摘要
本文以北京焦化厂生化污水为研究对象,探讨了确定SCN^-与COD相关量的有关反应原理和方法,并对SCN^-在生化处理过程中所提供的COD值进行了分析,得出了北京焦化厂的焦化污水经生化处理后SCN^-的去除效果较好,且一段去除效果好于二段及SCN^-不被悬浮物所吸附的结论。
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.
