| Summary: | Introduction. An advanced technique of the livestock waste disinfection is considered. The essence of the method is in the integral physicochemical action of the alternating magnetic field combined with a chemical agent. The inductor can implement this method. A residual number of the colony-forming units of total coliforms is selected as the most critical parameter characterizing the quality of the disinfection process of livestock effluents. It is proposed to use the mathematical experimental design theory to improve the efficiency of investigating the disinfection process of livestock waste. Its application implies a normal law of distribution of the value frequency of colony-forming units of total coliforms. Materials and Methods . In the course of this study, the following methods were used: direct and indirect instrumental measurement; micrographics; least quadrants, theoretical definition of the random distribution, and statistical data processing. Research Results . The hypothesis on a normal distribution law was tested by setting up an experiment at the stand with certain conditions. As a result of the conducted experiments, a sample of values consisting of 100 observations is obtained. Based on the aprior information analysis, a hypothesis on the normal distribution law of the value frequency of colony-forming units of total coliforms was adopted. Discussion and Conclusions. In the course of studying the distribution law of the value frequency of colony-forming units of total coliforms characterizing the quality of the disinfection process, the accepted critical value of the Pearson test was compared to the calculated one. Since the design value is less than the adopted critical one, the hypothesis on a normal distribution law is accepted.
