摘要
针对某制药业废水的特点,采用了“微电解-UBF-CASS”为主体的组合处理工艺。工程运行结果表明:在进水CODCr为10000￣12000mg/L,处理后出水CODCr小于200mg/L,平均去除率达到98%以上,系统出水达到《污水综合排放标准》(GB8978—1996)中的二级标准。
The process of micro-electrolysis-UBF-CASS was selected to treat pharmacy wastewater in the light of the characteristics of its wastewater quality.The operation results of this engineering project showed that the effluent could meet the requirement of class 2 of the National Intergated Wastewater Discharge Standard （GB8978-1996）.When the influent CODCr was 10 000 - 12 000 mg/L, the effluent CODCr, was less than 200 mg/L and the CODCr removal rate was over 98%.
