Variation Characteristics of Leachate Quality in Aerobic Landfill

In this study, the aerobic landfill simulation experiments were carried out for about 31 weeks. In order to found leachate quality variation character, the temperature in the reactor, leachate (pH, CODcr, BOD₅, NH₄⁺-N) were continuously monitored. Based on the data of water quality changing under aerobic condition, the characteristics (CODcr, BOD₅, NH₄⁺-N) of leachate were determined. The degradation rate of CODcr, BOD₅ and NH₄⁺-N in the leachate attains 98.69%, 99.94% and 99.72%, respectively.
