Automatic Control System of Heterophase Waste Management Using Gas-Contact Technologies

The implementation of projects for the system of supply and distribution of air in waste management has shown the need to create a mathematical model that would describe in general terms the behavior of gas flows under natural aeration and forced aeration in heterophase media (arrays of different nature). This model would be a necessary addition to chemical kinetics models describing the process of biodegradation of organic matter. One of the criteria for this process is temperature and time characteristics, its relationship with the degree of oxidation of organic matter, accumulation of organic carbon, carbon dioxide content, etc. If we know the nature of temperature changes over time, it is possible in the first approximation to control the course of the process by adjusting the air supply, the intensity of mixing, the degree of moisture, the additional introduction of multifunctional additives, etc. The paper describes the automated waste management system using gas-contact technologies. Gas flow management requires consideration of a huge number of parameters, besides the ones listed above, as well as the creation of generalized criteria for assessing the state of the system. These parameters are classified into the following groups: mechanical (strength), water-filtration and air-filtration, temperature, as well as chemical and biological, and summarized in a multidimensional data file. However, not all of the parameters included in the listed groups are central to the creation of generalized criteria for the choice of technology. Therefore, the decision maker (DM) indicates which parameters are more important and which are not, that is, selects the levels (you can choose different ones each time depending on the situation). To make the right decision when assigning a level, there must be an adequate control algorithm. Based on this algorithm, the automated system should allow one to process a large amount of data and suggest a solution. Then the automated control system already calculates the weights of each parameter and then the control action is automatically carried out.
