Using the chlorination method to produce titanium dioxide, approximately 6~8t of waste acid with a mass fraction of about 20% is generated per 1t of titanium dioxide produced.In order to address the issue of acid waste pollution and resource recycling, domestic and international scientists and researchers have developed and studied various governance processes and methods, such as rare metal extraction, concentration neutralization, membrane separation technology, and so on.This article analyzes the advantages and disadvantages of various processes and proposes the mechanical separation method to treat waste acid of titanium dioxide, which has certain reference significance for carrying out new research on acid waste treatment processes.
