Effect of sugar waste and surfactant waste on the degradation of anaerobic bioreactor landfill components

摘要

Anaerobic bioreactor landfills are the landfills with an increased moisture content inorder to achieve a better biodegradation. Many Bioreactor landfills accept outside liquid wastes to achieve a higher moisture content. But the effect of these wastes on the degradation of landfill components is not known.rnIn this study, the effect of sugar waste and surfactant waste on the degradation of landfill components was investigated. Sugar waste and surfactant waste in different concentrations were added to the combination of paper, cardboard, office paper and plastic with a total moisture content of 70%. The samples were incubated, sampled and analytical parameters analyzed. Sugar waste having a COD of 250,000 mg/L in a concentration of even 5% of the total weight was found inhibitive due to a drop in pH and accumulation of volatile fatty acids. Reactors with surfactant concentrations ranging from 50 mg/L to 500 mg/L showed that a higher concentration of 500 mg/L or above may be inhibitive in nature and the inhibition increases with increase in the concentration of surfactant.
