When the biological method is used to treat organic wastewater with high salinity, the large amount of salt has a strong inhibitory effect on microbial growth. Therefore, traditional biological and physical-chemical treatment technologies are difficult to meet the standards for treating high-salinity organic wastewater. There is an urgent need to study how to strengthen the biological treatment process for the treatment of high-salt production wastewater. This study investigated the effect of activated carbon biofortification anaerobic reactor with coconut shell granular activated carbon. The study found that the optimal dosage of activated carbon was 6 g/L. The results demonstrated that mixing 2 g/L activated carbon with activated sludge before entering the wastewater treatment had a stronger treatment effect than making activated carbon and wastewater entering the reactor at the same time to contact sludge. The treatment effect of the internal circulation (IC) system with granular activated carbon under the optimized dosage and method was better than that of the IC system that was not reinforced with activated carbon with the removal rate increased by 4-10%. Activated carbon enhanced IC reactor had higher resistance to organic load impact and better chroma removal ability. These results provided reference for the treatment of similar high-salinity organic industrial wastewater. [ABSTRACT FROM AUTHOR] |
