摘要：

以热改性蛭石为填料，提高生物流化床系统处理低C/N污水的能力。实验结果表明，经过改性的蛭石对氨氮和COD的去除效率有明显的提高，分别是天然蛭石的2.1倍和2.7倍。在热改性蛭石为填料的生物流化床系统处理低C/N污水的实验过程中，主要分析了温度、pH和DO对反应系统处理效果的影响，确定了反应器的最佳处理条件。对于氨氮质量浓度为50 mg/L、ρ（COD）为200 mg/L的原水，在温度为30 ℃、pH=8.0、ρ（DO）=2.0 mg/L的处理条件下，反应系统对氨氮和COD的处理效果最佳，去除率分别可达94.9%和85.7%。

Abstract:

The calcining modified vermiculite was applied in a biological fluidized bed system as fillings for enhancing the organic matter removal efficiency. The experimental results showed that the modified vermiculite had better NH⁺₄-N and COD removal, which were more than 2.1 and 2.7 times of the natural vermiculite. The best treatment condition of the biological fluidized bed system with calcining modified vermiculite as fillings for low C/N wastewater treatment was determined by the effect of reaction system under a series of temperature，pH and DO. Under the environmental condition of temperature 30℃, pH=8.0, ρ（DO）=2.0 mg/L, as the inlet containing 50 mg/L of NH⁺₄-N and 200 mg/L of COD, the reaction system had the highest removal rates of NH⁺₄-N and COD, which were 94.9% and 85.7%, respectively.
