采用产朊假丝酵母预处理和DCD-HCHO絮凝剂再处理的联合工艺处理皂素废水。通过单因素试验和正交试验来分析和确定联合工艺的最佳处理条件。结果表明：1）产朊假丝酵母法预处理的最适条件为温度25℃、pH5.5、接种率10%、发酵时间3 d；2）DCD-HCHO絮凝剂法再处理的最适条件为pH值7/DCD-HCHO投加量4 mL/L、搅拌时间3 min；3)在联合工艺的最佳处理条件下，废水的COD总去除率和色度总去除率分别为94.61%、96.87%，出水的COD及色度均能达到《皂素工业水污染物排放标准》(GB 20425-2006)的排放要求。

A combined process technique for sapogenin wastewater was carried out here, in which sapogenin wastewater was pretreated by Candida utilis and retreated by DCD-HCHO. The effect of the treatment and the impact factors were discussed by single factor experiments and orthogonal optimizing experiments. The main conclusions were as follows： 1） The results of the Candida utilis pretreatment indicated that the optimum temperature, pH and inoculation method were 25 ℃, pH 5.5 and inoculated at a ratio of 1 ： 10 respectively; 2） The results of the D...
