Composite powdered carriers enhance organic elimination and sludge settleability in high-salinity petrochemical wastewater: pilot-scale performance and mechanisms
Petrochemical wastewater with high salinity and toxic organic compounds concentration will induce filamentous bulking and poor elimination efficiency. To address these issues, a pilot-scale anaerobic oxic system modified with high concentration powdered carrier biofluidized bed technology (HPB AO) was constructed with powdered carriers composed of iron-carbon powders and coal gasification slag.
