NITRIC ACID STRIPPING LIQUID TREATMENT SYSTEM

摘要

Provided is a nitric acid stripping liquid treatment system comprising a supply device (1), a reduced pressure distillation device (2), a neutralizing adjusting device (4), a filtering device, an acid treatment device (7) and an electrolysis device (8), wherein the filtering device comprises a filtrate separating device (11) and a filter cake separating device (6); the supply device (1), the reduced pressure distillation device (2), the neutralizing adjusting device (4), the filter cake separating device (6), the acid treatment device (7) and the electrolysis device (8) are in communication in sequence in a liquid flow direction; and the neutralizing adjusting device (4) is externally connected with the filtrate separating device (11) and an alkaline liquid adding device (5). The system is used for treating a nitric acid stripping liquid, and can recover nitric acid, copper etc., so as to avoid waste.
