Документ Cleaning of sewageswith use of pinotenk(2016) Semenova, Olena; Bublienko, Natalia; Shylofost, Tatiana; Semenova, Alexandra; Reshetnyak, LyudmilaCharacterized sewage containing hydrocarbons. It is shown that their purification is a complex biological process. This is due to the peculiarities of dissolving contaminated components in water. The use of the biosorption process for wastewater treatment with such contaminations is proposed. The principle of work of a pinotek, its advantages, features of use is given. The indicators of wastewater pollution before and after cleaning are shown.Документ Stabilization of active sludge after wastewater treatment contaminated by petroleum products(2016) Semenova, Olena; Reshetnyak, Lyudmila; Bublienko, Natalia; Smirnova, Elizabeth; Shylofost, TatianaBiochemical purification of wastewater containing refined petroleum products takes place due to the oxidation of pollutants by active sludge organisms. As a result of this process the intense consumption of pollutants by active sludge and its growth occurs. Therefore, the possibility to use active sludge containing refined petroleum products after wastewater treatment requires its stabilization. Methods:I n this work the oxidation by a 30% hydrogenperoxide solution was studied for its use as a stabilizer. Chemical oxidizers, including hydrogen peroxide destroy organic polymers retaining free water thus promoting water release from the structure of sludge particles. On the other hand remains of fine structured oxidized biopolymers can lead to filter clogging, that is, reduce moisture exchange of sludge. Results: The experiment was carried out to find out the correlation between the doses of hydrogen peroxide andthe resistivity value of sludge filtration. Discussion: Stabilized active sludge can be used as a fuel for boiler rooms, which in its turn will reduce natural gas consumption for the enterprise needs.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 wastewater
