  • 摘要: 硝化菌的生长和衰减动力学特性决定了活性污泥系统的硝化能力。通过数学模型分析明确了硝化菌的衰减动力学特性,建立了基于硝化速率的衰减速率常数测定方法,并对方法的重现性进行了验证。经测定,上海市白龙港、曲阳和竹园第二污水处理厂活性污泥硝化菌衰减均符合一级动力学规律,20℃下衰减速率常数分别为0.175、0.176和0.176d-1。
    Abstract: The growth and decay kinetics of nitrifying biomass determine the nitrification capacity in activated sludge systems. The decay kinetics of nitrifying biomass was built by mathematical model analysis, and the determination method for decay rate constant was established based on ammonium uptake rate and repeatability validation. The decay kinetics of nitrifying biomass in Bailonggang Wastewater Treatment Plant (WWTP), Quyang Wastewater Treatment Plant and Zhuyuan Second Wastewater Treatment Plant all conformed to the first-order kinetics, and the measured decay rate constants at 20℃ were 0.176, 0.175 and 0.176 d-1, respectively.
