摘要
对多孔型悬浮生物陶粒的物理性质及应用于曝气生物滤池在再生水处理中的应用效果进行了系统研究,并与纤维束滤池进行了运行效果比较。结果表明:多孔型悬浮生物陶粒具有挂膜快、生物亲和性好、孔隙率高、比表面积大等优点;用于再生水处理时,出水COD_G和NH_4^+-N值分别在20mg/L和10mg/L以下,处理效果优于纤维束滤池。
The physical properties of globular suspended granular ceramics and the effects of the reclaimed water treatment by biological aerated filter were studied. The effects of the globular suspended granular ceramics was compared with the fibre filter. Results showed that the globular suspended granular ceramics had advantages of faster membrane formation, better affinity, higher porosity and bigger surface area. When globular suspended granular ceramics were used in reclaimed water treatment, the CODe, and ammonia nitrogen concentration in the effluent were below 20mg/L and 10mg/L, respectively. The effects of the globular suspended granular ceramics Falter were better than that of the fibre falter.
