| 摘 要： | 采用沸石改性天然黏土以增强其对污染物的衰减能力,研究了沸石含量变化对黏土防渗性能的影响。试验结果表明:复合土的渗透系数都达到10-8cm/s;对COD、铵和硝酸根等污染物的去除率有明显提高;含5.66%沸石为最佳配比。用改性复合土作为垃圾填埋场衬里是可行的。

| Abstract: | In order to enhance the attenuation ability of natural clay for pollutants, zeolites were used as denaturant to modify natural clay.Influences of the zeolites percentage on natural clay's performance were studied. Experimental results indicated that the permeability of the compound soil was up to 10~(-8)cm/s; the attenuation efficiencies of COD, ammonia ion and nitrate increased obviously; the compound soil which contained 5.66% zeolite was the best one. It is feasible that the modified natural clay was used as liner material. |
