| Popis: | The study aims to identify process patterns of tars and oils removal from phenolic wastewater by reagent flotation with bringing those components’ content to acceptable concentrations. For the first time established is the effect of Al2(SO4)3, AlCl3, FeSO4, Fe2(SO4)3, Al2(OH)5Cl and FeCl3 doses onto residual tar content in phenolic wastewater. Results obtained give the possibility to prevent air pollution resulting from the toxic substances emission at the wet quenching with water containing excessive oils and to increase the quality of wastewater biological treatment. It is shown experimentally that the most efficient are Fe2(SO4)3, FeCl3 and Al2(OH)5Cl at optimum concentrations of 50, 30 and 30 mg/dm3 respectively. The Al2(OH)5Cl can be recommended for implementation at industry on existing coking plants and municipal wastewater treatment plants to improve the environmental air and water resources condition in Ukraine. |
