Landfill Leachate Treatment using Moving Bed Biofilm Reactor
Journal Title: International Journal of Civil, Structural, Environmental and Infrastructure Engineering Research and Development (IJCSEIERD) - Year 2019, Vol 9, Issue 5
Abstract
Landfill leachate is the result of rainfall which passes through the dumped waste, the pollutants in the landfill leachate may lead to the contamination of surface and groundwater resources. Sufficient treatment is required for leachate before the disposal. The concentration of high organic content like COD (Chemical Oxygen Demand), Nitrogen and Phosphorous content and settlement of sludge causes major damage to the environment. Hence, the biological treatment with a suspended growth process was carried out in a lab-scale reactor. The recent process, moving-bed biofilm reactor (MBBR) technology was adopted to treat the leachate. The initial characteristics of leachate were analyzed and observed as pH of 8.75, the turbidity of 450NTU, Total suspended solids of 3427 mg/L, BOD of 9121mg/L, COD of 4082 mg/L and ammonia nitrogen of 1529 mg/L. The reactor was filled with 25 liters of leachate and biochips were suspended at the upper surface of the leachate. The tank was continuously aerated and the biochips with attached growth were observed. The efficiency of treatment proved the low reduction of COD and less settlement of sludge.
