摘　　要：采用间歇活性污泥法和呼吸计量法测定活性污泥数学模型中异养菌产率系数。研究结果表明,间歇活性污泥法测定结果受试验控制条件特别是污泥有机负荷的影响非常大,且试验周期比较长;人工配水条件下,呼吸计量法测定异氧菌产率系数(YH)在0.71以上,比活性污泥数学模型推荐值高,其结果与底物性质有关,该方法准确性高,重现性良好。To predict the behaviour of biological wastewater treatment plants using Activated Sludge Models, the parameters and wastewater composition must be provided. A batch method of activated sludge and a respirometric method were employed to estimate the heterotrophic yield. It was found that the results of batch method was affected by the experimental conditions, especially organic loading of the activated sludge. This method was time-consuming and couldn＇t give well reproductive reliable heterotrophic yield estimates. Under conditions of different synthetic wastewater, the heterotrophic yield estimated by respirometric method was over 0.71, higher than that recommended in ASMs. Respirometric method had comparatively high reliability and accuracy.
