摘　　要：以传统卫生填埋柱R2为对照，通过往生物反应器填埋柱R1内加载可渗透反应介质层1和2进行模拟试验，主要探讨了填埋柱R1垃圾渗滤液COD、总氮、氨氮及总磷的变化趋势，探索一种新型的加载介质层垃圾填埋处理方法。试验结果表明，填埋20周后，R1柱COD浓度基本维持在40000～45000rng／L间，约为R2柱的20％-30％；第24周，R1柱总氮和氨氮分别为206．5mg／L和167．3mg／L，在16—24周内，R1总氮和氨氮分别约为R2的14．5％～17．5％和36．2％～43．6％；18周时，R1柱总磷达最大值1．704mg／L，至第24周降为0．673mg／L，整个实验过程R1柱总磷约为R2的0．15％～0．56％。Using traditional sanitary landfill R2 as a control, the simulative experiment of loading permeable reactive barrier 1 （PRB1） and permeable reactive barrier 2 （PRB2） on the anaerobic bioreactor landfill R1 demonstrated the change tendency of COD, TN, NH4-N and TP of leachate. Results indicated that the COD concentration of leachate in R1 was basically maintained between 40 000 -45 000 mg/L after 20 weeks of incubation, approximately 20% -30% of R2. At the 24th week, TN and NH4-N concentration of leachate in R1 were 206.5 mg/L and 167.3 mg/L, respectively, and during 16 and 24 weeks, TN and NH4 -N concentration of R1 were about 14.5% - 17.5% and 36.2% - 43.6% of R2, respectively. TP concentration of R1 reached a maximum （1. 704 mg/L） at the 18th week, and then decreased to 0. 673 mg/L at the 24th week. TP concentration of R1 was about 0. 15% -0.56% of R2 in entire experiment course.
