Biodegradation of Gallic Acid in Chinese Nutgall Processing Wastewater with a Sequencing Batch Reactor
The degradation of gallic acid in the Chinese nutgall processing wastewater was carried out in a sequencing batch reactor (SBR). The biodegradability of gallic acid was monitored, and the effect of initial concentration, temperature, pH, and salinity on the degradation of gallic acid was studied. Th...

| description | The degradation of gallic acid in the Chinese nutgall processing wastewater was carried out in a sequencing batch reactor (SBR). The biodegradability of gallic acid was monitored, and the effect of initial concentration, temperature, pH, and salinity on the degradation of gallic acid was studied. The result showed that the biodegradability of gallic acid was poor, but enough to meet the requirement of SBR process by further pre-treatment which would improve the biodegradability. A first-order Monod kinetic model was used to describe the degradation process of gallic acid. The removal efficiency decreased with the increase of the initial gallic acid concentration. The raise of temperature and pH were not conducive for the removal of gallic acid. When the salinity was 2 g·L-1 or less, the increase of the salinity content would improve the gallic acid removal efficiency, and the removal efficiency was higher than 75% when the salinity content was less than 10 g·L-1. |
