title: Organic pollution removal from coke plant wastewater using coking coal.
abstract: Coke plant wastewater (CPW) is an intractable chemical wastewater, and it contains many toxic pollutants. This article presents the results of research on a semi-industrial adsorption method of coking wastewater treatment. As a sorbent, the coking coal (CC) was a dozen times less expensive than active carbon. The treatment was conducted within two scenarios, as follows: (1) adsorption after biological treatment of CPW with CC at 40 g L(-1); the chemical oxygen demand (COD) removal was 75.66%, and the concentration was reduced from 178.99 to 43.56 mg L(-1); (2) given an adsorption by CC of 250 g L(-1) prior to the biological treatment of CPW, the eliminations of COD and phenol were 58.08% and 67.12%, respectively. The CC that adsorbed organic pollution and was returned to the coking system might have no effect on both coke oven gas and coke.
