Satin I. Joint sludge utilization of waste water and biodecay fraction of municipal solid waste by aerobic composting

The thesis is devoted to the analysis of features of the aerobic composting of a biodegradable fraction of solid domestic waste and household-domestic waste, an organic fertilizer being obtained. Mathematical dependency of the influence of basic factors on composting was obtained experimentally. Laboratory and experimental-industrial experimentation resulted in fixing optimal parameters for composting which allow neutralizing biodegradable waste for a minimum period of time and getting an organic fertilizer. Study of a thermal field and humidity and pH changes made it possible to state the composting techniques. Techniques of the aerobic composting of a biodegradable fraction of solid domestic and household-domestic sewage sludge allow producing a qualitative organic fertilizer and due to this the techniques can be recommended for public utilities.
