Исследованы закономерности электрохимического получения гидратов окиси двух- и трехвалентного железа, их свойства и эффективность применения в процессе электрокоагулирования для очистки сточных вод, содержащих стойкие органические загрязнители (СОЗ). Приведены результаты изучения области формирования гидратов окиси двух- и трехвалентного железа по показателю рН. Установлено влияние на электрохимическое получение ионов железа следующих факторов: удельное электрическое сопротивление воды; присутствие в воде СОЗ в виде поверхностно-активных вещества (ПАВ) анионного и неионогенного типов. Определены рекомендуемые значения технологических показателей элетрохимического коагулирования – удельный выход ионов железа, плотность анодного тока, степень извлечения СОЗ применительно к сточным водам красильно-отделочных производств предприятий легкой промышленности.

The regularities of electrochemical formation of ferrous and ferric hydroxide hydrates, their properties, and the efficiency of their application in the process of electrocoagulation for the treatment of wastewater containing persistent organic pollutants (POPs) were investigated. The results of studying the formation domains of ferrous and ferric hydroxide hydrates as a function of pH are presented. The influence of the following factors on the electrochemical generation of iron ions was established: specific electrical resistance of water, the presence of POPs in water in the form of anionic and nonionic surfactants. Recommended values of process parameters of electrochemical coagulation are determined-specific yield of iron ions, anodic current density, and degree of POP removal-with reference to wastewater from dyeing and finishing enterprises of the light industry.
