APPLYING THE CAVITATION EFFECT DURING ANIMAL WASTEWATER TREATMENT

Abstract

Purpose: to analyze the advantages of cavitation disinfection of wastewater of various origins, including animal husbandry wastewater. Discussion. The problem of purification and utilization of livestock wastewater in Russia is quite acute, as well as the search for an alternative source of water for irrigating crops, one of the ways of solving these problems is the use of wastewater in irrigation. However, such a solution, in its turn, has its own difficulties associated with sanitary and hygienic requirements, large capital investments are needed to prepare wastewater for irrigation, the conventional treatment systems are large and complex. This arouses particular interest to the study of water disinfection by cavitation treatment. The analysis showed that the cavitation method has established itself as a reagent-free, economically and energetically beneficial water disinfection, which is used in many areas of activity. Conclusions: the cavitation method of purification and disinfection of various types of wastewater has clear advantages over existing methods. However, it requires further deeper and more detailed study of the disinfection process of wastewater from animal husbandry with the possibility of obtaining a purified and disinfected liquid, rich in organic substances, having a fertilizing value during irrigating crops.
