Abstract

Abstract

Landfill is one of the main anthropogenic emission sources of greenhouse gases. Due to historical reasons, there are a large number of expired landfills and informal storage yards in China facing a severe problem of waste stock that needs to repair urgently. Aerobic remediation technology has been widely used because it can effectively accelerate waste stabilization, but its carbon emission characteristics in the remediation process are still not clear. Taking a large-scale landfill as the object, this paper investigated the change characteristics of landfill organic waste and secondary pollutants under different repairing states, revealed its stabilization process under aerobic repair, and calculated the effect of methane emission reduction in this process. The results showed that under the aeration and water injection of 322.34 m³/min and 25.65 m³/d respectively, by intermittent gas injection method (opening for 3 hours and stopping for 3 hours, running for 9 hours per day), the content of organic matter in garbage decreased from 47.66% to 17.86%; the proportion of methane in landfill gas decreased from 0.02%~46.48% to 4.23%, reaching the requirement that the methane concentration at the outlet of air duct was less than 5%; the concentrations of COD, ammonia nitrogen and total nitrogen in leachate decreased to 800.8 mg/L, 680.9 mg/L and 897.8 mg/L respectively; during the restoration process, the actual methane emission of the landfill was reduced from 24.57 tons to 2.47 tons, cut by 22.10 tons. At the same time, due to the acceleration of the stabilization of the landfill, its methane emission potential was reduced by 1.75 kg/t waste. In conclusion, aerobic remediation could provide important support for methane emission reduction in landfill sites.
