摘　　要：该实验制备了生物炭基纳米零价铁(nZVI@BC)复合材料用于厌氧氨氧化污泥的吸附固定。实验得出了nZVI@BC固有吸附性能优于生物炭,且nZVI@BC对厌氧氨氧化污泥的吸附更符合准二级动力学模型的结论,证实了nZVI@BC投加量和反应温度对其吸附固定厌氧氨氧化污泥存在显著影响。该项研究为厌氧氨氧化工艺处理低温低氮污水过程中污泥易流失问题提供了一种解决方案,具有一定的应用潜力。In this experiment,nanoscale zero-valent iron modified biochar(nZVI@BC)is developed for the absorptive immobilization of anammox sludge.nZVI@BC has better inherent adsorption characteristics than biochar.Meanwhile,absorptive immobilization of anammox sludge by nZVI@BC is more consistent with the quasi-second-order kinetic model.The dosage of nZVI@BC and reaction temperature have significant effects on absorptive immobilization of anammox sludge.This study provides a solution to the issue of sludge easy-to-lost during anammox process treating low-temperature and low-nitrogen sewage,and has certain application potential.
