| description | Introduction. The process of integrated wastewater treatment from nutrients and biogenic elements, especially from ammonia nitrogen and nitrogen compounds, is the main function in the operation of a wastewater treatment plant nowadays. Due to creating an aerobic and anoxic media in structures with suspended activated sludge, biochemical reactions of nitrification and denitrification are realized. To increase the efficiency of wastewater treatment from nitrogen compounds using suspended microflora, it is necessary to determine the influence of technological parameters - hydrogen ion concentration, dissolved oxygen level and oxidation-reduction potential (ORP) on the integrated biological wastewater treatment process.Materials and methods. Experiments aimed at solving the problems posed for each reaction were conducted in order to determine the influence of technological parameters on the rate of nitrification and denitrification in a biological contact reactor.Results. As a result of the experiment, the values of the specific rate of nitrification with the optimal pH value of the reactor were obtained. For the denitrification process, the ratio between the dissolved oxygen level, the ORP, and the specific denitrification rate are estimated.Conclusions. It was shown that the pH value, dissolved oxygen level and ORP play a significant part in the process of integrated wastewater treatment from nitrogen compounds. |
