本文研究的主要目的是评估生物量在周期性反洗快速过滤器中积累的可能性。生物量的积累和保留是快速过滤器有效发挥生物过滤器功能并去除可生物降解有机物（BOM）所必需的。本研究的具体目标是调查细菌在过滤介质上的沉积情况，评估反洗过程中沉积细菌的去除情况，并确定定期反洗对生物过滤器中BOM去除的影响。实验跟踪了两种模式细菌——铜绿假单胞菌和肺炎克雷伯菌——在清洁的过滤介质（即玻璃珠和过滤砂）上的沉积，以及随后通过反洗去除的细菌。 对实验结果进行了讨论。包括35个参考文献、表格和图表。

The main goal of the research contained in this article was to evaluate the potential for biomass to accumulate in a periodically backwashed rapid filter. Accumulation and retention of biomass is required for a rapid filter to effectively function as a biofilter and remove biodegradable organic matter (BOM). The specific objectives of this research were to investigate the deposition of bacteria onto filter media, to evaluate the removal of deposited bacteria during backwashing, and to determine the effect of periodic backwashing on BOM removal in a biofilter. Experiments tracked the deposition of two model bacteria - Pseudomonas aeruginosa and Klebsiella pneumoniae - onto clean filter media (i.e., glass beads and filter sand) and the subsequent removal of the bacteria by backwashing. The results of the experiments are discussed. Includes 35 references, tables, figures.
