Biofilm accretion and start-up of active carbon biofilter
摘要
Abstract
An active carbon biofilter in intermittent filter material-washing mode on the base of active sand fil-ter,loaded with granular activated carbon as media for natural biofilm formation,was proposed in this paper. The start-up process of this active sand filter was investigated with domestic wastewater under the conditions of different hydraulic loading,0.56 m3/(m2 ·d),1.12 m3/(m2 ·d)and 2.53 m3/(m2 ·d),respectively. And the removals of COD,NH3-N,TP,turbidity and chroma were studied.The experimental results showed that active carbon biofilter could remove COD,turbidity,chroma effectively after 26 d of start-up successfully. The removal rates under the stable operation were 54%-61%,55%-76% and 71%-86%,respectively. But the removal efficiency of NH3-N and TP is not so gool as expected.The test results provide a theoretical ba-sis of active carbon biofilter for the operation of anaerobic start-up and the project practice.Compared with ac-tive sand filter in traditional filter material-washing mode,the active carbon biofilter has an obvious advantage with high-efficiency and energy-saving.关键词
