Abstract

Abstract. Municipal waste landfill leachate is formed at different stages of landfill operation and has a negative impact on a natural environment. According to the recently implemented waste management policy, landfill leachate in modern solid waste disposal sites has been monitored. Due to a complex composition of components for filtrate, over a long period of time, the processes of commutation in a drainable layer have been taking place, thereby reducing the porosity and permeability of the layer. Calcium, silicon and iron compounds are the main elements influencing a decrease in conductivity. Filtrate has formed in landfills and waste water and involved the process of precipitation percolating through waste. For 3 months, studies on two different drainage layers of filtration have been carried out. The obtained results have showed that for forming the landfill leachate drainage layer, a drainage rubble layer of 40% mixed with counter rubber waste can be successfully used.
