摘要: AbstractIn this study, commingled chemical industrial wastewater was treated using a sequencing batch reactor with powdered activated carbon (PAC–SBR). The performance of the PAC–SBR system investigated under various dosages and feeding frequencies. Results showed that PAC dosage 2 g PAC/L-reactor frequency 0.25 g to 0.5 g per 3.5–7 d maintained stable long-term during operation. effects addition were also considered. Removal organic matter in demonstrated synergistic biodegradation adsorption. had better sludge volume index values (100–200) than without (150–250). This result suggested settling characteristic improved. Hence, proven increase biomass system, which improved removal oxygen demand through biodegradation. Furthermore, excitation–emission matrix spectrum s...
