Abstract (English):
Despite the transition of most boiler houses to gas fuel, fuel oil is still used as a reserve fuel for most large and medium thermal power plants. However, often for draining fuel oil from tank trucks and rail transport it is necessary to heat it up to reduce viscosity. Most often, heating is carried out with steam, which gradually condenses in fuel oil storage tanks. Therefore, the problem of disposal and purification of such oil-containing wastewater is relevant both for small boiler houses and for large volumes of wastewater from thermal power plants. In this regard, these studies consist, first of all, in the development of methods for cleaning fuel oil-containing wastewater generated in boiler houses of industrial enterprises. In addition, local treatment facilities will help solve the environmental problem of cleaning such wastewater. The purpose of the work was to consider wastewater treatment methods and develop a scheme of local installations for cleaning fuel oil-containing wastewater from boiler houses located directly on the territory of industrial enterprises. In solving the tasks, the methods of analyzing previously available results, comparison and experimental studies were used. The article presents data on the composition of fuel oil-containing wastewater, considers methods for cleaning these waters, and presents a technology for processing fuel oil-containing wastewater in a hydrocyclone-filter station. The results of the experiment showed that a GC-75 hydrocyclone should be used to clean wastewater from boiler house fuel oil storage tanks, which has a fairly high cleaning efficiency and high productivity. Based on the results obtained, it was concluded that the "pressure hydrocyclone-super-fast filter" cleaning scheme has proven its efficiency.
