“…Certainly, the type of nutrient removal in a granular biological reactor defines the type of oxygenation and the necessary operating strategy. Our group has demonstrated the ideal operating conditions in parameters such as oxygen [ 24 ], type of agitation [ 28 ], size of granular sludge [ 29 ] and appropriate operational strategies for several industrial substrates [ 23 , 25 , 30 ].…”

“…However, in many cases where AAO is used as the main process for treating industrial wastewater, several common issues have also been exposed and are worth attention [9,12]. The relevant engineering cases indicate that the removal efficiency of toxic and refractory organic compounds in industrial wastewater is very low in the anaerobic stage of the AAO [13]. When the effluent from the AAO process is discharged into the natural aquatic environment, the organic compounds/residual compounds carried in the high DO effluent enter the receiving water body, altering the aqueous solution properties (ASPs) and subjecting the ecological microorganisms to environmental stress.…”

The anaerobic-anoxic-oxic (AAO) process is one of the most widely used processes for treating industrial organic wastewater, and it has shown significant effectiveness in the removal of organic compounds, as well as denitrification and phosphorus removal. However, for the treatment of industrial organic wastewater, this anaerobic preposition and aerobic postposition process has exposed various limitations. Therefore, for this type of wastewater, the oxic-hydrolytic and denitrification-oxic (OHO) treatment process has been proposed and developed based on the principles of three-sludge separation and fluidization. This study integrated operational data from 203 coking wastewater treatment plants worldwide, and the two-step nitrification-denitrification activated sludge model No.3 (TCW-ASM3) was used for comparative analysis of the pollutant removal efficiency and total operating cost of the AAO process and the OHO process in the face of characteristic pollutants in coking wastewater. The results indicate that the full-scale OHO process achieved removal efficiencies of up to 3784 mg/L for chemical oxygen demand (COD) and 297 mg/L for total nitrogen (TN). The theoretical total cost for OHO and AAO were 9.75 and 14.38 CNY/m3, respectively. The pre-treatment aerobic process effectively reduces the biological toxicity of high-toxicity and refractory industrial wastewater, and the three-sludge system provides a stable living space for functional microorganisms, the combination of multi-mode denitrification processes offers new possibilities for treating similar types of industrial wastewater.
