Study of The Treatment of Coking Wastewater by Biological Nitrogen Removal with Physical-Chemical Process

摘要

Coking wastewater component complex is difficult to treat and yet unable to achieve the emission target by biological treatment, thus needs further processing. Wastewater treatment plant of coking plant in Bao Gang applied A/0 process in biological treatment, used special treatment agent -Ml 80 by coagulation and sedimentation process. Through treatment, the parameters reached the first grade of GB13456-92. It is of great reference significance for process debug and operation of the coking wastewater treatment system.
