Most landfills dont meet the requirements for the terms of waste disposal and are just dumps without any engineering infrastructure protecting biosphere objects from polluting. Chemical and microbiological processes occurring in the municipal solidwaste mass lead to the formation of harmful substances polluting water objects.
The designs of landfills MSW should have a two-stage scheme of wastewater treatment. The first stage of treatment is done in ponds-regulators of high capacity by homogenisation, dilution and long-lasting settling of wastewater. The second stage of treatment is performed on plants of physical-chemical and biological treatment. Negative influence of the rest harmful substancesdecreases if there is a big enough natural biochemical barrier between the water wall and the nearest water-bearing level, i.e. if the basement of the landfill has rocks that can effectively prevent pollutants taking out to ground water levels.
