摘要： 针对发酵制药废水二级生化出水的水质特点，在实验室水平下利用三维电解法对其进行了深度处理研究，通过单因素实验和正交实验考察了pH、电流密度、活性炭投加量及反应时间等因素对处理效果的影响。结果表明，三维电解的最佳反应条件：电解时间为40 min，电流密度为50 mA/cm²，pH为3，活性炭投加量为15 g/L。电解出水经活性污泥法处理后达到《发酵类制药工业水污染物排放标准》（GB 21903—2008）的排放要求。

Abstract: Based on the characteristics of water quality of the secondary biochemical effluent from pharmaceutical fermentation, three-dimension electrolytic technology has been used for the advanced wastewater treatment, under laboratory conditions. By single-factor and orthogonal tests, the effects of pH, current density, activated carbon dosage, reaction time, etc. on the treatment efficiency are investigated. The results show that the optimal reaction conditions of three-dimension electrolysis are as follows:electrolysis time is 40 min, current density 50 mA/cm², pH=3, and activated carbon dosage 15 g/L. After the electrolyzed effluent has been treated by activated sludge process, it can meet the requirements of the Discharge Standard of the Pollutants in Industrial Wastewater from Pharmaceutical Fermentation(GB 21903—2008).

Key words: wastewater from pharmaceutical fermentation, three-dimension electrolysis, advanced treatment, activated sludge process
