摘要
对东北制药总厂废水处理厂的二级出水采用混凝-超滤-反渗透膜工艺进行中试处理研究。试验结果表明:混凝工艺对浊度和COD的去除率分别在62.0%和22.3%以上;超滤工艺对浊度和COD的去除率分别在87.4%和54.5%以上;反渗透工艺产水脱盐率在97.6%以上。工艺出水满足循环用水水质指标,工艺运行稳定。
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 opera- tion was stable.
