Abstract
Изобретение относитс к обработке промышленных сточных вод и может быть использовано дл очистки сточных вод от ионов т желых металлов, в частности меди, никел . Цель изобрет ени - упрощение процесса при сохранении высокой степени очистки. Дл осуществлени способа сточные воды, содержащие медь и никель, обрабатывают смесью алкилсиликонатов натри или кали с 5%-ным известковым молоком при следующем соотношении компонентов, об.%: алкилсиликонат натри или кали 10-80The invention relates to the treatment of industrial wastewater and can be used for the purification of wastewater from heavy metal ions, in particular copper, and nickel. The purpose of the invention is to simplify the process while maintaining a high degree of purification. For carrying out the process, waste water containing copper and nickel is treated with a mixture of sodium or potassium alkyl silicates with 5% lime milk in the following ratio of components,% by volume: sodium or potassium alkyl silicate 10-80

Изобретение относитс к обработке промьшшенных сточных вод и может быть использовано дл очистки сточных вод от ионов т желых металлов, в частности меди, никел .The invention relates to the treatment of industrial wastewater and can be used to purify wastewater from heavy metal ions, in particular copper, and nickel.
Целью изобретени вл етс упрощение процесса очистки при сохранении высокой степени очистки.The aim of the invention is to simplify the cleaning process while maintaining a high degree of cleaning.
Пример. В реактор объемом 1 л подают сточную воду, содержащую, мг/л: Си 200, Ni 10 и при интенсивном перемешивании добавл ют реагент, состо щий из 10-80 об.% водного раствора алкилсиликоната натри , остальное - 5%-ное известковое молоко. После осаждени содержани ионов меди и никел - lO,01 мг/л.Example. Waste water containing mg / l: Cu 200, Ni 10 is fed to a 1 liter reactor and with vigorous stirring a reagent is added consisting of 10-80% by volume of an aqueous solution of sodium alkyl siliconate, the rest is 5% milk of lime . After precipitation of the content of copper and nickel ions - lO, 01 mg / l.
