An intensified biofilm–electrode reactor (IBER) combining heterotrophic and autotrophic denitrification was developed for treatment of nitrate contaminated groundwater. The reactor was evaluated with synthetic groundwater (NO
3
−–N50
mg
L
−1) under different hydraulic retention times (HRTs), carbon to nitrogen ratios (C/N) and electric currents (
I). The experimental results demonstrate that high nitrate and nitrite removal efficiency (100%) were achieved at C/N
=
1, HRT
=
8
h, and
I
=
10
mA. C/N ratios were reduced from 1 to 0.5 and the applied electric current was changed from 10 to 100
mA, showing that the optimum running condition was C/N
=
0.75 and
I
=
40
mA, under which over 97% of NO
3
−–N was removed and organic carbon (methanol) was completely consumed in treated water. Simultaneously, the denitrification mechanism in this system was analyzed through pH variation in effluent. The CO
2 produced from the anode acted as a good pH buffer, automatically controlling pH in the reaction zone. The intensified biofilm–electrode reactor developed in the study was effective for the treatment of groundwater polluted by nitrate. |
