Изобретение относитс к очистке сточных вод от органических примесей и может быть использовано в металлургической промышленности при флотационном обогащении руд. The invention relates to the treatment of wastewater from organic impurities and can be used in the metallurgical industry for the flotation of ores.
Цель изобретени - повышение степени очистки сточных вод от органических соединений.The purpose of the invention is to increase the degree of purification of wastewater from organic compounds.
Пример 1. Очистке подвергают сточную воду в количестве 10 л, содержащую 2-8 мп/л метилизобутилкарбинола (МИБК). Добавл ют 0,4 кг/м смеси гидроксидов кальци и магни при соотношении 10:3 и через полученную суспензию пропускают озоно-воздушную смесь со скоростью Юл/мин и при содержании озона 10 мг/л в те чение 30 мин. Степень очистки от МИБК 99,5-99,7%.Example 1. Purification is subjected to waste water in an amount of 10 liters, containing 2-8 mp / l methylisobutylcarbinol (MIBK). 0.4 kg / m of a mixture of calcium and magnesium hydroxides are added at a ratio of 10: 3, and the ozone-air mixture is passed through the resulting slurry at a flow rate of 10 r / min and at an ozone content of 10 mg / l for 30 minutes. The degree of purification from MIBK is 99.5-99.7%.
Пример 2. Очистке подвергают сточную воду, содержащую 1-5 мг/л азрофлота - дибутилдитиофосфатаExample 2. Purified subjected to waste water containing 1-5 mg / l of azroflot - dibutyldithiophosphate
натри , далее способ осуществл ют по примеру 1. Степень очистки от аэрофлота 98,0-99,6%.sodium, then the method is carried out as in example 1. The degree of purification from aeroflots is 98.0-99.6%.
Пример 3. Очистке подвергают сточную воду, содержащую 0,52 ,0 мг/л ксантог.ената кали , далее способ осуществл ют по примеру 1. Степень очистки от ксантогената 98,7100% .Example 3. Purification was subjected to waste water containing 0.52.0 mg / l potassium xanthogenate, then the method was carried out as in Example 1. The degree of purification from xanthate was 98.7100%.
Пример 4. Очистке подвергают сточную воду, содержащую 5,7 мг/л МИБК, 1,5 мл/г аэрофлота и 1,4 мг/л ксантогената кали . Далее способ осуществл ют по примеру 1. Степень очистки от МИБК 99, азрофлота 99,5%, от ксантогената 99,4%.Example 4. Purification is subjected to waste water containing 5.7 mg / l MIBK, 1.5 ml / g aeroflot and 1.4 mg / l potassium xanthate. Further, the method is carried out as in example 1. The degree of purification from MIBK 99, azroflot 99.5%, from xanthate 99.4%.
Пример 5. Дл сравнени провод т очистку по примеру 1, но с использованием различных гидроксидов щелочноземельных металлов, в разном количестве. Полученные результаты представлены в таблице.Example 5. For comparison, the purification of Example 1 was carried out, but using different alkaline earth metal hydroxides, in different amounts. The results obtained are presented in the table.
