초록

In this study, as a study on bioreactor landfills, the effect of Food Waste Leachate (FWL) injection on the accelerationof waste biocompression was examined by performing settlement experimentation using lysimeters. In the experiment,liquid was injected into the waste through three conditions, i.e. injection of distilled water, leachate recirculation, andrecirculation of leachate mixed with FWL. Compared with two other liquid supplying conditions, analyses of the chemicaloxygen demand (COD) and pH value of leachate showed that the recirculation method of mixing leachate and FWL whichsupplies additional nutrients, i.e. the organic matter in FWL, increases microbiological activities that decompose the wasteand allows an optimal pH value for waste biodegradation. Analysis of waste settlement curves and the characteristics ofwaste settlement showed that the recirculation of leachate mixing FWL could accelerate the waste settlement as muchas 2.9 times and 2 times more than those of the distilled water injection and the leachate recirculation, respectively. Basedon the results of this study, the recirculation of leachate mixing FWL would help to stabilize the landfill early byaccelerating the waste settlement and to gain additional spaces in the landfill.
