A Pilot-Scale Study on Start-Up and Operation of Biofilter with Composite Media

Abstract:

According to the characteristic of high ammonia nitrogen concentration of Huaihe River in winter, a pilot-scale test was studied in this paper. This paper compared the start-up and operation performance of zeolite biofilter, quartz sand + activated carbon biofilter and zeolite + activated carbon composite biofilter in lower temperature. The results show that three kinds of biofilters for NH₄⁺-N have high remove effects. Average removal rate of zeolite biofilter, quartz sand + activated carbon biofilter, zeolite + activated carbon composite biofilter for NH₄⁺-N were 73%,64% and 78% and effluent NH₄⁺-N concentration were 0.31mg/L,0.24mg/L,0.21mg/L. Average COD_Mn removal rate of three kinds of biofilters were 5%,13% and 28%. Zeolite + activated carbon composite biofilter does not exist to NO₂-N accumulation phenomenon and showed good ability to start-up and running.
