Study on Coking Wastewater Treatment by Fixed Bed of Metallization Pellets with High Carbon

Abstract:

Coking wastewater produced in the coking process is poisonous and difficult to be degraded. Coking wastewater was treated by fixed bed reactors of metallization pellets with high carbon (MPHC). In this paper, it studies the effect of removing phenols, cyanide, chemical oxygen demand（COD）and ammonia nitrogen in coking wastewater by MPHC. The results show that MPHC has good degradation effect on phenols and cyanide in coking wastewater, and the degradation rate reaches to 99.88% and 99.81% respectively; and has certain degradation effect on COD, the degradation rate is 70.61%; has poor degradation effect on ammonia nitrogen. The results of FT-IR indicate that the degradation of organic pollutants in coking wastewater by MPHC is not simply adsorption, but is removed completely.
