合Langmuir模式,且最大吸附量分别为粉砂1.3 034 ms/g,粉质粘土1.109 mg/g,粉土0.3 439 mS/S.不同土样吸附NH4+-N的能力差异较大,三种土样的吸附顺序为:粉砂>粉质粘土>粉土;三种土样的迟滞因子分别为粉砂27.939,粉质粘土21.782,粉土18.257,说明粉砂和粉质粘土的防污能力较粉土强.

| Abstract: | In order to find out adsorbing function of silt,silty clay and silt loam ordinal to NH4+-N of leachate.The absorbability test has been done indoor.The adsorbing of NH4+-N in silt,silty clay and silt loam measure up to Langmuir mode,and maximal adsorbability of silt,silty clay and silt loam ordinal are 1.303 4mg/g,1.109 mg/g,0.343 9mg/g.Adsorbability is difference about Various lithology,and sequence is silt>silty clay> silt loam.Hysteresis coefficient is 27.939,21.782,18.257 about silt,silty clay and silt l... |
