Abstract

The article discusses the optimization of parameters of environmentally friendly technologies in the processing of liquid waste in order to obtain organic fertilizer and liquid phase for irrigation and increase the fertility of agricultural land. These parameters are established on the basis of studies of the processes of reagent fractionation of highly concentrated biogenic elements of liquid waste from pig farms. The regression equations were used for the experimental data obtained by studying the influence of the doses of ammophos suspension on the process of separation of liquid waste, the settling time in sedimentation tanks, and also the initial temperature of liquid waste. An optimization model of the reagent process has been created, which allows, depending on the volume of treated waste, to determine the ratio of reagent doses and settling time.
