摘要
硫氰化物废水往往产生于城市煤气厂、钢铁工业的焦化厂之中,尤其是焦化厂中产生的硫氰化物废水中通常会含有较多的有毒物质,是当前很难进行生物降解的三大废水之一。为了能有效降解并去除废水中的硫氰化物,需要通过对硫氰化物的废水特点、属性进行了解,才能选择合适的处理工艺,对硫氰化物进行有效降解。为此,文章对硫氰化物废水的主要处理工艺进行分析,并对常见的问题及相应的应对策略进行了讨论,希望能实现对硫氰化物废水的高效生物降解和达标排放。
The thicyanide wastewater is often produced in the urban gas plant and steel industry coking plant,especially the thicyanide wastewater produced in the coking plant usually contains more toxic substances,which is one of the three major wastewater difficult to undergo biodegradation.In order to effectively degrade and remove thicyanide from wastewater,it is necessary to understand the characteristics and properties of thicyanide to choose the appropriate treatment process to realize the effective degradation of thicyanide.This paper analyzes the main treatment process of thicyanide wastewater and discusses common problems and corresponding strategies to attract the biodegradation and standard discharge of thicyanide wastewater.
