Abstract
This paper deals with the problems of effluent disinfection due to hydrodynamic cavitation caused by using the biogas technology. Effluent disinfection due to the acting hydrodynamic field makes it possible to destroy pathogenic microorganisms without using chemical reagents. The effect of the hydrodynamic field on microorganisms can be studied experimentally. Therefore, for experimental studies, a laboratory unit to create a cavitation field is developed. The paper presents the methods and results of experimental studies on the effluent disinfection in Venturi tube with the help of the cavitation field. The results of the experiment showed that for the E. coli bacteria group there is a threshold of sensitivity to cavitation action. The liquid flow rate at which the intensity of cavitation can destroy the microbial cell is shown. The dependence of effluent disinfection degree on cavitation regime parameters is established. The results of experimental research prove the efficiency of effluent disinfection in the cavitation field.
