碩士 === 國立臺灣科技大學 === 化學工程研究所 === 81 === Denitrification is part of biological process for removing
nitrogenous compounds from wastewater. It converts Nitrate,
Nitrire into Nitrogen using carb on source as electron donor.
In this study,we immobilized enriched denitrifica tion
microorganism with hollow fiber and used acetic acid as carbon
source to carry out the process of denitrification. Two
process were employed to treat the wastewater as follows:
(1).Microfiltration hollow fiber reactor with cr- oss flow is
applied to treat high strength nitrate industrial wastewater.
(2).Dialysis hollow fiber reactor is utilized to treat low
strength nitrate domestic wastewater. In the case of cross-
flow filtration,the volume- tric loading was 21.2 kgNitrate
per cubic meter per day with inflow water at pH=8,nitrate
loading 3000p pm,and C/N ratio1.5. The nitrate and T.O.C
removal could reach 99% and 95% ,respectively. For the
dialysis hollow fiber reactor operation, 100ppm nitrate
loading,could be reduced below 10ppm with H.R.T=0.5 hr.
