Abstract: The presented work presents the results of a chemical analysis of the discharged domestic wastewater of the Starobeshevskaya thermal power plant and the state unitary enterprise of the Donetsk People’s Republic «Energy of Donbass» for the content of suspended solids, ammonium nitrogen, nitrates, nitrites and phosphates for the period 2019–2020. The quantitative and qualitative changes in the composition of discharges before and after the passage of treatment systems are revealed, the insufficient efficiency of existing systems for complete biological treatment of domestic wastewater is shown, which requires the introduction of new technological solutions aimed primarily at cleaning from nitrogen and phosphorus compounds. Recommendations are given regarding the introduction of the technology of biological wastewater treatment using anammox bacteria. As measures for dephosphorization, the use of a reagent method for removing phosphorus by coagulation is recommended. The main advantages and disadvantages of the technologies proposed for implementation, recommendations are given regarding the hardware of the proposed technical solutions.
Keywords: waste water, biological treatment, nitrification, concentration, thermal power plant, anammox process.
