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.
