| Abstract: | The treatment of PKT alkali peeling waste water is difficult because of its high pH and organic contents. In tins article, the feasibility and affecting factors of the recovery PTA from waste water by acid disjunction are researched. The result shows that it is possible to recover PTA with a purity of 99. 8% by proper process. The recovery rate is 83% . While the remove rate of CODcr is 82%. So we can treat sewage by changing pollutants into resources. |
