Abstract: The quality of coking wastewater produced after the operation of the new pressurized AS desulfurization process is analyzed. Through the optimization of the new process and the exploration of the control parameters of the coking wastewater treatment system, a commissioning scheme for the wastewater treatment is formulated, by which the parameters of the coking wastewater can be adjusted so as to meet the requirement for waste liquid discharge specification.

Key words: Coking wastewater, Biochemistry, Commissioning, As desulfurization
