- The efficiency of enriched oxygen aeration is much higher than that in conventional oxygenic aeration, and there is an optimal aeration rate. 结果表明,富氧曝气的生物降解效能显著高于空气曝气,并且存在最佳的反应时间及气体用量。
- Theoxygen transfer rate increases with aeration rate and rotating speed,with the former parame-ter being the most significantly. 氧传递速率、通气速率均与转达有关,其中通气速丰的影响最为显著。
- The optimal fermentation has been obtained under the following conditions: carbon source(2.5% corn cob+2.5% wheat bran), nitrogen(0.2% tryton), inoculation level (four pieces of 0.25cm2), aeration rate (1/3 fermentation liquid volume ) and pH 6.0. 最佳碳源为2.;5%25玉米芯+2
- Abstract In this paper, a design method of loop seal typed recycle device used in CFB boiler is discussed in detail on the basis of structure parameters and air distributor of loop seal as well as external aeration rate and pressure. 针对流动密封阀结构尺寸,布风装置和外部充气量、充气压力的确定等方面,详细探讨了循环流化床锅炉中最常用的流动密封阀(LoopSeal)型返料装置的设计方法。
- When aeration rate is 3 vvm, the content of TUFA and DHA reach to peak. Generally, the content of DHA arrives at its peak in primary logarithmic-growth period, but TUFA does at steady growth period. 高的通气速率有利于TUFA及DHA含量的增加,当通气量为3vvm时TUFA和DHA的含量均达到最大,并且DHA的含量一般在对数生长初期即达到最大,而TUFA含量则在稳定期后才达到最大。
