Leachate

We consider waste management and management as an area of ​​ecological safety. As a result of the study, the ecological aspects of this branch of activity were analyzed on the example of the operation of the operating MSW landfill in the city of Kremenchuk. The prospective direction of the field of waste management in the region, as well as the state of its financing, are taken into account. Such dangerous factors in the operation of the municipal landfill for the environment as: pollution of groundwater and open dumps of the landfill have been identified.

The main stages of the reclamation of solid waste landfills have been considered. The processes that limit ensuring the ecological safety of reclamation have been identified. In particular, three stages that may be hazardous for the environment have been highlighted: leachate treatment, preparation of soil or substrate for biological reclamation, and preparation of seeds and planting material. Leachate treatment by the aeration method in an aerated lagoon is recommended. The prospect of using such a process has been investigated in laboratory conditions.

Municipal Solid Waste Management (MSWM) is a new and fast-growing business area that is becoming widespread in Ukraine. The fire accident at Lviv city landfill "Hrybovychi" forced the local governments to initiate work on its closure and reclamation. The Environmental Impact Assessment (EIA) of the planned activity is the first mandatory step in this direction. The complex nature of EIA procedures requires a similarly integrated approach to identify hazards and develop a shared vision of existing risks.

This work is an attempt to analyze the theoretical and practical aspects of landfill leachate treatment and analyze the pros and cons of the most widespread methods leachate treatment and suggest the method of complex purification of high-concentration sewage waters from solid domestic wastes (SDW) for example of Hrybovychi municipal solid domestic waste.
