摘要
为了考察曝气生物滤池中穿孔管曝气性能及风量等因素的影响,通过同一风机供给不同实际生物滤池单元、不同风机供给同一滤池单元,进行曝气充氧试验,分析充氧能力、氧转移效率、动力效率的变化。结果表明,对于同一滤池单元,大风量风机的充氧能力比小风量风机高,动力效率和氧转移效率比小风量风机低;同一风机对于大体积滤池单元的氧转移效率、动力效率比小体积滤池单元的高。
In order to investigate the aeration performance and influencing factors of the perforated pipe in bio-aeration-filtration（BAF）,the experiment of aeration was carried out by using the same air blower acted on the different actual biofilter chamber unit and the different air blower acted on the same biofilter chamber unit.The variety of oxygenation capacity,oxygen transfer efficiency and dynamic efficiency were analyzed.The results show that for the same biofilter chamber unit,the oxygenation capacity of the large air flow blower is higher than the small one,while oxygen transfer efficiency and dynamic efficiency are lower than the small air flow blower.For the same blower,the larger the filter chamber unit volume,the higher oxygen transfer efficiency and the blower dynamic efficiency are.
