Abstract

Analysis of literature sources, devoted to the problem of the municipal solid waste treatment proved the necessity of their compaction. The paper contains the results of the experimental study of the compaction process of pre-dewatered  and packed the municipal solid waste by means of experiment planning by Box-Wilson method. Adequate regression models of the compression characteristics of the municipal solid waste in the waste disposal vehicle, taking into account their relative humidity have been obtained. The validity of the regression models was tested on the basis of Fisher’s variance ratio and the significance of the regression coefficients – by Students criterion. The suggested mathematical models can be used in the process of mathematical modeling of the  prepacked  and dewatered solid waste compaction in waste disposal vehicle and for the development of the technique of the engineering calculations  of the machines and mechanisms parameters used for compaction, as the component of scientific engineering fundamentals of the design of highly efficient actuating organs of the machines for the collection and primary processing of the solid waste. Response surfaces of the objective functions – compaction pressure, density and relative humidity of the completely compacted and dewatered solid waste and two-dimensional sections of the waste in the parametric planes of the impact have been constructed, this enables to illustrate the dependence of the objective functions on separate impact parameters.
