英文摘要In order to treat the typical waste (acidic wastewater) from the production process of titanium dioxide, a collaborative utilization process of wastewater and pyrolusite was studied, which recovered both Ti, Fe from the wastewater and saved the amount of sulfuric acid used in the leaching process of pyrolusite. Acidic titanium dioxide wastewater was used to react with phosphoric acid to prepare titanium phosphate, and the recovery of titanium reached 95%. After the extraction of titanium, a portion of ferrous sulfate heptahydrate was separated using the freezing crystallization method. Then the pyrolusite was leached with a leaching efficiency of 93% for manganese. Finally, the pH was neutralized to 4 using manganese carbonate. Fe2+ was oxidized to Fe3+ and separated by precipitation. Compared with the neutralization and concentration methods, although the process is longer, it has higher resource utilization, less pollution, simple operation and wide application prospect.
