Purification of Coke-Plant Wastewater by Means of Cold Plasma

摘要

Data regarding wastewater purification by means of cold plasma in the biochemical department at Nizhny Tagil Steel Works are analyzed in the light of new information regarding the chain oxidation of hydrocarbons and their products. In chain oxidation initiated by cold plasma, oxygen-bearing products that do not undergo chain reactions are formed. Therefore, the chemical oxygen demand of plasma-treated wastewater cannot be reduced below 300-400 mg O/L.
