Abstract

Abstract: This study introduced the combination, characteristics and research progress of partial nitritation-anammox. Partial nitritation-anammox process and traditional biological denitrification process were compared in nitrogen removal rate, energy consumption and carbon source. Although partial nitritation-anammox process doesn't require organic carbon, its energy consumption is higher than traditional biological denitrification process due to heating and aeration. The difference between nitrogen removal rate of partial nitritation-anammox and traditional biological denitrification process is not significant. Carbon to nitrogen ratio of wastewater needs to be considered when choosing denitrification process. Traditional biological denitrification process is more suitable for high carbon to nitrogen ratio, and combined process is more suitable for low carbon to nitrogen ratio.

摘要： 当前对于相变蓄热器性能的评价指标主要是蓄放热时间,比较单一,不能全面准确地评价蓄热器性能。本文设计了一种以赤藻糖醇作为相变材料的间接式蓄热器,并通过铜管外加双直肋的手段强化传热。在相变材料内部以及进出口设有热电偶,利用控制变量法,通过改变进口油温以及导热油流量来观测不同工况下蓄热器内部温度的变化以及进出口油温的变化,对不同工况下蓄热器的蓄热效率、放热稳定性进行了分析。为了对蓄热器的充放热性能作出更加全面的评价,对蓄热器进行了分析。结果表明:在流量不变的情况下,随着温度的升高,蓄热效率基本相同,放热稳定性基本一致, 效率增加;在温度不变的情况下,随着流量的增加,蓄热效率降低,放热稳定性减弱, 效率降低。
