Description
Изобретение относится к способам очистки сточных вод от цианидов ц может быть использовано в химической, металлургической и других отраслях промышленности.The invention relates to methods for wastewater treatment from cyanides c can be used in chemical, metallurgical and other industries.
Целью изобретения является повышение степени очистки и сокращение времени процесса.The aim of the invention is to increase the degree of purification and reduce the time of the process.
Прим ер 1. Сточную воду с содержанием цианидов 100 мг/л обрабатывают сульфатом двухвалентного железа в количестве 1,47 г/л. После перемешивания в течение 2-х ч вводят известковое молоко до-pH 10, осадок отделяют и определяют концентрацию цианидов. Концентрация цианидов составляет 2,6 мг/л.Example 1. Wastewater with a cyanide content of 100 mg / L is treated with ferrous sulfate in an amount of 1.47 g / L. After stirring for 2 hours, milk of lime is added to a pH of 10, the precipitate is separated and the concentration of cyanides is determined. The concentration of cyanides is 2.6 mg / L.
Пример 2. В сточную воду с содержанием цианидов 100 мг/л вводят карбонат натрия или калия или аммония, обрабатывают сульфатом двухвалентного железа в количестве 1,05 г/л. После перемешивания в те- 25 чение 10 мин определяют концентрацию цианидов. Результаты опытов представлены в табл. 1.Example 2. In the wastewater with a cyanide content of 100 mg / l, sodium or potassium or ammonium carbonate is introduced, treated with ferrous sulfate in an amount of 1.05 g / l. After stirring for 25 minutes, the cyanide concentration is determined. The results of the experiments are presented in table. 1.
Пример 3. Аналогичен приме . ру 2, но карбонат (натрия) вводят в количестве от 0,4 до 6,1 г/л.Example 3. Similar to example. ru 2, but carbonate (sodium) is administered in an amount of from 0.4 to 6.1 g / l.
Из данных табл. 2 следует, что введение карбоната фактически в любых количествах позволяет получить эффект по очистке воды от цианидов.From the data table. 2 it follows that the introduction of carbonate in virtually any quantities allows you to get the effect of purifying water from cyanides.
