Изобретение относитс к способам очистки сточных вод от грубодисперс- ных примесей и может быть использовано при очист ке сточных вод предпри тий цветной металлургии.The invention relates to methods of treating wastewater from coarse impurities and can be used in treating wastewater from non-ferrous metallurgy enterprises.
Цель изобретени - повышение степени очистки сточных вод от грубо- дисперсных примесей, содержащих медь.The purpose of the invention is to increase the degree of purification of wastewater from coarse dispersed impurities containing copper.
Пример, Сточные воды с рН 1-2 и с содержанием грубодисперсных при- месей 94,1 и 41,4 г/л обрабатывают раствором бутилксантогената кали до достижени различных его концентраций в сточных водах. После перемешивани сточные воды остаивают в тече- ние 3,5 ч и определ ют содержание грубодисперсных примесей в них и со держание меди в кеке.Example: Wastewater with a pH of 1-2 and with a content of coarse impurities 94.1 and 41.4 g / l is treated with a solution of potassium butyl xanthate to achieve various concentrations in the wastewater. After mixing, the wastewater is left for 3.5 hours and the content of coarse impurities in them and the content of copper in the cake are determined.
Дл сравнени сточные воды того же состава без обработки квантогена- том кали о тстаивают в течение 12 ч, а затем провод т анализ на содержание грубодисперсных примесей в них и содержание меди в кеке.For comparison, the wastewater of the same composition without treatment with potassium quanto genate is set for 12 hours, and then the analysis for the content of coarse impurities in them and the content of copper in the cake is carried out.
Результаты опытов представлены в таблице.The results of the experiments are presented in the table.
Из приведенных в таблице данныхFrom the data in the table
приводит к увеличению степени очист ки сточных вод от грубодисперсных примесей с 86-90 до 98-99,4%.leads to an increase in the degree of purification of wastewater from coarse impurities from 86-90 to 98-99.4%.
