• A PROTOTYPE EXPERIMENT ON TREATMENT OF LEACHATE FROM GABAGE-DUMPED LANDFILL

抄録

In order to optimize treatment of leachate from garbage-dumped landfill, a micro-bubble generation technique was applied to feed oxygen into an anoxic layer of the leachate reservoir. Although the impounded water was successfully aerated and dissolved oxygen recovered a great deal, nitrification of ammonia did not so extensively occurred. The limiting factor of nitrification was found to be biochemical reaction that were not activated so much due to insufficient amount of bacteria colonies under relatively low water temperature. Most of the oxygen demand in the leachate was caused by ammonia but not by organic compounds, which was a very different water quality feature from that in rivers and lakes. Additional finding was that chemical oxygen demand of the leachate was highly correlated with ammonia concentration as well as with electric conductivity.
