摘　　要：通过比较不同的污泥驯化方法研究了活性污泥法处理蒽醌废水的可行性。结果表明,常规的CODCr负荷提升法需要50d才可以驯化出活性污泥。在进水中添加1g/L葡萄糖可以快速提高污泥浓度,但是驯化出的污泥活性很低,不能满足废水的处理要求。最好的方法是添加1g/L葡萄糖和原废水交叉循环驯化法,第28天就可以驯化出高活性的污泥。在平均进水CODCr为1050mg/L、HRT为24h的条件下,COD去除率达到95.6%。Three acclimation methods for activated sludge treatment of lime pretreated anthraquinone wastewater were compared in the laboratory. Using the conventional acclimation method of increasing organic loading,a long 50-day acclimation was required to produce a highly activated sludge. Adding 1 g/L of glucose to the feed resulted in a rapid increase in VSS concentration; however, the resulting sludge was not active enough to produce an acceptable effluent. The best acclimation method, using a feed which was supplemented with 1 g/L of glucose for two days in a 7-day cycle, shortened the acclimation time to 28 days, Employing the sludge of the best acclimation method and with a 24-h HRT, the activated sludge treatment of a highly contaminated feed （CODCr= 1 050 mg/L） achieved 95. 6% reduction in CODCr.
