摘　　要：文章主要研究在序列间歇式活性污泥法(SBR)中活性污泥的培养驯化,以人工配制的污水作为营养液,通过控制温度(26℃左右)、pH(6.8～7.8)、溶解氧(2～6 mg/L)等试验条件来进行污泥的逐步培养驯化,主要探究在培养期间活性污泥浓度(主要测其MLSS)、对COD的去除效果、30分钟沉降比和活性污泥微生物相随培养时间变化而变化的规律。以及培养中出现的异常状况与解决方法。This paper studies the cultivation of activated sludge by sequencing batch reactor.Using artificial sewage as nutrient solution,gradual cultivation was realized by controlling temperature（26℃）,pH（6.8-7.8）,dissolved oxygen（2-6 mg/L）.The main focus of this study is to examine activated sludge concentration（mainly mixed liquor suspended solids（MLSS））,removal rate of chemical oxygen demand（COD）,30 min settling ratio and how cultivation time affects the microorganisms in the activated sludge.Abnormalities and solutions during the cultivation are also focuses of this study.
