| 摘 要： | 考察沸石粉投加对活性污泥增殖及脱氨氮动力学的影响，并根据相关结论探讨了不同泥龄(SRT)条件下沸石粉的生物再生情况。结果表明，曝气池中投加沸石粉可明显提高活性污泥的产率系数和衰减系数。与传统活性污泥法相比，投加沸石粉的试验组稳定运行后，污泥产率系数和衰减系数分别提高12.5%和16.7%；当泥龄≤10 d时，出水氨氮去除率提高10%～37%，继续增加泥龄，氨氮去除率提高不明显。通过对比试验结果的关联性分析，认为在低浓度条件下，沸石中铵离子的解吸速率是沸石生物再生的限制步骤，而且再生速率与泥龄呈正相关对应关系。

| Abstract: | The effects of zeolite addition on the kinetics of activated sludge growth and ammonium removal were investigated.And according to the correlative results,the biological regeneration of zeolite were studied under different solid retention times(SRT).It was found that the values of yield coefficient and decay coefficient,which were significantly affected by the zeolite addition,were enhanced 20% and 16.8% under the same conditons as those of the traditional activated sludge process,respectively.The ammonium ... |
