Organics and nitrogen removal from recycled landfill leachate using an aerobic process

One of the most popular types of bioreactor landfills is the landfill with leachate recirculation.In this way, an anaerobic was operated by leachate recirculation to remove organic matters. In this study two different systems were applied for leachate treatment. In system (1), the leachate generated from a fresh-waste reactor was drained to recirculation tank, and recycled every two days. In System (2), the leachate generated from a fresh waste landfill reactor was fed through a well-decomposed refuse landfill reactor, and at the same time, the leachate generated from a well-decomposed refuse landfill reactor recycled to a fresh waste landfill reactor.
