Abstract
The invention discloses a preparation method and application of in-situ high-efficiency degradation carbon based material of VOCs in landfill based on waste regeneration, which comprises the following steps: air drying the agricultural and forestry wastes to a moisture content of 0.001 wt %˜20 wt %, and the agricultural and forestry wastes mainly include: straw, wheat straw, leaves, branches, weeds, crushing them to a particle size of 0-50 mm with a grinder, and then using urea or amide as modifier The nitrogen enriched biochar was prepared by mixing the crushed agricultural and forestry wastes with a mass ratio of 1:50-1:10; the nitrogen enriched biochar was prepared by retorting the nitrogen doped agricultural and forestry wastes at 300-600° C. for 20-60 min, and then cooling them rapidly; the nitrogen enriched biochar was mixed with the sewage sludge with a moisture content of 90-98 wt. % with a weight ratio of 20:1-10:1 to get the nitrogen enriched microorganism The degradation efficiency of TVOCs in landfill is 96.74%˜99.70%.
