ABSTRACT: The goal of the study was to evaluate the stability of the natural-technical system of an SDW landfill through the development of an imitation model of an anaerobic bioreactor of the SDW landfill and computational simulation of the processes of formation, transportation and accumulation of contaminated leachate during the infiltration of the brines of liquid effluents for the purposes of geo-ecological substantiation of safe disposal of "tails" (non-utilizable highly concentrated liquid effluents) at the landfill. With the example of one of the SDW landfills of the Vladimir Region we came up with new solutions and obtained new data: 1) on the time during which the maximum increase of salt concentration in the drainage system leachate will be detected after the start of the concentrate infiltration into the landfill body; 2) on the limiting volumes (amounts) of non-utilizable liquid effluents disposal, which the landfill body can take; 3) on the forecasting conditions of salts accumulation in the landfill body and in the leachate.
