Research on the disinfection of livestock wastes by ultrasound

Abstract

Issues of using existing systems for the disposal, treatment and disposal of livestock wastes, taking into account environmental protection and improving the sanitary condition of livestock farms, need to be addressed immediately. The proposed technology for disinfection of livestock waste is cost-effective only under certain conditions of processing of feedstock. Providing these conditions leads to higher cost of processing. The most advanced methods of disinfecting wastewater are physical methods of exposure. The use of ultrasound is effective in disinfecting livestock waste from aerobic and anaerobic bacteria. Destruction of pathogenic microflora occurs under the influence of alternating loads, the range of which is established by the proposed method. Theoretical studies have established the scope of wave processes corresponding to ultrasonic disinfection of livestock waste. Under certain modes of radiation intensity and frequency, ultrasound results in a decrease in the coli titer of E. coli and staphylococci.
