Prospects for studying the chemical composition and microbiological landscape of wastewater of enterprises
Journal Title: Modern Innovations, Systems and Technologies - Year 2023, Vol 3, Issue 2
Abstract
The aim of the work was to monitor the qualitative composition of wastewater from enterprises in the city of Ufa. The study showed that the waste waters of some enterprises are polluted by the content of suspended solids, oil products, ammonium ions, COD. A significant correlation was found between COD and BOD, BOD and the content of phosphate ions, BOD and the content of ammonium ions, pH value and the content of ammonium ions. The ratio between the COD and BOD indicators allows one to judge the composition of wastewater and is a hint when choosing the most optimal treatment method. An insignificant difference between these parameters indicates the feasibility of using biological treatment, because the more organic matter, the higher the BOD. A significant excess of COD, compared with BOD, indicates a high content of persistent organic compounds that are difficult to biochemically interact, and in this case, it would be more correct to use physicochemical purification methods. Gram-negative conditionally pathogenic bacteria of the Enterobacteriaceae family – Escherichia coli, Klebsiella pneumoniae, Salmonella sp., Citrobacter sp., were isolated and identified in the samples, which are more effective and environmentally safe to fight with the ultraviolet disinfection method. The monitoring carried out can become a good support in the selection of the most optimal wastewater treatment method.
