FIELD: sewage treatment from heavy metals. SUBSTANCE: industrial sewage were treated for two stages: at first - the complete precipitation of ferric ions (Fe-III) and then partially cleared flow is subjected for treatment with humates up to the complete precipitation of vanadium ions. Method can be used for isolation of vanadium concentrates. Method provides the increase of relative vanadium concentration in the deposit formed. EFFECT: enhanced effectiveness of vanadium extraction.

Изобретение относится к очистке сточных вод от тяжелых металлов, в частности ванадия, и может быть использовано в металлургической и теплоэнергетической промышленности для выделения концентратов ванадия. Способ обеспечивает повышение относительной концентрации ванадия в образующемся осадке, и за счет этого повышается эффективность процесса извлечения ванадия из промстоков путем обработки стоков в две стадии: сначала полностью осаждают ионы железа III, а затем частично осветленный сток подвергают обработке гуматами для полного осаждения ионов ванадия.The invention relates to the treatment of wastewater from heavy metals, in particular vanadium, and can be used in the metallurgical and heat power industry for the separation of vanadium concentrates. The method provides an increase in the relative concentration of vanadium in the resulting precipitate, and thereby increases the efficiency of the process of extracting vanadium from industrial wastewater by treating the effluent in two stages: first, iron ions III are completely precipitated, and then the partially clarified effluent is subjected to humate treatment to completely precipitate vanadium ions.
