| 摘 要： | 利用活性污泥法对制药有机废水进行有机物降解实验。确定了最佳工艺参数：污泥种子为污水处理厂取样的干污泥，加入适量无机盐类，最佳温度20—30％，培养周期为一周左右，按n（BOD）：n（N）：n（P）=100：5：1的比例投加氯化铵、磷酸氢二钠营养液，持续供给微生物氧气，控制pH值为6～7。结果表明：培养出来的活性污泥具有较好的生物活性，对于BOD浓度2000～4000mg／L的制药有机污水，总BOD去除率一般在90％以上。出水BOD达到排放标准的50-100mg,／L。

| Abstract: | The optimal conditions were investigated and the activity of the activated sludge was tested. Through studies on factors affecting cultivation, the optimal conditions were selected： sludge was cultivated with necessary inorganic salt at 20 - 30℃ for more than 7 days [ n（BOD） ： n（N） ： n（P） = 100： 5：1 ], the optimal pH value was 6 - 7. The results demonstrated that under the above - mentioned conditions, the activated showed a high bioactivity and could be used to treat pharmaceutical wastewater. When treating wastewater with BOD concentration of 2000 - 4000 mg/L, the BOD removed rate was more than 90%, could meet the BOD standard requirement which was 50 - 100mg/L. |
