Abstract
Integrated Aerobic-Reagent Technology for the Pre-Treatment of Leachates from Municipal Solid Waste Landfills
Highlights
According to the report of the International Finance Corporation (World Bank Group) (Municipal Solid Waste in Ukraine, 2015), 11−13 million tons of municipal solid waste (MSW) are generated in Ukraine annually, and more than 90% are stored at landfills and dumps
The leachate of the Lviv MSW landfill was used for research
The microbiological analysis revealed the appearance in the leachate of a wide range of microbiological aerobic culture, which differs significantly from the culture of activated sludge of municipal wastewater treatment plants (WWTP)
Summary
According to the report of the International Finance Corporation (World Bank Group) (Municipal Solid Waste in Ukraine, 2015), 11−13 million tons of municipal solid waste (MSW) are generated in Ukraine annually, and more than 90% are stored at landfills and dumps. The total number of waste storage facilities is about 6700, and their total area is estimated as 10,000 hectares. On the basis of the average annual height of the precipitation layer of 500 mm/year and the values of the runoff coefficient of 0.05–0.1, overall about 2.5–5 million m3 of leachate are formed annually at these facilities. Due to the lack of organized collection and treatment of leachate at many landfills and dumps, highly toxic leachate leaks directly into soils, underground and surface water bodies, causing great damage to the environment
