Abstract

A method for treatment of coke wastewater, including (1) introducing wastewater into a regulating reservoir into which an acid liquor is added until the pH value of the wastewater ranges between about 5.5 and about 6.5; (2) introducing the wastewater into a three-dimensional electrode treatment device for electrolysis treatment; and (3) introducing the wastewater into a coagulation reaction tank into which an alkali liquor is added until the pH value of the wastewater ranges between 8 and 10, and as a coagulant polysilicate ferric magnesium is added into the wastewater for a hybrid reaction of between 5 and 15 mins; allowing the wastewater to flow into a sedimentation basin for plain sedimentation of between 4 and 6 hrs; and extracting a supernatant liquor to yield a processed effluent.
