Study and Application on the Cross-linking Agent and the Wastewater Treatment in Investment Casting
The slurring ability of the waxpattems was improved effectively by coating the rosin solution as cross-liking agent.Organic wastewater containing high concentration of rosin and other organic compounds was treated using emulsion-breaking combined with fenton catalytic,a rate of COD removal was up to 90%,the outflow quality reached the discharge standards.Effects such as the amounts of H 2O 2?Fe 2+ added and pH on COD removal were discussed.
