Field‐scale monitoring test of aeration for enhancing biodegradation in an old landfill in China

The field-scale test of aeration to accelerate biodegradation of the waste was conducted, which was selected in an old landfill in Hubei province in China. The long-term monitoring was presented, lasted for 11 months, to estimate the degradation stability of the landfill. The monitoring parameters included the temperature, COD and BOD of leachate, gas concentration, water level, settlement, and cellulose/lignin. The results show that the waste degradation rate was increased under the aeration condition, while there was a trend of the stability in the whole waste body. The water level within the landfill was adjusted by discharge measurements, contributing to the buildup of the oxygen environment in landfill. The C/L could be used to assess the stability of the full-scale waste during the degradation process. But, there was obviously discrete by means of drilled sampling. The field-scale test was needed to provide the evidence for aeration engineering operation. © 2015 American Institute of Chemical Engineers Environ Prog, 2015
