Підвищення екологічної безпеки стічних вод харчових виробництв озонуванням шляхом очищення (знезараження)

Abstract

The modern method of disinfection of bacteria of sewage of production of potato chips by ozonation, for reuse of sewage is considered. Vegetable juices, which are processed, enter the wastewater during washing with vegetables, as well as after - during cleaning, cutting and preparation for processing. This increases the BOD and COD of the wastewater in need of treatment. If water enters the sewer, the indicators of COD and BOD must comply with the established norms in drainage. Otherwise there is a situation when the decomposition of organic matter. Cleaning from impurities on city constructions is carried out with use of biological methods of cleaning, it is practically impossible to use in the territory of the operating industrial enterprise. The analysis of literature data and information on the ozonation method is considered. The studies were performed on model wastewater containing suspended solids, BOD (biological oxygen demand), COD (chemical oxygen demand) and OMC (total microbial count) in quantities that corresponded to the average content of these indicators in real wastewater in enterprises after washing vegetables for secondary The use of wastewater in production must not only be treated from suspended particles to a state of clear water, but also to provide for the possibility of undesirable microbiological processes as a result of biological decomposition of soluble organic substances. The consequences of pollution can be very diverse for human health disinfection of purified circulating water. And as a result of research found ozonation should be used to disinfect bacteria.
