| Abstract |
This study was conducted to remove COD_(Cr) and nutrients by using ionized gas from non-thermal plasma generator and bromide ion as fundamental physicochemical experiment for municipal wastewater treatment. Removal efficiencies of COD_(Cr). SS were not related to bromide ion concentration. The removal efficiency of SS was 90% over under all variations of bromide ion dosage. The higher bromide ion concentration, the higher removal efficiency of total nitrogen was obtained. The optimal pH for the removal of COD_(Cr). SS and T-N was at neutral pH, but that of T-P was under the alkali conditions. The optimal ionized gas flow rate for the removal of COD_(Cr) was at 7.5L/min. that of SS and T-P was almost similar under all conditions. The removal efficiency of T-N was best at ionized gas flow 2.5L/min. Therefore the influent ionized gas flow rate to remove COD_(Cr) and nutrients was suitable at 5.0L/min. Reaction time to remove COD_(Cr) and nutrients was suitable 90 to 120 minutes. Municipal wastewater treatment using ionized gas from non-thermal plasma generator and bromide ion could be considered as an effective method for organic matter and nutrients. |
