    Biological treatment of leachate landfill filtrates
    (2022) Kononenko, P.; Krachunov, G.
    Actuality of the work. Existing landfills of Ukraine today turned into powerful sources of environmental danger. The problem is specifically hectic for Ukraine since there are many landfills from Municipal solid wastes (MSW) in Ukraine that have been in a need for closing for a long time already. Same problem exists in other countries. For solution of this problem it is suggested a two-stage purification for infiltrates on landfills in Ukraine and reduction of environmental danger from their accumulation (that is observed on the example of Hrybovytske landfill). Aim and tasks of the work. Aim of the work is to increase a level of environmental safety of hydrosphere with the help of two-stage purification of infiltrates from landfills in aerobic lagoons and municipal sewerage pollution control facilities (PCF). For achievement of the set aim the following tasks should be solved: -to conduct analysis of environmental danger sources of hydrosphere on the territory of Hrybovytske landfill; -to study process of biological purification of infiltrates in aerobic lagoon in static regime; -to set optimum conditions for biological purification of infiltrates in aerobic lagoon in dynamic regime; -to set technological peculiarities of implementing a stage of pretreatment of infiltrates on landfills in aerobic lagoon; -to set stability of parameters for tertiary treatment of infiltrates on municipal PCF; Scientific part of the work lays in: 1. Setting impact of parameters in implementation process (time of delay of infiltrates in aerobic lagoon, temperature, periodicity of it) on effectiveness of infiltrates` purification in aerobic lagoon that would give opportunity to optimize purification process. 2. Studied peculiarities of biocenosis development of aerobic lagoon that enabled to prognosticate a development of biological process of infiltrates` purification. Result of the work is: setting optimum conditions for implementation of two-stage technology of landfills infiltrates purification.
