Abstract:

According to the characteristics of Chinese medicine production wastewater with high content of drug residues complex organic pollutants and low biodegradability, combined with the actual engineering experience and research results of similar wastewater treatment, a drum screen-iron carbon microelectrolysis-catalytic oxidation-A/O biochemical combined process was carried out. The operation results showed that the process had strong stability and good treatment effect. The COD_Cr and BOD₅ in the effluent of the system were 65-83 and 12-15 mg/L respectively and the effluent indexes met the requirements of Discharge Standard of Water Pollutants for Pharmaceutical Industry Chinese Traditional Medicine Category(GB 21906-2008).

Key words: traditional Chinese medicine wastewater, iron carbon microelectrolysis, catalytic oxidation, A/O

摘要：

针对中药生产废水药渣含量高、有机污染物成分复杂、可生化性低等特点，并结合处理类似废水实际工程经验和研究结果，设计采用滚筒筛网—铁碳微电解—催化氧化—A/O生化联合工艺进行处理。运行结果表明：该工艺稳定性强，处理效果好，系统出水COD_Cr、BOD₅分别为65~83、12~15 mg/L，出水达到《中药类制药工业水污染物排放标准》（GB 21906—2008）的要求。
