BIO-DENITRIFICATION OF MSW LANDFILL LEACHATE USING RAW AND COMPOSTED GARDEN REFUSE: A COMPARATIVE ANALYSIS

摘要

In the eThekwini Municipality, leachate from the Mariannhill Landfill site is being nitrified in a Sequencing Batch Reactor and used as a dust suppressant. The concentration of nitrate in the discharged leachate may still present a potential threat to the environment and will not comply with the discharge limits once the landfill is closed, thus an ad-hoc denitrification treatment is required.
