本研究的目的是评估不同类型的反洗和启动策略对过滤水质量的影响，尤其是在过滤器成熟期间。启动策略主要包括反洗后的延迟、启动前的过滤和缓慢启动，以及这些策略的各种组合。试验在加拿大魁北克的Pont Viau饮用水厂进行，该厂的总容量为12万m3/d。试验在四个过滤器上进行，标记为F10至F13，这是双介质（砂无烟煤）快速重力过滤器，设计用于以4 m/h至11 m/h的过滤速度运行。正常的反洗条件包括5分钟的空气冲刷，然后进行9分钟的冲洗- 用清水冲洗。反洗后，在恢复使用前，用2分钟的过滤器过滤废水。包括8个参考文献、表格、图表。

The objective of this study was to evaluate the effect of different types of backwashing and start-up strategies on the quality of filtered water, specifically during filter ripening. The start-up strategies consisted mainly of delay after backwash, filter to waste before start-up and slow start, and various combinations of these. The experiments took place in the Pont-Viau drinking water plant in Quebec, Canada, which has a total capacity of 120,000 m3/d. They were performed on four filters, labeled F10 to F13, which are dual-media (sand-anthracite) rapid gravity filters designed to operate at a filtration rate of between 4 m/h and 11 m/h. Normal backwash conditions consisted of a 5-minute air scour followed by a 9-minute water rinse. After backwashing, a 2-minute filter to waste precedes return to service.
