The influence of erythromycin on ammonia-oxidizing bacteria (AOB) and nitrite-oxidizing bacteria (NOB) was investigated using batch and continuous experiments. During the batch experiments, the impact of erythromycin was strictly dose-dependent for AOB and NOB. The continuous addition of 1mg/L of erythromycin in the long-term exposure experiment made NOB to be sensitive whereas AOB to be minimally...
To find an appropriate process for highly polluted surface water, an integrated system with a double-layer biofilter and a constructed wetland was developed. In the biofilter packed with carbon-rich ceramic granules, alternation of nitrification and denitrification was realized resulting in prominent TN (total nitrogen) removal. The constructed wetland was designed in subsurface flow mode with 0.15m...
