Embodiment 1
[0046] A packing matrix for treating landfill leachate, the preparation process is as follows:
[0047] 1) Select ore with a moisture content of 20% that has been buried in the landfill for 5 to 15 years, and after removing stones with particles larger than 10mm, broken glass, rubber and plastic that has not been fully degraded, wooden sticks, paper, etc. The abundance of Pseudomonas, Sphingomonas, Comamonadaceae and Hyphomicrobiaceae in the mineralized garbage was as high as 12.73%, 12.29%, 8.82% and 6.40%.
[0048] 2) Choose an ellipsoid, with a particle size of 13mm and a bulk density of 1.5g / cm 3 , ceramsite with a porosity of 0.7;
[0049] 3) Mix the mineralized waste and ceramsite at a mass ratio of 1:7, soak and stir in the nitrifying bacteria culture medium for 150 seconds, and mix well; every two days, replace with fresh nitrifying bacteria culture medium and mix well. , complete the primary packing matrix; the abundances of Pseudoxanthomonas, Sphingomonas, Comamon...

[0054] A packing matrix for treating landfill leachate, the preparation process is as follows:
[0055] 1) Select the mine that has been buried in the landfill for 15 to 20 years, and after removing stones with particles larger than 10mm, broken glass, rubber and plastic that has not been fully degraded, wooden sticks, paper and other debris, the ore with a moisture content of 20% The abundance of Pseudomonas, Sphingomonas, Comamonadaceae and Hyphomicrobiaceae in the mineralized garbage was as high as 12.73%, 12.29%, 8.82% and 6.40%.
[0056] 2) Choose an ellipsoid shape with a particle size of 6mm and a bulk density of 0.9g / cm 3 , ceramsite with a porosity of 0.3;
[0057] 3) Mix the mineralized waste and ceramsite at a mass ratio of 1:3, soak and stir in the nitrifying bacteria culture medium for 90 seconds, and mix well; every two days, replace with fresh nitrifying bacteria culture medium and mix well. , complete the primary packing matrix; the abundances of Pseudoxanth...
Embodiment 3
[0062] A packing matrix for treating landfill leachate, the preparation process is as follows:
[0063] 1) Select ore that has been buried in the landfill for 25 to 40 years, and remove stones with particles larger than 10mm, broken glass, incompletely degraded rubber and plastic, wooden sticks, paper and other debris, and the ore with a moisture content of 30% The abundance of Pseudomonas, Sphingomonas, Comamonadaceae and Hyphomicrobiaceae in the mineralized garbage was as high as 12.73%, 12.29%, 8.82% and 6.40%.
[0064] 2) Choose an ellipsoid shape with a particle size of 10mm and a bulk density of 1.2g / cm 3 , ceramsite with a porosity of 0.5;
[0065] 3) Mix the mineralized waste and ceramsite at a mass ratio of 1:5, soak and stir in the nitrifying bacteria culture medium for 100 seconds, and mix well; every two days, replace with fresh nitrifying bacteria culture medium and mix well. , complete the primary packing matrix; the abundances of Pseudoxanthomonas, Sphingomon...
