Abstract
Способ утилизации отработанных травильных растворов, содержащих сульфаты и хлориды железа (II), окислением катионов железа (II) с применением окислителя и целевым использованием переработанных растворов, отличающийся тем, что в качестве окислителя применяют концентрат гипохлорита натрия, а переработанные растворы используют как коагулянты в процессах водоочистки. The method of disposal of spent pickling solutions containing iron (II) sulfates and chlorides, the oxidation of iron (II) cations using an oxidizing agent and the targeted use of recycled solutions, characterized in that sodium hypochlorite concentrate is used as an oxidizing agent, and the processed solutions are used as coagulants in the processes water treatment.
