The object of research is modern methods of wastewater treatment in the food industry. The purpose of the work is to develop proposals for the use of the best available technologies for the treatment of highly concentrated wastewater food industry in order to prevent negative consequences from their pollution of the aquatic environment. Research methods are experimental and analytical. As a result of research, proposals have been developed to improve the effectiveness of wastewater treatment in food production containing high concentrations of animal proteins, fats (including dairy production), hydrocarbons, ammonium nitrogen and phosphates and pose a danger to aquatic ecosystems when discharged into surface water bodies. Based on the analysis of domestic and world scientific and technical literature regarding existing wastewater treatment methods and our own experimental research, we proposed effective modern economically viable methods of neutralization of wastewater and developed basic technological schemes for purification of wastewater from food production. It was found that combining the physicochemical method of wastewater treatment with deep cleaning is achieved by biosorption treatment and the AOPs method wastewater to indicators that meet regulatory requirements, installed for discharge into a surface water body or municipal treatment facilities or use for the technical needs of enterprises. COD up to 98%, as well as the disinfection of wastewater from bacteria of the Escherichia coli group and other pathogens microorganisms.
