This article presents a detailed analysis of the possibilities of applying various methods for landfill leachate treatment, including biological, physicochemical, membrane, and hybrid technologies. The study examines the main parameters and characteristics of landfill leachate, which is considered one of the most hazardous by-products of municipal solid waste disposal due to its complex chemical composition and high concentration of pollutants. Particular attention is paid to the variability of leachate composition depending on landfill operating conditions and external environmental factors.
Based on an extensive review of scientific literature and existing practical experience, the article identifies treatment methods that are currently available and potentially applicable in Ukraine. The effectiveness of these methods is analyzed using real examples of leachate and wastewater treatment processes. The advantages and disadvantages of each approach are presented, taking into account operational efficiency, technological complexity, environmental safety, and economic feasibility. In addition, the treatment methods are compared according to key indicators, including biological oxygen demand (BOD), chemical oxygen demand (COD), ammonium nitrogen concentration, heavy metal content, and the degree of organic pollutant removal.
The influence of landfill age on the composition and characteristics of leachate is also investigated, as this factor directly affects the selection and efficiency of treatment technologies. The article provides a classification of landfills according to their age and analyzes the processes of leachate formation at different stages of landfill operation. Special attention is given to the bacteriological characteristics of landfill leachate, including the presence of microorganisms, pathogens, fungi, and other microbial contaminants that may pose environmental and sanitary risks.
The environmental impact of untreated leachate and the potential risks to soil, groundwater, surface water, and human health are identified and discussed. Based on the conducted review and comparative analysis, it is concluded that hybrid treatment methods are the most promising solution, as they combine the advantages of individual technologies, ensure greater treatment efficiency, and provide more universal application under varying local conditions and treatment requirements.
