摘　　要：活性污泥中活性微生物量是表征污染物去除能力的重要指标。探索了荧光染色法直接检测活性细菌的原理和测定方法,结果表明,大肠杆菌、唾液链球菌和铜绿假单胞杆菌的活菌细胞浓度与荧光光强的线性相关度都超过0.95;在惰性颗粒物浓度为20 mg/L到60 mg/L的范围内,其对荧光光强的影响可通过线性关系修正;搅拌速度为1 000 r/min且搅拌10 min时前处理效果最好。Active biomass was an important index of pollutants removal ability.Principle and assay method of fluorescence assay on active bacteria was studied.The results showed that the linearly dependent coefficients between bacterial including Escherichia coli,Streptococcus saliarius and Pseudomonas aeruginosa and fluorescence intensities all exceeded 0.95.When the concentration of the inert particulate matter was ranged from 20 mg/L to60 mg/L,the impact of inert particulate matter on fluorescence assay can be linearity corrected.The effect of pretreatment was best when agitation rate was 1 000 r/min and agitation time was 10 minutes.
