Methodology for solving the problem of wastewater treatment of dairy processing enterprises

Abstract

In Russia, as well as all over the world, one of the most acute problems is the protection of natural water resources from sewage contamination of food, especially dairy processing enterprises. However, despite the fact that restrictions, fines and suspension of their activities have been established at the legislative level for exceeding the established standards for the discharge of pollutants into reservoirs, they continue to cause more and more significant harm to the environment. The main objective reason for this phenomenon should be attributed to the lack of an effective technology for cleaning complex in composition, with changing even during the day physico-chemical properties of effluents of milk processing enterprises. The purpose of the study was to develop the concept of deep processing of secondary dairy raw materials for subsequent use in industrial production. The paper presents an analysis of the basic structure of the modern technology of wastewater treatment of dairy processing enterprises at factory treatment facilities and suggests the basic principles of processing secondary dairy raw materials. The analysis of the presented data shows that modern methods of wastewater treatment used in most dairy plants do not meet the standards. Following the proposed principles will ensure favorable conditions for the release of lactose from secondary dairy raw materials at subsequent stages of its deep processing. One or another combination of these processes primarily depends on the cost of technologies and the equipment necessary for their implementation, the volume of raw materials, the required depth of its processing, as well as the market price of finished products.
