“…These studies of the leachate composition, as well as the analysis of the results of other researchers' studies of landfill leachates (Dushkin et al, 2022, Haydin et al, 2013, showed that the leachate contains a high content of heavy metals, which is due to the presence of metal-containing substances capable of corroding at the landfill. Therefore, such infiltrates require a certain complex technology for their cleaning, since their composition is multi-component.…”

“…In the following works, the composition of leachates from different landfills of solid waste in Ukraine was analyzed, namely in Lviv (Haydin et (Stalinska, 2016), Mariupol (Mykhaylenko & Kapustin, 2013) and some others (Dushkin et al, 2022). As studies show, the concentration of pollutants in the leachates of solid waste landfills often exceeds the maximum permissible standards (MRLs) several times, which does not allow leachates to be discharged into water resources.…”

The characteristics of the hydrogeology of the municipal solid waste landfill in Ivano-Frankivsk are given. Accumulation of waste in landfills causes environmental problems due to pollution of the atmosphere, water resources, and soil. It was established that there is practically no contamination of the water horizon with infiltrate. Commissioning of the leachate pipeline, which feeds part of the leachate to the city's treatment facilities, solves the problem of the accumulation of leachate at the landfill, however, creates an additional burden on these facilities. The composition of the infiltrate was analyzed. It was confirmed that the main harmful pollutants of infiltrates are oil products, nitrogen-containing compounds, dyes, humic compounds, and heavy metals. The main methods of cleaning of infiltrates abroad and in Ukraine are characterized. Based on the analysis of the available impurities, for the purification of the infiltrate, it is proposed to use the technology of physical-electrochemical wastewater treatment, which includes their treatment in electrocoagulators and the separation of coagulated impurities in a thin-layer settling tank. Our studies showed that during infiltrate purification up to normative indicators of its discharge to treatment plants are not reached and it is worth using additional treatment of the infiltrate with oxidizers. As a result of exploratory studies, it is proposed to carry out additional treatment with hypochlorite ions, which can be obtained during the electrolysis of the infiltrate on an inert anode. Cleaning the infiltrate using the described technology will reduce environmental pollution, which means increasing the level of environmental safety of the solid waste landfill.

The article analyses the prerequisites for the formation of environmentally hazardous leachate generated during the life cycle of solid waste landfills, namely, during the decomposition of their organic component, in particular, including the stage of aceto- and methanogenesis. The article emphasises the multicomponent nature of the generated wastewater and the pollution's high level by such indicators as biological oxygen demand, chemical oxygen demand, suspended solids, and colour. This necessitates the use of multi-stage treatment technologies, including mechanical and biological treatment. The main goal of the article was to find out which ways and approaches able to improve of treatment efficiency, in particular using the mechanical treatment stage (pre-treatment). The colour and suspended solids content were chosen as control indicators, and the assessment of the dynamics of changes in these indicators and the level of their sensitivity to the coagulant's work's (use of aluminium sulphate as a coagulant) makes it possible to make conclusions about the effectiveness of the proposed method. In particular, the paper had been proposed the use of an activated solution of aluminium sulphate coagulant, the properties of which change and the efficiency increases under the action of magnetic-electric activation. This approach, as we are expecting is to intensify the leachate treatment process and reduce reagent consumption by 25-30% without the quality of treatment reducing, will allow to reduce the residual amount of aluminium in treated wastewater, to reduce the amount of sediment formed during the treatment of drainage wastewater, and to minimize the negative impact on the environment during the discharge of treated wastewater into surface sources. The selected optimal dose of the coagulant allows maintaining the required technological mode of operation of the treatment facilities in case of changes in the quality of wastewater entering the facilities. The use of aluminium sulphate as a coagulant was proposed, and the studies were carried out in in the following dose range 100-350 mg/dm3. Keywords: dose, coagulant, leachate, efficiency, assessment, suspended solids, colour, sludge, activation
