Рассмотрена возможность применения пивной дробины – основного отхода пивоваренного производства — для очистки сточных вод от нефти. Модификация серной и азотной кислотами при различных температурах повышает сорбционные свойства пивной дробины в отношении нефти. Увеличение концентрации кислот и температуры в процессе обработки пивной дробиной способствует снижению остаточной концентрации нефти в модельных растворах сточных вод, очищаемых модифицированной пивной дробиной. Установлено, что наибольшее удаление нефти из них происходит с помощью пивной дробины, модифицированной 5 %-ной серной кислотой при температуре 121 °С и избыточном давлении 1 атм. Использование модифицированной пивной дробины позволяет повысить степень очистки сточных вод, загрязненных нефтью.

The possible use of spent grain, main waste product of breweries, for purifying waste water from oil was considered. Modified sulphuric and nitric acids at various temperatures increase the sorption properties of spent grain with regard to oil. Increased acids' concentration and temperature during the treatment by spent grain help to reduce the residual concentration of oil in standardized test solutions of wastewater treated by modified spent grain. It was found that the maximal removal of oil occurs while using the spent grain modified by 5% sulfuric acid at 121 °C and overpressure of 1 atm. The use of modified spent grain makes possible to improve the purification degree of oil-contaminated wastewater.
