Efficient nutrient removal from mixed black water is under challenge in the context of global pollution control and circular economy. The anaerobic-anorexic-aerobic process a widely used biological technology for wastewater treatment, yet its denitrification capacity limited by low biodegradable organics to nitrogen (C/N) ratio due prior degradation water. We have previously proved that weak el...
