磁河有机污染物在饱和土壤中迁移转化试验研究

Experimental Study on Transport and Transformation of Organic Pollutants in Cihe Wastewater in Saturated Soil

    摘要
  • 摘要: 通过静态吸附、静态降解和动态土柱试验,研究了磁河废水中有机污染物在土壤饱水条件下的迁移转化行为.实验结果经线性拟合和参数估算,得到弥散系数D=0.0036m2/d,分配系数Kd=0.19cm3/g,降解系数K=0.68 d-1.表明磁河有机污染物在土壤中有较强的吸附和降解能力.

     

    Abstract: hrough experiments of static adsorption,static degradation and dynamic soil column,the transport and transformation of organic pollutants in wastewater in saturated soil were studied.Longitudinal dispersion coefficient(D=0.0036 m2/d),adsorption coefficient(Kd=0.19cm3/g)and biodegradation coefficient(K=0.68d-1)were obtained through curve fitting and parameter estimation.The results indicate that organic pollutants in wastewater are readily adsorbed and degraded in the soil.
