Документ Wastewater treatment from nitrogen compounds(2020) Semenova, Olena; Bublienko, Natalia; Suleyko, Tetiana; Reshetnyak, LyudmilaIncreasing the concentration of nitrogen compounds in wastewater has led to a deterioration of surface water quality, which is the main source of economic drinking water supply for the vast majority of Ukrainians. The Government of reservoirs in the territory of Ukraine recorded an excess of norms for ammonia nitrogen – 2 – 15 times, nitrates – 7 – 20 times. The consequences of contamination with nitrogen compounds are eutrophication, which is caused by hypertrophied development of algae («flowering»); reducing oxygen content. We have proposed biological sewage treatment with this type of contamination.Документ Method of mathematical planning of experiment for optimal flowsheet selection of biochemical oil wasterwater treatment(2013) Semenova, Olena; Smirnova, Elizabeth; Bublienko, Natalia; Shylofost, Tatiana; Bublienko, AlexandrTo cleanse oily wastewater by us was used combined scheme, which includes removal of contaminants in foam layers for gas-liquid countercurrent oxidation and activated sludge pollution in the full oxidation. Done mathematical experiment planning to select the optimal scheme biochemical purification. Experimental research of biochemical treatment of oily wastewaterДокумент Intensification of biochemical purification of oil wastewater process by acting on biocenosis activity(2012) Semenova, Olena; Bublienko, Natalia; Smirnova, Elizabeth; Shylofost, Tatiana; Pastushenko, A.Questions intensification of biochemical sewage treatment using yeast autolysate. Studied the stimulatory effect of yeast autolysate on the kinetics of the purification process and the quality of sludge from the viewpoint of its utilization. Розглянуто питання інтенсифікації біохімічного очищення стічних вод за допомогою дріжджового автолізату. Вивчено стимулюючий вплив дріжджового автолізату на кінетику процесу очищення і на якість активного мулу з точки зору можливості його утилізації.Документ Purification of oil wastewater(2012) Semenova, Olena; Bublienko, Natalia; Smirnova, Elizabeth; Shylofost, TatianaThe given article discusses the problem of treatment of oil wastewater. It is known that the problem of oil wastewater treatment is topical nowadays, because as a result of various technical and technological processes the formed oil wastewater is not utilized properly. The article provides the information of pollution of oil waste¬water which is produced by the food enterprise, and also the ways of its purification. The objective of research is the intensification of the process of biochemical treat¬ment. Scientific novelty of the research lies in biosorbtion of oil gas-liquid counter-current mode and oxidation in an airtank-clarifier.
