| Abstract: | This paper is on approach to the reaction principle and experiment determinationof SCN~- vs. COD interrelation value and analyze for the COD data provided by SCN~- in differ-ent process of biochemical treatment of the polluted water, which is in Beijing Coking ChemicalFactory. The paper concludes that SCN~- in the polluted water after two steps of biochemitaltreatment has been effectivelly reduced, the first step is much more effectively than second andSCN~- can not be absorbed by suspended substanced. |
