摘要
研究了影响鼓风曝气系统氧利用率Eo 和动力效率Ep 的因素 ,给出了Eo 和Ep 与诸影响因素间的定量关系式。在鼓风曝气系统中 ,恰当地选取曝气器的浸没深度h和所产生气泡直径db 的组合 ,既可使氧气利用率高 ,又可使动力消耗少。
Affecting factors for oxygen utilization rate E o and dynamic efficiency E p in blasting aeration system are studied in this paper.Quantitative relations of E o and E p are gained.It is pointed out by the first time that in blasting aeration system properly selecting depth h under water surface for aerators and diameters d b of bubbles made by aerators are able to make oxygen utilization rate high and power consumption low.It is important for designing blasting aeration and reducing energy consumption in wastewater treatment.
