Abstract

Abstract: A pilot-plant test research was carried out by the process of coagulation-ultrafiltration-reverse osmosis to treat secondary effluent in Northeast General Pharmaceutical Factory. The results indicated that the removal efficiencies of turbidity and COD during the process of coagulation were more than 62.0% and 22.3% respectively. The removal efficiencies of turbidity and COD during the process of ultrafiltration were more than 87.4% and 54.5% respectively. And the desalting ratio during the process of reverse osmosis was more than 97.6％. The experimental results showed that the effluent’s quality of the process were satisfied and excelled to the quality index of circulation water, and the process operation was stable.

Key words: secondary effluent, coagulation, ultrafiltration, reverse osmosis
