| 摘 要： | 填料的结构,材质等因素影响到生物膜的性状和水力学特性,是决定移动床生物膜反应器处理效果的关键因素。本文分别选取了5种含活性炭比例不同的填料以及一种不含活性炭的参照填料,分别从亲水性、COD与NH4+-N的去除、微生物量以及微生物种类方面对各填料在相同的运行条件下进行了比较研究。实验结果表明,含活性炭的填料在亲水性能、挂膜速度,生物量浓度等方面比不含有活性炭的填料有明显的优势。在含活性炭的填料中,25%的填料挂膜快,处理效果稳定,受外界环境影响较小。

| Abstract: | Structure,materials and other factors of the carrier affect the biofilm characteristics and hydraulic properties of water,so they are the key factors of start-up of moving bed biofilm reactor.Five kinds of carriers with different ratios of activated carbon and one without activated carbon were selected to compare the aspects of hydrophilicity,COD removal,nitrification,microbial biomass and microbial breed in the same operation condition.The results show that the carriers with activated carbon have notable a... |
