Abstract: In the existing solvent recovery system of water suspension granulation process,the organic solvent steam is condensed by tap water,which exhibits low recovery rate.The solvent recovery rate can be improved from 60% to 90% when tap water and freezing liquid together are used to cool down organic solvent steam and a secondary condenser is installed in the outlet of organic solvent collecting tank.The circulation flow of tap water between water-ring vacuum pump and water tank is realized through using circulated tap water to absorb heat generated in the vacuum pumping process.After process optimization,the average COD in the inlet of wastewater treatment station decreases from previous 1 989 mg·L-1 to 534 mg·L-1 and the drainage after treatment can meet the comprehensive discharge standards for wastewater.
