Description
Изобретение относитс к способам очистки сточных вод от ионов меди и хрома и может быть использовано на предпри ти х цветной металлургии, машиностро ени и нефтеперерабатывающей промышленности .The invention relates to methods for the purification of waste water from copper and chromium ions and can be used in non-ferrous metallurgy, machine-building and the refining industry.
Цель изобретени - повышение скорости процесса при сохранении высокой степени очистки,The purpose of the invention is to increase the speed of the process while maintaining a high degree of purification,
В качестве реагента дл очистки используют отработаиный сульфидирован ный едкий натр, образующийс при сероочистке нефтепродуктов и.сжиженных нефт ных газов 20%--ным раствором ед- кого натра - реагент ОСЕЙ.As a reagent for purification, the used sulfide sodium hydroxide, formed during the desulfurization of petroleum products and liquefied petroleum gases with a 20% sodium hydroxide solution - OSEI reagent is used.
Реагент содержит, г/л:The reagent contains, g / l:
Меркаптаны иMercaptans and
щего завода с содержанием 880 мг/л меди и 1360 мг/л хрома. Сточные воды в количестве А5 м обрабатывают раствором железного купороса до полного перевода Сг в Сг , после чего ввод т 0,6 мас.% (0,27 м) реагента ОСЕЙ. Врем коагул ции осадка 23 мин. Осветленный раствор содержит 0,01 мг/л меди и 0,05 мг/л хрома.880 mg / l of copper and 1360 mg / l of chromium. Wastewater in the amount of A5 m is treated with a solution of iron sulphate until the complete conversion of Cr to Cr, after which 0.6 wt.% (0.27 m) of the OSEI reagent is introduced. Sludge coagulation time 23 min. The clarified solution contains 0.01 mg / l of copper and 0.05 mg / l of chromium.

Способ осуществл ют следуницим образом.The method is carried out in the following way.
Сточные воды обрабатывают раствором FeS04, после чего ввод т реагент ОСЕЙ в количестве 0,640,7%. Образующийс осадок отдел ют отстаиванием. В растворе определ ют содержание меди и хрома.The wastewater is treated with a solution of FeS04, after which the OSEI reagent is injected in an amount of 0.640.7%. The resulting precipitate is separated by settling. The solution determines the content of copper and chromium.
П р и м е р. Очистке подвергают сточные воды производства меднохромо вых катализаторов нефтеперерабатываюPRI me R. Purified waste water is produced by the production of copper-chromium catalysts in oil refineries.
