| 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: | Through 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 =0 003 6 m 2/d),adsorption coefficient( K d=0 19 cm 3/g)and biodegradation coefficient( K =0 68 d -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. |
