摘　　要：在相同试验条件下,采用间歇式非稳态曝气法进行清水充氧性能研究,通过测定氧的总转移系数、氧的转移速率、充氧能力、氧的利用率和充氧动力效率5项指标来考察弹性塑料填料、竹丝填料和竹球填料3种不同填料对反应器充氧能力的影响。试验结果表明:与弹性塑料填料相比,竹制填料在对反应器充氧性能的影响方面占有优势,可替代传统的塑料类填料作为生物接触氧化工艺的载体填料。Water oxygenation performance experiment was performed using intermittent unsteady aeration method under constant conditions. The influence of three different fillers, elastic plastic filler, bamboo filament filler and hollow-sphere bamboo filler, on the reactor＇ s oxygenation ability was investigated through five indicators, total oxygen transfer coefficient, oxygen transfer rate, aerobic capacity, oxygen utilization and oxygenated dynamic efficiency. Compared with the elastic plastic filler, the bamboo filler could replace the traditional plastic filler as the carrier of biological contact oxidation process because of its advantage in the reactor oxygenation performance.
