Abstract
Leachate, a semi-solid excruciatingly concentrated waste stream is an unavoidable potential threat which attributes additional burden to the municipal solid waste (MSW) processing and disposal (P&D) facilities. Safe handling, proper treatment, and eco-friendly disposal of leachate posses a challenge due to the elevated concentration of several objectionable parameters. Ancillarilly, sanitary sewerage systems serve only a low percentage of the national population and in non-sewer areas, more than 80% of the black and grey water including human excreta and other fecal matter ends up in septic tanks. Therefore, the present study tried to produce a wholesome remedy jointly to the sanitation and leachate management issues using the biological treatment mechanism. Experimental studies have been carried out to treat the combined effluent of MSW leachate and domestic wastewater in different ratios using up-flow anaerobic sludge blanket reactor. The result revealed that the Chemical Oxygen Demand (COD) removal efficiencies using domestic wastewater and MSW leachate as a substrate were about 84 and 86%, respectively with Hydraulic Retention Time (HRT) of 12h. Whereas, the COD removal efficiency of the combined effluent of domestic wastewater and MSW leachate at various proportions (70:30, 60:40, 50:50, 40:60, 30:70) was about 90%.
