Abstract

Taking the effluent of secondary biological treatment in one pharmaceutical factory as the object of study, taking coagulation, ultrafiltration and reverse osmosis treatments as the core technologies of the water reuse pilot test, the application effects of treatment process were analyzed. The results showed that, the turbidity of the clarifier effluent was lower than 10 NTU, and the removal rate of COD was 15.7%~48.8%. Ultrafiltration system operated steadily, whose transmembrane pressure stabilized at 0.4~0.6 kg/cm2. The turbidity of water produced is stable, which was controlled around 0.17~0.28 NTU, and the removal rate was 85.79%~97.45%. The removal for COD was not very effective, and the overall removal rate was not higher than 60%. The reverse osmosis operated steadily under high water flux, and the desalination effect was gradually optimized. The application of the coagulation, ultrafiltration and reverse osmosis on pharmaceutical wastewater reuse project was effective. The effluent of reverse osmosis could be used in most advanced processes of pharmaceutical process
