采用两种表面结构不同的颗粒活性炭研究了吸附表面对生物膜剪切损失和积累的影响。用完全混合流反应器进行实验评价。BFAC模型被用来解释实验结果。结果表明，一个非常不规则的碳表面提供了更好的保护初始生物膜的生长和生物再生比球形介质更早开始。两种碳的初始生物膜损失率分别为0.0和0.2天-1，完全生长后两种碳的剪切损失率系数增加到0.6至1.2天-1。在生物膜快速生长和活性炭生物再生期间，生物膜损失率作为一个复杂的函数增加，不能用简单的一阶损失函数描述。/.水污染。控制美联储，60，362（1988）。
Effects of the attaching surface on biofilm shear loss and accumulation were investigated using two granular ac tivated carbons with very different surface structures. Experimental evaluations were performed with a completely-mixed flow reactor. The BFAC model was used to interpret the experimental results. Results showed that a very irregular carbon surface provided better protection for initial biofilm growth and an earlier start for bio regeneration than did the spherical medium. The initial biofilm loss rates for the 2 carbons were 0.0 and 0.2 day-1, respectively and the shear loss rate coefficients were increased to 0.6 to 1.2 day-1 for both carbons after complete growth. During a period of rapid biofilm growth and GAC bioregeneration, the biofilm loss rate increased as a complex function that could not be de scribed by a simple first-order loss function. /.
