摘　　要：为了研究造纸废水活性污泥驯化培养过程中微型生物的指示作用,试验在采用FAS-Jet射流曝气氧化沟系统处理造纸废水的调试过程中进行。根据微生物的生理特性,通过控制进水的p H值和温度、曝气池内的溶解氧量、N和P的添加量等条件,驯化培养处理造纸废水的活性污泥,同时对驯化培养的不同时期内微型生物的演变规律与生化处理效果之间的相关性进行研究,总结出不同驯化培养阶段及运行出现异常时微型生物的优势种及生长特性。In order to research the indicative function of microorganism during the domestication and cultivation of activated sludge for papermaking wastewater, according to the physiological characteristic of microorganism, the ex- periment was conducted in the debugging of an improved oxidation ditch process using forced air supply jet aeration system by controlling pH, temperature, dissolved oxygen, addition of N and P etc. Meanwhile, the correlation be- tween evolution of microorganism in different periods and biochemical treatment effect was studied. Dominant spe- cies and characteristics of microorganism at different stages of domesticating and cultivating activated sludge and in the abnormal running period are obtained.
